Where is that Confederate Battle Flag? All I see is the Stars & Stripes.
""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... It was organized at Pulaski, Tenn., in May, 1866...dressed in flowing white sheets, their faces covered with white masks, and with skulls at their saddle horns, posed as spirits of the Confederate dead returned from the battlefields. Although the Klan was often able to achieve its aims by terror alone, whippings and lynchings were also used, not only against blacks but also against the so-called carpetbaggers and scalawags...A general organization of the local Klans was effected in Apr., 1867, at Nashville, Tenn. Gen. N. B. Forrest, the famous Confederate cavalry leader, was made Grand Wizard of the Empire and was assisted by ten Genii. Each state constituted a Realm under a Grand Dragon with eight Hydras as a staff; several counties formed a Dominion controlled by a Grand Titan and six Furies; a county was a Province ruled by a Grand Giant and four Night Hawks; the local Den was governed by a Grand Cyclops with two Night Hawks as aides. The individual members were called Ghouls...The Klan was particularly effective in systematically keeping black men away from the polls, so that the ex-Confederates gained political control in many states."

That answer your question about the Klan's confederate "hertiage"? I don't see any union vets from the war between the states showing up at their grand opening.
