After the Civil War, on December 24, 1865, six Confederate veterans founded the Ku Klux Klan (KKK).Horn, 1939, p. 9. The KKK used violence, lynching, murder and acts of intimidation to oppress African Americans in particular, and it created a sensation with its masked forays' dramatic nature. Under President Ulysses Grant the federal government suppressed the Klan in the early 1870s, and it disappeared by the mid-1870s.H.W.
