The Ku Klux Klan originated in Pulaski, Tennessee in 1866 and was founded by former Confederate soldiers. It quickly evolved from a social club into a violent secret terrorist organization that used intimidation and violence against Republicans, both black and white, in an effort to overthrow Republican state governments in the South during Reconstruction. The Klan spread throughout the South in the late 1860s, conducting night rides to attack and intimidate blacks, Republicans, and their allies. Their goal was to reverse the political gains of blacks and restore white supremacy across the South through violence and terror.
