- Marking boundaries and identities: the precolonial expansion of segmentary societies in Southwestern Burkina Faso (2000)
- Over approximately the last 200 years, north-west Ghana and large areas of neighbouring southern Burkina Faso were the stage for a highly successful expansion of Dagara-speaking peoples. Probably setting out from an area around Wa, small groups of Dagara migrated towards the north, some of them taking a westward route, crossing the Black Volta river into today’s Burkina Faso. They rarely advanced into nomansland but rather displaced peoples such as Sisala-, Dyan-, Phuie- and Bwamu-speaking groups, who then moved further west and north. Today, the Dagara occupy about 3500 km2 in southern Burkina Faso, where they represent the sixth largest language group. In this paper I wish to explore the history of the north-west frontier of Dagara expansion and the interaction between the “land-owning” Phuo and the incoming Dagara.
