Mexico (1821–1864) The period from 1821 to 1864 covers Mexico’s transition from the consummation of Mexican War of Independence to the establishment of the Second Mexican Empire under Maximilian I of Mexico. It saw rapid changes involving monarchical experiment, republican constitutions, regional rebellions, wars with Spain, United States, and internal struggles between liberal and conservative elites. Key actors include military caudillos, clerical hierarchies, commercial interests, and foreign powers such as France under Napoleon III.

Independence and Establishment of the First Mexican Empire (1821–1823)

The consummation of independence followed the Plan of Iguala and the Treaty of Córdoba, negotiated by royalist turncoat Agustín de Iturbide and insurgent leaders including Vicente Guerrero and supporters of José María Morelos. The proclamation of the First Mexican Empire placed Iturbide as Emperor Agustín I, provoking tensions among proponents of Monterrey, Guadalajara, Veracruz, Puebla de Zaragoza, and oligarchs tied to Real Hacienda networks. Diplomatic recognition efforts involved envoys to United Kingdom of Great Britain and Ireland, Holy See, and former colonial authorities in New Spain; meanwhile political groupings such as the York Rite Masons and Scottish Rite Masons aligned with liberal and conservative factions. Provincial juntas and caudillos including Nicolás Bravo, Pedro Celestino Negrete, Guadalupe Victoria, and Lucas Alamán contested royalist legacies until the abdication and exile of Iturbide after the Plan of Casa Mata.

Early Republican Turmoil and Federalist-Centralist Conflicts (1823–1835)

The proclamation of the United Mexican States inaugurated debates over the 1824 Constitution of Mexico patronized by politicians like Valentín Gómez Farías and Miguel Ramos Arizpe while military figures such as Antonio López de Santa Anna maneuvered between federalist and centralist positions. Regional tensions manifested in uprisings in Yucatán, Veracruz, Oaxaca, and Texas, and disputes over debts with creditors in Cadiz and financiers in Boston. Political clubs, newspapers tied to liberal and conservative interests, and the role of bishops such as Juan de la Luz Enríquez influenced debates about secularization, military prerogatives, and fiscal policy. Constitutional crises produced rotating presidencies—Guadalupe Victoria, Vicente Guerrero, Anastasio Bustamante—and frequent pronunciamientos by generals like Manuel Gómez Pedraza.

Centralist Republic and the Texas Revolution (1835–1846)

The shift toward centralism under the Siete Leyes and the presidency of Antonio López de Santa Anna heightened provincial alienation in Coahuila y Tejas and Nuevo León, contributing directly to the Texas Revolution and battles such as the Siege of Bexar, Battle of the Alamo, Battle of San Jacinto, and the capture of Santa Anna at Battle of San Jacinto. The loss of Texas and subsequent proclamations of the Republic of Texas involved diplomats like James Pinckney Henderson and debates in the United States Congress. Centralist policy also provoked revolts in Tabasco, Sinaloa, and the Yucatán with leaders such as Miguel Barbachano and Antonio López de Santa Anna alternately returning from exile to reclaim authority. International commerce and port centers including Tampico and Campeche were affected by privateers and naval actions tied to disputes with Spain and Great Britain.

Mexican–American War and Its Aftermath (1846–1848)

The Mexican–American War saw engagements at Battle of Palo Alto, Battle of Resaca de la Palma, Siege of Veracruz (1847), Battle of Cerro Gordo, Battle of Buena Vista, Battle of Contreras, Battle of Churubusco, and the Battle for Mexico City culminating in occupation by Winfield Scott and Zachary Taylor forces. Diplomatic resolution came with the Treaty of Guadalupe Hidalgo, ceding vast territories including Alta California, New Mexico, and Texas boundaries, while provoking domestic critiques from politicians like Lucas Alamán and Mariano Paredes y Arrillaga. The war destabilized administrations such as those of Mariano Arista, Pedro María Anaya, and Manuel de la Peña y Peña and empowered military elites; veterans like Antonio López de Santa Anna re-emerged amid economic crises involving the National Treasury and custom revenues from Veracruz.

Reform, Conservative Reaction, and the Rise of Santa Anna (1848–1855)

Postwar reconstruction involved fiscal austerity debates, railroad proposals marshaled by technocrats allied to Lucas Alamán, and conflicts over ecclesiastical privileges led by figures such as Juan Nepomuceno Almonte and archbishops in Mexico City. Conservative consolidation relied on alliances between landowners, clerical hierarchies including Mexican bishops, and military strongmen; the return of Santa Anna culminated in his virtual dictatorship after pronunciamientos and the suppression of rebellions like those of Vicente Guerrero supporters. Liberal leaders including Benito Juárez and Melchor Ocampo campaigned for secular reforms while opponents such as Miguel Miramón and Félix Zuloaga organized conservative networks. Foreign capital proposals invited investors from Great Britain and France under Louis Philippe, while the national debt discussions involved financiers in London and New York City.

La Reforma and the Liberal Reforms (1855–1861)

The liberal revolution of the Plan of Ayutla brought down Santa Anna and elevated reformers such as Juan Álvarez, Ignacio Comonfort, Benito Juárez, and Miguel Lerdo de Tejada. The promulgation of the Juárez Law, the Ley Lerdo, and the Constitution of 1857 curtailed corporate privileges of Roman Catholic Church and militia institutions, provoking mobilization by conservative clergy and generals. Intellectuals and jurists like Justo Sierra and Ponciano Arriaga debated civic codes while provincial leaders in Jalisco, Puebla, and Chihuahua reacted variably. International observers from Paris and London monitored reforms affecting property regimes and civil institutions; tensions over enforcement precipitated episodes such as the Liberal-Conservative schism and prompted exiles of conservative notables to Havana and Madrid.

The Reform War and the Rise of the Second Mexican Empire (1857–1864)

Open civil conflict erupted in the Reform War between constitutionalist liberals under Benito Juárez and conservative forces led by Miguel Miramón and Félix Zuloaga, producing battles around Puebla, Toluca, and Querétaro. Exhaustion and suspension of foreign debt service under Juárez invited intervention by France under Napoleon III, Spain, and United Kingdom of Great Britain and Ireland via the Tripartite Expedition (1861–1862). While British and Spanish forces negotiated settlements, French ambitions—backed by conservatives like Lucas Alamán's followers and clerical circles—sought a monarchical solution culminating in the invitation to Maximilian of Habsburg and the proclamation of the Second Mexican Empire. By 1864 Maximilian arrived in Veracruz with imperial supporters including José María Lacunza and elements of the Mexican Army; liberal resistance persisted under Juárez and generals such as Santos Degollado and Vicente Riva Palacio, ensuring that the imperial project remained contested.
