Ritual and Religion among the Kapsiki/Higi of North Cameroon and Northeastern Nigeria

Walter E. A. van Beek draws on over four decades of extensive fieldwork to offer an in-depth study of the religion of the Kapsiki/Higi, who live in the Mandara Mountains on the border between North Cameroon and Northeast Nigeria. Concentrating on ritual as the core of traditional religion, van Beek shows how Kapsiki/Higi practices have endured through the long and turbulent history of the region.
