Jaja of Opobo

Jaja led a secession of Bonny's Anna Pepple house to establish the independent city-state of Opobo in the Niger Delta. He declared himself king and built a new trading center that rivaled Bonny in palm oil exports.

Jaja established a monopoly over palm oil trade in the Opobo region, controlling prices and excluding European merchants from direct access to producers. This gave him significant economic power and wealth.

Jaja resisted British attempts to impose treaties that would limit his sovereignty and trade control. He refused to sign the 1884 Treaty of Protection, asserting Opobo's independence and challenging British imperial expansion.

British consul Harry Johnston tricked Jaja into negotiations and arrested him. Jaja was tried by a British court, deposed, and exiled to Saint Vincent in the West Indies, ending his rule over Opobo.

After years of exile, Jaja was allowed to return to West Africa but died en route, possibly poisoned. His death marked the end of organized resistance to British control in the Niger Delta palm oil trade.
