As with other terrorist and extremist organizations, religion forms the basis of the Ku Klux Klan's dogmatic philosophy, providing justification for its beliefs and actions. The Klan represents a link to America's cultural past. While America has undergone tremendous social change, the secretive order has, since the end of the Civil War, kept alive the antiquated values—predicated on racism and religion—of white supremacism. Covering nearly a century of Klan ideology, this book examines the group's religious rhetoric in its literature and songs, from its heyday during the 1920s to 2014.
