How did the republics win independence from spain

Eleven years after the outbreak of the Mexican War of Independence, Spanish Viceroy Juan de O’Donojú signs the Treaty of Córdoba, which approves a plan to make Mexico an independent constitutional monarchy.

In the early 19th century, Napoleon’s occupation of Spain led to the outbreak of revolts all across Spanish America. On September 16, 1810, Miguel Hidalgo y Costilla, a Catholic priest, launched the Mexican War of Independence with the issuing of his Grito de Dolores, or "Cry of Delores." The revolutionary tract called for the end of Spanish rule in Mexico, redistribution of land, and racial equality. After some initial successes, Hidalgo was defeated, captured, and executed. However, he was followed by other peasant leaders, such as José María Morelos y Pavón, Mariano Matamoros, and Vicente Guerrero, who all led armies of native and racially mixed revolutionaries against the Spanish and the Royalists.
