The legacy of slavery and racism did not end after the Civil War. In fact it can be argued that extreme violence against people of color became even worse with the rise of vigilante groups who resisted Reconstruction. Because vigilantes, by definition, have no external restraints, lynch mobs had a justified reputation for hanging minorities first and asking questions later. Because of its tradition of slavery, which rested on the racist rationalization that Blacks were sub-human, America had a long and shameful history of mistreating people of color, long after the end of the Civil War. Perhaps the most infamous American vigilante group, the Ku Klux Klan started in the 1860s, was notorious for assaulting and lynching Black men for transgressions that would not be considered crimes at all, had a White man committed them. Lynching occurred across the entire county not just in the South. Finally, in 1871 Congress passed the Ku Klux Klan Act, which prohibited state actors from violating the Civil Rights of all citizens in part because of law enforcements’ involvement with the infamous group. This legislation, however, did not stem the tide of racial or ethnic abuse that persisted well into the 1960s.
