Source: Ethnogenesis From Within The Chadic State Some Thoughts on the History of Kanem-Borno (Paideuma) 1993 A.D.
This source confirms yet again the ancient near east (ANE) of ancient Chadic peoples. This source along with other works from Dr. Dierk Lange confirms that numerous peoples from ancient Assyria were a part of the ancient establishment of sub-Saharan African state building. This source (along with Dr. Lange’s later works) highlights how the ethnic groups we recognize now are the direct, ethnic offshoots and derivations from the original founding ethnic groups from the ANE. The original founding ethnic groups developed into many ethnic offshoots and assimilation (combined with internal conflict, dynastic changes, and the rise of Islam) assisted in the lost of certain near east aspects such as language but fundamentals such as customs and state complexity remained. In conclusion, the original Assyrian deportees divided into new ethnic stratums which are the ethnic groups we have today and Islam assisted in forming some new cultural aspects.
In my opinion, I believe all parts of the Kanuri people’s origins are correct which includes the Yemenite origin. Whenever two or more origins of a people are proposed, I believe it is wise to consider a combination of all three to be correct.
