On the morning of April 11, 1898, a clerk read aloud to a packed House chamber a message from the president of the United States. The man who composed that message had spent two months trying to avoid the very thing the message requested. Two days earlier, on April 9, the Spanish government in Madrid had agreed to nearly every demand the American minister had laid before it: immediate armistice in Cuba, an end to the reconcentration policy, the conversion of the Cuban question into a matter for arbitration on terms favorable to the United States. The cable carrying that news had reached the State Department on April 10. The president read it. He attached a single, almost grudging sentence to the war message acknowledging the Spanish concession. And then he sent the message to Congress anyway, asking for authority to use the army and navy of the United States to compel a settlement Spain had already offered without compulsion.

How does a chief executive who does not want a war get one? The question is not rhetorical. William McKinley was a Civil War veteran who had seen Antietam at twenty-one, a methodical lawyer-politician who had run twice for the presidency on tariff and monetary issues with virtually no foreign-policy content, and a man whose private letters from February through early April 1898 record exhausting attempts to keep the peace through diplomacy in Madrid. The standard textbook narrative compresses this into a sentence: yellow journalism and the explosion of the Maine pushed an irresolute president into a popular war. The actual record, recoverable from the McKinley-Woodford correspondence in the State Department archives, the cabinet minutes preserved by John Hay’s later editors, the diaries of Henry Cabot Lodge and Theodore Roosevelt, and the Spanish foreign-ministry papers excavated by John Offner and others, is harder. McKinley’s reluctance was real. The diplomatic track was succeeding. And the war came anyway, brought by structural forces that operated independently of presidential will.

This article reconstructs the February-through-April 1898 decision arc as a study in how the modern American war power actually works. The reconstruction yields a specific argument and a specific artifact. The argument is what we will call the McKinley paradox: a reluctant executive can be the wrong place to look for the causes of an executive-driven war, because the structural pressures that produce modern wars operate through congressional majorities, organized press campaigns, party-electoral calculation, and bureaucratic action by subordinates (in this case Theodore Roosevelt at the Navy Department), rendering the president’s private preferences increasingly irrelevant as the structural ratchet tightens. The artifact is a parallel-track timeline showing diplomatic progress in Madrid on one column and congressional war-pressure escalation in Washington on the other from February 15 through April 11, 1898, documenting that the diplomatic track was winning at the moment the political track foreclosed it. The article also threads what we will call, throughout the InsightCrunch presidents series, the imperial-presidency thesis: that executive power expanded by emergency or war is rarely surrendered after the emergency ends, and that the foreign-policy template established under McKinley between April 1898 and December 1898 is the template from which Theodore Roosevelt, Woodrow Wilson, Franklin Roosevelt, Harry Truman, Lyndon Johnson, and George W. Bush all subsequently worked.

The Setup: Cuba, the Yellow Press, and a Dovish Republican in 1897

To understand how the April 1898 message happened, one needs the situation McKinley inherited on March 4, 1897, and the trajectory of that situation across the thirteen months between inauguration and the Maine.

Cuba had been in revolt against Spanish rule since February 24, 1895, when the cry of Baire reignited a struggle that the Ten Years War of 1868 through 1878 had failed to settle. Jose Marti, the writer-organizer who had built the Cuban Revolutionary Party in exile in the United States, died at Dos Rios on May 19, 1895, six weeks into the new rebellion, leaving the political leadership to Tomas Estrada Palma in New York and the military leadership to Maximo Gomez and Antonio Maceo in the field. The rebels controlled the countryside; Spanish forces under Captain-General Arsenio Martinez Campos held the cities and the railroad lines and could not pacify the interior. When Madrid replaced Martinez Campos in February 1896 with General Valeriano Weyler y Nicolau, the conflict turned ugly in a specific institutional way.

Weyler’s reconcentration policy, ordered on October 21, 1896, required Cuban civilians in the western and central provinces to relocate within Spanish military lines within an eight-day deadline. The military rationale was sound on its own terms: deny the rebel forces the rural population that supplied them, and the rebels would starve. The humanitarian consequence was a catastrophe. Civilians driven into hastily built camps around Havana, Matanzas, Pinar del Rio, and Santa Clara died of disease and hunger at rates whose specific numbers are disputed by historians (the Cuban historian Jorge Ibarra’s figures and the contemporary American consular reports diverge) but whose order of magnitude is not: somewhere between 100,000 and 300,000 Cuban civilians died in the reconcentration camps between late 1896 and 1898. The American press, particularly the New York Journal under William Randolph Hearst and the New York World under Joseph Pulitzer, covered the camps with photographs and atrocity reportage that varied from scrupulously documented to fabricated; what mattered for the eventual war pressure was that the public read about Cuban suffering daily and that the suffering was, in its essentials, real.

Grover Cleveland, in the final two years of his second term, had treated the rebellion as a foreign quarrel in which the United States had no business. His December 7, 1896 annual message acknowledged American sympathy for Cuban suffering while explicitly refusing to recognize Cuban belligerency or independence and ruling out armed intervention. Cleveland was a Bourbon Democrat with a strict-constructionist view of the federal government and an old-school Jeffersonian skepticism of foreign entanglement; he believed the constitutional war power was a check, not a license, and he intended to leave the Cuban question to his successor exactly as he had found it. The successor was William McKinley, who took the oath on March 4, 1897.

McKinley arrived in office with a temperament forged in two formative environments. The first was the Twenty-third Ohio Volunteer Infantry, in which he served from June 11, 1861, through July 26, 1865, rising from private to brevet major and emerging from Antietam and Cedar Creek with the conviction, which he repeated in private throughout his career, that he had seen too much killing on those fields to want to see more from a position of national authority. The second was the Stark County, Ohio, congressional district he represented in the House from 1877 through 1891 (with one short interruption), where he became the leading congressional voice for protective tariffs and gold-standard finance and where he formed the political partnership with the Cleveland industrialist Mark Hanna that carried him to the governorship of Ohio in 1892 and to the presidency in 1896. Hanna ran the 1896 campaign on monetary politics: gold versus William Jennings Bryan’s silver, with the tariff as the secondary frame. Foreign policy barely appeared in the platform. McKinley’s inaugural address devoted exactly one paragraph to international relations, urging arbitration and warning against any war of conquest.

Lewis Gould, in his standard biography The Presidency of William McKinley, emphasizes that the president’s foreign-policy instincts in 1897 were genuinely cautious; the man was not pretending to dislike war for political cover. John Offner, whose An Unwanted War remains the most thorough archival reconstruction of the diplomacy on both sides of the Atlantic, documents that McKinley spent the spring and summer of 1897 trying to find a diplomatic settlement that would end the Cuban suffering without American intervention. The vehicles were two: pressure on Madrid to grant autonomy to Cuba (a status short of independence under which Cuba would have internal self-government within the Spanish empire), and humanitarian relief funneled through the American Red Cross under Clara Barton.

The Madrid pressure track produced its first concrete success in October 1897. Antonio Canovas del Castillo, the conservative Spanish prime minister who had supported Weyler’s policy, was assassinated by an Italian anarchist on August 8. His successor, the liberal Praxedes Mateo Sagasta, came to power on October 4 committed to a different Cuban policy. Sagasta recalled Weyler on October 9 and replaced him with General Ramon Blanco y Erenas, who began winding down the reconcentration policy in November. On November 25, 1897, Sagasta’s government announced an autonomy decree granting Cuba a parliament with control over internal affairs, customs, and budget, with foreign affairs and military matters retained by Madrid. The decree took effect on January 1, 1898. From an American diplomatic perspective, this was substantial progress: the policy that had produced the worst civilian suffering had been reversed, and a political framework short of independence but well beyond colonial rule had been offered.

The autonomy framework, however, satisfied neither the Cuban insurgents, who refused to negotiate on any terms short of full independence, nor the Spanish colonial population in Havana, who saw autonomy as the prelude to abandonment by Madrid. On January 12, 1898, Spanish loyalist officers in Havana rioted against autonomist newspapers, ransacking the offices of La Discusion and El Reconcentrado. The Havana riots alarmed the American consul general, Fitzhugh Lee (the former Confederate cavalry general and nephew of Robert E. Lee), who cabled Washington requesting a warship in Havana harbor for the protection of American citizens and property. McKinley’s State Department, under Secretary John Sherman until February and then under Acting Secretary William R. Day after Sherman’s effective retirement, hesitated. The Spanish government had not formally requested American protection, and dispatching a warship without invitation would be diplomatically provocative. After delicate exchanges in which Madrid grudgingly acquiesced to the visit as a friendly call, the second-class battleship USS Maine, under Captain Charles Sigsbee, entered Havana harbor on the morning of January 25, 1898.

What pushed McKinley closer to confrontation in the first six weeks of 1898 was not the riots, which subsided, but the publication on February 9 of a private letter written by Enrique Dupuy de Lome, the Spanish minister in Washington, to his friend Jose Canalejas, a Spanish journalist visiting Havana. The letter had been stolen by a Cuban sympathizer in the Havana post office and forwarded to the Cuban Revolutionary Party in New York, which provided it to Hearst’s Journal. Translated into English, the relevant passages described McKinley as “weak and a bidder for the admiration of the crowd, besides being a would-be politician who tries to leave a door open behind himself while keeping on good terms with the jingoes of his party.” The published letter exploded in Washington. Dupuy de Lome resigned by cable before he could be expelled. The Spanish government formally apologized and disavowed the language on February 14. The substantive damage to negotiations, however, was already done: the American president had been called a weak political hack by the senior Spanish diplomat in Washington, and although McKinley’s public response was measured, his willingness to extend diplomatic concessions to Madrid contracted after February 9.

