There is no worthwhile  contribution of African Civilizations to humanity  that merits research.

A singular historical perspective representing singular African Civilization  has not been institutionalized.

Slavery and colonialism hindered the sober analysis  and articulation of the value of African Civilization.

African civilization is analysed by scholars from the point of view of material and structural perspectives.
