Answer:
Mexico gained its independence from Spain in 1821 after a long and bloody struggle.
Step-by-step explanation:
Here is a simple explanation of how it happened:
In 1810, a priest named Miguel Hidalgo y Costilla launched a rebellion against the Spanish colonial government in Mexico. Hidalgo's army was made up of poor farmers, miners, and indigenous people who were tired of being exploited by the wealthy Spanish landowners.
Although Hidalgo's army won some early victories, they were ultimately defeated by the better-trained and better-equipped Spanish forces. Hidalgo himself was captured and executed in 1811.
However, the movement for independence did not die with Hidalgo. Other leaders, such as Jose Maria Morelos and Vicente Guerrero, continued the struggle for independence. In 1820, a group of Spanish liberal officers overthrew the conservative government in Spain and proclaimed a new constitution that gave more rights to the colonies.
In response, a group of Mexican rebels, led by Agustin de Iturbide, joined forces with the Spanish royalists to fight for independence. Iturbide's army was successful, and he declared Mexico's independence on September 27, 1821.
Thus, Mexico gained its independence through a combination of popular uprisings, guerrilla warfare, and political negotiations.
