 Oyo sources claim Ketu as a dependency with claims that the Ketu paid an annual tribute and that its ruler attended the Bere festival in Oyo.In any case, there is no doubt that Ketu and Oyo maintained friendly relations largely due to their historical, linguistic, cultural and ethnic ties.The kingdom was one of the main enemies of the ascendant kingdom of Dahomey, often fighting against Dahomeans as part of Oyo's imperial forces, but ultimately succumbing to the Fon in the 1880s as the kingdom was ravaged.
