ku klux

 The name adopted in the southern part of the United States by a secret political organization, active for several years after the close of the Civil War, and having for its aim the repression of the political power of the freed negroes; -- called also Kuklux Klan and the Klan. It exerienced a revival in the 1920's, in the north as well as the south, and persists as a weak organization into the 1990's. Its goals were primarily anti-negro and anti-Catholic, and its tactics included terrorist attacks on negroes for the purpose of intimidation with the goal of continuing segregation. The signature activity of the Klan was the burning of a cross, either at rallies of Klansmen, or on the property of African-Americans which they hoped to intimidate.  [1913 Webster]
