Book excerpt: In some places during Reconstruction, the Ku Klux Klan (KKK) was a social fraternity whose members enjoyed sophomoric high jinks and homemade liquor. In other areas, the KKK was a paramilitary group intent on keeping former slaves away from white women and Republicans away from ballot boxes. South Carolina saw the worst Klan violence and, in 1871, President Grant sent federal troops under the command of Major Lewis Merrill to restore law and order. Merrill did not eradicate the Klan, but he arguably did more than any other person or entity to expose the identity of the Invisible Empire as a group of hooded, brutish, homegrown terrorists. In compiling evidence to prosecute the leading Klansmen and restoring at least a semblance of order to South Carolina, Merrill and his men demonstrated that the portrayal of the KKK as a chivalric organization was at best a myth and at worst a lie.