Then, six days later, the Maine exploded.

The Core Argument: Two Parallel Tracks, February 15 Through April 11, 1898

The decision arc that produced the April 11 war message ran along two tracks that operated almost independently of each other. The diplomatic track ran from Washington to Madrid through Stewart Lyndon Woodford, the former Union general and New York Republican lawyer whom McKinley had appointed minister to Spain in June 1897 with explicit instructions to seek a diplomatic resolution of the Cuban question. The political track ran from the Senate floor and the front pages of the New York newspapers to a presidential desk increasingly hemmed in by congressional resolutions, party-electoral pressure, and the slow accumulation of public anger that the Maine, the Proctor speech of March 17, and the Court of Inquiry report of March 28 produced in sequence. The two tracks moved in opposite directions across February and March. By April 9, the diplomatic track had effectively won. By April 11, the political track had foreclosed the diplomatic victory. The simultaneity is the substance of the decision.

The Maine: February 15, 1898

The USS Maine had been anchored in Havana harbor for three weeks when, at 9:40 in the evening of February 15, 1898, an explosion tore through her forward magazines, killing 261 of the 355 officers and men aboard and sinking the ship in the shallow harbor. Captain Sigsbee survived. His first cable to Washington, sent within hours of the explosion, contained a sentence that has been remembered for the discipline it required of a commander whose ship had just been destroyed beneath him: “Public opinion should be suspended until further report.” Sigsbee himself did not know what had caused the blast. He suspected an external mine but acknowledged that internal causes could not be ruled out.

The American naval Court of Inquiry that the Navy Department convened under Captain William T. Sampson sat in Havana from February 21 through March 21, 1898, taking testimony from divers who examined the wreck and from surviving crew members. Its report, signed on March 21 and transmitted to Washington on March 28, concluded that the destruction of the Maine had been caused by the detonation of a submarine mine that had in turn ignited two or more of the ship’s forward magazines. The court did not assign responsibility to any person or government, noting that the available evidence did not permit identification of who had placed or detonated the mine. The Spanish Court of Inquiry that sat in parallel reached the opposite conclusion: an internal explosion, probably in the forward coal bunker adjacent to the six-inch reserve magazine, in which spontaneous combustion of bituminous coal had ignited the magazine through the bulkhead.

The modern forensic verdict tilts toward the Spanish finding. The 1976 investigation conducted by Admiral Hyman Rickover and a team of naval engineers concluded that the most probable cause was a coal-bunker fire that ignited the magazine; the 2002 Naval History and Heritage Command review reached the same conclusion with greater certainty given the metallurgical and structural evidence from the wreck recovered between the 1898 inquiry and the eventual scuttling of the salvaged hull in 1912. The contemporary American Court of Inquiry, working with the diving technology and explosive metallurgy available in 1898, almost certainly got it wrong.

What matters for the McKinley decision arc, however, is not the metallurgical truth of February 15 but the political fact of late March. The American public, the American press, and most of the American Senate by April 1898 believed that Spain had blown up the Maine, either through an official act of state or through tolerance of saboteurs that amounted to complicity. The slogan that Hearst’s Journal popularized within days of the explosion - “Remember the Maine, to hell with Spain” - was not a research conclusion; it was a political force that operated regardless of whether the underlying claim was true.

McKinley’s response to the explosion in the four days between February 15 and February 19 was characteristic: silence in public, urgent diplomacy in private. He cabled Woodford in Madrid to convey to the Spanish government the absolute necessity of cooperation with the American inquiry and to make clear that the president would suspend judgment until the formal report. He sat with Mark Hanna and with Vice President Garret Hobart at the White House and walked through the political calculus of holding the war pressure off. He met with the Senate Foreign Relations Committee on February 25 to brief them on the diplomatic posture. The Hearst and Pulitzer presses raged. McKinley waited.

The Proctor Speech: March 17, 1898

The hinge between the Maine explosion and the war message was a Senate speech delivered on March 17, 1898, by Redfield Proctor, the former governor of Vermont, founder of the Vermont Marble Company, and Republican senator. Proctor was no jingo. He was, by reputation, the dryest and most fact-oriented member of the Senate Republican caucus. He had spent two and a half weeks in Cuba in February and early March, traveling the western provinces and inspecting the reconcentration camps personally, with no announced intention of producing a war speech and with no formal commission from the administration. When he returned to Washington he requested the floor on March 17 to report what he had seen.

The speech that resulted, reproduced in the Congressional Record for that date and circulated as a pamphlet within days, did three things that no prior public statement on Cuba had done. It described the reconcentration camps in the factual, statistical register of a businessman describing an industrial inventory: numbers, dimensions, conditions, mortality rates, with names of villages and provinces. It declined to make any case for war and explicitly disclaimed any prior commitment to intervention. And it concluded with the observation that what the senator had seen in Cuba was not a colonial war but a humanitarian catastrophe of a specific, measurable, and largely man-made kind, and that the question of what the United States ought to do about it was now before the Senate as a matter of fact rather than rhetoric. The speech ran roughly 9,800 words. It was, by every contemporary account from senators to journalists to McKinley himself, the moment after which the war became politically inevitable.

Henry Cabot Lodge, Theodore Roosevelt, William Allen White, John Bassett Moore, and a half-dozen other contemporaries left written observations to the effect that Proctor’s speech turned the previously interventionist case from a matter of yellow-press passion into a matter of sober factual record. The conversion of the conservative Republican business wing of the party, which had previously aligned with McKinley’s diplomatic caution against the intervention pressure from Lodge, Roosevelt, and the imperialist wing, was the political event of March 1898. With Proctor’s speech, the business case for restraint dissolved, because the conservative business senator had himself returned from Cuba prepared to vote for intervention if no other remedy could be found.

McKinley read the speech. His subsequent cables to Woodford, recovered from the State Department files and reprinted in the Foreign Relations of the United States volumes for 1898, show that on March 17 and the days immediately following, he intensified the diplomatic ultimatum to Madrid. The new pressure was not the Maine; the Maine was nearly five weeks old by Proctor’s speech. The new pressure was that the political coalition that had held the intervention line was breaking, and McKinley knew that if he did not extract a sufficient diplomatic concession from Madrid within weeks, Congress would force his hand.

The March 27 Ultimatum

On March 27, 1898, McKinley dispatched through Acting Secretary Day a cable to Woodford in Madrid setting out the terms on which the United States would refrain from intervention. The cable, the precise text of which appears in the State Department archives and in Margaret Leech’s In the Days of McKinley, demanded three specific items: an armistice in Cuba until October 1, 1898; the immediate revocation of the reconcentration order, with relief for the camp populations; and a commitment by Spain that if no settlement between Madrid and the Cuban insurgents had been reached by October 1, the president of the United States would act as final arbiter of the dispute. The third demand was the substantive one. Armistice and humanitarian relief Spain could grant without sacrificing sovereignty; presidential arbitration meant that Spain would have to accept, in advance, that an American president would determine the political future of Cuba. That was, in practical effect, a demand for Cuban independence under American mediation.

Woodford delivered the ultimatum to Sagasta and to Foreign Minister Pio Gullon on March 29. The Spanish reply, telegraphed by Woodford on March 31, granted two of the three demands and rejected the third. Spain agreed to revoke the reconcentration order (which had already been substantially wound down under Blanco’s command). Spain agreed to submit the Maine question to arbitration. Spain refused, however, to grant a unilateral armistice on American demand, taking the position that an armistice required a request from the insurgents themselves and could not be ordered by Madrid without abdicating sovereignty. The Spanish counter-proposal offered an armistice if the insurgents requested it and offered Cuban autonomy proceedings beginning on May 4, when the new Cuban parliament was scheduled to convene.

The Spanish reply was thin enough that McKinley could have used it as the casus belli for an April war message. He chose not to. Instead, he authorized Woodford to continue pressing for the armistice on Spanish initiative, and he turned to a different lever: the Vatican.

The Vatican Mediation: April 3 Through April 9

The episode that compresses the McKinley decision arc most usefully runs from April 3 through April 9, 1898, during which Pope Leo XIII attempted a mediation that came astonishingly close to averting the war. The pope, eighty-eight years old and politically active in international affairs in a way that the modern papacy is not, had been approached by the Austrian government and by Cardinal Mariano Rampolla, his Secretary of State, who saw the impending Spanish-American confrontation as both a Catholic-versus-Protestant disaster and a destabilization of the Spanish monarchy that the Vatican wished to preserve. Through Archbishop John Ireland of Saint Paul, Minnesota, an American Catholic prelate with access to the White House, the Vatican offered to mediate.

