Lynching was the occurrence of extrajudicial killings that began in the United States' pre–Civil War South in the 1830s and had mostly ended by time of the civil rights movement in the 1950s and 1960s, although instances occurred as late as 1981. Although the victims of lynchings were members of various ethnicities, after roughly 4 million enslaved African Americans were emancipated, they became the primary victims of lynchings by white Southerners. Lynchings in the U.S. reached their height from the 1890s to the 1920s, and they primarily victimized ethnic minorities. Most of the lynchings occurred in the American South, as the majority of African Americans lived there, but racially motivated lynchings also occurred in the Midwest and the border states of the Southwest, where Mexicans were often the victims of lynchings. In 1891, the largest single mass lynching (11) in American history was perpetrated in New Orleans against Italian immigrants.
Lynchings followed African Americans with the Great Migration (c. 1916–1970) out of the American South, and were often perpetrated to enforce white supremacy and intimidate ethnic minorities along with other acts of racial terrorism. A significant number of lynching victims were accused of murder or attempted murder. Rape, attempted rape, or other forms of sexual assault were the second most common accusation; these accusations were often used as a pretext for lynching African Americans who were accused of violating Jim Crow era etiquette or engaged in economic competition with Whites. One study found that there were "4,467 total victims of lynching from 1883 to 1941. Of these victims, 4,027 were men, 99 were women, and 341 were of unidentified gender (although likely male); 3,265 were Black, 1,082 were white, 71 were Mexican or of Mexican descent, 38 were American Indian, 10 were Chinese, and 1 was Japanese."
