Sotouba Falls occupied a decisive position in the rivalry between Songhay and Mali. Situated upstream from Bamako, they lay between the Songhay fleet and the heart of Malinke country. This geographical barrier prevented Songhay from extending its riverine military power directly into Mali’s southern core.

The falls also had wider political significance. When Mali was at its height, they divided the empire in two, separating Malinke country from conquered lands. The Niger waterway therefore could not foster unity and central authority in Mali as effectively as it did in Songhay.

During the sixteenth century Sotouba Falls protected Mali and marked the south-western limit of Songhay expansion. Their strategic importance helps explain why Songhay relied on repeated raids and frontier interventions rather than a straightforward conquest of the Malinke heartland.
