Through Napoleon and Peninsulares

The establishment of a monarchy was the initial goal for an independent Mexico, as outlined in the Plan of Iguala, a political document drafted by Iturbide that unified the forces fighting for independence from Spain. Following the signing of the Treaty of Córdoba by the last Spanish viceroy in September 1821, the plan for a Mexican monarchy advanced. Iturbide's popularity reached its peak on May 18, 1822, when public demonstrations called for him to become emperor in the absence of a European royal willing to assume the throne. The Mexican Congress approved the proposal, and Iturbide was crowned in July 1822.

The empire's brief existence was marked by challenges, including disputes over its legitimacy, conflicts between the Congress and the emperor, and a bankrupt national treasury. In October 1822, Iturbide dissolved Congress and replaced it with the National Institutional Junta, composed of his supporters. However, by December of the same year, he began to lose the support of the Mexican Army, which rebelled in favor of restoring the Congress and its democratic powers. Unable to suppress the revolt, Iturbide reconvened the Congress in March 1823 and offered his abdication. Power was then transferred to a republican provisional government of 1823-1824, which abolished the monarchy and established the First Mexican Republic.

Background

The Spanish Empire disintegrated in the wake of Napoleon's invasion of Spain and the overthrow of the Spanish Bourbons in 1808. Throughout Spain and its viceroyalties there was a widespread refusal to recognize Napoleon's brother Joseph I as the new French-backed king of Spain. In New Spain cleric Miguel Hidalgo y Costilla, who had long been part of a circle of intellectuals who sought to reform the colonial system, triggered the Mexican War of Independence in 1810, a decade of warfare between insurgents for independence from Spain and royalists seeking to maintain the existing colonial order. The insurgency was initially led by Hidalgo, who was captured and executed in 1811, then succeeded by Father José María Morelos, who was likewise captured and executed in 1815. Remaining insurgents, including Vicente Guerrero, waged guerrilla warfare in the countryside of southern Mexico. Agustín de Iturbide was a Mexican officer in the Spanish army, a member of the Mexican elite loyal to Spain. When Liberals in Spain seized power in 1820, re-established the Spanish Constitution of 1812, forcing limits on the power of Ferdinand VII of Spain and curtailing privileges of established elites and institutions, Mexican elites saw their interests threatened. In view of this, Iturbide sought an alliance with Mexican insurgents, drawing up the Plan of Iguala and gaining the support of insurgent leader Vicente Guerrero and others. They created the Army of the Three Guarantees, which brought about Mexican independence from Spain in September 1821.

The newly constituted movement involved three principles, or "guarantees": that Mexico would be an independent constitutional monarchy governed by a Spanish prince; that Americanos, that is all Mexicans regardless of ethnic category and those born in Spain would henceforth enjoy equal rights and privileges; and that the Roman Catholic Church would retain its privileges and position as the official and exclusive religion of the land. These Three Guarantees formed the core of the Plan of Iguala, the blueprint which, by combining the goal of independence and a constitution with the preservation of Catholic monarchy and Roman Catholicism, brought together all Mexican factions. Under the 24 February 1821 Plan of Iguala, to which most of the provinces subscribed, the Mexican Congress established a regency council which was headed by Iturbide.

Viceroy Juan O'Donojú acceded to the Mexican insurgents' demands, having no other option because he lacked independent resources. He signed the Treaty of Córdoba on 24 August 1821. The Mexican Congress intended to establish a personal union, similar to the arrangement now found among the Commonwealth realms; Ferdinand would remain King of Spain and separately take the throne of a new Mexican kingdom, independent of Spain but sharing a monarch. If the Spanish king refused the position, the plan provided for another member of the House of Bourbon to accede to the Mexican throne. Commissioners from Mexico were sent to Spain to offer the Mexican throne to a Spanish royal, but the Spanish state refused to recognize Mexico's independence and would not allow any other Spanish prince to accept the throne.
