What led to the downfall of the Ghana, Mali?

The fall of Ghana, Mali was due to numerous internal political disputes which brought disruption in trade and ultimately ended its reign through civil war.

Mansa Musa, emperor of Mali, was a great leader. Under his rule, Mali flourished economically and territorially.
