In February 2000, C-SPAN released its first major poll of presidential historians and political scientists. Ulysses Grant placed 33rd of 41 ranked presidents. He sat below Calvin Coolidge, below Chester Arthur, below Benjamin Harrison, below Rutherford Hayes. The 2000 result echoed a verdict that had calcified over a century: Grant was a great general who failed in the White House, a tippler surrounded by thieves, a credulous figurehead presiding over what Henry Adams called an administration that “outraged every rule of ordinary decency.”

Twenty-four years later, the 2024 Presidential Greatness Project Expert Survey placed Grant at 17th. The 2024 APSA panel landed him at 18th. The shift was not marginal. Grant had crossed from the lower third into the upper middle of historian placements, displacing presidents whose reputations had been considered fixed. No other post-Civil War president has moved that far in that direction. Coolidge climbed a few slots and stalled. Hoover has been unsuccessfully resuscitated five times. Eisenhower rose from twenty-second to a stable upper-tier slot, but that climb began in the 1970s and was complete by 2000. Grant’s reappraisal is the rare case of a reputation reversed within a single generation of working historians.

The reversal was not driven by changing fashion or by a thawing of partisan resentment. It was driven by archives, by three specific books, and by the collapse of the academic regime that had constructed Grant’s bad reputation in the first place. The Lost Cause apparatus and the Dunning School at Columbia, working in tandem from roughly 1907 through the 1950s, produced the historiographic frame inside which Grant looked like a failure. When that frame dissolved between 1965 and 2000, the evidentiary base for the old verdict dissolved with it. What replaced it was a substantially different president: a chief executive who deployed federal power against political violence in the South at a scale unmatched until the 1960s, who signed the most ambitious rights legislation between Reconstruction and the Lyndon Johnson era, and who suspended habeas corpus in peacetime to prosecute domestic terrorism. That president had been there in the documents the whole time. The historiographic regime had simply been organized not to see him.

This article reconstructs how the reappraisal happened, names the books and archives that drove it, and adjudicates whether Grant’s current ranking around 17th is too high, too low, or roughly correct. The verdict matters because Grant’s case is the cleanest available demonstration of a thesis that applies to every presidential reputation: ranking is downstream of the academic regime that interprets the evidence, and when the regime changes, the placements change with it. Wikipedia cannot tell you this story because Wikipedia is constrained to summarize current consensus. The story is about how the consensus moved.

The Caricature That Held for a Century

Before 1960, the standard portrait of Grant in American political memory was assembled from three components that had been welded together so tightly that they read as a single judgment. He was, the consensus held, a drunk who could not control himself, a corrupt manipulator or hopeless naif who allowed thieves to plunder his administration, and an incompetent president who lacked the political skills of his predecessor and successor alike. Henry Adams, writing in 1907, had set the tone with a sentence that became almost a slogan among historians: “The progress of evolution from President Washington to President Grant, was alone evidence enough to upset Darwin.” Adams was writing for effect, but the formulation traveled. By the time Allan Nevins had cemented the standard interpretation in his 1932 study, the caricature had become academic doctrine.

Each of the three charges had a kernel of fact wrapped in substantial exaggeration. Grant did drink, and at certain documented moments in his pre-war career he drank heavily. But the assertion that he was drunk while serving as president, repeated for decades in textbook treatments, has no contemporary documentary support. His White House physician, his cabinet members, and his political opponents in Congress did not make this charge in writing while he was in office. The drunk-president story congealed in retrospective memoir literature and was repeated as fact by writers who had not examined the contemporary documentation.

The corruption charge was more substantial but conflated two genuinely different phenomena. There were major scandals during Grant’s two terms. The Whiskey Ring, the Credit Mobilier exposure, the Belknap impeachment, the Black Friday gold corner of September 24, 1869, and the Indian Ring scandals at the Department of the Interior were all real, all documented, and all damaging. The kernel was fact. The exaggeration was the attribution: in the documentary evidence, Grant himself was not implicated in financial corruption. His personal accounts at his death showed him broke, scammed by his son’s business partner Ferdinand Ward in the 1884 collapse that left him penniless and led him to write his Memoirs to pay off creditors. The man whose administration produced large-scale theft from the national government died with debts that consumed everything he owned. That biographical detail did not fit the caricature, so the caricature ignored it.

The incompetence charge was the loosest of the three and the one that depended most on the Dunning School’s specific interpretive paradigm. Within that frame, Grant’s signature policies, the Enforcement Acts, the prosecution of the Klan, the 1875 Civil Rights Act, the support for federal protection of Black voting rights in the South, were not achievements at all. They were misguided, vindictive Northern aggressions that prolonged sectional bitterness and delayed national reconciliation. When the Dunning School’s frame collapsed, those same policies became the basis on which Grant was rehabilitated. Same evidence. Different frame. Different verdict.

How the Dunning School Made the Verdict

William Archibald Dunning arrived at Columbia in 1886 and began producing the dissertations that would calcify into a school of Reconstruction historiography by roughly 1907. Dunning himself was not a particularly hostile writer; his prose was measured and his archival work was real. The partisan content of the Dunning School came mostly from his students, who fanned out into history departments across the South and Midwest and produced state-by-state Reconstruction studies during the 1910s and 1920s. Walter Lynwood Fleming wrote on Alabama. James Wilford Garner wrote on Mississippi. Joseph Gregoire de Roulhac Hamilton wrote on North Carolina. The state studies followed a template: corrupt governments of that era imposed by Northern bayonets, “carpetbaggers” and “scalawags” exploiting freed Black voters who were politically incompetent, eventual redemption by white Democratic forces restoring legitimate self-government.

Within this template, Grant played a specific role. He was the federal president whose troops propped up the governments of that era, whose Enforcement Acts criminalized resistance to them, whose Justice Department prosecuted the white Southerners who organized against them. The Klan, in the Columbia school’s reading, was a regrettable extralegal response to provocation, not a paramilitary terrorist organization carrying out political violence; Grant’s prosecution of the Klan was therefore overreach against citizens defending their communities from misrule. The frame inverted what the prosecutions actually were. Inside the paradigm, Grant’s rights enforcement record looked like vindictive failure. Outside the paradigm, it would eventually look like one of the most ambitious uses of federal executive power for civil rights ends in American history.

The Columbia school traveled fast because it had infrastructure. The United Daughters of the Confederacy, founded in 1894, ran a parallel apparatus of textbook influence and historical-marker placement that aligned with the Columbia school interpretation. Mildred Lewis Rutherford, the UDC’s historian general from 1911 to 1916, produced explicit instructions to Southern teachers on which textbooks to reject and which interpretations to teach. Claude Bowers, a journalist and Democratic Party operative, published “The Tragic Era” in 1929 to mass-market success; the book applied the Columbia school interpretation in prose accessible to general readers and became the standard popular account for two decades. James Ford Rhodes, in his multi-volume “History of the United States from the Compromise of 1850,” gave the Dunning interpretation Pulitzer-Prize-winning scholarly respectability. The frame was not a fringe view. It was the consensus inside professional history.

The frame’s grip on presidential rankings showed up immediately when Arthur Schlesinger Sr. ran the first formal historian poll in 1948. Grant placed 28th of 29 ranked presidents, ahead of Warren Harding and below everyone else. Schlesinger’s panel of 55 historians was drawn from leading research universities; the verdict was not idiosyncratic. The 1962 Schlesinger poll produced essentially the same result: Grant at 30th of 31, with only Harding lower. The Murray-Blessing poll of 1982 placed Grant 28th. Robert Schlesinger Jr.’s 1996 update placed him 29th. C-SPAN’s first historian survey in 2000 placed him 33rd. For roughly half a century, across multiple polling methodologies and historian generations, Grant occupied the bottom ten of every ranking. The verdict felt fixed.

It was not fixed. It was a function of the regime that had produced it.

The Collapse of the Frame, 1935 to 1988

The Columbia school’s collapse took roughly fifty years and proceeded in three phases. The first phase, from 1935 through about 1955, produced the foundational scholarly challenge but failed to dislodge the consensus because the challenger was Black. The second phase, from roughly 1955 through 1975, saw white historians at major universities adopt and develop the challenge, with Kenneth Stampp’s 1965 “The Era of Reconstruction” serving as the institutional turning point. The third phase, from 1975 through 1988, saw the new interpretation become the consensus, culminating in Eric Foner’s “Reconstruction: America’s Unfinished Revolution” (1988), which replaced the Dunning template as the standard scholarly account.

W.E.B. Du Bois published “Black Reconstruction in America” in 1935. The book was a comprehensive refutation of the Columbia school, built on extensive archival work, contemporary documentation, and a Marxist analytical frame that read Reconstruction as a thwarted democratic revolution rather than a tragic occupation. Du Bois named specific things the Dunning School had refused to see: the substantial achievements of biracial Reconstruction governments in establishing public schools, the genuine democratic participation of freed Black voters, the systematic violence by which white Democratic forces had overturned those governments, the federal complicity in retreat. The book also contained a chapter on Grant that anticipated by sixty years what Brands and Chernow would eventually write. It treated Grant’s civil-rights enforcement as a major federal achievement that white historiography had been organized not to credit.

“Black Reconstruction” was reviewed politely in mainstream journals and then ignored. The white historical establishment did not engage its argument. Du Bois’s book remained influential within Black scholarship and inside specific networks at the historically Black colleges, but it did not move the consensus at Columbia, Yale, or Harvard. The Schlesinger Sr. poll of 1948 ran with the Dunning paradigm intact even though Du Bois’s refutation had been in print for thirteen years.

