Brief chronology of the fight for Mexican Independence

In these days of national holidays, it is worth reviewing our history books to commemorate how the fight, which we celebrate every September 16, was carried out. If you do not remember the most important moments, here we share a brief summary.

Step by step, we take you from the moment it began, on September 16, 1810, and ended, on September 28, 1821.

Context of New Spain in 1808

First, we must go back to 1808. Although there are still two years to go before the fight that would begin with the Grito de Dolores, we must understand the context.

In that year the North American and French revolutions began to become known.

The idea of ​​liberal states reached the colonies, which implied a rejection of monarchies and the search for sovereignty for the peoples.

The population of New Spain, made up mostly of the indigenous population (60 percent) and castas (22 percent), began to feel discontent towards the crown.

In addition, in May of that year the King of Spain Fernando VII abdicated the crown in favor of Carlos IV, who in turn resigned in favor of Napoleon.

This generated general discontent and a series of uprisings.

There was even a coup attempt by merchants after this announcement. This began to germinate the idea of ​​conspiracies.

In the house of Josefa Ortiz de Domínguez, literary gatherings were held, attended by Miguel Allende and Juan Aldama, as well as some priests such as Miguel Hidalgo y Costilla. There they planned a conspiracy for December, during the San Juan de los Lagos fair.

September 13: Ignacio Garrido denounces the conspiracy plan in Querétaro.

  • September 14: Josefa Ortiz de Domíngues warns that they were discovered.
  • September 15: That night, Ignacio Allende intercepts the arrest warrant and goes to Dolores, where Miguel Hidalgo decides to take up arms.
  • September 16: The priest Miguel Hidalgo calls for a mass in the early morning, given that it was Sunday. Instead of offering Sunday service, he invites people to join the fight against bad government. There the fight for independence began to take shape.

  • September 23: Viceroy Venegas arms an army against Hidalgo’s movement. He calls it the royalist army.
  • October: The insurgent movement had already taken Guanajuato, Aguascalientes, Valladolid and Guadalajara. It looked like they might succeed.

  • October 14: The heads of Hidalgo, Allende and Adama are shown in Guanajuato so that the remaining insurgents would surrender. It didn’t work for them.
    In the absence of a legitimate king, the Spanish Cortes enacted a Constitution establishing a Spanish constitutional monarchy.
    With this it was a matter of maintaining order and helping to carry out a counterrevolution; however, citizens did not get the autonomy they wanted.
    For his part, José María Morelos continues his fight in the south, in which he was doing more or less well.
    The insurgents continued fighting despite having little army and few resources. With the help of Guadalupe Victoria and Vicente Guerrero, they took over Chilpancingo, Tixtla, Chilapa, Taxco, Cuatla, among others.
  • September 14: José María Morelos y Pavón establishes a congress to exercise sovereignty. There he reads “Sentiments to the Nation”, where he declares a free America and is named Servant of the Nation.

  • July 14: Morelos writes to the president of the United States, James Madison, to recognize the independence of New Spain.

    September 23: The royalist forces flee towards Veracruz.
    September 27: Triguarante Army enters Mexico City! Mexican independence is consummated!