Ireland arrived in Washington on April 1 and met with McKinley on April 2 and April 3. The proposal was that Pope Leo would propose an armistice that Spain could accept without appearing to capitulate to American pressure, while McKinley would suspend his war message and give the mediation time to work. McKinley was receptive but cautious; he told Ireland that he could not formally request papal mediation (the political consequences in Protestant America would have been severe), but he could decline to refuse it and could allow the diplomatic clock to extend if a Spanish armistice was actually forthcoming.

On April 4, the Spanish ambassadors of the European powers (Britain, France, Germany, Austria-Hungary, Russia, Italy) presented a joint note to McKinley urging restraint and offering their collective good offices for mediation. The note was anodyne and ineffective on its own (McKinley received it politely and returned a brief reply expressing appreciation for the powers’ humanitarian motives), but it provided diplomatic cover for the Vatican track. On April 5, Pope Leo XIII formally requested that Spain proclaim an armistice in Cuba on humanitarian grounds, framing the request as a Catholic appeal independent of American pressure. Sagasta’s cabinet, after intense internal debate in which the Queen Regent Maria Cristina personally intervened, agreed on April 9.

The April 9 Spanish concession was the diplomatic victory the McKinley track had been pursuing since the previous October. Spain proclaimed an immediate armistice in Cuba on humanitarian grounds at the request of the Holy Father. Reconcentration was formally ended. The Cuban parliament was to convene on May 4 with full autonomy. The Maine question would go to arbitration. Every substantive American demand from the March 27 ultimatum had been conceded except the one (immediate armistice on American demand) that Spain had refused to grant for sovereignty reasons but had now granted under the diplomatic cover of papal mediation.

Woodford cabled the news to Washington on April 9 and again on April 10, urging the president in language that approached pleading to give the new framework time. His April 10 cable, preserved in the State Department archives and quoted at length by Offner, included the prediction that “you will get peace in Cuba on your own terms” if no precipitous American action interrupted the new arrangements. Woodford was right. The diplomatic track had won.

The April 11 War Message

McKinley received the April 9 news in time to write a different message than the one he had been drafting. He did not write a different message. The war message he sent to Congress on April 11 included a single paragraph, appended near the end and visibly out of structural rhythm with the rest of the document, acknowledging that Spain had ordered an armistice and “leaving the matter, with that added fact, to your just and careful attention.” The body of the message rehearsed the case for intervention as it had stood before April 9 and asked Congress for authority to use the army and navy of the United States to secure a final settlement.

Why? The honest answer requires three components.

First, McKinley by April 11 no longer believed that any settlement Spain could offer would actually end the Cuban war. The Cuban insurgents had refused, repeatedly and in correspondence captured by both American and Spanish intelligence, to accept any framework short of full independence. Sagasta could not concede full independence without the collapse of the Spanish monarchy at home; Madrid politics made that mathematically impossible. McKinley had concluded, with reasonable evidence, that the new April 9 framework would produce an autonomy that no one in Cuba would accept and that the war on the island would continue under different diplomatic auspices.

Second, McKinley by April 11 had concluded that the political cost of restraint exceeded the political cost of war. His message of April 11 was substantially shorter and less emphatic than what Lodge, Roosevelt, the Republican congressional leadership, and the senatorial votes already publicly committed to intervention demanded. If McKinley had attempted to withhold the message, Congress would have acted without him. The April 7 caucus of Senate Republicans, the April 8 caucus of House Republicans, and the threatened intervention resolutions from the Senate Democrats (which would have placed McKinley in the position of vetoing a war resolution against Spain in advance of the November 1898 midterm elections) had foreclosed the option of continued restraint. McKinley could send a message and shape the eventual resolution, or he could withhold a message and watch Congress send him a resolution he could neither sign without humiliation nor veto without electoral catastrophe.

Third, McKinley by April 11 had concluded that the imperial implications of the war, particularly with respect to Spanish possessions in the Pacific, were containable within an American framework that he could shape from the White House. The Navy Department, under Theodore Roosevelt as Assistant Secretary (and during Secretary John D. Long’s frequent absences, as effective acting secretary), had been making preparations since February for a strike on the Spanish Asiatic Squadron at Manila. Roosevelt’s famous telegram of February 25 to Commodore George Dewey, ordering Dewey to keep the squadron full of coal and to begin offensive operations against the Philippines in the event of war with Spain, had been sent during Long’s afternoon absence and had not been countermanded when Long returned. McKinley had not authorized it specifically but had not reversed it either. The Pacific war was, by April 11, an option already prepared.

The April 11 message asked Congress for authority to use the army and navy to compel a settlement of the Cuban question. It did not ask for a declaration of war. The eventual resolution that emerged from Congress on April 19, after eight days of intense debate in which the Senate added the Teller Amendment disclaiming any American intention to annex Cuba, was a joint resolution authorizing the president to use the armed forces “to such extent as may be necessary.” McKinley signed the resolution on April 20. Spain broke diplomatic relations on April 21. The United States formally declared war by Act of Congress on April 25, retroactive to April 21. Commodore Dewey, operating under Roosevelt’s prepared orders, attacked the Spanish squadron at Manila Bay on May 1 and destroyed it before breakfast. The war lasted ten weeks. The peace treaty signed at Paris on December 10, 1898, transferred Puerto Rico, Guam, and the Philippines from Spain to the United States, with the United States paying Spain twenty million dollars for the Philippines as a face-saving fiction.

The Two-Track Audit

The artifact this article promised was a side-by-side timeline of the two tracks. Here it is, rendered in prose because the article’s formatting rules forbid bullet enumeration in the body.

Beginning with the Maine on February 15: through the rest of February the diplomatic track maintained quiet, with Woodford in Madrid pressing the autonomy-and-humanitarian-relief framework and with McKinley publicly suspending judgment; the political track exploded with Hearst and Pulitzer atrocity coverage but had not yet produced a senatorial majority for intervention. On March 7, Congress unanimously passed a fifty-million-dollar defense appropriation at McKinley’s request, signaling preparedness but not committing to war. On March 8 the diplomatic track received an encouraging signal: Madrid privately indicated willingness to discuss reconcentration relief. On March 9 the political track tightened: Senator William E. Mason of Illinois introduced a resolution calling for immediate recognition of Cuban independence (defeated, but only after considerable arm-twisting).

March 17 was the political-track inflection: Proctor’s speech moved the conservative Senate Republican majority into the intervention camp. The diplomatic track responded: March 27 McKinley sent the three-demand ultimatum; March 31 Spain granted two of three. April 3 through April 5 saw the Vatican mediation come into play on the diplomatic track. April 9 saw the diplomatic victory: Spain ordered the armistice. April 11 the political track foreclosed: McKinley sent the war message anyway, with the April 9 concession reduced to a single paragraph at the end.

The audit makes visible something the conventional narrative obscures: the war began not when the diplomatic track failed but when the political track concluded that no diplomatic success could overcome the domestic political momentum. The McKinley case is therefore the cleanest historical instance of what political scientists call the “structural war”: a war that occurs because the political system requires it, regardless of whether the underlying diplomatic dispute admits resolution. The president’s actual diplomacy in March and April 1898 succeeded. The system overrode it.

Dewey at Manila and the Imperial Surprise

The Pacific dimension deserves a moment of attention because it is where the McKinley war moved beyond Cuba into territorial empire.

Commodore George Dewey’s Asiatic Squadron sailed from Hong Kong on April 27, arrived off the Philippines on April 30, and attacked the Spanish squadron under Rear Admiral Patricio Montojo in Manila Bay at sunrise on May 1, 1898. Dewey’s squadron of four protected cruisers and two gunboats destroyed Montojo’s older and smaller squadron in five hours of action, with American losses of one sailor (from heatstroke) and Spanish losses exceeding three hundred killed. The naval victory was complete; Manila itself, however, was held by Spanish ground forces that Dewey did not have the troops to dislodge. Dewey blockaded the bay and waited for army reinforcements, which began arriving in late June under General Wesley Merritt. The Philippine insurgent leader Emilio Aguinaldo, returned from exile by Dewey’s good offices, organized a Filipino army that besieged Manila by land while the Americans blockaded by sea. Spanish forces in Manila surrendered to a joint American-Filipino operation on August 13, 1898 (technically one day after the armistice, but news of the armistice had not yet reached the Philippines).

The question of what to do with the Philippines after the Spanish defeat was the question for which the McKinley administration had no preexisting answer. The president, in his subsequent memoirs and conversations recorded by visitors (most famously the November 1899 conversation with a delegation of Methodist clergy in which McKinley reportedly described kneeling in prayer and concluding that the United States must “take them all”), portrayed the decision to annex the entire archipelago as a reluctant duty. The historian Walter LaFeber argued in The New Empire that the annexation was a long-prepared imperial design dating back at least to the Harrison administration; Ernest May in his Imperial Democracy argued that the annexation was largely improvised, with McKinley’s strategic calculation driven by fear that Germany or Japan would seize the islands if the United States did not. The archival record supports May more than LaFeber on the specific Philippine decision: there is no evidence of a pre-1898 American plan to acquire the Philippines, and the post-Manila-Bay deliberations show genuine McKinley uncertainty about what to do.

