I found this very short video about the Ghana Empire which I am sharing below. This is just to wet your appetite. There are quite a few really good documentaries out there on the Ghana Empire. Two of them stand out to me, Lost Kingdoms of Africa, Episode 4: Western Africa by Gus Casely-Hayford, and The History of Africa, Episode 10: Desert Empires by Zeinab Badawi based on UNESCO‘s General History of Africa, which I cited earlier.
