The Kingdom of Bonny is a traditional state based on the town of Bonny in Rivers State, Nigeria. In the pre-colonial period, it was an important slave trading port, later trading palm oil products. During the 19th century the British became increasingly involved in the internal affairs of the kingdom, in 1886 assuming control under a protectorate treaty. Today the King of Bonny has a largely ceremonial role.
The unstable balance of power within Bonny deteriorated. On 14 December 1883 King George was deposed. Bonny Chiefs with Naval Commandant 1896. The next year Oko Jumbo fell out with the other chiefs in Bonny. There were rumors that he wanted to place one of his sons on the throne, although a planned coup attempt in January 1885 came to nothing. Another son, Herbert Jumbo, who had been educated in England, quarreled with his father and placed himself under the protection of the British consul.
In February 1886 a protectorate treaty was concluded between Bonny and Britain. A ruling council was established, and King George Pepple was restored to his throne. Oko Jumbo was publicly degraded, his bans on Christianity were repealed and afterwards he was a spent force in Bonny politics.
King George died in October 1888, and was succeeded by a series of regents, kings and at one time a Chiefs Council before Edward Asimini William Dappa Pepple III (Perekule XI) took the throne in 1996.
