This is all I can give you right now but someone else can do better than me:
The Spanish conquest of the Aztec Empire, also known as the Conquest of Mexico or the Spanish-Aztec War (1519–21),[7] was one of the primary events in the Spanish colonization of the Americas. There are multiple 16th-century narratives of the events by Spanish conquistadors, their indigenous allies, and the defeated Aztecs. It was not solely a contest between a small contingent of Spaniards defeating the Aztec Empire but rather the creation of a coalition of Spanish invaders with tributaries to the Aztecs, and most especially the Aztecs' indigenous enemies and rivals. They combined forces to defeat the Mexica of Tenochtitlan over a two-year period. For the Spanish, the expedition to Mexico was part of a project of Spanish colonization of the New World after twenty-five years of permanent Spanish settlement and further exploration in the Caribbean.
Both the Aztec and the Inca empires were conquered by Spanish conquistadors, while the Aztec Empire was conquered by Cortés, the Inca Empire was defeated by Pizarro. The Spanish consolidated control of what became the colony of New Spain. The spaniards virtually enslaved the native people and resulted in widespread death and depopulation for the native people since the conquistadors killed many Native Americans in raids and wars, and they brought deadly epidemic diseases.
