The three major West African kingdoms of Ghana, Mali, and Songhay prospered from trade. Ghana lasted from 750-1075 AD as a prominent trading hub of gold. Mali then rose to power from 1200-1500 AD under Mansa Musa, becoming the second largest empire after Mongolia. Songhay broke away from Mali in 1350 and expanded along the Niger River until internal revolts caused its fall in 1600. These kingdoms grew powerful through their strategic positions facilitating trade between Africa, Europe, and Asia.
