What happened
The Songhai kingdom, centered on the Niger River bend near Gao since at least the 9th century CE, expanded dramatically under King Sunni Ali, who reigned from 1464 to 1492. Around 1468 Sunni Ali abandoned Songhai's older pattern of small, sporadic raiding for sustained territorial conquest, using an army with armored cavalry and the only naval fleet on the Niger River to seize the fading remnants of the Mali Empire, including Timbuktu and Djenne. Sunni Ali observed Islamic practices like the Ramadan fast for political convenience rather than conviction, reportedly also sacrificing animals to trees and supporting pagan sorcerers, and he showed no mercy toward Muslims he judged politically threatening. By his death, Songhai had absorbed the trade centers that once made Mali rich and become the dominant power of the Sahel.
Why it matters
Sunni Ali's conquests made Songhai, not Mali, the largest state in West African history, and his combination of cavalry with a river-based naval fleet was a genuinely novel military model in the region, one that let him project power along the Niger in a way no earlier Sahelian ruler had managed.
How we know
The World History Encyclopedia's account draws on the Timbuktu Chronicles (Tarikh al-Sudan and Tarikh al-Fattash), West African Arabic-language histories written by Timbuktu scholars in the following century, which are themselves more critical of Sunni Ali's religious ambivalence than of his military record.
