Mande-influenced caste systems, and elements thereof, sometimes spread, due to Mande influences, to non-Mande-speaking groups (in and near regions where Mande cultures settled) and were adopted by certain non-Mande peoples of Senegal, parts of Burkina Faso, northern Ghana, and elsewhere the Western Sudan and Western Sahel regions of West Africa. Among the non-Mande Wolof people, craft and bardic castes were collectively termed "nyeno".
