Plan of Casa Mata was a short but decisive pronunciamiento issued in early 1823 that precipitated the end of the First Mexican Empire and the abdication of Agustín de Iturbide. The proclamation united provincial military and political leaders in opposition to imperial centralism, connecting events in Vera Cruz, Guadalajara, Jalisco, Chihuahua, Oaxaca, and Puebla de Zaragoza with insurgent sentiment in Zacatecas. Its success reshaped post-independence trajectories, influencing later actors such as Antonio López de Santa Anna, Guadalupe Victoria, Vicente Guerrero, and foreign observers in Washington, D.C. and London.

Background

The proclamation emerged amid tensions following the Mexican War of Independence and the 1822 proclamation of Agustín de Iturbide as emperor after the Plan of Iguala and the Treaty of Córdoba. Regional caudillos and civic elites in provinces like Jalisco, Yucatán, Nuevo León, and San Luis Potosí reacted against perceived autocracy tied to the imperial court in Mexico City and to economic pressures interacting with trade with United States merchants and Spanish Empire loyalists. Previous pronunciamientos such as the Plan of Veracruz (1822) and the revolt led by Antonio López de Santa Anna had already destabilized the imperial regime; the Casa Mata movement drew on networks involving officers from the Royalist army (Spanish) who had joined independence, veterans of the Siege of Cuautla, and political figures including Nicolás Bravo and Pedro Celestino Negrete.

Drafting and Signatories

Drafting occurred in the vicinity of Acapulco at the hacienda known as Casa Mata, with conspirators coordinating through intermediaries between provincial capitals like Guadalajara, Jalisco and ports including Veracruz (city). Principal signatories included military leaders such as Antonio López de Santa Anna, Guadalupe Victoria, Vicente Guerrero, Nicolás Bravo, and civil notables like Pedro Celestino Negrete and representatives from Puebla de Zaragoza, Querétaro, and Chiapas. The text repudiated the monarchical claims of Agustín de Iturbide and called for the restoration of representative institutions modeled in part on precedents like the Spanish liberal Triennium and earlier Latin American pronunciamientos from Buenos Aires and Caracas. The coordination involved messengers traveling between garrisons in Vera Cruz, Matamoros, Toluca, and San Luis Potosí who carried sealed proclamations and letters from provincial ayuntamientos.

Political Context and Goals

The Plan aimed to convene a constituent assembly drawn from provincial deputations to decide Mexico's form of rule, echoing the constitutionalist impulses of the Cádiz Cortes and contemporary debates in Lima and Bogotá (formerly Santa Fe de Bogotá). Its authors sought to dismantle centralized imperial prerogatives vested in Iturbide while securing military legitimacy through alliances with figures like Santa Anna and Vicente Guerrero, and obtaining acquiescence from commercial interests in Veracruz (city), Manzanillo, and Cozumel. The document appealed to local elites in Yucatán, Nuevo León, Durango, and Zacatecas by promising provincial representation and the reestablishment of ayuntamientos modeled after those in Seville and Madrid during the late colonial period. Internationally, the Plan signaled to governments in London, Paris, and Washington, D.C. that Mexico sought a republican resolution rather than prolonged monarchical instability.

Military Campaign and Implementation

Military implementation combined negotiated defections and battlefield maneuvers across regional theaters: garrisons at Vera Cruz, Acapulco, Guadalajara, Jalisco, and Veracruz either joined the pronunciamiento or were neutralized. Campaigns featured commanders who had fought in the Mexican War of Independence such as Vicente Guerrero and Guadalupe Victoria, and former royalist officers who shifted allegiances following the Plan of Iguala. Key confrontations and troop movements occurred near strategic nodes including Toluca de Lerdo, Celaya, San Luis Potosí, and coastal approaches at Veracruz (city). Naval officers and port authorities in Acapulco and Veracruz played roles, while diplomatic pressure and internal conspiracies in Mexico City undermined imperial cohesion. Military councils assembling in provincial capitals issued circulars that spread the Plan's authority, prompting local militias organized in towns such as Puebla de Zaragoza and Oaxaca to declare for the constituent call.

Immediate Aftermath

Rapid erosion of support forced Agustín de Iturbide to abdicate; he left Mexico City amid proclamations from the newly convened provincial juntas in Guadalajara, Jalisco, Vera Cruz, and Zacatecas. The collapse of the empire led to the establishment of a provisional executive dominated by figures from the Plan coalition, including Guadalupe Victoria and Pedro Celestino Negrete, and set the stage for elections to a constituent congress influenced by deputies from Querétaro, Guanajuato, Chihuahua, and Durango. The period saw renewed negotiations with foreign creditors in London and commercial agents from United States port cities, while rival factions among Santa Anna, Vicente Guerrero, and conservative landowners contested the shape of the emergent polity.

Legacy and Constitutional Impact

The pronunciamiento accelerated Mexico's transition toward republicanism culminating in the 1824 Constitution of 1824, which created a federal structure drawing on models from the United States and debates circulating in Gran Colombia and Argentina. Long-term legacies include the elevation of leaders such as Guadalupe Victoria to the presidency and repeated interventions by military caudillos like Antonio López de Santa Anna in republican politics. The Plan influenced constitutional discussions in later decades involving states' rights disputes in Texas Revolution contexts and fiscal crises engaging creditors in London and Paris. Historians compare its role to other Latin American constitutional turning points such as the Bolivian Constitutions, the Argentine Constitution of 1853, and the Brazilian Empire's transition debates, situating the Casa Mata event as pivotal in the consolidation of Mexican republican institutions and the reconfiguration of elite power networks across provinces like Jalisco, Yucatán, Nuevo León, and Morelos.
