The oral history of the Yoruba describes an origin myth, which tells of God lowering a chain at Ile-Ife, down which came Oduduwa, the ancestor of all people, bringing with him a cock, some earth, and a palm kernel. The earth was thrown into the water, the cocked scratched it to become land, and the kernel grew into a tree with sixteen limbs, representing the original sixteen kingdoms. The empire of Oyo arose at the end of the 15th century aided by Portuguese guns. Expansion of the kingdom is associated with the acquisition of the horse. At the end of the 18th century civil war broke out at Oyo, the rebels called for assistance to the Fulani, but the latter ended up conquering all of Oyo by the 1830s. The Fulani invasion pushed many Yoruba to the south where the towns of Ibadan and Abeokuta were founded. In the late 1880s, with the help of a British mediator, a treaty was signed between the various warring factions. Yorubaland was officially colonized by the British in 1901, but a system of indirect rule was established that mimicked the structure of Yoruba governance.
