Iturbide's Empire was a short-lived monarchy that followed the Mexican War of Independence and attempted to establish a constitutional monarchy in the territory of the former Viceroyalty of New Spain. Centered in Mexico City, the regime emerged from alliances among conservative criollo elites, royalist officers, and insurgent leaders, but faced immediate diplomatic isolation, fiscal crisis, and regional dissent which led to its rapid collapse within a year.
Agustín de Iturbide rose from service in the Spanish Army and participation in counterinsurgency during the Mexican War of Independence to prominence through the proclamation of the Plan of Iguala alongside Vicente Guerrero and negotiation with royalist leaders such as Juan O'Donojú. The Plan of Iguala promised the three guarantees of Catholicism, Independence, and Union, seeking to reconcile factions including former insurgents influenced by figures like Miguel Hidalgo y Costilla, José María Morelos, and Guadalupe Victoria with conservative elites tied to institutions such as the Catholic Church and the Audiencia of Mexico. The collapse of Spanish authority after the Napoleonic Wars and the 1820 Liberal Triennium in Spain destabilized colonial administration and encouraged plans for sovereignty modeled by the Philippine Revolution and independence movements in South America led by Simón Bolívar and José de San Martín. Iturbide's coalition leveraged support from regional military commanders in provinces like Veracruz, Puebla, and Nuevo León and secured recognition from the outgoing Spanish representative Juan O'Donojú through the Treaty of Córdoba framework.
Following the proclamation of independence on 24 September 1821, the newly independent elites convened to determine a form of state, with debates among proponents of a constitutional monarchy inspired by the Constitution of Cádiz (1812), advocates of a republic influenced by Thomas Jefferson and Alexander Hamilton-era federalism, and traditionalists favoring monarchical continuity like in the Kingdom of Portugal. Pressure from military officers, merchants of Guatemala and Havana, and clergy resulted in the offer of an hereditary crown to a European monarch; when that failed, the congress proclaimed Agustín de Iturbide emperor. The coronation ceremony in Mexico City on 21 July 1822 drew ecclesiastical participation from clerics aligned with the Archbishopric of Mexico and drew comparisons with imperial ceremonies of Napoleon Bonaparte and the Habsburg Monarchy.
Emperor Agustín's administration attempted to construct institutions by blending elements from the Cortes of Cádiz, Spanish colonial practices, and models from contemporary European monarchies such as the United Kingdom and the Kingdom of France. Iturbide appointed ministers and trusted royalist officers including figures tied to the Bourbon administrative legacy and relied on conservative landholders in regions like Puebla and Querétaro. Fiscal policy struggled under obligations to pay soldiers and creditors in silver coin, while absence of recognition from powers including the United Kingdom of Great Britain and Ireland, the United States of America, and the Spanish Empire compounded trade disruptions in ports such as Veracruz and Acapulco. Efforts to promulgate a Mexican Constitution were stymied by tensions between centralists influenced by thinkers who read Juan Bautista Alberdi and emergent federalists allied with regional caudillos like Antonio López de Santa Anna. Administrative appointments often favored military figures from the Army of the Three Guarantees, producing rivalries with civilian leaders and institutions such as the Supreme Court of Justice of the Nation analogues in the interim structures.
Opposition coalesced around diverse leaders including liberal deputies, republican officers, and regional elites in provinces like Yucatán, Oaxaca, and Chihuahua who objected to perceived authoritarianism and financial mismanagement. Prominent opponents included Guadalupe Victoria, Vicente Guerrero (who initially allied with Iturbide), and provincial caudillos whose grievances echoed those of Liberal constitutionalists who looked to the example of the United States Constitution and the revolutionary precedents of Haiti and Gran Colombia. The promulgation of suspensions of the constituent congress and the arrest of deputies heightened tensions, prompting rebellions led by figures such as Antonio López de Santa Anna in Vera Cruz and the issuance of proclamations like the Plan of Casa Mata by Guadalupe Victoria and Vicente Guerrero. Military defections, economic blockades, and declining support among the Clergy and urban guilds in Mexico City accelerated the empire’s disintegration.
Facing unified military opposition and political isolation, Agustín de Iturbide abdicated in March 1823 and agreed to exile under terms negotiated by the remaining authorities, with exile destinations contemplated among Europe and ports like Livorno and Bordeaux discussed by contemporaries familiar with Royalist expatriate networks. Despite promises, Iturbide’s return to Mexican territory in 1824—landing on Papagayo Beach—led to his arrest under decrees by the provisional Congress of the Union; he was tried by military tribunal and executed by firing squad in Padilla, Tamaulipas. His death intersected with ongoing regional conflicts involving exiles and mercenary networks that included veterans of the Peninsular War and former officers connected to the Royalist Army.
Historians debate the empire’s legacy, connecting it to the early republican trajectory embodied by presidents like Guadalupe Victoria, Vicente Guerrero (later president), and Valentín Gómez Farías, and to later centralist regimes culminating in leaders such as Antonio López de Santa Anna and Porfirio Díaz. Scholarly perspectives range from viewing the episode as a pragmatic short-term stabilization akin to other postcolonial experiments in Latin America—parallel to the formations of Gran Colombia, the United Provinces of Central America, and the Empire of Brazil—to critiquing it as a missed opportunity for durable constitutionalism that might have avoided subsequent decades of caudillismo, foreign interventions like the Mexican–American War, and economic dependency shaped by trade with the United Kingdom and the United States. Cultural memory preserves Iturbide in monuments, historiography, and debates over national symbols including the Flag of Mexico and the Coat of arms of Mexico, while archival collections in institutions such as the Archivo General de la Nación (Mexico) and libraries at the Universidad Nacional Autónoma de México continue to inform reassessments of the empire’s short but consequential existence.