The Treaty of Paris, negotiated by an American commission led by William Day (who had left the State Department to head the commission) between October and December 1898, ceded Puerto Rico, Guam, and the Philippines to the United States. Cuba was made nominally independent, subject to the conditions that would be imposed in the Platt Amendment of 1901. The treaty was signed on December 10, 1898. Senate ratification, which required two-thirds, was secured by a single vote on February 6, 1899, with William Jennings Bryan, the defeated 1896 Democratic presidential nominee, lobbying Democratic senators to vote in favor on the calculation that ratifying would create an imperialism issue Bryan could run on in 1900. Bryan got the issue. McKinley got the empire. The 1900 election rematch returned McKinley to office by a wider margin than 1896.

The Philippine Republic that Aguinaldo had proclaimed in June 1898 refused to accept the American annexation. The Philippine-American War began on February 4, 1899, with the firing on a Filipino patrol by an American sentry on the outskirts of Manila, and continued until July 4, 1902, with intermittent insurgency persisting for years afterward. The war killed approximately 4,200 American soldiers, between 16,000 and 20,000 Filipino combatants, and somewhere between 200,000 and 250,000 Filipino civilians, most of them from war-induced famine and disease. The conflict that McKinley had launched as a humanitarian intervention to end Spanish cruelty in Cuba had become, within a year of the April 11 message, a colonial counterinsurgency in the Western Pacific in which American forces employed methods (concentration camps, the “water cure” interrogation, village destruction) that closely paralleled the Weyler tactics that had originally outraged the American conscience about Cuba.

The paradox is structural, not coincidental. Once a great power begins suppressing an independence movement in a territory it has acquired by war, the operational logic of counterinsurgency converges on a small number of effective methods, and the methods are largely the same regardless of whether the suppressing power is Spain or the United States. McKinley did not anticipate this in April 1898. The structural logic anticipated it for him.

The Complication: Was McKinley’s Reluctance Real?

The case advanced so far rests on a specific empirical claim: that McKinley genuinely tried to avoid war and that the war came against his preference because the political track foreclosed the diplomatic track. The claim is contested. The most important historiographical disagreement in modern scholarship on the 1898 decision is between John Offner, who argues the reluctance was real, and Kristin Hoganson, whose Fighting for American Manhood argues that the reluctance was structurally performed because McKinley’s masculinity politics, embedded in the Civil War veteran identity and the Republican Party’s late-1890s gender ideology, made genuine resistance to war impossible regardless of the president’s private preferences.

The Offner case rests on the Woodford correspondence. The cables and letters between Washington and Madrid from June 1897 through April 1898, recovered from the State Department archives and reprinted with editorial apparatus in the Foreign Relations of the United States series, show a president who repeatedly pressed his minister to extract diplomatic concessions sufficient to avoid intervention. The April 9 Spanish concession was the kind of outcome McKinley had been working toward. If the reluctance had been merely performed, the diplomatic effort would have been pro forma, and the cables would show ritual gestures rather than substantive demands. They do not. They show real demands, real Spanish movement in response, and a genuine diplomatic effort that almost succeeded.

The Hoganson case rests on a different evidentiary base. She points to the gender politics of the late-nineteenth-century American Republican Party: the Civil War veteran culture that defined political legitimacy through martial service, the imperialist intellectuals (Brooks Adams, Henry Cabot Lodge, Theodore Roosevelt, Alfred Thayer Mahan) who explicitly framed national power in terms of masculine vigor and warned of national emasculation through restraint, and the press culture that mocked McKinley personally as effeminate (the cartoons of him as “Mark Hanna’s lap dog” or in a woman’s bonnet had been a Hearst staple since the 1896 campaign). Within this discursive structure, Hoganson argues, McKinley could not extend the diplomatic track indefinitely without absorbing political damage that would have made his presidency unrecoverable. The reluctance was real as a private preference but unworkable as a public position. The diplomatic effort was sincere but constrained from the start by the knowledge that it could not be allowed to delay action past a politically determined point.

The Hoganson reading is partly correct and partly overdetermined. It is correct that McKinley could not have indefinitely extended the diplomatic track without political collapse. It is correct that the masculine-honor culture of the period constrained his options. But it is overdetermined to argue that the constraint made the reluctance epiphenomenal: McKinley’s diplomatic effort did real work, did extract real Spanish concessions, and did come within forty-eight hours of producing a settlement on substantially American terms. The fact that the political track foreclosed the settlement does not mean the diplomatic track was a charade. It means that two real political forces collided and one of them won.

David Trask, in his still-standard military history The War With Spain in 1898, takes a position between Offner and Hoganson that the present article endorses. The reluctance was real, the diplomatic effort was substantive, but the diplomacy could not have succeeded on the timetable Spanish domestic politics required. Even if McKinley had extended the deadline by a month, Spanish concession on Cuban independence would have collapsed the Sagasta government and probably the Bourbon monarchy. Sagasta could grant armistice; he could grant autonomy; he could even, under maximum pressure, accept arbitration. He could not grant independence and survive the resulting domestic crisis in Madrid. The diplomatic track was therefore bounded above by what Spanish politics could absorb, and below by what Cuban insurgents would accept. The space between those boundaries was narrow and probably empty by April 1898. McKinley’s diplomacy was, in that sense, real but predestined to fail.

Two further complications deserve mention. The first is the question of whether the Philippines were a long-prepared imperial design or an improvisation. Walter LaFeber’s New Empire argued for design, citing the pre-1898 development of Mahan’s naval strategy, the State Department’s interest in coaling stations and naval bases in the Western Pacific, and the 1893 Hawaii crisis as building blocks of an Asia-Pacific imperial framework that the Philippines completed. Ernest May’s Imperial Democracy and Lewis Gould’s biography argued for improvisation, with the Philippines acquisition driven by the post-Manila-Bay realization that the United States either had to acquire the islands or watch a European or Japanese power do so. The archival record from the McKinley papers, the Long diaries, and the cabinet meetings of June through August 1898 supports May and Gould: the post-Dewey planning shows real uncertainty within the administration about what to do with the Philippines, with annexation emerging as the default after the alternative options (return to Spain, neutralization under international guarantee, transfer to another power, independence under American protection) were judged each unworkable. The imperialist intellectual framework that made annexation thinkable preexisted 1898; the specific decision to annex the Philippines was contingent on events after May 1.

The second complication is more uncomfortable. The narrative of McKinley’s reluctance, accurate as it is on the Cuban question, has the effect of making the Philippine annexation appear similarly reluctant - a decision made for high-minded reasons after careful consideration. The actual Philippine decision was made within a political and intellectual framework that had long since dismissed the question of Filipino self-determination as irrelevant. Aguinaldo’s June 12 declaration of Philippine independence was treated by the McKinley administration as a legally null act by an entity the United States did not recognize. The Filipino role in the Manila campaign was treated as auxiliary; the August 13 surrender of Manila to combined American and Filipino forces was negotiated to ensure that Filipino troops did not enter the city, lest they assume status as co-occupiers. The legal posture that the Philippines were Spanish territory transferred to the United States by the Treaty of Paris, with the wishes of the inhabitants legally irrelevant, was assumed throughout the 1898 deliberations. McKinley’s reluctance on Cuba did not extend to the Philippines because the framework of Filipino self-determination was not on the McKinley desk in the way that the framework of Cuban self-determination was, and the absence of that framework was not an oversight; it was a feature of the imperial structure within which the entire 1898 decision arc operated.

The Verdict

The McKinley paradox, as introduced at the outset, is the verdict. The April 1898 war was structural, not presidential. McKinley genuinely tried to avoid it, the diplomatic track came within forty-eight hours of succeeding, and the war came anyway because the political track foreclosed any diplomatic outcome that did not produce Cuban independence on a timetable Spanish politics could not accept. The reluctance was real; the structural pressure overrode it.

This verdict has two corollaries.

The first corollary is that the conventional teaching narrative of 1898 - yellow journalism plus the Maine plus a weak president equals war - is wrong in its causal structure. Yellow journalism was real but had been at full volume for years without producing congressional war votes. The Maine was real but did not by itself produce the war (the seven weeks between the explosion and the April 11 message included sustained diplomatic activity that was actually succeeding). McKinley was not weak; he extracted from Madrid every substantive concession the diplomatic situation could possibly produce. The variable the conventional narrative misses is the political mobilization that Proctor’s March 17 speech crystallized, the Senate caucus that committed to intervention by early April, and the impossibility of withholding presidential leadership once Congress was visibly prepared to act without him. The war happened because the American political system had become structurally committed to it, and a president whose private preference ran the other way could shape the message but could not stop the train.

The second corollary is that the McKinley case is the foundational instance of the imperial-presidency pattern in foreign policy. The structural war power that the McKinley case revealed - the capacity of the political system to produce executive-led wars even against the preferences of the executive - is the precondition for every subsequent imperial-presidency expansion. Theodore Roosevelt at Panama in 1903, Wilson in the Caribbean and Mexico from 1913 onward, Wilson on entry to the World War in 1917, Franklin Roosevelt’s pre-Pearl Harbor naval war in the Atlantic, Truman’s June 1950 Korea commitment without congressional declaration, Johnson’s August 1964 Tonkin Gulf escalation, George H. W. Bush’s 1990 Gulf deployment, and George W. Bush’s 2003 Iraq War all worked within a constitutional and political framework that the McKinley case had legitimated. The president could lead the country into war on his own diplomatic and military initiative, with Congress in a confirming rather than originating role, because the McKinley case had demonstrated that congressional war-making could be a downstream consequence of executive and political-system action rather than an upstream check on it.

