# Mexican War of Independence

The **Mexican War of Independence** was an armed conflict fought from 1810 to 1821 that resulted in Mexico's liberation from Spanish colonial rule and the establishment of the Mexican Empire. This revolutionary struggle transformed New Spain from a colonial territory into an independent nation, ending three centuries of Spanish dominance in the region and creating the foundation for modern Mexico.

The war began as a popular uprising led by Catholic priests and evolved into a complex political and military campaign that ultimately succeeded through an unlikely alliance between former enemies. The conflict fundamentally reshaped the political landscape of North America and inspired independence movements throughout Latin America.

## Origins and Causes

The roots of Mexican independence lay in growing tensions between different social classes and the impact of European political upheavals. **Criollos** (Mexican-born people of Spanish descent) faced discrimination from **peninsulares** (Spanish-born colonists) who held most high-ranking positions in government and the Catholic Church. This social hierarchy created resentment among educated Mexicans who felt excluded from power despite their wealth and status.

The Napoleonic invasion of Spain in 1808 created a crisis of legitimacy in the colonies. When Napoleon placed his brother Joseph Bonaparte on the Spanish throne, many colonists questioned whether they owed allegiance to the French-controlled government. Economic grievances also fueled discontent, as Spain imposed heavy taxes and trade restrictions that limited colonial prosperity.

Enlightenment ideas about natural rights and self-governance circulated among educated Mexicans, particularly through secret societies and literary clubs. The successful independence of the United States and the Haitian Revolution provided concrete examples that colonial liberation was possible.

## The Hidalgo Phase (1810-1811)

The war began on September 16, 1810, when **Miguel Hidalgo y Costilla**, a Catholic priest in the town of Dolores, issued the famous **Grito de Dolores** (Cry of Dolores). Hidalgo called for the end of Spanish rule, the abolition of slavery, and the return of land to indigenous peoples. His revolutionary army quickly swelled to over 80,000 followers, primarily indigenous people and mestizos seeking social justice.

Hidalgo's forces achieved early victories, capturing major cities including Guanajuato, Valladolid, and Guadalajara. However, the movement lacked military discipline and clear political objectives beyond ending Spanish rule. The rebels committed significant atrocities against Spanish civilians, which alienated potential criollo supporters who feared social revolution more than continued colonial rule.

The Spanish colonial government, led by Viceroy Francisco Javier Venegas, organized a counteroffensive using professional troops and loyalist militias. At the Battle of Calderón Bridge in January 1811, Spanish forces decisively defeated Hidalgo's army. Hidalgo was captured, defrocked by the Catholic Church, and executed in July 1811, marking the end of the first phase of the independence struggle.

## The Morelos Phase (1811-1815)

**José María Morelos**, another Catholic priest and former student of Hidalgo, assumed leadership of the independence movement. Unlike his predecessor, Morelos proved to be a skilled military strategist and political organizer. He transformed the rebellion from a chaotic popular uprising into a more disciplined guerrilla campaign focused on southern Mexico.

Morelos articulated a clearer vision for Mexican independence through documents like the **Sentimientos de la Nación** (Sentiments of the Nation) in 1813. This manifesto called for complete independence from Spain, the establishment of a republican government, the abolition of slavery, and equal rights for all citizens regardless of race. The Congress of Chilpancingo, convened by Morelos in 1813, formally declared Mexican independence and drafted the nation's first constitution.

Under Morelos's leadership, the insurgents controlled significant territory in southern and western Mexico. They established an alternative government, collected taxes, and operated their own postal system. However, Spanish forces gradually gained the upper hand through a combination of military pressure and political reforms that addressed some colonial grievances.

Morelos was captured in December 1815 and executed, dealing a severe blow to the independence movement. By 1816, the rebellion had largely collapsed, with only scattered guerrilla bands continuing to resist Spanish authority.

## The Guerrero and Victoria Phase (1816-1820)

Following Morelos's death, the independence movement entered a period of decline but did not disappear entirely. **Vicente Guerrero** in the south and **Guadalupe Victoria** in Veracruz maintained guerrilla operations against Spanish forces. These leaders kept the revolutionary spirit alive through small-scale attacks and by providing refuge for other independence supporters.

The guerrilla phase was characterized by hit-and-run tactics, ambushes of Spanish supply convoys, and efforts to win over local populations. While these activities did not pose an immediate threat to Spanish control, they prevented the complete pacification of Mexico and maintained pressure on colonial authorities.

Spanish attempts to end the insurgency through military force proved costly and largely ineffective. The rugged terrain of Mexico favored guerrilla warfare, and the insurgents enjoyed support from many rural communities who provided intelligence, supplies, and recruits.

## The Iturbide Phase and Consummation (1820-1821)

The final phase of the independence war began with political changes in Spain. The Liberal Revolution of 1820 forced King Ferdinand VII to restore the liberal Constitution of 1812, which included provisions that alarmed conservative elements in Mexico. The constitution reduced the privileges of the Catholic Church and the military, threatening the interests of powerful groups that had previously supported Spanish rule.

**Agustín de Iturbide**, a criollo military officer who had fought against the insurgents, recognized that the political situation had changed. In February 1821, he issued the **Plan of Iguala**, which called for Mexican independence under three guarantees: the preservation of the Catholic religion, the equality of all inhabitants, and union between Europeans and Americans.

Iturbide's plan attracted broad support because it promised independence without social revolution. Conservative criollos, who had opposed earlier independence movements, now saw liberation as the best way to preserve their privileges. Iturbide negotiated an alliance with Vicente Guerrero, uniting former enemies under the banner of the **Army of the Three Guarantees**.

The Spanish colonial government, weakened by years of warfare and lacking support from Spain, could not resist this broad coalition. On August 24, 1821, Iturbide and the Spanish viceroy Juan O'Donojú signed the **Treaty of Córdoba**, which recognized Mexican independence. On September 27, 1821, the Army of the Three Guarantees entered Mexico City, marking the formal end of Spanish colonial rule.

## Consequences and Legacy

The Mexican War of Independence created the largest Spanish-speaking nation in the Americas and established Mexico as a major power in the Western Hemisphere. The new nation initially encompassed territory from California to Central America, making it one of the world's largest countries by area.

However, independence did not resolve the social and economic problems that had contributed to the revolution. The war had devastated Mexico's economy, destroyed much of its infrastructure, and left the country deeply divided along regional, ethnic, and class lines. The promise of equality for all citizens remained largely unfulfilled, as indigenous peoples and the poor continued to face discrimination and poverty.

The independence struggle established important precedents for Mexican political culture, including the tradition of popular uprising against illegitimate authority and the role of the military in politics. The war's heroes, particularly Hidalgo and Morelos, became central figures in Mexican national mythology and symbols of resistance against oppression.

The success of Mexican independence inspired other Latin American independence movements and contributed to the collapse of the Spanish Empire in the Americas. It also influenced the development of Mexican national identity, which combined indigenous, Spanish, and mestizo elements into a unique cultural synthesis.
