The Songhai Empire: West Africa's Last Great Sahelian Power

Songhai was the last of the three great trading empires to dominate the West African Sahel, following Ghana and Mali, and by most accounts the most militarily powerful of the three. Its territory is commonly estimated at somewhere between 800,000 and 1.4 million square kilometers depending on the year measured, figures that trace back to a widely used but imprecisely sourced comparative dataset rather than to a single agreed academic measurement; treat any of these numbers as an estimate, not a precise fact.

Songhai existed as a smaller kingdom centered on the Niger River city of Gao for centuries before its imperial expansion, but it was Sonni Ali, who ruled from around 1464 to 1492, who transformed it into a genuine empire, and his successor’s dynasty that brought it to its height. Sonni Ali was deposed shortly after his death by one of his commanders, who took power as Askia Muhammad I and founded the Askiya dynasty that would rule Songhai for the rest of its existence. Under Askia Muhammad, who reigned from 1493 to 1529, Songhai reached its greatest extent, incorporating the Niger Bend’s two most important cities, Timbuktu and Djenné, centers of trans-Saharan commerce and of Islamic scholarship that had also been prizes of the earlier Ghana and Mali empires.

Songhai’s rulers were not without turbulence: of the nine Askiya-dynasty rulers who followed Askia Muhammad, a majority were either deposed in rebellions or died violent deaths, a pattern of instability common to trans-Saharan trading empires whose wealth made the throne worth fighting over. The empire nonetheless held together as the dominant regional power for over a century, until Morocco’s Sultan Ahmad al-Mansur, eager to control the same gold and salt trade routes, sent an invasion force of roughly 4,000 troops under Judar Pasha north across the Sahara in 1591.

The two armies met at the Battle of Tondibi on March 13, 1591. Songhai fielded a far larger force, cited variously at around 30,000 infantry and 10,000 cavalry, but its conventional weapons were no match for Moroccan matchlocks and light cannon; accounts describe gunpowder fire triggering a stampede among Songhai’s cattle that broke its own lines before the battle was even properly joined. The empire collapsed rapidly afterward, fragmenting into smaller successor states, though surviving members of the Askiya dynasty continued a much-reduced kingdom in the Dendi region for another three centuries, not conquered by France until 1901.
