Mexico (1821–24)

Mexico (1821–24) covers the immediate post-independence period following the collapse of the Viceroyalty of New Spain and the transition from colonial rule to the First Mexican Empire and then to a federal republic. This era involved leaders such as Agustín de Iturbide, clerical and military actors from the Conspiracy of 1820, debates in the Constituent Congress (Mexico) and interactions with foreign actors including Spain, the United States, and the Mexican Empire (First)'s European houses. Political experiments, social reordering, and territorial negotiations set precedents for the later First Mexican Republic.

Background and Independence Movement

The independence movement culminated from pressures involving the Peninsular War, the return of Ferdinand VII of Spain and liberal revolutions like the Trienio Liberal, linking provincial juntas, insurgent leaders and royalist officers. Key insurgents and actors included Miguel Hidalgo y Costilla, José María Morelos, Vicente Guerrero, Juan Aldama, José Mariano Jiménez, and later royalist-turned-independence figures such as Agustín de Iturbide and Guadalupe Victoria. Military campaigns and proclamations—e.g., the Plan of Iguala and the Treaty of Córdoba—brought together factions from New Spain's intendancies, clergy allied to Roman Catholicism, and elites from Guadalajara, Puebla, Vera Cruz, and Mexico City. The collapse of the Viceroyalty of New Spain and the abdication pressures on colonial authorities followed the influence of Manuel de Iturbide’s relatives and contacts with foreign powers like the United Kingdom and brokers connected to the Spanish Constitution of 1812.

Provisional Government and Political Transition

After the declaration of independence, the provisional authorities negotiated authority among military leaders, ecclesiastical figures, and local elites. The Army of the Three Guarantees under Agustín de Iturbide and Vicente Guerrero enforced the Plan of Iguala’s guarantees of Union of the provinces, Catholic unity, and Independence. Interim bodies such as the Provisional Governing Junta (Mexico) and councils in Orizaba and Veracruz mediated appointments like the Regency of the Mexican Empire and contested municipal councils in Puebla de los Ángeles and Querétaro. Debates between centralists influenced by the Spanish Cortes and federalists inspired by the United States of America emerged in provincial capitals and military garrisons.

First Mexican Empire and Agustín de Iturbide

The proclamation of Agustín de Iturbide as Emperor followed acclamation in Mexico City and formal endorsement by the Congress of the Empire. The First Mexican Empire attempted monarchical structures with a Regency and court influenced by Spanish imperial institutions and contemporary European monarchies such as the House of Bourbon and the House of Habsburg. Iturbide’s coronation, financial strains with ministers like José Manuel de Herrera, and conflicts with military leaders including Antonio López de Santa Anna produced political crises. Regional uprisings in Oaxaca, Guerrero, and Zacatecas and episodes like the Plan of Casa Mata questioned the legitimacy of the Empire and pressured Iturbide to abdicate and submit to the Constituent Congress (Mexico).

Republican Constituent Congress and Constitution of 1824

Following Iturbide’s abdication, the Congress of Chilpancingo-style representative debates reconvened in a Constituent Congress (Mexico), where federalist delegates from Coahuila y Tejas, Nuevo León, Yucatán, Chiapas, and central provinces argued with centralists from Mexico City and Puebla. Influences included constitutional models from the United States Constitution, the Spanish Constitution of 1812, and the French Charter of 1814 through intellectuals and deputies such as José María Luis Mora, Miguel Ramos Arizpe, and Valentín Gómez Farías. The result was the Constitution of 1824, establishing a federal republic with a separation of branches and a bicameral legislature, shaping institutions like the Supreme Court of Justice of the Nation and state congresses across provinces formerly part of New Spain.

Social and Economic Conditions

Social hierarchies from the colonial period persisted, involving peninsular elites, criollos, mestizos, indigenous communities, and Afro-Mexican populations in regions such as Veracruz, Tabasco, and Oaxaca. Land tenure disputes implicated hacendados, communal holdings of communities like the Yaqui, and ecclesiastical properties held by Roman Catholic Church institutions and orders including the Franciscans and Dominicans. Fiscal crises followed the loss of royal revenue streams, affecting customs at Veracruz and silver production in Zacatecas and Guanajuato, while trade relationships with the United Kingdom, United States, and Caribbean markets shifted patterns of export for silver, cochineal, and agricultural staples. Social unrest and banditry occurred as military discharges and veteran settlements met rural poverty, involving figures such as Vicente Guerrero and local caciques.

Foreign Relations and Territorial Issues

Diplomacy centered on recognition by Spain, which refused immediate acceptance, and by powers such as the United Kingdom, which sought commercial treaties, and the United States, which observed border dynamics in Louisiana Purchase-adjacent zones and Texas. Negotiations over boundaries included disputes in Alta California, Nuevo México, and the Gulf coast, while foreign adventurers and filibusters eyed territories like Texas and ports such as Cozumel. The crown pensions and claims from Spanish officials, indemnities to British merchants, and offers to European royal houses, including approaches toward the House of Bourbon and members of the House of Saxe-Coburg and Gotha, complicated recognition. The Treaty framework and proclamations about sovereignty influenced later episodes like the Adams–Onís Treaty echoes and Anglo-Mexican commercial relations.

Legacy and Historical Assessment

The 1821–24 interval established foundational institutions, political language, and territorial outlines that informed the later First Mexican Republic and conflicts such as the Texas Revolution and the Mexican–American War. Historians debate Iturbide’s role relative to insurgents like Miguel Hidalgo and José María Morelos, and analyze the Constituent Congress’s synthesis of federalist and centralist traditions shaped by figures like Miguel Ramos Arizpe and José María Liceaga. Legacies include contested landholding regimes, church-state relations mediated by clergy such as Lucas Alamán-era conservatives, and constitutional precedents influencing mid-19th century reforms under leaders like Benito Juárez and Antonio López de Santa Anna. The period remains pivotal for understanding the transition from the Spanish Empire to a sovereign Mexican polity in the nineteenth century.