The argument is not that McKinley invented the imperial presidency. The argument is that the McKinley case revealed the structural conditions under which the presidency would expand toward an imperial form, and that the foreign-policy expansions of the twentieth century operated within and through those conditions. The reluctance of the originating executive does not diminish the structural pattern. If anything, McKinley’s reluctance amplifies the pattern’s significance: if a war could occur against the private preferences of the chief executive, then no theory of presidential restraint can serve as an effective constraint on the war power. The constraint, if any, has to come from somewhere outside the president’s preferences.

The Legacy: From Havana to Baghdad

The legacy of the April 11, 1898 war message operates on three tracks: the immediate territorial outcome, the legal-constitutional architecture that the McKinley decisions and their judicial reception established, and the long-term imperial template that subsequent presidents inherited and extended.

The Immediate Territorial Outcome

The Treaty of Paris settled the territorial outcome by transferring Spanish sovereignty over Puerto Rico, Guam, and the Philippines to the United States and by ending Spanish sovereignty over Cuba while not transferring it to anyone in particular. The Cuban arrangement, framed by the Teller Amendment’s American disclaimer of any annexationist intention, was substantially modified within three years.

The Platt Amendment, drafted by Secretary of War Elihu Root and introduced as an amendment to the Army Appropriations Act of 1901, conditioned the withdrawal of American military forces from Cuba on Cuban acceptance of eight specific provisions in the new Cuban constitution. The provisions required Cuba to refrain from entering treaties impairing its independence, restricted Cuban public debt, granted the United States a perpetual right to intervene “for the preservation of Cuban independence, the maintenance of a government adequate for the protection of life, property, and individual liberty,” obligated Cuba to validate American actions during the military occupation, required Cuba to lease coaling and naval stations to the United States (the Guantanamo lease followed in 1903), and required incorporation of the eight provisions into the Cuban constitution itself. The Cuban constitutional convention accepted the Platt Amendment in June 1901 by a vote of fifteen to fourteen, under explicit notice from the American military governor Leonard Wood that withdrawal would not occur otherwise. The Teller Amendment’s disclaimer of annexation was thereby reconciled with a Cuban “independence” so heavily qualified by Platt that the practical American position in Cuba between 1901 and 1934 (when the Platt Amendment was abrogated under Franklin Roosevelt’s Good Neighbor policy) approached a quasi-protectorate.

The Philippine arrangement was more straightforward and more brutal. The Philippine-American War, fought between February 1899 and July 1902 with intermittent insurgency persisting in Mindanao and the southern islands until 1913, was the bloodiest counterinsurgency the United States had waged to that date and remained so until Vietnam. The American methods that drew the loudest contemporary criticism (the “water cure” interrogation technique that Senator Henry Cabot Lodge’s own committee documented, the General Order 100 reconcentration of civilian populations on Marinduque and elsewhere, the destruction of Filipino villages in retaliation for guerrilla activity) were largely the same methods Weyler had used in Cuba and that had originally drawn American outrage. The Senate hearings of 1902 chaired by Lodge produced a documentary record of these methods that is one of the more substantial American military investigations of its century, but the political consequences were modest: a handful of officer court-martials, the elevation of General Adna Chaffee to chief of staff, and the broader political effect of normalizing methods that had been unthinkable when Spanish forces employed them six years earlier.

Puerto Rico became an unincorporated territory whose constitutional status was developed across a series of Supreme Court decisions (the Insular Cases) between 1901 and 1922. The basic doctrinal result was that Puerto Rico was American territory for some constitutional purposes (the Bill of Rights’ fundamental protections applied) but not American territory for others (the uniformity clause for tariffs did not apply; the right to a jury trial in criminal cases was not constitutionally required). Puerto Ricans became United States citizens by the Jones Act of 1917, with citizenship that was not accompanied by representation in Congress (the resident commissioner is a non-voting delegate) or by the vote for president. The status remains contested through the present, with statehood, independence, and continued territorial status all having political constituencies.

Guam followed a similar but less politically active trajectory: unincorporated territory, citizenship granted by act of Congress (1950), substantial American military presence persisting through the twentieth century and into the present.

The Insular Cases: Constitutional Architecture

The Insular Cases of 1901 and the years following are the constitutional architecture within which the post-1898 imperial expansion operated. Downes v. Bidwell (1901), Dorr v. United States (1904), and a half-dozen related decisions developed the doctrine that the United States Constitution did not automatically extend to all territories acquired by the United States, with the distinction between “incorporated” territories (those on the path to statehood, to which the Constitution applied in full) and “unincorporated” territories (those not on the path to statehood, to which only “fundamental” constitutional provisions applied) becoming the controlling framework.

The Insular Cases doctrine was the legal innovation that made permanent American empire possible without requiring either the assimilation of acquired territories as future states (the framework that had governed continental expansion since 1789) or the relinquishment of those territories to local self-government. The doctrine has been criticized by constitutional scholars from Christina Duffy Burnett to Bartholomew Sparrow as resting on a racial premise (the territories acquired in 1898 contained populations the Court could not contemplate as future state-equivalent communities) that was largely unspoken but unmistakable in the opinions. The doctrine has nevertheless remained operative through the present and provides the constitutional framework within which the United States continues to govern Puerto Rico, Guam, the U.S. Virgin Islands, the Northern Mariana Islands, and American Samoa.

The Long-Term Imperial Template

The McKinley case provided subsequent presidents with a template that operated through six durable features. Each feature is visible in the 1898 decision arc, each has subsequent twentieth-century instantiations, and each is constitutive of what political scientists call the modern imperial presidency.

First, executive-prepared military action that creates facts on the ground before congressional deliberation can occur. The Roosevelt-Dewey telegram of February 25, 1898, prepared the Philippine operation weeks before the war message and was operationalized within six days of the declaration. This pattern, in which the president and the executive branch position military forces such that an order to act can produce immediate consequences while congressional debate is still developing, recurs across the twentieth century in Wilson’s pre-1917 naval preparations, FDR’s pre-Pearl Harbor convoy and patrol operations in the Atlantic, Truman’s June 25 to June 30, 1950 sequence of Korea decisions made before Congress was consulted, Johnson’s August 4, 1964 Tonkin Gulf retaliation, and Bush’s January 16, 1991 Desert Storm initiation eight days after the congressional authorization that had still left the executive decision open.

Second, congressional resolutions that authorize the use of force on terms broad enough to permit subsequent executive expansion of war aims. The April 19 joint resolution authorized intervention to compel Spanish withdrawal from Cuba; the eventual peace acquired the Philippines. The August 7, 1964 Gulf of Tonkin Resolution authorized response to North Vietnamese attacks on American forces in the gulf; the eventual war extended to a half-million American troops fighting across South Vietnam. The October 16, 2002 Iraq Resolution authorized force “as he determines to be necessary and appropriate” against Iraq; the eventual war became a thirteen-year occupation with mission scope extending well beyond the original authorization. The McKinley case established the pattern by which congressional war resolutions tend to be drafted in language broad enough to permit subsequent executive interpretation of war aims.

Third, the establishment of a public-and-press atmosphere in which congressional refusal to authorize action carries higher political costs than congressional authorization of action whose ultimate scope is uncertain. The McKinley case made visible that a Republican Senate could not refuse intervention in Cuba in April 1898 without facing November 1898 midterm electoral consequences. The same dynamic operated in 1917 (Senate Democrats faced the same calculus on Wilson’s war message), in 1941 (after Pearl Harbor the political cost of opposition was infinite), in 1950 (Korea was technically a police action, but the political pressure on congressional Republicans not to obstruct Truman was intense), in 1964 (Tonkin Gulf passed the House unanimously and the Senate with two no votes), and in 2002 (the Iraq Resolution passed with majority Democratic support in the Senate because individual senators with presidential ambitions calculated that opposing the resolution would cost them more than supporting it).

Fourth, the acquisition or operational deployment of territories and bases that outlast the original conflict and acquire constituencies for permanent retention. The Philippines were held for forty-eight years; Guam, Puerto Rico, and the Northern Marianas remain American territories; Guantanamo’s lease from Cuba has been continuously paid (rejected by Cuba since 1959 but maintained by the United States) and the base has operated continuously since 1903. The pattern of base-and-territory acquisition that does not relinquish on schedule is one of the most durable features of the post-McKinley imperial structure, and it produces its own subsequent justifications: American forces in Germany, Japan, Korea, and Bahrain are continuations of post-conflict deployments that became permanent through institutional persistence rather than deliberate strategic decision.

Fifth, the development of legal-doctrinal frameworks (the Insular Cases for the 1898 acquisitions; the National Security Act of 1947 and its progeny for the Cold War; the post-2001 detention and surveillance frameworks for the Global War on Terrorism) that integrate the acquired powers and territories into the constitutional structure without requiring the political system to confront the cumulative scale of expansion. The Insular Cases doctrine, by drawing distinctions between fundamental and non-fundamental constitutional provisions, enabled the United States to govern Puerto Rico in a manner that would have been constitutionally unthinkable if Puerto Rico had been a state or an incorporated territory. The same doctrinal innovation, applied to subsequent acquisitions and to subsequent emergency powers, is one of the principal mechanisms by which the imperial-presidency expansion is rendered legally invisible.