The paradigm began to move in the late 1950s, when civil rights activism made the Dunning School’s political content embarrassing. C. Vann Woodward’s “The Strange Career of Jim Crow,” published in 1955, traced the post-Reconstruction segregation regime to the 1890s rather than to any natural Southern racial order, undermining the Dunning narrative’s assumption that legal segregation was an inevitable Southern condition that Reconstruction had wrongly attempted to disrupt. John Hope Franklin’s “Reconstruction After the Civil War” (1961) provided the first widely adopted textbook treatment that broke with the Dunning template at a major commercial publisher. But the institutional turning point came with Kenneth Stampp.

Stampp was a professor at Berkeley with an established scholarly reputation. His 1965 book “The Era of Reconstruction” reread the same archives the Columbia School had used and arrived at substantially opposite conclusions. The Reconstruction governments had been more competent and less corrupt than the Dunning state studies claimed. The Klan had been a domestic terrorist organization, not a regrettable response to provocation. Federal enforcement of civil rights had been a genuine and substantive achievement that had been undone by white Southern violence and Northern partisan retreat, not by the misguided ambition of Northern occupiers. Stampp’s book moved the discussion. He was at Berkeley. He was white. He had tenure. He could not be marginalized the way Du Bois had been.

The 1970s saw a wave of revisionist Reconstruction scholarship by historians who had absorbed Stampp’s reframing. By the early 1980s the field had largely abandoned the Dunning paradigm, though the reframing had not yet been consolidated into a single canonical work. Eric Foner’s “Reconstruction: America’s Unfinished Revolution” (1988) provided that consolidation. The book ran to 690 pages of dense scholarly prose. It worked through the entire period with the new interpretive frame in place. Federal enforcement was a genuine and substantively defensible attempt to establish multiracial democracy; its failure was attributable to white Southern violence, Northern political withdrawal, and the structural limits of nineteenth-century federal administrative capacity rather than to overreach or naivete. Grant, in Foner’s reading, was an essentially honorable president whose rights protection commitments had been substantial and whose failures had been overdetermined by forces larger than his own decisions.

Foner’s book replaced the Dunning paradigm as the standard scholarly reference. Graduate seminars taught from it. Textbook authors who needed a citation for Reconstruction interpretation used Foner. Within a decade of publication, the Dunning template had become the historiographic position one named in order to refute rather than the consensus one assumed. The interpretation had moved. The basis on which Grant had been ranked 30th was being dismantled.

The Ranking Trajectory, Survey by Survey

The shift in scholarly interpretation took some time to register in presidential placement surveys. Polls aggregate the views of historians who do not all specialize in the period being judged. A specialist on Truman or Reagan who participates in a presidential placement poll uses his or her overall historical sense to place Grant, and that overall sense lags the specialist literature. The reappraisal therefore showed up first in specialist Reconstruction writing during the 1970s and 1980s, then in textbook revisions during the 1990s, and only finally in ranking poll results during the 2000s and 2010s. The lag is structural, not idiosyncratic. It is visible across other consensus-flip cases including Eisenhower’s reappraisal and Truman’s rehabilitation.

The Schlesinger 1948 poll placed Grant 28th of 29 ranked presidents (only Harding lower). The Schlesinger Sr. 1962 poll placed him 30th of 31 (only Harding lower). The 1970 Maranell poll placed him low. The Murray-Blessing 1982 poll placed him 28th of 36. The Schlesinger Jr. 1996 New York Times Magazine poll placed him 29th. The Ridings-McIver 1997 poll placed him 32nd. These results, spanning forty-eight years, sit inside a single interpretive frame. The numbers move by one or two places but never break out of the bottom ten.

The C-SPAN survey of February 2000 placed Grant 33rd of 41. Siena College’s 2002 poll placed him 29th of 39. The first signal of movement appeared in the C-SPAN 2009 survey: Grant climbed to 23rd of 42, a jump of ten places from the 2000 result. The C-SPAN methodology had not changed. The pool of participating historians was somewhat refreshed but largely overlapping. What had changed was the underlying scholarly opinion they were aggregating. The Dunning frame, by 2009, was an interpretive position one explicitly argued against; the Foner frame was the assumed background.

The Siena 2010 poll placed Grant 26th, a smaller move than C-SPAN’s but still upward. C-SPAN 2017 placed him 22nd of 43. Siena 2018 placed him 24th. C-SPAN 2021 placed him 20th of 44. Siena 2022 placed him 22nd of 45. The Presidential Greatness Project (Rottinghaus and Vaughn) ran surveys in 2014, 2018, and 2024; the 2014 result placed Grant 24th, the 2018 result 24th, the 2024 result 17th. The APSA-affiliated 2024 panel placed him 18th.

The trajectory therefore reads: 28th in 1948, 30th in 1962, 28th in 1982, 29th in 1996, 33rd in 2000 (a brief reversal that did not reflect new scholarship), 23rd in 2009, 22nd in 2017, 20th in 2021, 17th in 2024. The reader who plots this on a chart with the C-SPAN, Siena, and Presidential Greatness Project surveys layered together will see a flat line through 2000 followed by a steady climb through the 2010s and a sharp jump in the 2024 cycle. The 2024 jump corresponds to the diffusion through the historian pool of Chernow’s 2017 Grant biography, which functioned as the popular acceleration of a scholarly reappraisal that had been underway since the 1980s.

The annotated ranking chart that accompanies this article plots every major survey from 1948 through 2024 with the specific scholarly events that moved the consensus marked at their publication dates. Du Bois 1935. Stampp 1965. Franklin 1961. Foner 1988. Brands 2012. Chernow 2017. Calhoun 2017. Reading the chart, the publication of a major work consistently precedes a placement shift by between two and seven years, with the diffusion lag determined by how widely the book circulates outside the specialist community. The most striking visualizable pattern is the flat line through 2000 followed by the climb. The climb is not an organic shift in vibe. It is an evidentiary cascade with specific named books at its origin.

The Memoirs: The Primary Source That Outlasted the Caricature

Among the documents that shaped the eventual reappraisal, Ulysses Grant’s own Personal Memoirs occupy a peculiar position. The two-volume work was written between June 1884 and July 1885, completed days before his death from throat cancer on July 23, 1885. Mark Twain published the volumes through his Charles L. Webster and Company imprint in December 1885 and March 1886, with the work eventually generating royalties of roughly $450,000 for Julia Grant (equivalent to several million in current dollars). The Memoirs sold over 300,000 copies in their first year, an extraordinary commercial success that produced one of the most widely circulated political autobiographies of the nineteenth century.

The Memoirs do not address Ulysses Grant’s presidency directly. The narrative concludes with the surrender at Appomattox in April 1865 and Grant’s brief postwar service. Critics during the Dunning era treated this absence as evidence that the author was avoiding the political record that they considered indefensible. The post-Foner literature has read the same absence differently. Grant was dying when he wrote, racing to finish a book that would secure his family’s finances after the 1884 Ferdinand Ward bankruptcy had left him penniless. He had limited time and chose to focus on the military record where his contributions were widely conceded and where he could move quickly through familiar material. The decision to bracket the presidency was a practical one, not a confession of failure.

The Memoirs’ actual content matters for the reappraisal because the prose itself contradicts the caricature of an inarticulate, befuddled commander. The writing is clear, direct, and analytically sophisticated. Edmund Wilson, in his 1962 study of Civil War literature “Patriotic Gore,” placed the Memoirs in the front rank of nineteenth-century American prose. Twain himself declared the work a literary achievement equal to anything in the language. The man who produced this prose was not the lumbering incompetent of the Lost Cause caricature. The Memoirs, as a primary source about their author, document a different person from the one the Dunning paradigm had described.

The Memoirs also document Ulysses Grant’s actual positions on the questions of slavery and race in the war. He described slavery as the cause of the war directly and without equivocation, in language consistent with what the post-Foner literature has restored as the mainstream interpretation. The conclusion is worth attending to because it predates the post-Foner consensus by a century: “The cause of the great War of the Rebellion against the United Status will have to be attributed to slavery.” Subsequent paragraphs developed the analysis with substantive detail. The autobiographical Grant was not the figure who had stumbled into civil-rights enforcement reluctantly; he was the figure who understood from the beginning what the war had been about and what the postwar period required.

The Memoirs were available in print continuously from 1886 to the present. Their evidence about their author was available to every Dunning-era historian. The fact that the Dunning interpretation could be sustained for half a century alongside the Memoirs’ continuous availability is itself evidence for the historiographic regime thesis. Primary sources do not by themselves overturn interpretive frames; they have to be read inside a perspective that takes them seriously. The Dunning frame read the Memoirs as the work of a great general who had stumbled in politics; the post-Foner interpretation reads them as the autobiography of a coherent figure whose military and political careers expressed the same character. Same document. Different readings.

Brands: The First Major Rehabilitation Biography

H.W. Brands published “The Man Who Saved the Union: Ulysses Grant in War and Peace” in 2012. The book ran to 736 pages and offered the first major popular biography of Grant in roughly twenty years to take the post-Foner scholarly frame seriously. Brands was already a widely read presidential biographer, having published books on Andrew Jackson, Franklin Roosevelt, and Benjamin Franklin. His Grant biography reached the audience that does not read specialist Reconstruction monographs but does buy popular presidential biographies. The book’s reception in mainstream press reviews legitimized the rehabilitation outside the academy.

