Who is Sonni Ali?

Sonni Ali, also known as Sonni Ali Ber ("Ali the Great"), was the warrior-king who took a small tributary state on the Niger River and forged it into the Songhai Empire, the largest empire in African history, by seizing the very cities at the center of this conversation: Timbuktu, Djenné and Gao.

Their story

When Sonni Ali ascended the Songhai throne around 1464, the kingdom comprised only a small area in the upper Niger valley around its capital, the prosperous trading city of Gao. The Mali Empire, which we have been tracing throughout this conversation, was fracturing. The Songhai people had managed to throw off the domination of the Mali Empire, and hoped to obtain territorial benefits, like other West African peoples, from its disintegration.

Sonni Ali was born the son of Sonni Muhammad Daʾo. His mother was from Fara, an area that was still heavily pagan, and Ali was raised in this milieu. As a Sonni, he also received an Islamic Mediterranean education, but practiced a syncretic, unorthodox faith. That mixed inheritance, warrior tradition on one side and Islamic schooling on the other, defined both his power and the controversy that followed him.

What he achieved

Around 1468, Sonni Ali changed the traditional Songhai tactic of small and sporadic raids on its enemies to a more sustained campaign of permanent territorial expansion. With an army equipped with armored cavalry and the only naval fleet in North Africa, which he deployed on the Niger River, he was able to conquer the rump of the old Mali Empire.

The two conquests that mattered most to this story are Timbuktu and Djenné.

His first major conquest was the ancient city of Timbuktu Djenn. Controlled by the Tuareg since the Malian Empire retreat a few decades earlier, in 1469 the Timbuktu-koi ʿUmar asked for Songhai protection. Sonni Ali answered with an army and took the city.

Djenné, the crossroads market hub we just covered, was harder. Aware of the benefits of controlling Sudanese commerce, Sonni Ali turned to the conquest of the wealthy trading city of Djenné on the Bani River near its confluence with the Niger. His seven-year siege of the city resulted in its conquest in 1473. Seven years to take one city tells you how valuable the prize was.

He effectively mixed leniency, with conquered warriors invited to join his own army, with complete ruthlessness, infamously executing many of the particularly resistant Fulbe tribe. Hence the king earned his epithet, "Sunni the Merciless."

Little is known about the actual administration of Songhai during Sonni Ali's time except that he divided conquered territories into provinces and appointed trusted lieutenants to govern them.

The controversy that defined his legacy

The ulama, Islamic scholars, disapproved of the way that Sonni Ali mixed traditional religious practices with Islam. They eventually declared that Sonni Ali was not a Muslim and could not be the rightful ruler. This was not a minor theological dispute. The scholars of Timbuktu, who ran the intellectual institutions Mansa Musa had built, became his enemies, and their chronicles shape how history remembered him. Their hostility colored almost everything written about him in the primary Arabic sources.

The Timbuktu chronicle, the Tarikh al-Sudan, notes that the Songhai king played on his image as a magician of the indigenous animist religion to strike fear into his enemies. Whether that was genuine belief or calculated theater, it worked.

What came after him

On his return from an expedition against the Gurma in late 1492, Ali died, possibly drowning while crossing a river. He was succeeded by his son, Baru, who tried to reject all Islamic influence, and was therefore felled by a Muslim-sanctioned coup led by Askia Muhammad within 4 months.

Under the rule of Sonni Ali, the Songhai had surpassed the Malian Empire in area, wealth, and power, absorbing vast regions of the Mali Empire. The man who replaced his son, Askia Muhammad I (also called Askia the Great), would consolidate what Sonni Ali had seized by force and turn it into the administrative empire the history books remember. But none of that was possible without Sonni Ali first taking Timbuktu, Djenné and Gao and making them one.

The ancient Greeks were voracious borrowers. Their debt to Africa was enormous and openly acknowledged by the Greeks themselves. Thales of Miletus, credited as the first Greek philosopher, studied geometry in Egypt. Pythagoras spent years there. Plato visited.