Sixth, and most importantly for our purposes, the structural feature that the McKinley case revealed: the capacity of the political system to produce wars and territorial commitments that proceed even when the chief executive’s private preference runs the other way. This is the feature for which the McKinley case is irreplaceable as historical evidence. A war that occurred against the preferences of a peace-preferring president demonstrates that presidential restraint is not a sufficient constraint on the war power, because the war power can operate around the president when the political system has mobilized around an intervention. Subsequent twentieth-century wars have generally been initiated by presidents who wanted them; the McKinley case is the cleanest evidence that presidents who do not want a war can be carried into one by the structural pressures of the political system, and therefore that any constitutional theory of war-power restraint that rests on presidential reluctance is theoretically inadequate.

The reader who has read the series article on the wartime executive power that never returned (which threads through every wartime presidency from Madison through George W. Bush, documenting that executive powers claimed during wars are almost never relinquished afterward) will recognize the McKinley case as the foreign-policy bookend of that pattern. The McKinley case shows how wars begin under the modern structural conditions; the wartime-power pattern shows how the resulting expansion ratchets forward across the subsequent century. Together they form the foreign-policy core of the imperial-presidency thesis that runs through this series.

The reader who reaches forward in the series to the Theodore Roosevelt at Panama article (which examines Roosevelt’s November 1903 recognition of the Panamanian secession from Colombia and the subsequent canal-zone acquisition) will see the imperial template McKinley established being deployed by a successor who needed no reluctance to be navigated and no congressional foreclosure to be overcome. Roosevelt simply did what the McKinley case had demonstrated could be done. The five subsequent presidents who built canal-zone-equivalent operations across the Caribbean and Central America between 1903 and 1933 operated within the same framework.

The reader who reaches forward to the LBJ Gulf of Tonkin article will see the structural war pattern in its most refined twentieth-century form: an executive who deliberately created the conditions under which Congress could not refuse a war resolution, with the structural conditions McKinley had revealed as available being exploited rather than navigated. The McKinley case showed reluctance overrun by structure. The Johnson case showed structure deployed by design. The two cases together bracket the foreign-policy chapter of the imperial-presidency thesis: McKinley’s reluctance demonstrates the structural conditions are real and independent of presidential preference; Johnson’s deployment demonstrates that subsequent presidents could use those structural conditions as a tool. The constitutional war-making system that the framers had designed in 1787, in which Congress would deliberate and declare and the president would execute, was by 1965 a system in which the president created the conditions, the executive branch positioned the forces, the political system foreclosed congressional refusal, and the resulting war was nominally authorized by a resolution Congress could not have refused without unacceptable political cost.

This is, in 1898 and again in 1964 and again in 2002, structurally the same system. The McKinley case is where it became visible for the first time.

Frequently Asked Questions

Q: Did McKinley actually try to avoid war with Spain?

Yes, and the documentary record is unambiguous on this point. The Woodford correspondence preserved in the State Department archives shows the president pressing his minister in Madrid to extract diplomatic concessions sufficient to avoid intervention from the appointment of Woodford in June 1897 through the April 9, 1898 Spanish armistice concession. The pressure included the March 27 three-demand ultimatum, the willingness to receive Vatican mediation in early April, and the explicit instruction to Woodford to keep diplomatic channels open even as congressional pressure intensified. John Offner’s An Unwanted War is the definitive archival reconstruction and its conclusion that McKinley genuinely sought a settlement is supported by the contemporary cables, the cabinet meeting records, and the president’s private correspondence with Mark Hanna and others. The reluctance was real, even if Kristin Hoganson is correct that the masculinity politics of the period made indefinite continuation of restraint politically impossible. Real reluctance under structural constraint is the accurate description.

Q: What did the Spanish government actually concede on April 9, 1898?

Spain conceded an immediate armistice in Cuba on humanitarian grounds at the request of Pope Leo XIII, the formal termination of the reconcentration policy (substantially wound down already under General Blanco’s command since November 1897), the convening of the Cuban parliament with full autonomous powers on May 4, 1898, and the submission of the Maine question to arbitration. The only item from McKinley’s March 27 ultimatum that Spain refused was the demand for an armistice on direct American compulsion (which the Spanish accepted indirectly through papal mediation). Stewart Woodford, the American minister in Madrid, telegraphed Washington on April 10 with the news that the diplomatic track had effectively succeeded and pleaded with the administration to give the new framework time to work. McKinley sent the war message anyway on April 11, with the Spanish concession reduced to a single paragraph at the end of a document otherwise written as if the concession had not occurred.

Q: Did Spain actually blow up the USS Maine?

Almost certainly not. The 1898 American Court of Inquiry under Captain Sampson concluded that an external mine had caused the explosion, but the diving technology and metallurgical analysis available in 1898 were inadequate to support that conclusion confidently. The 1976 investigation conducted by Admiral Hyman Rickover and a team of naval engineers analyzing the available structural evidence concluded that the most probable cause was a spontaneous combustion fire in the forward coal bunker that ignited the adjacent six-inch reserve magazine through the bulkhead. The 2002 Naval History and Heritage Command review reached the same conclusion with greater confidence. The Spanish Court of Inquiry that sat in 1898 had correctly identified the internal-explosion cause from the available evidence and had been ignored at the time. The Maine slogan that drove war pressure in 1898 was, in this sense, based on a misunderstanding of the actual physics of the explosion, although the political force the slogan exerted operated entirely independently of the underlying engineering question.

Q: Why did Senator Redfield Proctor’s March 17 speech matter so much?

Proctor was a Republican from the conservative business wing of the party, founder of the Vermont Marble Company, the dryest and most fact-oriented Republican senator, and a man with no prior reputation for interventionist sympathies. His Cuba speech, delivered after three weeks of personal travel through the western provinces, described the reconcentration camps in a statistical, businesslike register that established the humanitarian catastrophe as documented fact rather than yellow-press exaggeration. The speech converted the conservative business Republican coalition that had previously aligned with McKinley’s diplomatic caution into the intervention camp. Henry Cabot Lodge, John Bassett Moore, William Allen White, and Roosevelt all left written observations describing the Proctor speech as the political turning point. After March 17, McKinley knew that congressional restraint could not be sustained much longer, and his subsequent cables to Woodford reflect that knowledge. The speech is therefore the substantive cause of the war timeline, more directly than the Maine, the yellow press, or any other single event.

Q: Were the Philippines acquired by design or by accident?

The historical evidence supports neither pure design nor pure accident but rather contingent improvisation within a long-standing imperial framework. Walter LaFeber’s New Empire argued for design, citing the pre-1898 development of Mahan’s naval strategy and State Department interest in Pacific coaling stations. Ernest May’s Imperial Democracy and Lewis Gould’s biography argued for improvisation, citing the absence of any documented pre-1898 plan to acquire the Philippines specifically. The archival record from the McKinley papers, the John D. Long Navy Department diaries, and the cabinet meetings from May through September 1898 supports May and Gould: the post-Dewey administration showed genuine uncertainty, with annexation emerging as the default option after alternatives (return to Spain, neutralization, transfer to another power, Filipino independence under American protection) were judged unworkable. The intellectual framework that made annexation thinkable was longstanding; the specific decision was contingent on the post-May 1 facts on the ground.

Q: How did the Teller Amendment fit into the war declaration?

The Teller Amendment, sponsored by Senator Henry Teller of Colorado and incorporated into the April 19, 1898 joint resolution authorizing military action, disclaimed any American intention to “exercise sovereignty, jurisdiction, or control” over Cuba and committed the United States to leave the island to its people upon pacification. The amendment passed easily because both pro-annexation and anti-annexation senators could vote for it (annexationists believing the disclaimer was political theater that would not bind future policy, anti-annexationists believing the disclaimer was a substantive commitment). The Teller Amendment applied only to Cuba; nothing in the resolution restricted American action with respect to other Spanish possessions, which is the gap through which the Philippines, Puerto Rico, and Guam acquisitions subsequently passed. The disclaimer was honored in form by the 1902 American withdrawal from Cuba but was effectively gutted by the 1901 Platt Amendment that conditioned the withdrawal on Cuban acceptance of perpetual American right of intervention.

Q: What was the Platt Amendment and how did it limit Cuban independence?

The Platt Amendment, drafted by Secretary of War Elihu Root and attached to the Army Appropriations Act of 1901, conditioned American military withdrawal from Cuba on the incorporation of eight specific provisions into the new Cuban constitution. The provisions restricted Cuban treaty-making, capped Cuban public debt, granted the United States a perpetual right to intervene in Cuban affairs for the protection of life, property, and individual liberty, validated American military-government actions during the occupation, required Cuba to lease naval and coaling stations to the United States (producing the Guantanamo lease in 1903), and required incorporation of the eight provisions into the Cuban constitution itself. The Cuban constitutional convention accepted Platt by a single vote in June 1901, under explicit notice from military governor Leonard Wood that withdrawal would not otherwise occur. The amendment operated continuously from 1901 to 1934, when it was abrogated under Franklin Roosevelt’s Good Neighbor policy, leaving the Guantanamo lease as the only surviving Platt-era arrangement.

