Cortez set the basis for social, economic, ethnic, religious, political changes in what is now Mexico, which was of great benefit for the Spanish, but devastating to the local populations.
Explanation:
Hernan Cortez was a Spanish conquistador. He was sent in what is now Mexico in order to gain territory for the Spanish crown, and get as much wealth as possible. In order to do so, Cortez was merciless, and that had devastating effects on the locals.
The Spanish conquistadors massacred the local populations. They destroyed their culture, their cities, and gave their best to assimilate them. On top of that, the diseases that spread out from the Spanish killed off much of the local populations.
Cortez, and the other conquistadors, took every piece of gold and silver they were able to get their hands on, robbing the region. For the Spanish that was of great benefit though, as they became very wealthy and powerful.

- Aztecs
- Zapotecs
- Toltecs
- Maya
- Tlaxcala
- Mixtec
