Some of the kingdoms in West Africa claim they came from the middle east originally. Has nothing to do with hamatic hypothesis. This is what the people themselves have been saying since day 1. Yoruba and Hausa specifically have a story of coming from the middle east. But so what? We know Africans left the continent LONG ago and founded city states in mesopotamia and elsewhere. If you go to Iran today, about 50% of that country is still black as they were the day they got there. So it isn't far fetched to think, as northern invaders came and ruling families couldn't hold on, they left with some citizens in tow to found other areas. That isn't a far fetched idea. Though not the same distance, we see the same thing happen in Sierra Leone, Liberia and Ivory Cost. When Songhai was destroyed royal families and citizens left and settled in Liberia and from there expanded into other areas.
There is a African American professor named Michael Gomez from NYU who says he is starting to give more credence to the claims of Africans in certain kingdoms claiming they came from the middle east. Again doesn't mean there were hemites. The world is very old, and populations are not static. Entire populations can be replaced or wiped out in less than 100 yrs. Just look at the United States. If we go back 800 yrs ago, that country looked like a totally different place demographically than it does now. I am not saying its true, but I would think the people/kingdoms would know their history better than we, reading second hand books would.
I hope you get what I am saying. I am not saying i believe in hametic non sense. I am saying, I believe originally a lot of the old kingdoms in the middle east were black people. For instance we know the greeks described the phoencians as "Ethiops". Was it the Sumerians or Akkadians who called themselves the "black heads"? I figure the kingdom of Kush probably expanded to those areas looong ago in their sons stayed there and eventually built up these kingdoms. Then fell back to Africa when they couldn't hold off invaders. But this doesn't detract from Africa! I mean the iron age for the world was 1500 b.c. however for Africans the iron age was around 2500 b.c. or older. We have the oldest kingdom on the planet that I know of, in the form of Kush which was MUCH older than Kemet. So we Africans can not be diminished, but we shouldn't diminish what our brothers did in other areas too. You also know Africans had great kingdoms in India too? I think they were Aksumite.
It is actually quite common for Islamized groups to claim forgein descent, even some Arab tribes claim descent from the Prophet Muhammad despite having no actual ties or relations with such people it's even a common practice in North Africa in places such as Morocco and some of it's former existing dynasties also having made similar claims. So it's nothing new.
