Mexican Empire (1821–1823) The Mexican Empire (1821–1823) was the short-lived independent monarchy that emerged after the collapse of Viceroyalty of New Spain and the end of the Mexican War of Independence. Led by Agustín de Iturbide as Emperor, the regime attempted to reconcile factions including former royalists, insurgents, clergy, and colonial elites while navigating relations with the Spanish Empire, the United Kingdom, and the United States. Political tensions between monarchists, federalists, and centralists culminated in revolts that produced the empire's dissolution and the establishment of the First Mexican Republic.

Background and Independence Movement

The collapse of the Viceroyalty of New Spain followed decades of conflict involving figures such as Miguel Hidalgo y Costilla, José María Morelos, Vicente Guerrero, and Guadalupe Victoria, who led uprisings against the Bourbon Reforms and the Spanish Cortes of Cádiz. The 1810–1821 Mexican War of Independence saw battles like the Siege of Cuautla and the Battle of Calderón Bridge, alongside shifting loyalties among creoles, peninsulares, and indigenous communities. The 1820 liberal revolution in Spain led by Rafael del Riego weakened royal authority and prompted negotiations culminating in the Plan of Iguala and the Treaty of Córdoba that established terms for independence and proposed a constitutional monarchy under a European prince. Key political actors included Juan O'Donojú, the last royalist jefe político, and conservative clerical elites represented by the Catholic Church in Mexico and bishops such as Juan Francisco de Güemes.

Establishment of the Empire

The Plan of Iguala articulated the "Three Guarantees"—religion, independence, and unity—and formed the Army of the Three Guarantees under Agustín de Iturbide and Vicente Guerrero. The entry of the Army into Mexico City on 27 September 1821 culminated in the Treaty of Córdoba, negotiated by Juan O'Donojú and ratified by Iturbide's faction, which formalized independence and sought a monarch from the House of Bourbon. When no European prince accepted the throne, Mexico's constituent congress debates involved figures like Lucas Alamán, Nicolás Bravo, and Miguel Ramos Arizpe, eventually leading to the proclamation of Iturbide as Emperor in May 1822 under the title Agustín I. Controversies erupted around the Solemn Coronation of Agustín I, the composition of the Provisional Governing Junta, and the legal validity of Iturbide's assumption of the crown.

Government and Administration

The imperial structure combined monarchical prerogatives with institutions drawn from colonial administration. Iturbide's regime appointed ministers such as Lucas Alamán and relied on the Imperial Guard and the Army of the Three Guarantees for enforcement. The Constituent Congress clashed with the emperor over powers, taxation, and appointments, invoking legal traditions from the Laws of the Indies and the Spanish legal system. Provincial governance involved intendancies and alcaldías whose elites included criollo landowners, military caudillos, and ecclesiastical authorities; notable provincial actors included Antonio López de Santa Anna and Nicolás Bravo. Debates over centralization versus provincial autonomy pitted centralist advisers against federalist deputies like Miguel Ramos Arizpe and Pablo de Gutiérrez.

Economy and Society

Post-independence Mexico inherited fiscal strains from wartime expenditure, disrupted silver production in regions such as Zacatecas and Guanajuato, and imperial debts owed to Spanish bondholders and merchants in Seville and Cadiz. Land tenure issues involved hacendados, indigenous communal lands governed by cabildos, and ecclesiastical properties controlled by orders such as the Jesuits and Franciscans. Trade shifts affected ports including Veracruz and Acapulco, while attempts to stabilize currency referenced colonial mints like the Mexico City Mint. Social divisions were apparent among peninsulares, criollos, mestizos, indigenous communities such as the Yaqui and Tarahumara, freed Afro-Mexican populations in regions like Xalapa, and clergy privileges under the Catholic Church in Mexico.

Foreign Relations and Recognition

The empire sought recognition from European powers and the United States; diplomatic engagement involved envoys and naval visits by representatives of the United Kingdom of Great Britain and Ireland and negotiations with ministers such as Edward Thornton and Joel Roberts Poinsett. Spain under the restored Ferdinand VII of Spain refused immediate recognition, maintaining hopes of reconquest and backing royalist émigrés. Interactions with the Holy See and the Papal States concerned the role of the Catholic Church and ecclesiastical appointments. Commercial treaties and concerns over the Monroe Doctrine linked Mexican diplomacy to broader Atlantic geopolitics involving France, Portugal, and the Russian Empire.

Opposition, Federalist Reaction, and Collapse

Opposition coalesced in provinces where federalist leaders like Vicente Guerrero, Antonio López de Santa Anna, and Nicolás Bravo opposed imperial centralization and fiscal exactions. The 1822 dissolution of the Constituent Congress by imperial decree and the imposition of extraordinary levies provoked military pronunciamientos including the Plan of Casa Mata proclaimed by Santa Anna and Guerrero. Mexico City politics saw popular unrest, clerical pushback, and republican agitation led by figures such as Leona Vicario and José María Luis Mora. Facing loss of military cohesion and international isolation, Iturbide abdicated on 19 March 1823 and went into exile; subsequent events included the convening of a new congress that abolished the monarchy and convened a constituent assembly for republican governance.

Legacy and Succession

The fall of the empire ushered in the First Mexican Republic and set precedents for Mexican political culture: competition between centralists and federalists, the prominence of military caudillos like Santa Anna, and debates over church-state relations that culminated in later conflicts such as the Reform War. Iturbide's brief reign influenced later monarchist projects including the Second Mexican Empire under Maximilian I of Mexico and shaped conservative thought represented by Lucas Alamán and liberal reforms championed by Benito Juárez. Economic patterns, land tenure disputes, and provincial cleavages that deepened during the imperial period continued to affect 19th-century Mexican development and diplomacy with powers like the United States and European colonial empires.