Q: How many Cubans died in the reconcentration camps?

The estimates range widely and the precise number is contested. Contemporary American consular reports from late 1897 and 1898 estimated Cuban civilian deaths in the reconcentration camps at between 200,000 and 400,000. Modern Cuban historians, including Jorge Ibarra, have produced lower estimates in the range of 150,000 to 200,000 based on demographic reconstruction. The American historian Louis Perez Jr., whose work on the Cuban war is the standard, suggests 170,000 as a reasonable median estimate. The order-of-magnitude figure is one hundred thousand or more, with most of the deaths attributable to disease (smallpox, dysentery, malaria) and malnutrition rather than to direct violence. The reconcentration camp toll exceeded the combined military casualties of the entire 1895 to 1898 Cuban war by a factor of approximately five. The humanitarian dimension of the American intervention was therefore not invented by the yellow press; it was based on conditions that genuinely warranted humanitarian concern, even if the choice of remedy (war and territorial acquisition) was disproportionate to the diagnosis.

Q: How did the Philippine-American War connect to the Spanish-American War?

The Philippine-American War began on February 4, 1899, when an American sentry fired on a Filipino patrol on the outskirts of Manila, and officially ended on July 4, 1902, with continued insurgency persisting in Mindanao and the Sulu archipelago until 1913. The war killed approximately 4,200 American soldiers, between 16,000 and 20,000 Filipino combatants, and between 200,000 and 250,000 Filipino civilians, mostly from war-induced famine and disease. The Spanish-American War, by contrast, killed 385 American combatants from enemy action (and roughly 2,000 from disease) over its ten-week duration. The Philippine war was therefore approximately ten times deadlier for American forces and at least a hundred times deadlier for native populations than the war that produced the acquisition. The methods American forces employed in the Philippines (reconcentration on Marinduque under General Bell, the water cure interrogation, village destruction in retaliation for guerrilla activity) closely paralleled the Weyler methods that had outraged American conscience about Cuba four years earlier.

Q: What is the imperial presidency thesis and how does the McKinley case support it?

The imperial presidency thesis, advanced most influentially by Arthur Schlesinger Jr. in his 1973 book of that title, holds that the constitutional balance among the three branches of the federal government has shifted across the twentieth century toward an executive that is dominant in foreign policy and increasingly autonomous from congressional oversight in war-making, intelligence operations, and emergency action. The McKinley case is the foundational foreign-policy instance of the thesis because it reveals the structural conditions under which executive-led wars become possible even against the private preferences of the executive. The reluctance of McKinley demonstrates that the structural war-making capacity of the modern American political system operates independently of presidential preference, which means that constitutional theories of war-power restraint that depend on presidential reluctance are theoretically inadequate. The pattern that the McKinley case revealed (executive-prepared military action, broad congressional authorizations, public-press pressure that makes congressional refusal politically impossible, territorial acquisitions that persist beyond the original conflict) is the pattern that subsequent twentieth-century wars instantiate.

Q: How does the McKinley war compare to other late-nineteenth-century imperial expansions?

The Spanish-American War occurred within the broader late-nineteenth-century period of European colonial expansion known as the New Imperialism, during which Britain, France, Germany, Belgium, Italy, Russia, and Japan acquired or consolidated territorial empires across Africa and Asia. The American expansion was distinctive in several respects: it occurred later than the major European colonial acquisitions (most of Africa had been partitioned at the 1884-85 Berlin Conference, fourteen years before the Spanish-American War), it acquired territories from a fellow European imperial power rather than from indigenous polities, and it was carried out under a constitutional framework that nominally rejected colonial empire. The American case also produced a distinctive legal framework, the Insular Cases doctrine of “unincorporated territories,” that allowed permanent imperial possession without requiring the political integration of the acquired territories. The McKinley empire was, in this sense, a late and distinctively legalistic version of a phenomenon that was the dominant feature of great-power politics in the half-century before the First World War.

Q: Was the war fundamentally about Cuba, sugar economics, or naval strategy?

The motivations for the American intervention operated on three levels. The proximate cause, occupying the public discourse and the congressional resolutions, was humanitarian concern over Cuban suffering under Spanish colonial rule. The intermediate cause, occupying business interests and a portion of the political coalition, was the disruption of American economic interests in Cuban sugar and tobacco production, which had been damaged by the Cuban war and by the Spanish economic policies surrounding it. The deeper cause, occupying intellectuals such as Mahan, Lodge, and Brooks Adams, was the strategic imperative for American naval power to acquire Pacific coaling stations and Caribbean bases sufficient to project force into both oceans. The three levels operated simultaneously and reinforced each other: the humanitarian frame mobilized public support, the economic frame mobilized business support, and the strategic frame shaped the eventual territorial acquisitions (the Philippines for the Pacific, Puerto Rico and Guantanamo for the Caribbean). The intervention served all three constituencies, which is why it was politically irresistible despite McKinley’s personal preference for restraint.

Q: Why did the Senate confirm the Treaty of Paris by only one vote?

The Treaty of Paris ratification vote of February 6, 1899, was 57 to 27 in favor, exactly the two-thirds majority required, with the closeness reflecting the substantial anti-imperialist opposition led by Senator George Frisbie Hoar of Massachusetts, former president Grover Cleveland (out of office but politically active), Mark Twain, Andrew Carnegie, William Jennings Bryan, and the Anti-Imperialist League founded in November 1898. The opposition argued that permanent American acquisition of populated territories with non-white populations was constitutionally incompatible with the American republic and would corrupt American political institutions over time. The decisive factor in the narrow ratification was Bryan’s lobbying of Democratic senators to vote in favor, on the political calculation that ratification would create an imperialism issue Bryan could run on in 1900. Bryan got his issue and lost the 1900 election by a wider margin than 1896. The treaty he had helped to pass produced the Philippine-American War, the Insular Cases, and the framework of unincorporated territories that continues to operate today.

Q: What was the “splendid little war” phrase and where did it come from?

The phrase “splendid little war” was coined by John Hay, the American ambassador to Britain who would shortly succeed William Day as Secretary of State, in a private letter to Theodore Roosevelt dated July 27, 1898, sent two weeks after the American victory at Santiago de Cuba. Hay’s letter described the conflict, then nearly concluded with respect to Cuban operations, as “a splendid little war, begun with the highest motives, carried on with magnificent intelligence and spirit, favored by that fortune which loves the brave.” The phrase has been quoted ever since as a summary of the conventional American memory of the war. The actual war, including the Philippine campaign that the phrase preceded and that lasted three and a half more years and killed two orders of magnitude more people than the Cuban operations, was decidedly less splendid and less little than Hay’s letter implied. The phrase has become one of the most ironically cited summaries in American historical memory, invoked as a synecdoche for the gap between the popular memory of 1898 and the actual consequences of the McKinley war.

Q: How did the war affect McKinley’s political standing?

McKinley emerged from the war with substantially enhanced political standing. The 1898 midterm elections produced Republican gains in both the House and Senate (the historic pattern is for the incumbent president’s party to lose seats in midterm elections, making the 1898 result a striking departure), the 1900 election rematch against William Jennings Bryan returned McKinley to office by a margin of 292 electoral votes to 155 (compared with 271 to 176 in 1896), and the popular vote margin widened from 4.3 points in 1896 to 6.2 points in 1900. McKinley’s reluctance about the war was forgotten in the political memory; he was treated by 1900 as a successful war president, which substantially he was on his own terms (the war had achieved its stated aims in Cuba and produced unanticipated but, by then, broadly accepted imperial expansion in the Pacific). His September 1901 assassination by Leon Czolgosz at the Buffalo Pan-American Exposition cut short what would likely have been a second term focused on tariff and trust policy, leaving the imperial consolidation to Theodore Roosevelt.

Q: What would have happened if McKinley had given the April 9 Spanish concession time to work?

This is the central counterfactual of the 1898 decision arc, and the most careful historical analysis suggests the diplomatic settlement would probably not have held. The Cuban insurgents had refused, repeatedly and in correspondence captured by both American and Spanish intelligence, to accept any framework short of full independence. Sagasta’s government could not concede full independence without political collapse in Madrid. The most that the diplomatic track could realistically have produced was a temporary armistice followed by continued fighting once the spring campaigning season resumed. McKinley would then have faced the same domestic political pressures in early 1899 that he faced in early 1898, with the added complication that Congress had been further mobilized for intervention. The diplomatic track was therefore likely doomed to fail on the underlying Cuban question even if the April 1898 timing had been extended. The counterfactual that asks whether war could have been avoided altogether is harder to answer than the counterfactual that asks whether war could have been delayed for a year. The honest answer is probably delayed, almost certainly not avoided, and the delay would not have changed the eventual American territorial acquisitions.

Q: How does the McKinley case relate to the post-2001 Authorizations for the Use of Military Force?

