Unlike other ethnic minorities in the United States, American Indians are defined not solely by self-designation but by federal, state, and tribal laws. Blood quantum�originating from archaic notions of biological race and still codified in contemporary policy�remains one of the most important factors in determining tribal citizenship, access to services, and community recognition. This concept, however, is not without debate and contestation. This symposium features Native scholars who approach this important and complex topic from various perspectives. Sociologists Eva Marie Garroutte (Boston College) and C. Matthew Snipp (Stanford) join historian Malinda Lowery (UNC Chapel Hill) and anthropologist Kimberly TallBear (UC Berkeley) in a discussion moderated by museum historian Gabrielle Tayac. Presented on September 16, 2011.
