Explanation: The Ghana Empire, properly known as Wagadou (as Ghana was the title of its ruler), was a West African empire located in the area occupied by present-day southeastern Mauritania and western Mali.

It also helped that Ghana had many trade routes that were well protected by its large military force as this encouraged other merchants to come to Ghana for trade.
