This article, focusing on the operation and abolition of human sacrifice in eastern Yorubaland, examines a key aspect of the dialogue and conflict between Yoruba chiefs and their opponents – slaves, Christians and British colonialists – during the late nineteenth century. The exchange reflected the position of human sacrifice in the consolidation of economic inequalities and socio-cultural privileges. The article examines this controversy in the context of the broader changes of the era, including the ending of the Yoruba wars and the approach of colonial rule. It analyses the interaction of external and internal forces that produced the eventual demise of human sacrifice.
