Plan of San Luis Potosí

Plan of San Luis Potosí.

The Plan of San Luis Potosí was a political proclamation issued by Francisco I. Madero that called for armed revolt against Porfirio Díaz and repudiated the results of the 1910 Mexican general election. It served as a catalyst for the Mexican Revolution and influenced figures such as Emiliano Zapata, Pancho Villa, Álvaro Obregón, Venustiano Carranza, and organizations including the Constitutionalists, Liberals (Mexico), and regional jefes across Chihuahua, Morelos, and Coahuila. Its text invoked principles from precedents like the Plan of Ayala, the Plan of San Luis Potosí (1910)—the proclamation itself—and broader currents drawn from the Liberal Reform, the Porfiriato, and international observers in United States cities such as San Antonio, Texas and El Paso, Texas.

Background

In 1910 the incumbent president Porfirio Díaz faced opposition from Francisco I. Madero, an anti-reelectionist leader from the Instituto Científico y Literario de Toluca milieu and son of a merchant family with ties to Tamaulipas and Coahuila. Madero published his ideas in the La sucesión presidencial en 1910 and organized the Anti-reelectionist Party against Díaz's Porfiriato regime, clashing with elites in Puebla, Jalisco, Veracruz, and Sinaloa. After Madero's arrest in San Luis Potosí and exile to San Antonio, Texas, he drafted a proclamation invoking legal doctrines familiar from the Constitution of 1857, the Plan of Ayala critics, and appeals to liberal elites in Mexico City, Guadalajara, Monterrey, and abroad in Buenos Aires and New York City. Key supporters included Ricardo Flores Magón, Camilo Arriaga, Jesús González Ortega, and agrarian leaders who later allied with Emiliano Zapata and Luis Cabrera Lobato.

Text and Provisions

The proclamation declared the 1910 Mexican general election null and void, proclaimed Madero provisional head of a revolutionary movement, and set 20 November 1910 as the date for insurrection. Its language drew upon earlier plans such as the Plan of Iguala in rhetorical structure while differing in demands from the Plan of San Luis Potosí (1910)'s later agrarian extensions like the Plan of Ayala from 1911. Provisions called for the ousting of Díaz, the restoration of electoral rights under liberal doctrines championed by Benito Juárez, and promises of political reform that appealed to middle-class reformers in Zacatecas, Durango, and Aguascalientes. The text combined legalist rhetoric from the Constitution of 1857 with revolutionary exhortation that galvanized federales deserters, rural militias in Chihuahua and Hidalgo, and urban labor groups affiliated with the Casa del Obrero Mundial and Casa del Obrero Mundial's contemporaries.

Political and Social Impact

The proclamation transformed regional grievances into a national uprising, prompting insurrections led by Emiliano Zapata in Morelos, Pancho Villa in Chihuahua, and constitutionalist officers such as Venustiano Carranza in Coahuila. It precipitated defections within the Federal Army and influenced conservative politicians like Manuel González and reformists such as Francisco Murguía and Álvaro Obregón. Urban intellectuals in Mexico City, journalists from El Imparcial, and exile networks in Los Angeles and San Antonio, Texas disseminated the plan, while international actors including the United States Department of State and investors in British and French banks monitored developments in San Luis Potosí and Puebla. Social movements—land reform advocates, indigenous communities in Oaxaca, miners in Guanajuato, and railroad workers—interpreted the plan through local demands, leading to alliances and tensions with leaders such as Ricardo Flores Magón and Amador Salazar.

Role in the Mexican Revolution

As the opening salvo of the Mexican Revolution, the proclamation catalyzed campaigns including the Battle of Ciudad Juárez (1911), the fall of Porfirio Díaz and the Treaty of Ciudad Juárez (1911), and the eventual presidency of Francisco I. Madero. It set in motion rivalries that produced counter-plans like the Plan of Ayala led by Emiliano Zapata, and later conflicts culminating in the Decena Trágica, the assassination of Madero, and the rise of leaders such as Victoriano Huerta and Venustiano Carranza. Military figures including Pascual Orozco, Emilio Madero, Tomás Urbina, and José María Pino Suárez engaged in campaigns across Coahuila, Zacatecas, and Chiapas, shaping the trajectory of constitutionalist and conventionalist factions at the Constitutional Convention (1917).

Legacy and Historiography

Historians have debated whether the proclamation was principally a liberal constitutionalist manifesto or a revolutionary manifesto that enabled social radicalism. Scholarship by Alan Knight, Samuel Brunk, John Womack, Turner, Adolfo Gilly, Frank McLynn, and Jorge Ayala situates the plan within longer-term processes from the Reform War to the Porfiriato. Archival sources in the Archivo General de la Nación (Mexico), newspapers like El País for comparative studies, and collections in Bancroft Library and Library of Congress inform debates over authorship, intent, and reception. The proclamation remains a touchstone in discussions of land reform, democratic transition, and revolutionary legitimacy in Mexican studies, cited in analyses of the Mexican Constitution of 1917, agrarian law, and twentieth-century politics led by figures like Lázaro Cárdenas and Plutarco Elías Calles.
