These edited proceedings of a 2013 symposium at Northwestern University are organized around the question of how to theorize the study of Africana religions across wide expanses of time and space. An international body of scholars representing the fields of history, religious studies, anthropology, American studies, sociology, African studies, classics, and African American studies gathered in a two-day event to consider the past, present, and future of their shared commitment to understanding the religions of African and african-descended people. Scholars discuss the challenges of and opportunities for the study of Africana religions from ancient to modern times, across Africa and its diaspora.
