Who can explain the ghana empire​

The Ghana Empire ( c. 300 until c. 1100), properly known as Wagadou (Ghana being the title of its ruler), was a West African empire located in the area of present-day southeastern Mauritania and western Mali. ... As the empire declined, it finally became a vassal of the rising Mali Empire at some point in the 13th century.

Explanation:

Ancient Ghana ruled from around 300 to 1100 CE. The empire first formed when a number of tribes of the Soninke peoples were united under their first king, Dinga Cisse. The government of the empire was a feudal government with local kings who paid tribute to the high king, but ruled their lands as they saw fit.