Brands’ specific argument was that the conventional separation of Grant’s military career from his presidency was historically misleading. The same Grant who had won the war by methodical attrition and refusal to be panicked by setbacks had governed by the same methods. His presidency had succeeded where it was allowed to succeed (the prosecution of the Klan in 1871 and 1872) and had been defeated where the partisan coalition for civil-rights enforcement collapsed under economic pressure (the Panic of 1873) and Northern fatigue. The corruption scandals were real but were a separate analytical question from the question of Grant’s policy commitments and his administration’s substantive achievements.

The book’s framing positioned Grant as the indispensable figure in two American transformations: the military defeat of the Confederacy and the brief attempt to construct a multiracial democracy in the South. The first was widely conceded; Grant’s stature as a general had survived even the Columbia School’s worst treatment of his presidency, because military reputation in the United States is largely independent of political reputation. The second was Brands’ argument that needed making, because it was the part of Grant’s record that the Dunning paradigm had been organized to suppress. Brands argued that the suppression had not been incidental. The downgrading of Grant’s presidency had been functionally connected to the downgrading of Reconstruction’s achievements; one could not be rehabilitated without the other.

Brands was reviewed widely. The book did not sell at Chernow numbers, but it sold enough to move the conversation. It also functioned as the immediate predecessor and intellectual scaffolding for the Chernow biography five years later. By 2012 the Foner-era scholarship had been available for nearly a generation, but no major popular biographer had synthesized it into a cradle-to-grave narrative for general readers. Brands did that. The 2014 Presidential Greatness Project survey, conducted shortly after Brands’ publication, showed Grant at 24th, a modest improvement over previous Siena and C-SPAN results. The momentum was building.

Chernow: The Popular Accelerator

Ron Chernow published “Grant” in October 2017. The book ran to 1,074 pages. Chernow’s previous biographies of Alexander Hamilton and George Washington had each sold over a million copies in the United States and had won the National Book Critics Circle Award and the Pulitzer Prize respectively. “Hamilton” had also generated the Broadway musical that placed Chernow at the center of American popular historical writing. When Chernow published a biography, it was reviewed by every major American publication. The book got the treatment.

Chernow’s Grant pushed the rehabilitation further than Brands had. Where Brands had argued that the corruption scandals were a separate analytical question from Grant’s policy record, Chernow argued more aggressively that Grant himself had been substantially less responsible for the scandals than the conventional account claimed. The Whiskey Ring had been exposed by Treasury Secretary Bristow during Grant’s administration with Grant’s own initial approval; the subsequent White House interference came primarily through Grant’s personal secretary Orville Babcock and Grant’s loyalty to a man who had served him as a wartime aide. The Credit Mobilier exposure had implicated Vice President Schuyler Colfax in events that occurred before he became vice president and before Grant assumed the presidency. The Belknap impeachment had concerned actions by a cabinet secretary in office, but Grant had accepted Belknap’s resignation upon learning of the allegations. Chernow’s pattern argument was that Grant had been credulous about specific men he trusted, particularly those who had served him in the war, but that credulity was different from complicity, and that the conventional account had conflated the two.

The rights enforcement record received Chernow’s most extensive treatment. He devoted substantial chapters to the 1870 and 1871 Enforcement Acts, to Attorney General Akerman’s prosecution campaign, to the October 17, 1871 habeas corpus suspension in South Carolina, and to the 1875 Civil Rights Act. The narrative made the case that this record constituted a major presidential commitment to multiracial democracy that had been overdetermined by economic collapse and partisan retreat but had not been a failure of Grant’s own commitment. Chernow’s prose was novelistic in the manner that had made his earlier biographies bestsellers. The book reached the public.

The book also reached historians who participate in presidential ranking polls without specializing in Reconstruction. A historian who specializes in twentieth-century foreign policy and reads Chernow as her major recent encounter with Grant’s record will rate him higher in the next ranking poll than she would have rated him before reading the book. Multiply this effect across the historian community and you produce the 2024 jump from 20th in C-SPAN 2021 to 17th in the Presidential Greatness Project 2024. The shift is mechanistically traceable to the diffusion of a single book through the panel of historians who participate in these surveys.

There is a more critical view of Chernow’s book that deserves naming. Some specialist reviewers, including the Reconstruction historian Brooks Simpson, argued that Chernow’s rehabilitation moved too far in the corrective direction; Grant’s failures, in this view, were not solely overdetermined by external circumstances and Chernow’s narrative tended to soften culpability where the documentary evidence was harder. The book’s commercial reach also meant that its specific interpretive choices, including its readings of contested episodes, became widely circulated in the general public’s understanding of Grant in ways that prevented the more nuanced scholarly debate from registering. Whether one views these effects as costs or as the inevitable price of popularization, the placement shift is what it is. Chernow’s book moved the consensus.

Calhoun: The Scholarly Foundation

Charles Calhoun published “The Presidency of Ulysses S. Grant” in 2017, the same year as Chernow. The book was the entry in the University Press of Kansas’s American Presidency Series, the scholarly series that produces detailed treatments of each presidency for the academic market. Calhoun’s book ran to 720 pages of dense archival work and was reviewed primarily in specialist journals. It sold a small fraction of what Chernow’s book sold. But within the historian community it served a different and arguably more important function: it provided the rigorously documented scholarly foundation for the popular rehabilitation that Brands and Chernow had advanced.

Calhoun had been working on Grant and his partisan coalition for two decades before the 2017 book. His earlier “Conceiving a New Republic: The Republican Party and the Southern Question, 1869-1900” had established the political-coalition framework within which Grant’s presidency had operated. Calhoun’s interpretive position differed in emphasis from Foner’s: where Foner stressed the structural failure of Reconstruction’s ambitions, Calhoun stressed the partisan coalition that had sustained Grant’s civil-rights enforcement and the specific coalitional erosion that had ended it. The two interpretations were compatible but emphasized different aspects of the same outcome.

The 2017 book treated Grant’s presidency systematically. The Reconstruction record received the heaviest treatment, but Calhoun also produced what is probably the best available scholarly account of Grant’s foreign policy (the Treaty of Washington with Britain, the failed Santo Domingo annexation attempt, the Cuban crisis), his Indian policy (the so-called Peace Policy and its mixed results), and his fiscal policy (the return to the gold standard, the Specie Resumption Act of 1875). The point of the systematic treatment was that Grant’s presidency had been substantive across multiple policy domains, not merely competent on civil rights and otherwise disastrous. The conventional caricature had reduced the entire administration to its scandals; Calhoun’s book restored the policy texture.

The book’s effect on the historian community was substantial but slow. Specialist reviews appeared in 2018 and 2019. Citations began appearing in the literature within two years. The 2024 Presidential Greatness Project survey, which produced the 17th-place result, reflected the diffusion of Calhoun’s scholarly foundation along with the popular acceleration provided by Chernow. The two books worked together: Chernow reached the public and the non-specialist historians; Calhoun anchored the rehabilitation in archival work that would have to be addressed by any future scholarly challenge.

Beyond Civil Rights: The Domains the Rehabilitation Restored

The case for the upward revision rests primarily on the rights enforcement record, but the wider Calhoun-led scholarly restoration also returned attention to several policy domains where the Dunning era had assigned failure or silence. The expanded view does not change the broad ranking arithmetic dramatically, but it strengthens the case for placing Grant in the upper middle of the historian rankings rather than the lower third by adding substantive achievement in domains beyond the central enforcement record.

The 1871 Treaty of Washington negotiated under Secretary of State Hamilton Fish settled the most dangerous outstanding dispute with Britain, the Alabama Claims arising from the British construction of Confederate commerce raiders during the war. The settlement created the precedent for international arbitration of major-power disputes that would become a cornerstone of nineteenth-century diplomatic practice. The 1872 Geneva Tribunal awarded the United States $15.5 million in compensation, an outcome that vindicated the legal theory the American negotiating team had advanced. The diplomatic achievement has been substantively undervalued in conventional treatments of the Ulysses Grant administration because the Dunning paradigm had no interpretive use for it; it sits outside the Reconstruction debate that organized that frame. The post-Foner scholarship has returned Fish’s tenure and the Washington Treaty to the position of significance the contemporary documentation supports.

The 1869-1870 attempt to annex the Dominican Republic (then called Santo Domingo) is a more contested case. The project was driven by President Ulysses Grant’s vision of a Caribbean refuge for African Americans and a strategic naval base, and was negotiated through a Treaty signed in 1869 that the Senate rejected in 1870 after vigorous opposition led by Senator Charles Sumner. The contemporary record shows the project as a substantial presidential commitment that absorbed political capital and damaged the Sumner relationship; assessments of the project’s wisdom remain divided. Brands treats it as well-intentioned but politically misjudged; Chernow gives somewhat more weight to the strategic logic; Calhoun emphasizes the racial-egalitarian motivation as distinguishing it from straightforward imperial expansion. The rejection is best treated as one of the genuine policy failures of the first term, but as a failure of a different character from the corruption scandals.

The Indian Peace Policy launched at the beginning of the administration sought to replace military administration of relations with the tribes with religious-denominational administration under the theory that religious agents would be more honest and more humanitarian than the political appointees who had previously held those positions. The Peace Policy produced mixed results: corruption was reduced but not eliminated, military conflicts continued including the catastrophic 1876 events at the Little Big Horn, and the underlying framework of forced assimilation through reservations and boarding schools was not challenged. Recent scholarship has been more critical of the assimilationist framework than the post-Foner consensus initially was, raising new questions about whether the Peace Policy should be treated as a substantive reform attempt or as a kinder-gentler version of policies that produced similar long-term harms. The scholarly question is open. The rehabilitation does not depend on a positive verdict on the Peace Policy; the Indian record is treated by most contemporary specialists as a domain where the administration’s reform intentions were genuine but inadequate to the underlying structural problems.

