The contemporary situation in the United States with respect to Mexican migrants has reached a level of intensity that harkens back to the mass expulsions of the 1930s and the 1950s, when millions were forcefully removed south across the border. Recent deportation raids have targeted food processing plants and other large businesses hiring migrant workers from Mexico and Central America. By portraying the current raids as something new, the U.S. media decontexualizes them and strips them of historical memory. In fact, the current raids can be reconstructed and historicized to the moment when Euro-American settlers first encountered Mexicans in the early 1800s. Evidence taken primarily from Mexican archives reveals that expulsions first occurred in the mid-1830s and continued throughout the nineteenth century, especially in areas where local populations were demographically overwhelmed. This period has traditionally been overlooked by U.S., Chicana/o, and Mexican historiographers alike. The contemporary expulsions serve to discourage the contribution of migrants and separate individuals from their families, and they ultimately contradict the time-honored idea that the United States is a "nation of immigrants."
