Sunni Ali Expands Songhai

Setting the scene

By 1464, the Songhai people controlled a small kingdom around Gao on the Niger River, formerly a vassal of the Mali Empire, which was in decline. Sunni Ali, who became ruler in 1464, was a dynamic military leader who transformed Songhai into an empire. He was a nominal Muslim but practiced traditional African religion, which later Muslim scholars criticized. Sunni Ali built a professional army with cavalry and a navy of canoes to control the Niger River.

What happened

Sunni Ali embarked on a campaign of conquest, capturing the great trading city of Timbuktu in 1468 after a long siege, and Djenné in 1473. He extended Songhai's control along the Niger, conquering the remnants of Mali and dominating trans-Saharan trade in gold, salt, and slaves. He ruled for 28 years, creating an empire stretching 1,000 miles along the Niger. His military tactics included surprise attacks and using the river for mobility. He was known for his ruthlessness—he reportedly drowned scholars who opposed him in Timbuktu.

Why it still matters

Sunni Ali's conquests (1464-1492) created the Songhai Empire, which became the largest empire in African history, surpassing Mali. At its peak under his successor Askia Muhammad, Songhai controlled territory larger than Western Europe. Sunni Ali demonstrated how control of the Niger River and trans-Saharan trade routes could build wealth and power in West Africa. His empire fostered Islamic scholarship in Timbuktu, which became a center of learning. Songhai's fall to Morocco in 1591 ended the era of great West African empires. Sunni Ali is remembered as a brilliant but brutal conqueror who made Songhai a major power.

Background

Timbuktu became famed for scholarship and manuscript culture under later rulers. Even centuries later, this episode remains a reference point for how empires rise, fracture, and transform.
