Answer: Colonial currents, trade and, missionary work.
Explanation:
Africa has long been an area of interest for European powers. Colonization reached its peak in that part of the world. In such conditions, there was cultural assimilation of certain indigenous communities in Africa. Even before colonization itself, Catholic missionaries spread Catholicism throughout the continent. Many have accepted Catholicism and thus cultural patterns imposed from Europe. And Islamic traders also spread Islam in that part of the world. A conglomeration of different cultural and religious patterns brought from other parts of the world has emerged on the African continent.
