The recent release of a landmark report on the history of lynching in the United States is a welcome contribution to the struggle over American collective memory. One dimension of mob violence that is often overlooked, however, is that lynchers targeted many other racial and ethnic minorities in the United States, including Native Americans, Italians, Chinese and, especially, Mexicans. Americans are largely unaware that Mexicans were frequently the targets of lynch mobs, from the mid-19th century until well into the 20th century, second only to African-Americans in the scale and scope of the crimes. From 1848 to 1928, mobs murdered thousands of Mexicans. These lynchings occurred not only in the southwestern states of Arizona, California, New Mexico and Texas, but also in states far from the border, like Nebraska and Wyoming. Some of these cases did appear in press accounts, when reporters depicted them as violent public spectacles, as they did with many lynchings of African-Americans in the South. The story of mob violence against Mexicans in the Southwest compels us to rethink the history of lynching. Southern blacks were the group most often targeted, but comparing the histories of the South and the West strengthens our understanding of mob violence in both.
