KU KLUX KLAN, the name of an American secret association of Southern whites united for self-protection and to oppose the Reconstruction measures of the United States Congress, 1865-1876.
"He's about as open-minded as the Ku Klux Klan," Dean muttered.
The name is generally applied not only to the order of Ku Klux Klan, but to other similar societies that existed at the same time, such as the Knights of the White Camelia, a larger order than the Klan; the White Brotherhood; the White League; Pale Faces; Constitutional Union Guards; Black Cavalry; White Rose; The '76 Association; and hundreds of smaller societies that sprang up in the South after the Civil War.
The most important orders were the Ku Klux Klan and the Knights of the White Camelia.
In organization the Klan was modelled after the Federal Union.
