The Ku Klux Klan was formed as a social club by a group of Confederate Army veterans in Pulaski, Tennessee in the winter of 1865-66. The group adopted the name Ku Klux Klan from the Greek word "kyklos," meaning circle, and the English word clan. In the summer of 1867, the Klan became the "Invisible Empire of the South" at a convention in Nashville, Tennessee attended by delegates from former Confederate states. The group was presided over General Nathan Bedford Forrest, who is believed to have been the first Grand Wizard -- the title for the head of the organization.
