The Empire of Songhai Was Originally Part of What Empire?

The Empire of Songhai was originally part of the Mali Empire, the West African power that dominated the Sahel from roughly the 13th to the 15th century. Songhai began as a small kingdom centered on the city of Gao, a trading town on the Niger River, and it existed under Mali’s authority as a subject province before breaking away and building an empire of its own. So the short answer is Mali — not Ghana, which rose and fell before Mali took its place.

The Empire of Songhai Was Originally Part of Mali

The Songhai state grew out of Gao, a settlement on the eastern bend of the Niger River in what is now Mali. Gao became an important commercial hub because it sat at the crossroads of trans-Saharan trade routes, linking the gold and goods of the forest regions to the salt and markets of the desert. That commercial position gave the early Songhai rulers both wealth and ambition.

During the 13th century, the Mali Empire — founded by Sundiata Keita and later famous for the pilgrimage of Mansa Musa — expanded eastward and absorbed Gao. According to Encyclopaedia Britannica, Mali’s authority extended over the Songhai kingdom, and the rulers of Gao were drawn into Mali’s political orbit. For a period, Songhai functioned as a vassal or tributary state, paying deference to Mali’s mansa (king) while keeping its own local dynasty.

That relationship lasted for generations, but it was never entirely stable. As Mali’s central power weakened in the 14th and 15th centuries, the Songhai rulers at Gao saw an opening.

Mali at Its Height

Mali was one of the wealthiest states of the medieval world. Its cities, especially Timbuktu and Djenné, became centers of learning and trade. The Metropolitan Museum of Art’s Heilbrunn Timeline notes that Mali’s control of trans-Saharan commerce made it a dominant force across West Africa. Absorbing Gao was part of that broader expansion — Mali wanted the Niger River trade, and Gao was a key node in it.

From Gao to Mali’s Orbit

Gao’s earliest dynasty, often referred to as the Za or Dia line of rulers, governed the town before Mali’s rise. When Mali’s armies moved east, Gao was conquered and placed under Mali’s suzerainty. The local Songhai rulers continued to govern on the ground, but they recognized Mali’s overlordship and, at times, paid tribute.

This arrangement was typical of how Mali managed its sprawling territory. Rather than ruling every province directly, Mali often left local elites in place as long as they acknowledged the mansa’s authority and kept trade flowing. Gao fit that pattern: it kept its own rulers, its own commercial life, and a degree of autonomy, but it was politically subordinate.

Over time, Mali’s grip loosened. Succession disputes, the rise of rival powers, and the sheer difficulty of governing a vast empire from a distant capital all eroded Mali’s control over its eastern provinces. Gao was far from Mali’s core, and distance made obedience harder to enforce.

A Province Under Pressure

As Mali weakened, Gao’s rulers grew bolder. They began to assert independence, and the relationship shifted from subordination toward rivalry. This is the hinge on which Songhai’s rise turned — a subject province recognizing that its overlord could no longer compel loyalty.

Breaking Free and Rising

Songhai’s decisive break came in the 15th century under Sunni Ali, who became ruler of Gao in 1464. Sunni Ali launched a series of campaigns that expanded Songhai’s territory, seizing Timbuktu in 1468 and Djenné later, and turning a former vassal state into an empire that eclipsed Mali. The very cities that had symbolized Mali’s greatness became prizes of Songhai’s expansion.

Sunni Ali’s successors continued the work. His son Sonni Baru was overthrown by Askia Muhammad, who founded the Askia dynasty and further consolidated the empire. Under Askia Muhammad, Songhai reached its greatest extent, controlling a huge stretch of the Sahel and dominating the trans-Saharan trade that Mali had once controlled.

By the 16th century, Songhai was the largest empire in West African history, and Mali had been reduced to a much smaller, weaker state on its western periphery — a striking reversal of the earlier relationship. Gao, once a tributary town, was now an imperial capital. The UNESCO World Heritage Centre recognizes Gao and the wider region for its archaeological and historical importance, reflecting the deep roots of this imperial story.

A Worked Example of the Reversal

Consider Timbuktu. Under Mali, it flourished as a center of scholarship and trade, a jewel of the mansa’s realm. When Sunni Ali took it in 1468, it became a Songhai city — and under Askia Muhammad it continued to thrive. The same city that marked Mali’s cultural height became a pillar of Songhai’s power, illustrating how completely the former subject had overtaken its old master.

Why the Mali Connection Matters

Understanding that Songhai began as part of Mali clarifies a common point of confusion. People often mix up West Africa’s three great medieval empires — Ghana, Mali, and Songhai — because they rose in overlapping regions and traded through many of the same routes. But their sequence is distinct:

• Ghana was the earliest of the three, flourishing roughly from the 8th to the 11th century.
• Mali rose after Ghana’s decline, reaching its height in the 13th and 14th centuries.
• Songhai emerged from Gao, was absorbed by Mali, then broke free and became the last and largest of the three.

Because Ghana came first, some mistakenly describe Songhai as having grown out of Ghana. That is not correct. Ghana had already declined before Songhai’s rise, and Songhai’s direct political subordination was to Mali. The chain runs Ghana, then Mali, then Songhai — with Songhai specifically emerging as a Malian province before asserting independence.

This lineage also explains why the three empires are often studied together: they shared geography, trade networks, and institutions. Songhai inherited much of Mali’s administrative and commercial world, even as it replaced Mali as the dominant power. Its origins as a Malian vassal are not a footnote — they are central to how it became an empire.

Key Takeaways

• Songhai was originally part of the Mali Empire, not Ghana.
• Songhai began as the kingdom of Gao, a Niger River trading town.
• Mali absorbed Gao around the 13th century, ruling it as a vassal or tributary province.
• As Mali weakened, Gao asserted independence, and Sunni Ali (from 1464) turned Songhai into a major empire.
• Songhai eventually surpassed and eclipsed Mali, reversing their original relationship.
• The three great empires ran in sequence: Ghana → Mali → Songhai.