The Specie Resumption Act of January 1875 committed the national government to redeeming Civil War-era greenbacks in gold beginning January 1, 1879. The act was politically controversial at the time, with Western and agrarian interests opposing it as deflationary while Eastern financial interests supported it. The post-war return to the gold standard was a major fiscal-policy achievement that the contemporary record credits to the administration, working with congressional Republicans including John Sherman. Conventional treatments before 2000 had largely ignored the fiscal record because the Dunning paradigm had organized attention around the Reconstruction-failure narrative and had no interpretive use for the resumption story. Calhoun’s scholarship restored the fiscal achievement to the position the documentary evidence supports.

The 1872 Yellowstone National Park Act and the broader conservation precedents established during the administration are smaller-scale achievements that have received increased attention in recent literature. The signing of the Yellowstone act on March 1, 1872 created the first national park anywhere in the world and established a precedent the Theodore Roosevelt administration would build on extensively. The conservation record is not central to the placement question but adds another domain of substantive policy achievement that the Dunning paradigm had bracketed.

The Klan Trials: What the Court Records Show

The federal court proceedings against Klan defendants during 1871 and 1872 constitute one of the most extensive prosecutorial campaigns in nineteenth-century American legal history, and their records form an essential primary source for assessing what the prosecution effort actually accomplished. The South Carolina trials at Columbia in November and December 1871 produced the largest single concentration of cases, with over 500 indictments handed down by federal grand juries and most defendants either convicted or pleading guilty by year’s end. Judge Hugh Lennox Bond, riding circuit, presided over the most prominent prosecutions. The trial transcripts, preserved in the National Archives Southeast Region, contain extensive sworn testimony from victims, perpetrators, and witnesses that documents the systematic political violence in granular detail. The testimony of Henry Lipscomb, Caroline Smith, Jackson Surratt, and dozens of other Black witnesses provides one of the largest contemporary documentary evidences of paramilitary violence anywhere in the nineteenth-century world.

The Mississippi trials were less extensive but reached similar conclusions about the systemic nature of the violence. Federal District Judge Robert Hill presided over the major Mississippi prosecutions. The North Carolina trials, focused on the killing of state senator John Stephens by Klan members in Caswell County in May 1870, produced convictions that the state courts had refused to obtain. The Tennessee, Alabama, and Georgia federal prosecutions were smaller in scale but followed the same pattern: federal grand juries returning indictments where state grand juries had refused, federal trial courts producing convictions where state courts had acquitted, federal marshals making arrests that state authorities had declined to make. The institutional achievement was the demonstration that federal authority could enforce civil rights law against organized white-supremacist violence where state authority could not or would not.

The convictions did not last in terms of sentences served. Many of those convicted received relatively short prison sentences or were pardoned during the political retreat of 1873 and 1874. President Ulysses Grant himself issued numerous pardons during this period, a fact that critics of the prosecution campaign sometimes cite as evidence of inconsistency. The pardons reflected the collapse of the partisan coalition for sustained punishment rather than a reversal of the prosecution commitment itself; the prosecution campaign had been politically possible in 1871 and 1872 and was no longer politically possible by 1874. The pardons, in this reading, were an acknowledgment of changed political reality rather than a repudiation of the original prosecutions.

The Klan trial records were available in the National Archives throughout the Dunning era. They were not classified or restricted. They were simply not consulted by historians whose interpretive frame had no use for what they documented. The reappraisal involved going back to records that had been sitting in their archival boxes since the 1870s and reading them inside a frame that took the documented violence seriously. The records had not changed. The reading had.

Reopening the Documentary Record

The rehabilitation rested on documents that had been available the whole time but had not been integrated into a popular narrative until the 2010s. The First Enforcement Act of May 31, 1870 made it a federal crime to interfere with the right to vote on the basis of race. The Second Enforcement Act of February 28, 1871 strengthened federal supervision of elections in larger cities. The Third Enforcement Act of April 20, 1871, popularly known as the Ku Klux Klan Act, made it a federal crime to deprive a person of equal protection of the laws and authorized the president to suspend habeas corpus to enforce its provisions. The Civil Rights Act of March 1, 1875 prohibited racial discrimination in public accommodations and was the last major national rights legislation until the 1957 act.

Grant’s October 17, 1871 proclamation suspending habeas corpus in nine South Carolina counties was the only peacetime suspension in the nineteenth century. The proclamation was issued after Attorney General Amos Akerman had presented Grant with evidence of Klan terror in the up-country South Carolina counties, where U.S. officials and Republican voters had been the targets of organized killings. The suspension allowed federal marshals to arrest suspected Klansmen without indictment. The arrests led to the prosecutions that produced, by the end of 1872, over three thousand federal indictments and over six hundred convictions in Klan-related cases. The numbers are documented in Department of Justice records and in the contemporaneous reports of U.S. district attorneys.

This record had been visible in archival form for a century. The Dunning frame had simply not treated it as a positive achievement. Within the Dunning paradigm, three thousand indictments looked like federal overreach against Southern self-defense; the habeas corpus suspension looked like dictatorial intrusion into civil liberties. Within the post-Foner paradigm, three thousand indictments looked like an unprecedented national commitment to civil-rights enforcement; the habeas corpus suspension looked like emergency executive power exercised to confront domestic terrorism. The documents had not moved. The frame had moved.

The Grant annual messages between 1870 and 1875 provide the contemporaneous record of how he himself understood the prosecution campaign. His December 1871 annual message described the Klan as a conspiracy whose object was “by force and terror, to prevent all political action not in accord with the views of the members, to deprive colored citizens of the right to bear arms and of the right of a free ballot, to suppress the schools in which colored children were taught, and to reduce the colored people to a condition closely allied to that of slavery.” The language is direct and the analysis is accurate. Grant understood what the Klan was. He acted accordingly. The contemporaneous prose has been available in the Congressional Globe and the published presidential messages for nearly 150 years.

The 1875 Civil Rights Act, signed by Grant on March 1, 1875, prohibited racial discrimination in public accommodations including hotels, theaters, and public conveyances. The Supreme Court struck it down in the Civil Rights Cases of 1883 by an 8-1 vote (Justice John Marshall Harlan dissenting). The act’s brief life and judicial nullification have often led to its dismissal as a paper achievement. But the bill’s passage required substantial electoral work, occurred at a moment when the Republican coalition for civil-rights enforcement was already collapsing, and represented the high-water mark of national civil rights commitment between Reconstruction’s effective end in 1877 and the 1957 Civil Rights Act. Grant’s role in pushing for the bill, in working with Senator Charles Sumner before his death in 1874, and in signing it during his lame-duck period (with full knowledge that the incoming electoral configuration would not support similar legislation) is documented in his correspondence and in the legislative record. The reappraisal restored this record to public memory.

The records of Attorney General Amos Akerman’s tenure (June 1870 to December 1871) are particularly important to the rehabilitation. Akerman was a Georgia Republican who had served briefly in the Confederate Army before becoming a Reconstruction Republican; his commitment to enforcement was personal and ferocious. His prosecutorial campaign in 1871, working with the new Department of Justice that had been created in June 1870, produced the bulk of the Klan prosecutions. Akerman was forced out of office in December 1871 under pressure from railroad interests who opposed his refusal to favor their litigation, but his successor George Williams continued the prosecution campaign through 1872. The institutional history of the early Department of Justice, established in 1870 specifically to enable the federal prosecution campaign, has been reconstructed in detail in the post-Foner literature and forms part of the basis for the rehabilitation.

The Lost Cause Apparatus and Its Slow Decay

The Dunning School was the academic component of a larger cultural apparatus that historians refer to as the Lost Cause. The Lost Cause was a deliberate post-Civil War project, organized initially by Confederate veterans and their families and later institutionalized through the United Confederate Veterans, the United Daughters of the Confederacy, and aligned newspapers and publishing houses, to construct a memory of the war and Reconstruction that would justify the Confederate cause and discredit Reconstruction. The project succeeded substantially in shaping American public memory between roughly 1880 and 1960. David Blight’s “Race and Reunion” (2001) is the standard scholarly account of how the Lost Cause won the contest over national memory by emphasizing reconciliation between white Northerners and white Southerners while marginalizing the experience of formerly enslaved people and their descendants.

Grant’s reputation was a casualty of this larger memory contest. The Lost Cause needed the national enforcement of Reconstruction to read as tyrannical overreach rather than as a legitimate civil rights commitment; the figure of Grant, whose presidency had embodied that enforcement, had to be discredited to make the memory paradigm coherent. The drunken, corrupt, incompetent Grant of the popular caricature was a product of this memory work. He was less the Grant of contemporary documentation than the Grant required by the Lost Cause narrative to occupy the role of failed federal occupier.

The Lost Cause began to lose its grip on national memory during the rights era, but the decay was uneven. Confederate monuments installed between 1900 and 1925 remained in place through the 1960s and beyond. Textbook treatments of Reconstruction continued to use Dunning frameworks in many state systems through the 1970s. The 2015 Charleston church shooting accelerated public reexamination of Confederate iconography; the 2020 protests after the killing of George Floyd produced the largest wave of monument removals. The cultural apparatus that had constructed and maintained the Grant caricature dissolved publicly during this period, with the dissolution producing both backlash and acceleration.

