Ancient Ghana was the first known great kingdom in West Africa (not to be confused with modern Ghana). The kings of Ancient Ghana ruled from 300 AD and its capital was Kumbi-Saleh.

Ancient Ghana was rich in Gold and it is said that the King of Ancient Ghana was the richest king on the face of the earth.
