What were 2 changes Mexico made when it took control of the southwest?

* The Spanish language became the official language. This had a profound impact on the region, as it meant that many Native American languages were no longer spoken or understood. It also made it more difficult for Native Americans to participate in civic life, as they were often not fluent in Spanish.

* The Catholic Church became the official religion. This also had a major impact on the region, as it meant that many Native American religious practices were suppressed or outlawed. It also led to the destruction of many Native American religious sites.