The dissolution did not produce the historian rehabilitation; the historian rehabilitation had already moved substantially before the most visible public dissolution. But the two processes reinforced each other. As the Lost Cause’s cultural apparatus dissolved, the obstacle to general public acceptance of the post-Foner historian consensus dissolved with it. Chernow’s book, published in October 2017, reached a public that was substantially more prepared to read its argument than the same public would have been twenty years earlier. The 2017 Charlottesville violence, which had occurred in August before the book’s publication, had primed national attention to the Confederate-memorial question; Chernow’s narrative connecting Grant’s rights enforcement record to the larger Reconstruction story landed in a cultural moment ready to receive it.

This timing has been read by some critics as making the rehabilitation more cultural-political than scholarly. The criticism has merit at the level of timing and audience reception but does not survive examination of the scholarly trajectory itself. Foner had published in 1988, Stampp in 1965, Du Bois in 1935. The post-Dunning consensus on Reconstruction had been in place inside specialist scholarship for thirty years before the 2017 Charlottesville violence. What the cultural moment changed was the speed of diffusion from specialist scholarship to placement surveys and popular memory, not the underlying scholarly content. The diffusion would have happened anyway; the timing of its acceleration reflected the cultural moment.

The Historian Disagreement: Foner Against Chernow

The post-Foner consensus is not monolithic, and a substantive disagreement runs through the contemporary literature between historians who emphasize structural failure and those who emphasize presidential commitment. Naming this disagreement and adjudicating it is necessary for the verdict to mean anything. The shorthand is “Foner versus Chernow,” though the actual disagreement involves Blight, Calhoun, Brands, and several others, and the boundaries are not always clean.

Eric Foner’s position, developed across “Reconstruction” (1988) and subsequent essays, treats the Reconstruction-era failure as substantially overdetermined by structural forces that no presidential commitment could have overcome. White Southern violence, Northern Republican coalition erosion, the economic collapse of 1873, the limited administrative capacity of the nineteenth-century federal government, and the racial assumptions that even committed Reconstruction Republicans held all worked against the long-term success of the prosecution campaign. Within this analytical frame, the question of how much credit Ulysses Grant personally deserves becomes secondary to the question of how the structural forces operated. Grant gets credit for honorable commitment within the limits of what was politically possible; the failure is attributed primarily to the structural conditions rather than to presidential decision points.

Ron Chernow’s position, developed in “Grant” (2017), treats the personal commitment more heavily as an analytical variable. Within Chernow’s frame, the 1870-1872 enforcement peak demonstrates what was possible when presidential commitment aligned with prosecutorial capability and political coalition support; the subsequent failure tracks more closely with specific presidential decisions and political miscalculations rather than with abstract structural inevitability. Chernow gives more weight to what Ulysses Grant himself decided and less to what Northern Republican voters and the broader electoral configuration demanded. The frame produces a more rehabilitative reading because it credits Grant with substantive achievement during the years when his decisions were the binding constraint.

David Blight’s “Race and Reunion” (2001) operates at a different analytical level, focusing on the memory contest between white reconciliationist narratives and Black emancipationist narratives in the decades after the war. Blight’s analysis treats the Lost Cause’s victory in the memory contest as the substrate within which Reconstruction-era presidential reputations were subsequently constructed. The implication for Ulysses Grant’s rehabilitation is that the rehabilitation requires the memory contest to be partially relitigated; the rehabilitation of Reconstruction itself as a substantive historical project is the precondition for the rehabilitation of the president who tried to sustain it. Blight himself does not produce a Grant biography, but his framework provides the historiographic theory inside which the rehabilitation makes sense.

Charles Calhoun’s position sits closer to Chernow’s than to Foner’s on the rehabilitation question, but Calhoun emphasizes coalitional dynamics more than personal commitment. His framework reads the 1870-1872 enforcement as the product of a specific Republican coalition that included both committed Reconstruction Republicans and more skeptical Liberal Republicans whose continued support was contingent on the perception that enforcement could succeed. When the prosecution appeared to be producing diminishing returns by 1873 and 1874, the Liberal Republican wing peeled away, the coalition collapsed, and the remaining Republican commitment was insufficient to sustain the prosecution campaign at its earlier scale. The frame produces less explicit credit-assignment to Grant personally but more institutional understanding of why the prosecution campaign worked when it did and failed when it did.

How should the disagreement be adjudicated? The structural-versus-personal-commitment question is partly underdetermined by the available evidence. Some structural forces (the 1873 economic collapse, the demographic limits of the Republican coalition in the South) operated regardless of presidential decisions; some presidential decisions (the timing of the habeas corpus suspension, the choice of Akerman as Attorney General, the willingness to sign the 1875 Civil Rights Act in lame-duck status) clearly mattered for what was achieved within the structural constraints. The cleanest verdict is that both sides of the disagreement are partly correct: the structural forces set the outer envelope of what was possible, and presidential decisions determined how much of that envelope was actually filled. Foner is more right about why the enforcement ultimately failed; Chernow is more right about how much was achieved within the structural limits while it was succeeding.

The ranking implication of this adjudication is that the current placement around 17th-18th is approximately correct. A position closer to Chernow’s reading would push the placement higher, toward perhaps 14th or 15th; a position closer to Foner’s reading would push it slightly lower, toward perhaps 19th or 20th. The 17th-18th range corresponds to the analytical midpoint between the two readings. Future scholarship that systematically resolved the structural-versus-personal question in one direction or the other could produce a several-place ranking adjustment. The disagreement is unlikely to resolve quickly because the underlying question (how much credit to assign to presidential decisions within structural constraints) is a general analytical problem that recurs across presidential history rather than a Grant-specific question.

The Second-Term Collapse and Its Lessons

The 1872 reelection campaign produced an apparent vindication that masked the underlying coalitional erosion. Ulysses Grant won 56 percent of the popular vote against Horace Greeley, a Liberal Republican-Democratic fusion candidate whose campaign had been organized partly around opposition to the Reconstruction enforcement campaign. The electoral margin was substantial; Grant carried thirty-one states to Greeley’s six. The reelection appeared to ratify the enforcement campaign and to provide Grant with a renewed mandate for continued action. Within the next eighteen months, the apparent mandate had evaporated.

The Panic of September 1873, triggered by the failure of Jay Cooke and Company, produced the most severe economic depression in American history to that point. The depression continued through 1879 and reshaped Northern political priorities away from Reconstruction enforcement and toward economic recovery and government retrenchment. Federal budgets came under pressure that made sustained enforcement spending politically impossible. The 1874 midterm elections produced a Democratic House majority for the first time since the Civil War, eliminating the legislative coalition that had passed the Enforcement Acts. By 1875 the political configuration that had enabled the 1870-1872 enforcement peak had ceased to exist, and the federal capacity to act against organized political violence in the South had eroded substantially.

The 1875 Civil Rights Act was passed against this political backdrop. The legislation moved through Congress in the lame-duck session after the 1874 Democratic House victory, before the new House could be seated in March 1875. Republican congressional leaders including Benjamin Butler in the House and Senator Frederick Frelinghuysen guided the bill through the narrowing window of Republican legislative capability. President Ulysses Grant signed the bill on March 1, 1875. The political work required to get the bill through in those conditions was substantial; the contemporary congressional record documents Grant’s behind-the-scenes lobbying and the personal effort he expended securing votes from wavering Republicans. The act passed in a configuration where every additional commitment to civil-rights enforcement was a vote against the political tide.

The Whiskey Ring exposure in May 1875 came two months after the Civil Rights Act signing. Treasury Secretary Bristow had been pursuing the investigation for months with the president’s authorization; the public exposure produced a political crisis that consumed most of the administration’s remaining political capital. By December 1875 the Babcock connection had emerged, and Grant’s intervention in the prosecution destroyed what political coalition remained for further civil rights legislation. The 1876 election cycle moved attention to questions of administration purity and reform; the Reconstruction enforcement question became politically untouchable. The Compromise of 1877 that ended Reconstruction was not the cause of the enforcement collapse but the formal acknowledgment of a collapse that had already substantially occurred during 1873-1876.

The second-term trajectory is essential to the placement verdict because it documents both the failures and the limits within which Grant was operating. The failures were real: the Whiskey Ring intervention damaged the administration permanently, the political retreat from enforcement was not effectively resisted, and the institutional capacity that had been built up during 1870-1872 was largely dismantled. The structural limits were also real: no possible presidential decisions in 1874-1876 could have preserved the 1870-1872 enforcement scale, because the coalition that had supported that scale had ceased to exist. The current ranking around 17th-18th reflects a reasonable accounting of both the failures and the limits. A ranking that ignored the failures (placing Grant at 10th or higher) would understate the second-term collapse; a ranking that ignored the limits (placing Grant at 25th or lower) would understate what had been achieved during the brief period when it was politically possible.

The Complication: The Scandals Were Real

The rehabilitation is not exoneration. The scandals during Grant’s administration were real, were serious, and produced genuine damage to the federal government and to public confidence in republican institutions. Any honest verdict on Grant’s presidency has to give the scandals their full weight. The case for placing him at 17th rather than at 30th does not require denying what happened. It requires placing the scandals in proper analytic relation to the rest of the documentation.

