How did the Ku Klux Klan get their name and what exactly did/do their members believe?

The original Ku Klux Klan was organized by ex-Confederate elements to oppose the Reconstruction policies of the radical Republican Congress and to maintain �white supremacy.� After the Civil War, when local government in the South was weak or nonexistent and there were fears of black outrages and even of an insurrection, informal vigilante organizations or armed patrols were formed in almost all communities. These were linked together in societies, such as the Men of Justice, the Pale Faces, the Constitutional Union Guards, the White Brotherhood, and the Order of the White Rose. The Ku Klux Klan was the best known of these, and in time it absorbed many of the smaller organizations.

The second Ku Klux Klan was founded in 1915 by William J. Simmons, an ex-minister and promoter of fraternal orders; its first meeting was held on Stone Mt., Ga. The new Klan had a wider program than its forerunner, for it added to �white supremacy� an intense nativism and anti-Catholicism (it was also anti-Semitic) closely related to that of the Know-Nothing movement of the middle 19th cent. Consequently its appeal was not sectional, and, aided after 1920 by the activities of professional promoters Elizabeth Tyler and Edward Y. Clarke, it spread rapidly throughout the North as well as the South. It furnished an outlet for the militant patriotism aroused by World War I, and it stressed fundamentalism in religion.

After World War II, Dr. Samuel Green of Georgia led a concerted attempt to revive the Klan, but it failed dismally as the organization splintered and as state after state specifically barred the order. Southern civil-rights activities during the 1960s gave the Klan a new impetus and led to revivals of scattered Klan organizations. The most notable of these were Mississippi's White Knights of the Ku Klux Klan, led by Robert Shelton. The newly revived Klan groups were responsible for violent attacks against blacks and civil-rights workers in cities throughout the South, including Jacksonville and St. Augustine, Fla., Birmingham and Montgomery, Ala., and Meridian, Miss. In spite of its efforts, the new Klan was not strong, and by the end of the decade its power and membership had declined to practically nothing. Although a resurgence of support for the Klan was manifest in the surprising popularity in the early 1990s of David Duke of Louisiana, actual membership in Klan organizations is estimated to be in the low thousands.
