Professor Donald L. Wiedner published this book in 1964, shortly after the vast majority of countries in Africa achieved independence from colonial rule. The Sahara desert has effectively created two Africas, the one in the north, along the Mediterranean coast, that is primarily Arab and Islamic. The desert itself, and south of it are primarily Black Africa, with mixed religious influences, and that is Wiedner's focus, as indicated by the title.