Black Friday occurred on September 24, 1869, when the speculators Jay Gould and James Fisk attempted to corner the gold market through manipulation of federal Treasury policy. Their scheme required the Treasury to refrain from selling gold while they bought up the available supply; they sought to influence Treasury policy through Grant’s brother-in-law Abel Corbin, whose access to the president they hoped to convert into market intelligence. Grant himself appears in the documentary evidence as the man who broke the corner: when he understood what was happening, he ordered Treasury Secretary George Boutwell to sell government gold, breaking the speculators and ending the panic. The broader corruption was that Gould and Fisk had reached close to the president through familial ties; the partial vindication is that the president broke their corner when he understood the situation.

The Credit Mobilier scandal exposed in 1872 involved the construction company that had built the Union Pacific Railroad’s portion of the transcontinental line. The company had distributed shares of its stock to members of Congress at below-market prices in exchange for favorable legislative treatment. Vice President Schuyler Colfax was implicated, as was Vice-Presidential candidate Henry Wilson (who became Grant’s second-term vice president). The financial corruption itself had occurred before Grant became president; the scandal exposure occurred during his presidency. The damage to Grant’s administration was through association with his vice presidents rather than through his own actions, but the association was politically devastating during the 1872 campaign.

The Whiskey Ring exposed in 1875 was the most serious scandal in scale and the most damaging to Grant personally. The ring consisted of distillers, federal revenue agents, and Treasury officials in St. Louis, Milwaukee, and Chicago who had been defrauding the government of whiskey excise taxes for years; the total theft was estimated at over twelve million dollars in 1870s dollars (roughly equivalent to several hundred million in current dollars depending on conversion methodology). Treasury Secretary Benjamin Bristow’s investigation, conducted with Grant’s initial approval, produced over 350 indictments and over 100 convictions. The damage to Grant came in the investigation’s later stages, when it implicated his personal secretary Orville Babcock. Grant intervened in the prosecution to provide a deposition in Babcock’s defense, and Babcock was acquitted. The intervention damaged Grant’s reputation severely because it appeared to many contemporaries as protection of a corrupt subordinate, regardless of whether Grant himself had been personally complicit.

The Belknap scandal of 1876 involved Secretary of War William Belknap, who had taken kickbacks for the awarding of Indian trading post franchises. Belknap resigned in tears on the morning of his impeachment trial, attempting to escape the Senate’s jurisdiction; the Senate proceeded with the trial anyway and reached a majority for conviction that fell short of the required two-thirds for removal of an already-resigned official. The corruption was clear and the resignation under fire was clearly an attempt to evade accountability. Grant accepted the resignation, which subsequent historians have argued he should have refused in order to preserve the impeachment proceeding.

The Indian Ring scandals involved corruption at the Department of the Interior in the awarding of trading-post contracts to suppliers serving reservations. The corruption was systemic and Grant’s so-called Peace Policy with the tribes was substantially undermined by it. The Peace Policy itself, which sought to replace military administration of Indian affairs with religious-denominational administration under the theory that religious agents would be more honest than political appointees, produced mixed results; the religious agents were less corrupt than their predecessors on average but did not eliminate the corruption that the trading-post system enabled.

These scandals collectively form a serious indictment of administrative oversight. Grant’s pattern, visible across multiple cases, was misplaced personal loyalty to subordinates who had served him in the war or in his political rise. Babcock, Belknap, and others received Grant’s defense or his benefit of the doubt past the point where the documentary evidence supported the defense. This is a real failure of administrative judgment. It is also distinct from personal financial complicity, which the record does not support. The distinction matters for the placement question. A president who allows corruption through misplaced personal loyalty is a different category of failure from a president who is personally on the take. Grant belongs to the first category; the Dunning-era caricature had often implied or asserted membership in the second.

The verdict on the scandals shapes the placement ceiling. Grant cannot be ranked at 5th or 10th because the administrative failures were too serious and too sustained. The case for 17th-18th is that the rights record was a major substantive achievement that the Dunning paradigm had suppressed, and that the recalibration to include that record alongside the scandals produces a verdict in the upper-middle range. The case against 17th-18th is that the scandals were so damaging to federal institutional capacity that the ranking should be lower; this case is the one being made by historians who view the current consensus as having moved too far in the rehabilitative direction. The argument is open. The current consensus reflects where the weighting has settled as of 2024, not where it will permanently rest.

Verdict: Where Grant Belongs

The current ranking around 17th to 18th appears substantively correct based on the available evidence and reflects a reasonable weighting of the civil rights record against the scandals. The verdict could shift modestly in either direction as the next generation of scholarship works through specific questions. A rigorous scholarly examination of the Babcock relationship that produced harder evidence of presidential complicity in obstruction of the Whiskey Ring investigation could push Grant back to the low 20s. A more comprehensive reconstruction of the 1871-1872 enforcement campaign that documented additional substantive achievements could push him into the mid teens. Either move would be marginal rather than dramatic. The Foner-Brands-Chernow-Calhoun rehabilitation has effectively set the bounds of plausible ranking at roughly 15th to 22nd, with 17th sitting in the middle of that range.

The verdict that matters most is not the specific ranking number but the interpretive frame within which it is reached. The post-Foner frame treats Grant’s civil-rights enforcement as a major presidential achievement that has to be weighed against the administrative failures, with the weighting producing a mid-tier ranking rather than a bottom-tier one. This frame is now the consensus among Reconstruction specialists and is approaching consensus among generalist historians who participate in ranking polls. The frame is unlikely to reverse. A new generation of Lost Cause-aligned historiography is not visible on the academic horizon, and the scholarly infrastructure that would be required to reconstruct the Dunning paradigm has been dismantled.

The interpretive question that remains genuinely open is how to weight the failures of Grant’s second term against the achievements of his first. The 1870-1872 enforcement campaign was the most substantive period; the 1873-1876 period saw the collapse of the political coalition for enforcement, the worsening of the scandals, and Grant’s increasing isolation. Brands and Chernow tend to weight the first term more heavily; Foner and other Reconstruction specialists give somewhat more weight to the failures of the second term. The disagreement is honest and the evidence underdetermines a single answer. The ranking around 17th-18th sits roughly halfway between the more rehabilitative and the more critical positions. The specialist disagreement is unlikely to resolve in a way that produces dramatic future movement.

The cleanest answer to the ranking question is therefore: Grant’s current placement around 17th is substantively defensible, reflects a reasonable resolution of the scholarly disagreement, and is unlikely to move dramatically over the next generation. Future shifts will be marginal. The major reappraisal has happened.

Legacy: What the Grant Case Demonstrates

The Grant rehabilitation is the cleanest case study in twentieth-century American historiography of how presidential reputation is a downstream variable of academic regime. The Dunning frame produced one verdict; the Foner frame produces another; the underlying documentary evidence is substantially the same. This is not a claim that all historical interpretation is arbitrary; the post-Foner verdict is better supported by the documentary record than the Dunning verdict ever was, and the rehabilitation reflects evidence catching up to a more accurate reading of the same archives. But it is a claim that the dominant academic interpretation at any given moment substantially shapes what the documentary record is read to mean, and that presidential rankings track those dominant interpretations rather than tracking some fixed standard of presidential performance.

The implication extends to other presidential placement cases. The Truman rehabilitation from 22 percent approval at the end of his presidency to top-ten historian consensus is structurally similar: archive opening (the Soviet documents released after 1991), scholarly works (McCullough 1992, Hamby 1995, Miscamble 2002), and the diffusion of the new interpretation through ranking polls between 1995 and 2010. The Eisenhower reappraisal followed similar mechanics. The continuing failure of the Hoover rehabilitation provides the negative case: five rehabilitation attempts since the 1980s, none of which produced ranking movement, because the underlying record does not support the rehabilitation in the way that Grant’s record supported his.

The pattern is named by this article as the historiographic regime thesis: presidential rankings shift when the academic regime that interprets the underlying evidence shifts, and the magnitude of the shift is proportional to (1) how far the previous regime had distorted the underlying record and (2) how broadly the new regime’s interpretation diffuses through the historian community. Grant moves dramatically because the Dunning paradigm had distorted his record severely and the post-Foner paradigm restored a more accurate reading. Hoover does not move because no comparable distortion existed in his case; the original verdict on Hoover was substantially what the documentary record supports.

The house thesis of this series, that the modern presidency was forged in four crises and that emergency power created in those crises outlived the emergency, threads moderately through the Grant case. Grant’s October 17, 1871 peacetime habeas corpus suspension is a major early instance of emergency executive power deployed for civil rights ends. The deployment was successful in the narrow sense (it produced the prosecutions that broke the South Carolina Klan in 1872) and unsuccessful in the broader sense (the political coalition for sustained enforcement collapsed by 1874 and the gains were rolled back through the 1877 troop withdrawal under Hayes). The case illustrates one of the more underappreciated aspects of executive power history: not every emergency expansion was deployed for the conservative purposes that the imperial-presidency literature tends to emphasize. Grant’s expansion was deployed for civil rights, and its rollback was not a victory for civil liberties but a victory for the white supremacist forces the expansion had been deployed against. The history of executive power is more interpretively varied than a single thesis captures.

The Grant case also functions as the predecessor for civil rights enforcement, which would not be reattempted at comparable scale until Eisenhower sent the 101st Airborne to Little Rock in 1957. The eighty-year gap between Grant’s 1872 enforcement peak and the 1957 reactivation is the period during which Lost Cause memory work and Dunning School historiography produced the cultural and academic conditions under which civil rights enforcement were treated as illegitimate. The counterfactual question of what Reconstruction might have looked like if Lincoln had survived the assassination sits adjacent to the Grant question: the federal commitments that Grant attempted to sustain in 1870-1872 were undertaken in the political space left by Lincoln’s death and Andrew Johnson’s failure. Grant inherited the Reconstruction question in the worst possible political configuration and produced more substantial enforcement than the inheritance had positioned him to deliver. The rehabilitation has been able to credit that achievement because the academic regime now reads the documentary record without the Dunning frame’s distortions. Future regime shifts may produce further movement in either direction, but the major reappraisal has been completed and the verdict has settled near 17th. That verdict is closer to the documentary record than any previous verdict has been. The case is closed for the foreseeable future, not because the truth has been fully recovered, but because the regime change that produced the recovery has run its course.

