Ku Klux Klan (The Many Nations of North America)

From Alternative History

Considered by many to be the ideological ancestor of the Supremacy League, the organisation heavily harrassed the black population of the C.S.A and influenced its politicans to keep their rights to a minimum. Its political wing was the White Party, a major Confederate Party until it's decline in the 1920s. It's notable for its role in the decline of the Confederacy.
