Between 700 and 1600 there were three great empires in the centre of West Africa: Ancient Ghana, Mali and Songhai. They all grew immensely rich by trading in gold.
Ghana dominated the region between about 750 and 1078. Smaller states in the region at this time included Takrur to the west, the Malinke kingdom of Mali to the south, and the Songhai Empire centred on Gao to the east.