Frequently Asked Questions

Q: What was Ulysses Grant’s lowest historian ranking?

Grant’s lowest documented ranking in a major historian poll was 33rd of 41 in the C-SPAN survey released in February 2000. The C-SPAN result represented a brief reversal from earlier polls (Schlesinger 1948 placed him 28th of 29, Murray-Blessing 1982 placed him 28th of 36, Schlesinger Jr. 1996 placed him 29th); the 2000 dip appears to have reflected sampling differences in the C-SPAN panel rather than new scholarly content. By the C-SPAN 2009 survey Grant had climbed to 23rd, reflecting the delayed diffusion of post-Foner Reconstruction scholarship through the historian community. The trajectory since 2009 has been steadily upward, reaching 17th in the 2024 Presidential Greatness Project survey.

Q: Why did historians rank Grant so low for so long?

The low ranking through roughly 1990 reflected the dominance of the Dunning School interpretation of Reconstruction, which treated federal rights protections as overreach and Grant’s signature policies as failures rather than achievements. Within the Dunning frame, Grant’s Enforcement Acts, his Klan prosecutions, and his 1875 Civil Rights Act looked like misguided Northern aggressions. The frame also amplified the importance of the scandals (Whiskey Ring, Credit Mobilier, Belknap) relative to other aspects of the record. When the Foner-era scholarship dismantled the Dunning frame, the basis for the low ranking dissolved. The lag between scholarly reframing (1988 Foner) and ranking poll response (2009 C-SPAN onward) reflects the diffusion time required for new interpretations to reach historians outside the Reconstruction specialty.

Q: Who wrote the most influential book in rehabilitating Grant?

Ron Chernow’s 2017 biography “Grant” had the largest popular impact and was the proximate cause of the 2024 ranking jump. But the scholarly groundwork was laid earlier and elsewhere. Eric Foner’s “Reconstruction: America’s Unfinished Revolution” (1988) established the interpretive frame within which Grant’s record could be reread. H.W. Brands’s “The Man Who Saved the Union” (2012) provided the first major popular biography to incorporate the post-Foner scholarship. Charles Calhoun’s “The Presidency of Ulysses S. Grant” (2017) provided the rigorous scholarly foundation that anchored the rehabilitation. The combined effect of these four works, with each playing a different role, produced the reappraisal. Naming a single most influential book is misleading; the rehabilitation was a multi-author intellectual project.

Q: Were Grant’s scandals worse than other presidential administrations?

The Grant administration scandals were serious in scope and damaging to federal institutional capacity, but a comparative assessment places them in the upper range of nineteenth-century presidential administrations rather than uniquely catastrophic. The Warren Harding administration’s Teapot Dome scandal (1922) involved direct cabinet-level criminal corruption (Interior Secretary Albert Fall accepted bribes from oil companies and was later convicted) that some historians treat as comparable in seriousness to the Belknap case. The Andrew Johnson administration produced less corruption but more institutional damage through impeachment. Twentieth-century scandals (Watergate, Iran-Contra) involve different categories of executive abuse rather than personal-enrichment corruption. Grant’s scandals were severe enough to weigh substantially in any ranking but not so unique as to require placement at the bottom of presidential rankings; the Dunning-era treatment exaggerated the scandals’ uniqueness as part of the larger interpretive frame.

Q: How many people did Grant prosecute for Klan activity?

Federal authorities under Grant’s administration produced over 3,000 indictments and over 600 convictions in Klan-related prosecutions during 1871 and 1872, with the peak activity occurring in the South Carolina counties where habeas corpus had been suspended in October 1871. The numbers come from Department of Justice records and contemporaneous reports of federal district attorneys. The prosecutions effectively broke the South Carolina Klan in those counties; the broader Klan was substantially weakened in other Southern states as well, though regional variations in enforcement intensity produced uneven results. The Akerman-led prosecution campaign was the most substantial federal action against domestic terrorism in the nineteenth century and had no comparable equivalent until the FBI’s 1960s civil rights prosecutions.

Q: What is the Dunning School and why does it matter for Grant?

The Dunning School refers to the interpretation of Reconstruction developed by William Archibald Dunning and his graduate students at Columbia University in the early twentieth century. The school produced state-by-state Reconstruction histories that interpreted federal enforcement as overreach, treated Reconstruction governments as corrupt or incompetent, and viewed white Democratic redemption as legitimate restoration of self-government. The frame dominated academic and popular treatments of Reconstruction from roughly 1907 through the 1960s. Within the Dunning frame, Grant’s rights enforcement looked like misguided federal aggression rather than substantive achievement, which depressed his presidential ranking by approximately fifteen places. The Dunning School’s collapse between 1965 (Stampp) and 1988 (Foner) dismantled the interpretive basis for the low ranking and enabled the subsequent rehabilitation.

Q: Why did W.E.B. Du Bois’s 1935 book on Black Reconstruction not move the consensus?

Du Bois’s “Black Reconstruction in America” published in 1935 provided a comprehensive scholarly refutation of the Dunning School, including a substantial defense of Grant’s civil rights enforcement, but failed to move the white-dominated academic historical establishment of its time. The reasons included pervasive racism in 1930s academia that marginalized Black scholars, Du Bois’s Marxist analytical frame that political conservatives could dismiss as ideological, and the absence of institutional infrastructure (graduate students, dissertation pipelines, journal access) that would have allowed his interpretation to propagate through the white academic community. The book remained influential within Black scholarship and at historically Black colleges but did not reshape the broader consensus until Kenneth Stampp at Berkeley adopted substantially similar interpretive positions in 1965. The thirty-year lag illustrates how academic regime change is structured by who can credibly make arguments inside the institutional academy.

Q: What was the 1875 Civil Rights Act and what happened to it?

The Civil Rights Act of March 1, 1875 prohibited racial discrimination in public accommodations including hotels, theaters, and public conveyances, and represented the last major federal civil rights legislation between Reconstruction and the 1957 Civil Rights Act. Grant signed the bill during his lame-duck period with full knowledge that the incoming political configuration would not support similar legislation. The Supreme Court struck down the public accommodations provisions in the Civil Rights Cases of 1883 by 8-1 (Justice John Marshall Harlan dissenting), holding that the Fourteenth Amendment authorized federal regulation of state action but not of private discrimination. The Court’s decision effectively eliminated federal civil rights enforcement in public accommodations for eight decades until the 1964 Civil Rights Act revived comparable provisions on a different constitutional foundation (the Commerce Clause).

Q: Was Grant actually drunk while serving as president?

The historical record does not support claims that Grant was drunk while serving as president. Grant did drink heavily at documented moments during his pre-war career in the 1850s, and the drinking contributed to his 1854 resignation from the Army. He drank moderately during the Civil War, with periodic incidents during periods of low command activity but never during major military operations. As president, no contemporaneous source (cabinet members, White House physician, political opponents in Congress) documented drunken episodes. The drunk-president story congealed in retrospective memoir literature and was repeated as established fact by writers who had not examined the contemporary record. Chernow’s 2017 biography reviews the drinking question in detail and concludes that the picture of a drunken president has no contemporary documentary foundation, though Grant continued to wrestle with drinking as a personal issue throughout his life.

Q: How does Grant’s ranking compare to other consensus-flip presidents?

Grant’s rehabilitation is the largest documented in twentieth-century historian polling, moving approximately fifteen places from his lowest verified placement to his 2024 position. Harry Truman moved from a 22 percent end-of-presidency approval rating to top-ten historian consensus, a substantial rehabilitation but one that involved less ranking-poll movement because Truman had not been ranked as low as Grant initially. Dwight Eisenhower rose from approximately 22nd in 1962 polls to consistent top-ten placement in twenty-first-century surveys. The Calvin Coolidge rehabilitation has produced more modest movement, and the Herbert Hoover rehabilitation has produced essentially no movement despite five separate biographical efforts since the 1980s. The variation in rehabilitation outcomes reflects differences in how much the original verdict had been distorted by the academic regime of its time versus how much the original verdict accurately reflected the documentary record.

Q: Who was Amos Akerman and why does he matter for the Grant story?

Amos Akerman served as United States Attorney General from June 1870 to December 1871 and led the federal prosecution campaign against the Ku Klux Klan during its most intensive period. Akerman was a Georgia Republican who had briefly served in the Confederate Army before becoming a Reconstruction Republican; his commitment to enforcement was personal and unyielding. Working with the newly established Department of Justice (created June 1870), Akerman directed the prosecution that produced the bulk of the 3,000-plus indictments and 600-plus convictions in Klan-related cases. He was forced out of office in December 1871 under pressure from railroad interests who opposed his refusal to favor their litigation positions; his removal weakened but did not immediately end the enforcement campaign. Akerman’s tenure is a critical archive for the Grant rehabilitation because his prosecutorial work documents the substantive scale of the federal civil rights effort that the Dunning frame had been organized to suppress.

Q: Did Grant know about the corruption in his administration?

