Lesson Content/Board Summary

Factors That Led To The Fall Of Mali Empire

Internal Factors

The decline of the Mali Empire was significantly influenced by internal weaknesses after Mansa Musa’s reign. These included poor leadership, civil disputes, and military decline.

The following are the internal factors:

Mali’s emperors became incompetent and unable to manage the empire effectively after Mansa Musa’s death.
Succession disputes led to civil wars that weakened the central government.
The once-strong Mali army became weak and ineffective in protecting the empire.

External Factors

The Mali Empire also faced numerous external pressures that contributed to its collapse. Neighboring powers and internal conflicts further destabilized the empire.

These include:

Attacks by the Tuaregs, who captured Walata and Timbuktu in 1433.
Raids by the Mossi on the southern frontiers, disrupting trade and security.
Efforts by emperors to seek Portuguese support failed to yield assistance.
Expansion of the Songhai Empire under Sonni Ali, who captured Mali territories by the 15th century.
By 1670, the Mali Empire had completely disappeared from the map of West Africa.
