Hausa language
The influence of the Hausa language on the languages of many non-Hausa Muslim peoples in Africa is readily apparent. Likewise, many Hausa cultural practices, including such overt features as dress and food, are shared by other Muslim communities. Because of the dominant position which the Hausa language and culture have long held, the study of Hausa provides crucial background for other areas such as African history, politics (particularly in Nigeria and Niger), gender studies, commerce, and the arts.
