On Thanksgiving night in 1915, fifty years after the close of the Civil War, Simmons and fifteen other men clambered up the granite monolith of Stone Mountain in Georgia. They built an altar on which they laid a Bible, an American flag, and a sword. The men set fire to a cross and shouted to the heavens an oath of allegiance to the Invisible Empire of a new age. The Ku Klux Klan had risen, Simmons proclaimed, “awakened from a slumber of a half a century.”
