Timbuktu: The Jewish-African Kingdom of Ghana

wrong , Eastern roman empire , Kiev, Novgorod Republic were way more advanced

 

Cordova had between 500.000 to one million inhabitants in X century when Kiev was....a little village?

 

Not even, mate. Sorry. They may have been the more advanced versions of themselves, but almost any southern civilization around the Mid-East and Meditterranean was more advanced. One could argue that the more ancient civilizations of these regions were more advanced or on par with Northern European and East Europe at the time.

Not that this really should be taken ill by those peoples. All things said and done, whatever the past was, Europeans unquestionably dominate the present so the gradient of improvement is remarkable especially because they were so late in appearing on the map of what we've come to consider "civilized societies". That's my view of it anyway. You can't look at these things and believe one person was superior over the other rather than believing that each civilization comes to power through a combination of circumstance and struggle.

 

Zuwa Alyaman was a member of one of the Jewish communities transported from Yemen by the Abbysinians in the 6th century C.E. after the defeat of Dhu Nuwas. You remember the burning of the Christians of Najran by the Jewish king of Yemen.. He too was a convert.
