After the Civil War, segregation developed as a method of group control. For both minority groups, segregation existed in [Texas] schools, churches, residential districts, and most public places such as restaurants, theaters, and barber shops. By the latter years of the nineteenth century, institutionalized segregation flourished legally in places with a visible Black population and was extended informally to Tejanos. Most Texas towns and cities had a “Negro quarter” and a “Mexican quarter.”
