What happened to the Mexicans of the Texas annexation?

After the annexation of Texas in 1845, many Mexicans living in the region faced significant challenges. Following the Texas Revolution, which had led to independence from Mexico in 1836, the new Texan government implemented policies that marginalized the Mexican population, including land dispossession and legal discrimination. The annexation intensified tensions between the U.S. and Mexico, ultimately leading to the Mexican-American War (1846-1848), which further complicated the status and rights of Mexicans in Texas. Over time, many Mexicans became U.S. citizens, but issues of inequality and social discrimination persisted.
