How did the treaty ending the Mexican war effect Mexican Americans living in the Mexican cession?

The Treaty of Guadalupe Hidalgo, which ended the Mexican-American War in 1848, had significant implications for Mexican Americans living in the Mexican Cession. It granted them U.S. citizenship and the rights that came with it, but many faced discrimination, land dispossession, and cultural marginalization as a result of the transition. While some retained their land, others lost it due to legal loopholes and aggressive land claims by Anglo settlers. Overall, the treaty marked a complex shift in their social, political, and economic status within the newly formed American territories.
