"Spirits and Slaves in Central Sudan" is a historical ethnography that explores the complex relationship between zar, a form of spirit possession, and the life stories of former slaves in central Sudan. The book examines how the experiences of slavery have shaped cultural practices and social structures in this region over the centuries. Through the analysis of zar, it becomes clear that despite differing social and cultural contexts, traditions and belief systems continue to be influenced by the experiences of slavery. The author, Susan M. Kenyon, provides deep insight into the cultural dynamics and historical development of these practices, making the book a valuable resource for students and researchers in the fields of history and ethnology.
