Mexico was the most important colony of Spain, it was called the "Virreinato de la Nueva España", which is English for "Viceroyalty of New Spain". It was mostly populated by Native American slaves, some Criollos (sons of Spaniards born in Mexico) and the Peninsulares elitees (Spaniards born in Spain). For three hundred years Peninsulares always ruled above Criollos. This, along with the Bourbonic reforms which pretended to diminish the privileges and the power of the most conservative elitees (mainly the church) eventually led to what would be known as the War of Mexican Independence, orchestrated by the Criollos and Peninsulares which pretended to achieve independence so they could keep their privileges.
