African belief systems; social organizations; religious rituals; rules of leadership recruitment; the enthronement and dethronement of royalties; the limits of authority and community power, all reveal linear similarities at their most formative levels. In other words, those organizational means and rituals of leadership and worship that seem to have governed Nubian communities radiated to the northern, southern, eastern, and western part of their neighbors. The Red Sea hills, the Abyssinian plateau from where the waters of the Blue Nile originate, created the formative elements of Nubian and Egyptian civilizations. These transformations have, over the centuries, become part of the African mode of thinking and living.