The September 18, 2001 Authorization for the Use of Military Force (AUMF) authorizing the president to use force against those responsible for the September 11 attacks, and the October 16, 2002 Iraq Resolution, are direct lineal descendants of the April 19, 1898 joint resolution authorizing intervention in Cuba. Each authorization was drafted in language broad enough to permit subsequent executive interpretation of war aims, each passed under public-press conditions that made congressional refusal politically costly, and each produced subsequent military operations whose scope substantially exceeded what congressional debate at the time had contemplated. The 2001 AUMF in particular has been invoked by three successive presidential administrations to authorize operations in at least eighteen countries against organizations whose connection to the September 11 attacks varies from direct to tenuous to absent. The structural pattern that the McKinley case revealed (executive-led war whose scope grows beyond the original congressional authorization, with the political system unable to revisit the authorization once enacted) is one of the most durable features of modern American constitutional practice, and the McKinley case is where it first becomes visible in the historical record.

Q: How is the McKinley case taught compared to how the documentary record supports?

The conventional textbook narrative compresses 1898 into a four-step story: Cuban revolt, yellow journalism, the Maine, McKinley caves and asks for war. This compression obscures the substantive diplomatic effort that actually came close to averting the conflict, misidentifies McKinley as weak rather than constrained, attributes causal weight to the Maine that the seven-week diplomatic interval between February 15 and April 11 should have made impossible, and entirely omits the Proctor speech of March 17 that was the actual political turning point. The documentary record, particularly the Foreign Relations of the United States volumes for 1898 (containing the Woodford correspondence), the Long diaries (containing the Navy Department deliberations), the cabinet records from the period, and the contemporary Senate Foreign Relations Committee proceedings, supports a substantially more complex narrative in which McKinley’s diplomacy was a serious effort that nearly succeeded and the war came through political mobilization that the diplomacy could not have stopped on the available timetable. The teaching narrative is wrong because it is too simple, not because the events it summarizes did not occur.

Q: What primary sources should a serious student read?

The essential primary sources for the McKinley decision arc are the Foreign Relations of the United States volumes for 1898 (which contain the Woodford correspondence with State, the European-powers diplomatic exchanges, and the Spanish responses); McKinley’s April 11, 1898 war message itself (widely available in published documentary collections); the report of the United States Court of Inquiry on the Maine (March 21, 1898); Senator Redfield Proctor’s March 17, 1898 Senate speech (Congressional Record); the April 19 joint resolution and the Teller Amendment as enacted; the Treaty of Paris of December 10, 1898; and Pope Leo XIII’s April 5 mediation correspondence. Secondary essential reading includes John Offner’s An Unwanted War for the diplomatic reconstruction, Lewis Gould’s Presidency of William McKinley for the biographical and administrative dimensions, David Trask’s War With Spain in 1898 for the military operations, Kristin Hoganson’s Fighting for American Manhood for the gender-politics interpretation, and Louis Perez Jr.’s Cuba Between Empires for the Cuban dimension. The combination of these sources permits a reader to reconstruct the 1898 decision arc with a precision the conventional textbook narratives do not approach.

Q: How should we evaluate McKinley as a president?

McKinley occupies an awkward position in the historical reputation: insufficiently regarded by the immediate posthumous generation (because Theodore Roosevelt’s first-magnitude personality overshadowed McKinley’s quieter style), partially rehabilitated by the C-SPAN, Siena, and similar twenty-first-century presidential rankings (where McKinley typically appears in the second or third quartile), and increasingly assessed in the context of his actual policy choices on monetary policy (the 1900 Gold Standard Act), tariff policy (the 1897 Dingley Tariff that reversed Cleveland’s reductions), trust regulation (which McKinley largely left alone, allowing the merger wave that produced U.S. Steel, Standard Oil, and American Tobacco to proceed), and the imperial expansion. The 1898 decision arc is the dominant event of his presidency, and its assessment depends heavily on whether one credits his reluctance (which moves him toward the sympathetic interpretation, in which an essentially decent man was carried into a war he did not want) or weighs his unwillingness to use the presidency to resist the political mobilization (which moves toward a less sympathetic interpretation, in which a constitutionally available power to resist congressional war pressure was forfeited). The honest assessment is mixed, with McKinley emerging as a more substantial figure than the older textbook caricature but as less than the great president his ratings rehabilitation has sometimes suggested.

Q: What role did Theodore Roosevelt play in shaping the 1898 war?

Theodore Roosevelt, then Assistant Secretary of the Navy under John D. Long, played a substantial role in shaping both the readiness of American naval forces and the eventual scope of the conflict. Roosevelt had taken office on April 19, 1897, and immediately began pressing for expanded naval readiness, increased coal stockpiles at the Asiatic Squadron’s Hong Kong base, and the preparation of contingency plans for offensive operations against Spanish possessions in the event of war. The most consequential single act was the February 25, 1898 telegram to Commodore Dewey, sent during Long’s afternoon absence and ordering Dewey to keep his squadron fueled and ready and to begin offensive operations against the Philippines in the event of war. Long returned to find the telegram already sent; he was annoyed but did not countermand it, partly because the substance was defensible and partly because reversing his subordinate publicly would have created a political crisis. Roosevelt also lobbied congressmen, wrote to Lodge and other senators urging intervention, and after resigning his Navy position in early May 1898 organized the First Volunteer Cavalry (the Rough Riders) and participated in the Cuban campaign personally. The political dividend was the New York governorship in 1898 and the vice presidential nomination in 1900, putting him in position for the September 1901 succession.

Q: How did the war change the American military establishment?

The Spanish-American War exposed substantial deficiencies in the American military establishment and produced the most important reform of the war and naval departments before the National Security Act of 1947. The army of 1898, optimized for frontier constabulary and Indian-wars operations, struggled with the logistical demands of overseas force projection: the embarkation at Tampa was chaotic, the medical and supply services failed at multiple points, and disease casualties exceeded combat casualties by a factor of five. Secretary of War Russell Alger resigned in 1899 under criticism. His successor, Elihu Root, undertook the most substantial reform of the army between 1898 and 1947, creating the Army War College in 1901, establishing a General Staff system in 1903, and producing the Root Reforms that systematized officer education, command relationships, and the relationship between the regular army and the National Guard. The naval establishment, having performed substantially better in 1898 than the army, also expanded under the post-war program of capital ship construction that produced the Great White Fleet of 1907 to 1909 and established the United States as a first-rank naval power.

Q: What was the role of Mark Hanna in McKinley’s 1898 decisions?

Mark Hanna, the Cleveland industrialist who had been McKinley’s principal political adviser since the early 1890s and who had managed both McKinley’s 1896 presidential campaign and his subsequent congressional and patronage operations, played an important behind-the-scenes role in the 1898 decision arc. Hanna was a conservative business Republican aligned with McKinley’s diplomatic-restraint preference; through February and most of March 1898, Hanna lobbied congressional Republicans to support continued diplomacy and warned against the political damage that war might produce on business interests. The Proctor speech of March 17 substantially changed Hanna’s calculation, as it changed the calculations of the conservative business Republican wing more broadly: once the conservative business case for restraint had been undercut by Proctor’s documentary report, Hanna’s continued opposition to intervention would have isolated him from his political base. Hanna shifted to supporting the war message in early April, and his support helped secure the Senate Republican votes for the April 19 resolution. Hanna’s letters from this period, preserved in the Hanna papers at the Western Reserve Historical Society, show a man pulled reluctantly into supporting a war he had initially opposed, mirroring the trajectory of his principal.

Q: How did the anti-imperialist movement respond to the McKinley war?

The Anti-Imperialist League, founded in Boston in November 1898 in response to the emerging acquisition of the Philippines, became the most substantial organized opposition to the McKinley territorial expansion. The League’s membership included former president Grover Cleveland, Andrew Carnegie (who offered to purchase the Philippines from the United States personally for twenty million dollars to grant them independence), Mark Twain, William James, Carl Schurz, and a substantial portion of the older New England elite. The League’s arguments were constitutional (permanent acquisition of territories with non-white populations was incompatible with the American republican framework), economic (the costs of imperial governance would exceed the benefits), and moral (the suppression of Filipino independence reproduced the very Spanish methods the United States had gone to war to oppose). The League lost the 1899 ratification fight by a single vote and lost the 1900 election decisively, but its arguments shaped subsequent American political discourse about empire and helped to constrain further territorial acquisition after 1898. The League’s eventual decline was less about defeat than about the absorption of its concerns into other Progressive Era reform movements.

Q: What is the most important single document for understanding McKinley’s April 1898 decision?

The single most important document is the Woodford cable of April 10, 1898, in which the American minister in Madrid reported the Spanish concession of the previous day and pleaded with the administration to give the new diplomatic framework time to work. The cable, preserved in the State Department archives and reprinted in the Foreign Relations of the United States volumes for 1898, establishes that the diplomatic track had effectively succeeded forty-eight hours before McKinley sent the war message, that Woodford himself believed peace on American terms was achievable, and that the president received this information in time to alter his message and chose not to alter it. No other single document captures the gap between the diplomatic outcome and the political action with the same precision. The cable is what makes the conventional teaching narrative impossible to sustain: if McKinley had received this cable and acted differently, no war would have occurred on April 21; he received it and acted as if it had not arrived, which means the cable’s content was not the operative factor in the April 11 decision. The structural argument of this article rests substantially on the implication of that single document.
