The Mali Empire (c. 1235–1600s), once West Africa's wealthiest power, unraveled through a cascade of internal and external pressures in the 15th–16th centuries:
Songhai, centered on Gao, broke away under Sunni Ali (1464–1492) and Askia Muhammad (1493–1528). They conquered Timbuktu (1468) and Jenne, seizing Mali's intellectual and commercial heart. Mali lost control of the Niger bend trade.
Post-Mansa Musa (d. 1337), succession disputes became chronic. Rival claimants, court factions, and provincial governors (farbas) acting independently eroded central authority. The Mansa became a figurehead.
Recurrent droughts (linked to global Little Ice Age shifts) devastated agriculture in the Sahel. Famine depopulated cities, reduced tax revenue, and triggered migrations that destabilized peripheries.
Portuguese caravels (1440s+) established coastal trade (gold, ivory, slaves) bypassing trans-Saharan caravans. Mali's gold monopoly evaporated; revenue collapsed. North African demand shifted to Atlantic ports.
Sultan Ahmad al-Mansur of Morocco invaded Songhai (not Mali directly) with arquebusiers at Battle of Tondibi. Songhai shattered. The resulting chaos, Tuareg raids, and fragmentation of the western Sudan ended any residual Mali authority. Remnants lingered in Kaarta/Kangaba but as minor chiefdoms.
Mali's reliance on gold tax, lack of economic diversification, and failure to integrate firearms or naval power left it obsolete.
The empire didn't fall in a day—it dissolved over 150 years, a victim of success (gold), geography, climate, and the tides of global trade.
