How did the government take over new Spain?

The government took over New Spain through a combination of military conquest and colonial administration. Following the Spanish conquest of the Aztec Empire in the early 16th century, Spain established a viceroyalty to govern the territory, which was formalized in 1535 with the appointment of a viceroy. This centralized authority allowed Spain to implement its laws, extract resources, and convert Indigenous populations to Christianity. Over time, the governance evolved into a complex bureaucracy that aimed to maintain Spanish control over the region.
