Did the Mexican Americans residents of these territories become U.S citizenswere they treated as the equals of Anglo citizens?

Mexican American residents of territories acquired by the U.S. after the Mexican-American War were granted U.S. citizenship in 1848, following the Treaty of Guadalupe Hidalgo. However, despite their citizenship, they often faced systemic discrimination and were not treated as equals to Anglo citizens. Many experienced social, economic, and political marginalization, which hindered their full integration into American society. Consequently, the promise of equality remained largely unfulfilled for many Mexican Americans in these territories.
