Now to Ghana. This medieval kingdom is touched upon in the UCSD series MMW 3, more specifically in the series by Professor Herbst in lecture 15 (May 20th, 2008). Mostly, Africa has been tribal, but a kingdom could come into existence because of trade. Trade became possible as soon as the Arabs and Berbers figured out, how to cross the Sahara with camels. With the camels they brought in salt from the salt pans in the Sahara and traded it, most importantly for gold. Ghana was a kingdom situated roughly where today are Mauretania and Mali. The gold was not from their soil, they got it from peoples further south. With trade, also Islam reached this part of the world. Soon the elite of the Kingdom of Ghana became Muslims.I was wondering whether also in earlier times gold made it from West-Africa to the rest of the world. Maybe through Egypt or Ethiopia. There are so many questions and so few podcasts with answers. Maybe there are very few sources, but I wouldn't be surprised if there was also little research. Africa still lies largely undiscovered.
