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

After the U.S. annexation of territories like Texas and California, many Mexican American residents were granted U.S. citizenship under the Treaty of Guadalupe Hidalgo in 1848. However, despite their legal status, they often faced discrimination and were not treated as equals to Anglo citizens, experiencing social, economic, and political marginalization. This inequality persisted for decades, contributing to systemic racism and segregation against Mexican Americans.
