In the 12th Century, Oxford was a primitive village stuck in the Medieval Dark Ages. Meanwhile Africa had powerful Kingdoms like the Mali Empire. The Universities of Timbuktu and Sankore were thriving centers of scholarship and research. Scholars came all the way from Greece and Macedonia to study there.
In those days, the most primitive people were Northern Europeans like the Germanic, Celtic , Anglo-Saxon and Frankish tribes (i.e. Franks, Vandals, Visigoths, Barbarians, etc) The Mediterranean tribes like Greeks and Romans colonised and civilised them.
The ancient Romans described the German tribes thus:
"
They are nearer to animals than men. They are by nature unthinking, and their manners are crude. Their bellies protrude, their colour is white and their hair long. In sharpness and delicacy of spirit and in intellectual propensity, they are NIL. Ignorance, lack of reasoning power and boorishness is common among them"
African people were in Europe in the Middle Ages in high ranking positions. They were called Moors. The most advanced part of Europe was Spain which was ruled by the Moors for 700 years.
