"This book tells the story of how the Ashanti, Tutsi, Igbo, Zulu, Beta Israel, Maasai, and many other African peoples came to think of themselves as descendants of the ancient tribes of Israel. Pursuing medieval and modern European race narratives over a millennium in which not only were Jews cast as black but black Africans were cast as Jews, the author reveals a complex history of the interaction between religious and racial labels and their political uses." -- From publisher description.
