Abstract

After the U.S. annexed much of Mexico following the Mexican-American War, Mexicans in the incorporated regions began to think of themselves as a racial group within the U.S. rather than a distinctive nationality. The 1848 Treaty of Guadalupe Hidalgo promised citizenship rights to all Mexicans in the area. The Treaty promises rarely were put into practice, as they were left up to the enforcement of territories and states. Even where enforced, the rights of citizenship were restricted and defined on the basis of race. Local laws excluded Afro-Mexicans and Mexican Natives from exercising the rights promised by the Treaty. This restriction served to transform what was once a multiracial Mexican nationality into one distinctive race among many in the U.S. As the Mexican American landed elites of the antebellum period began to lose their land and status in the face of challenges from the new migrants, a new Mexican American elite of educated professionals involved in political organizations began to emerge. In Texas, New Mexico, and California, these elite Mexicans began to use variations of the phrase “la raza,” the race, to refer to themselves. The influx of North American migrants, the commercial boom after the Civil War, the rise of the press, and the emergence of labor organizations helped to develop this identity into part of the language of social movements. Long before the rise of the Chicano Movement in the twentieth century, Mexican Americans came to see themselves as a people with a shared political identity.
