Oyo Empire

Overview

The Oyo Empire was the great Yoruba empire of West Africa, centred on present-day western Nigeria and Benin. The largest Yoruba-speaking state ever formed, it dominated Yorubaland and much beyond—including the Fon kingdom of Dahomey—from the late 16th to the early 19th century, reaching over 150,000 km² by 1680. Its power rested on cavalry, trade, and an unusually sophisticated constitutional system.

History

Yoruba tradition traces Oyo's founding to Oranmiyan, a prince of Ile-Ife, around 1300; the early kingdom was dominated by Ife and later shattered about 1535, when the Nupe occupied Oyo and drove its dynasty into exile in Borgu for some 80 years. Re-established around 1608 at Oyo-Igboho and then at rebuilt Oyo-Ile, the empire that emerged was centralized and aggressively expansionist: Oba Eguguojo conquered most of Yorubaland, Orompoto broke the Nupe, and by 1600 the Ewe and Aja states paid tribute.

Government balanced the Alaafin ("owner of the palace"), a sacred king chosen by the seven councillors of the Oyo Mesi, against the Ogboni earth-cult society and the war chiefs (Eso) under the Aare-Ona-Kakanfo; an unwanted Alaafin was compelled to ritual suicide by presentation of parrot's eggs. The empire's long arm was its cavalry—over 100,000 horsemen at its height, mounted on horses bought from the north—plus renowned archers; after eleven invasions it finally subjugated Dahomey in 1748. Oyo's wealth came from tribute, agriculture in the tsetse-free northern savanna, control of trade corridors to the coast, and increasingly the Atlantic slave trade. Religion was the Yoruba cult of the orishas—Sango, the deified early Alaafin, above all—with Islam present only at the margins of the court.

Decline and legacy

Decline began with the machinations of Bashorun (prime minister) Gaha, who from 1754 forced four successive Alaafins to suicide before Alaafin Abiodun executed him in 1774. Abiodun's murderer-son Awole provoked the Aare-Ona-Kakanfo Afonja into rebellion; Ilorin seceded in 1817 and, after Afonja's death, became part of the Fulani Sokoto Caliphate in 1823. Dahomey revolted and defeated Oyo in 1823; Ilorin's raids destroyed Oyo-Ile itself in 1835. The capital moved south to Ago d'Oyo (New Oyo), eclipsed by Ibadan; the rump monarchy survived under British colonial rule and continues as a Nigerian traditional state. Oyo's collapse sent waves of Yoruba captives into the Atlantic trade—the Nagô of Brazil and Lucumí of Cuba—whose religions (Candomblé, Santería) preserve Oyo's culture across the Atlantic world.
