The Ku Klux Klan (KKK), or just the Klan is the name of three distinct movements in the United States. They first played a violent role against African Americans in the South during the Reconstruction Era of the 1860s. The second was a very large controversial nationwide organization in the 1920s. The current manifestation consists of numerous small unconnected groups that use the KKK name. They have all emphasized secrecy and distinctive costumes, and all have called for purification of American society, and all are considered right-wing.