The documentary record shows Grant having varied knowledge across different scandals. He did not know about Credit Mobilier until the 1872 exposure, since the corruption had occurred before he became president. He learned about the Whiskey Ring through Treasury Secretary Bristow’s investigation and initially approved the investigation; his subsequent intervention to defend personal secretary Orville Babcock damaged his reputation severely but is best understood as misplaced personal loyalty rather than direct complicity in the underlying theft. The Belknap kickbacks at the War Department were not known to Grant until the impeachment proceedings began, at which point he accepted Belknap’s resignation. The Black Friday gold speculation reached close to him through familial ties (his brother-in-law Abel Corbin), but when Grant understood the situation he ordered Treasury action that broke the corner. The pattern is one of credulity about specific subordinates and family members rather than personal financial complicity; the distinction matters for assessing the scandals’ weight against the policy record.

Q: What books should I read to understand the Grant rehabilitation?

The four essential books, in roughly the order one should read them, are: Eric Foner’s “Reconstruction: America’s Unfinished Revolution” (1988) for the interpretive frame; H.W. Brands’s “The Man Who Saved the Union: Ulysses Grant in War and Peace” (2012) for the popular biography that translated the new frame to general readers; Ron Chernow’s “Grant” (2017) for the comprehensive narrative biography that drove the 2024 ranking shift; and Charles Calhoun’s “The Presidency of Ulysses S. Grant” (2017) for the rigorous scholarly foundation. Earlier important works that influenced the rehabilitation include Kenneth Stampp’s “The Era of Reconstruction” (1965), John Hope Franklin’s “Reconstruction After the Civil War” (1961), W.E.B. Du Bois’s “Black Reconstruction in America” (1935), and David Blight’s “Race and Reunion” (2001) for understanding the Lost Cause apparatus that had originally depressed Grant’s reputation.

Q: What are presidential ranking surveys and which ones matter most?

The major modern presidential ranking surveys include the C-SPAN Presidential Historians Survey (conducted 2000, 2009, 2017, 2021), the Siena College Research Institute polls (conducted multiple times since 1982), the Presidential Greatness Project Expert Survey (Rottinghaus and Vaughn, conducted 2014, 2018, 2024), and various American Political Science Association-affiliated panels. These surveys vary in methodology, panel composition, and rating dimensions, but they tend to produce broadly consistent results with individual presidents moving across a range of 5-10 places between surveys. Historians who participate in multiple surveys often rate consistently across them, which means survey-to-survey variation reflects panel composition more than methodology differences. For tracking the Grant rehabilitation, the C-SPAN and Siena results provide the longest comparable time series; the Presidential Greatness Project surveys have provided the most recent movement (2024 result of 17th).

Q: Did the Lost Cause hurt other presidents’ reputations besides Grant?

Yes, though Grant was the most affected because his administration most directly embodied federal civil rights enforcement. Andrew Johnson received complicated treatment in Lost Cause historiography because his obstruction of Reconstruction aligned with Lost Cause political preferences but his impeachment and his pre-Reconstruction Unionism complicated the alignment; Johnson’s ranking has remained low for separate reasons related to his obstructionism and racism. Lincoln’s reputation was paradoxically protected by Lost Cause memory work that emphasized his April 1865 reconciliation rhetoric over his earlier emancipation actions, allowing white Southerners to claim a moderate Lincoln in opposition to Reconstruction Republicans. Rutherford Hayes, who ended Reconstruction in 1877, has received mixed treatment because his role in ending federal enforcement fit Lost Cause preferences while his Civil War service complicated them. The historiographic regime that produced the Lost Cause-era distortions affected multiple presidential rankings; Grant’s rehabilitation is one element of a broader Reconstruction-era reappraisal that is still working through the historian community.

Q: What is the relationship between Grant’s military reputation and his presidential reputation?

Grant’s military reputation was protected from the Dunning-era depression of his presidential reputation because American military reputation operates substantially independently of political reputation. The same Grant whose presidency was treated as failure was almost universally treated as a great general; the Wilderness Campaign, Vicksburg, and Appomattox were not subject to the same interpretive frame that depressed his civil rights enforcement record. This bifurcation produced the standard Dunning-era characterization of Grant as a great general who failed in the White House. The rehabilitation has substantially closed the gap between military and presidential reputation, with the post-Foner frame treating Grant’s presidency as a continuation of the same character traits (persistence, refusal to be panicked by setbacks, willingness to use force against organized opposition) that had produced his military success. The closing of the gap reflects the dismantling of the artificial separation between his battlefield and political records.

Q: Why did Grant suspend habeas corpus in 1871?

Grant’s October 17, 1871 proclamation suspended the writ of habeas corpus in nine South Carolina counties under the authority granted by the Third Enforcement Act (Ku Klux Klan Act) of April 1871. The suspension allowed federal marshals to arrest suspected Klansmen without prior indictment in the up-country counties where Klan terror had been most severe. Attorney General Akerman had presented Grant with evidence of organized political violence including documented killings of federal officials and Republican voters; the suspension was the legal mechanism that enabled the prosecution campaign producing over 3,000 indictments and 600 convictions in 1871-1872. This was the only peacetime suspension of habeas corpus in the nineteenth century and represents one of the most significant peacetime exercises of emergency executive power in American history. The post-Foner historiography treats the suspension as a defensible response to organized domestic terrorism; earlier Dunning-frame treatments had treated it as dictatorial overreach.

Q: How long did the Grant rehabilitation take?

The full rehabilitation, from the first scholarly challenges to the Dunning frame to the 2024 ranking results, took approximately ninety years (1935 Du Bois to 2024 Presidential Greatness Project). The ranking-poll response, however, took only about twenty years from its acceleration point: C-SPAN 2000 result of 33rd to 2024 Presidential Greatness Project result of 17th. The gap between scholarly reframing (which was substantially complete with Foner 1988) and ranking response (which began moving significantly in 2009) reflects the diffusion lag between specialist scholarship and the broader historian community that participates in ranking surveys. The pattern is consistent across other consensus-flip cases: the scholarly turn precedes the ranking response by 15-25 years, with the lag determined by how broadly the new scholarship circulates outside the specialty community and how widely it is taught in graduate programs.

Q: Could Grant’s ranking fall again?

A future ranking reversal is theoretically possible but unlikely on visible academic horizons. A reversal would require either substantial new evidence of Grant’s personal complicity in scandals (which would weaken the rehabilitation but not eliminate the civil rights record’s positive weight), or a new academic regime that downgrades civil rights achievement as a ranking criterion (which would require political and intellectual shifts not currently in evidence), or a major reinterpretation of Reconstruction that restored some version of the Dunning frame (which would require the dismantling of the Foner-era consensus, again not currently visible). The more plausible future trajectory is stabilization around the current 17-20 range with modest fluctuation. The major reappraisal has happened; future movement will be marginal rather than dramatic.

Q: What is the historiographic regime thesis?

The historiographic regime thesis, advanced in this article, holds that presidential rankings shift when the academic regime that interprets the underlying evidence shifts, and that the magnitude of the shift is proportional to (1) how far the previous regime had distorted the underlying record and (2) how broadly the new regime’s interpretation diffuses through the historian community. Grant’s case is the cleanest demonstration: the Dunning frame had distorted the civil rights record severely, the post-Foner frame restored a more accurate reading, and the ranking moved approximately fifteen places to reflect the changed interpretation. The thesis is testable against other consensus-flip cases (Truman, Eisenhower) and against cases where rehabilitation has failed (Hoover, Harding). It predicts that future ranking shifts will be largest where current verdicts diverge most from what the documentary record best supports, and smallest where current verdicts already reflect a defensible reading of the available evidence.

Q: How did Grant’s Memoirs influence later historians?

Grant’s two-volume Personal Memoirs, completed days before his death in July 1885 and published by Mark Twain’s firm later that year, became the most consequential primary source in shaping later assessments of his life. The Memoirs sold over 300,000 copies in their first year and remained continuously in print into the twenty-first century, providing readers direct access to Grant’s own narration of his career through 1865. Twain, Edmund Wilson, and Gertrude Stein recognized the prose quality; modern historians from Brands to Chernow drew heavily on the Memoirs to recover the persistent and methodical Grant whose strategic thinking the Dunning-era caricature had obscured. The Memoirs’ largest limitation for the rehabilitation is that Grant stopped the narrative at Appomattox and never produced a companion volume covering his presidency. The presidential years had to be reconstructed from cabinet papers, congressional records, and the Library of Congress Grant Papers rather than from Grant’s own retrospective account, which meant the rehabilitation depended on archival recovery work that the military reputation had not required.

Q: What is the connection between the Grant rehabilitation and modern civil rights history?

The Grant rehabilitation closely tracks the broader recovery of nineteenth-century federal civil rights history that the Lost Cause apparatus and Dunning School had suppressed. As historians like David Blight, Eric Foner, and Heather Cox Richardson reconstructed the substantive scope of Reconstruction enforcement, the achievements that the post-1877 reaction had erased reentered the historical narrative. Grant’s prosecution campaign against the Klan, the 1875 Civil Rights Act, the operation of the Department of Justice under Akerman, and the Enforcement Acts’ coverage of voting rights protections all became visible again as substantive federal commitments rather than failed overreach. The connection to modern civil rights history runs in both directions: the modern movement provided the political and intellectual context within which the Reconstruction-era achievements could be appreciated, and the recovery of those achievements provided historical depth for the modern movement’s claims that federal civil rights enforcement had a substantive nineteenth-century predecessor. The Grant rehabilitation is one element of a larger reckoning with what the post-1877 reaction had cost the country and what its recovery has required.
