The Mexican Independence movement (1810–1821) was a long and complex process that marked the end of the Viceroyalty of New Spain and the birth of a sovereign nation. It was not a single uprising but a series of stages that combined popular revolts, military struggles, political tensions, and Enlightenment ideals that sought to transform the established order.
The movement for independence was fueled by both internal and external factors:
Social inequality among peninsulares, criollos, mestizos, Indigenous peoples, and Afro-descendants.
Economic crisis in the viceroyalty and discontent over heavy taxation.
Influence of Enlightenment ideas and events such as the French Revolution and U.S. independence.
Instability of the Spanish monarchy, following Napoleon’s invasion and the abdication of Ferdinand VII.
On September 16, 1810, Miguel Hidalgo y Costilla issued the Grito de Dolores, calling on the population to rise against viceregal rule. He was joined by Ignacio Allende, Juan Aldama, and other leaders who mobilized thousands of peasants, Indigenous people, and mestizos in the first insurgent phase.
First stage (1810–1811): Led by Hidalgo, ending with his defeat at the Battle of Puente de Calderón.
Second stage (1811–1815): José María Morelos reorganized the movement, convened the Congress of Chilpancingo, and presented the Sentiments of the Nation.
Third stage (1815–1820): Guerrilla warfare led by Vicente Guerrero, Guadalupe Victoria, and others kept resistance alive.
Consummation (1821): The alliance between Guerrero and Agustín de Iturbide resulted in the Plan of Iguala, which proclaimed independence under the Three Guarantees: religion, independence, and unity.
Mexican independence brought profound changes:
The end of the Viceroyalty of New Spain.
The beginning of the First Mexican Empire under Agustín de Iturbide.
A politically divided country, torn between liberals and conservatives.
The emergence of a new national identity rooted in cultural and social diversity.
The Mexican Independence movement was more than a war; it was a social, political, and cultural process that profoundly reshaped the country’s history. Its legacy lives on in the collective memory and in the annual September 16th celebrations, commemorating the beginning of Mexico’s path to freedom.
