Within the past thirty years, the narrative established by sympathetic colonial administrators, pioneer African American scholars, nationalist African historians, and the standard explanations of state formation here and elsewhere have been challenged. Recent archaeological research, com-bined with that of historians, art historians, and anthropologists, necessi-tates the rethinking of these established narratives. Excavations in Jenne-Jeno (old Jenne in the modern nation of Mali) have opened an entirely new paradigm of the origins of complex urban-centered societies in Africa (and by extension elsewhere in the world). The emergence of towns in the west-ern and probably central Sudan occurred far earlier than indicated by Arab chronicles and oral traditions.
I find interesting that even though Africa had such advanced urban societies, many historian still have a poor understanding of this.
