What happened
Oral tradition traces Oyo's founding to Oranmiyan, a son of Oduduwa, the legendary founder of Ife, who became the first Alaafin, or king, of Oyo. The Oyo Empire flourished from roughly the 17th to the 19th century CE in what is now southwest Nigeria, forging its power through a formidable cavalry and archer force that let its rulers dominate other Yoruba peoples and eventually conquer 13 rival kingdoms. With its capital at Old Oyo near the Niger River, the empire prospered on regional trade and became a central organizer moving captives from Africa's interior toward coastal ports, where Europeans purchased them for the Atlantic trade. Oyo's power began to crack in the 1820s CE when Fulani forces from the expanding Sokoto Caliphate conquered its northern territory of Ilorin, triggering a collapse that left the empire broken into small rival chiefdoms by the mid-19th century.
Why it matters
Oyo shows how a Yoruba state built on cavalry, not coastal contact, became one of the most important suppliers feeding the transatlantic slave trade at the coast, organizing captive transport deep in the interior rather than merely selling at the shore. Its collapse under Fulani pressure from the north also demonstrates how the same 19th-century Islamic expansion that created the Sokoto Caliphate reshaped power balances across the whole region, not just in the Hausa north.
How we know
Oyo's political and military history survives through Yoruba oral tradition maintained by court historians, cross-checked against European trade records documenting captive shipments from Oyo-controlled ports, and archaeological evidence from the Old Oyo capital site.
