Book excerpt: The Ku Klux Klan, the Aryan Nations, and many ultra-right-wing racist "religious" organizations adhere to a doctrine called Christian Identity. Christian Identity is not a denomination, but a loosely organized movement embracing a range of beliefs. Its foundation is the theory that Anglo-Saxons (and Aryans, in most cases) are the true descendants of the Lost Tribes of Israel, and are the chosen people of God. Christian Identity is a bloodline religion: a belief system irrevocably tied to race. As such it lends itself to the violence, racism, and anti-Semitism of its more militant practitioners, and its growth and links to domestic terrorism warrant a better understanding of the movement. This survey of the Christian Identity Movement traces its development and beliefs, from its origins to its modern manifestations. It examines the doctrines and visions of the future of Identity communities and organizations in America. The initial chapter explores British Israelism, forerunner of most bloodline Identity groups; the oral traditions behind the movement are reviewed in the second. The third chapter outlines the American Israel, Israel Identity and bloodline Identity movements, including major figures and groups. The following chapters provide an introduction to Christian Identity itself, its general religious tenets, and post-Creation beliefs upon which much of the theory is based. Subsequent chapters describe militant bloodline and Identity groups, and individual militant Identity leaders. The final chapter explores the "Third American Revolution" predicted by these groups, a forthcoming war based on race and religion.
