11th century – 15th century
Upper Guinea coast, from the Gambia to Sierra Leone
The Manden westward expansion was a prolonged movement of Malinke-speaking agricultural settlers, dynastic migrants, merchants, and conquering forces from the inland Nigerian-Sudanese zone toward the Atlantic coast. Beginning by the twelfth century, it brought Manden communities into Senegambia, Guinea-Bissau, Guinea, Sierra Leone, Liberia, and adjacent regions. The expansion was linked to collateral succession, trade, settlement opportunities, and the political growth of Mali. It reshaped coastal societies and established Mali’s access to the Atlantic.

The Story
Manden movement toward the Atlantic began as a gradual process rather than a single campaign. Oral traditions from the Gambia, Casamance, and Guinea-Bissau place agricultural settlement in the late twelfth century, while other communities moved westward with families in search of land, commercial opportunities, and political autonomy. The movement connected inland societies to the estuaries and river systems of the Upper Guinea coast.
Political institutions within Manden society helped propel this expansion. Because collateral succession could prevent many sons of rulers from inheriting their fathers’ positions, some established new states farther west with their families and followers. Merchants also participated, seeking access to Atlantic commerce and productive settlement zones. The expansion therefore combined dynastic competition, migration, agriculture, and trade.
The military dimension became especially visible with the campaigns of Tirmaghan Traore, described as one of Sundiata’s generals. Manden conquest of coastal areas gave Mali broad access to the sea by the late fifteenth century and helped place the region between the Gambia and Sierra Leone under its influence. Yet the resulting political order depended on interaction with existing coastal peoples rather than on military conquest alone.
