The Oyo Empire was a powerful Yoruba empire of West Africa made up of parts of present-day eastern Benin and western Nigeria (including the Southwest zone and the western half of the Northcentral zone). It grew to become the largest Yoruba-speaking state and rose through the outstanding organizational and administrative skills of the Yoruba people, wealth gained from trade, and its powerful infantry. The Oyo Empire was one of the most politically important states in the entirety of Western Africa from the mid-17th to the late 18th century, and held sway not only over most of the other kingdoms in Yorubaland, but also over nearby African states, notably the Fon Kingdom of Dahomey in the modern Republic of Benin on its west. History Legend of origin The origins of the Oyo Empire lie with Oranyan (also known as Oranmiyan), the last prince of the Yoruba Kingdom of Ile-Ife (Ife). Oranmiyan made an agreement with his brother to launch a punitive raid on their northern neighbors for insulting their father Oduduwa, the first Ooni of Ife. On the way to the battle, the brothers quarreled and the army split up. Oranmiyan's force was too small to make a successful attack, so he wandered the southern shore until reaching Bussa. There, the local chief entertained him and provided a large snake with a magic charm attached to its throat. The chief instructed Oranmiyan to follow the snake until it stopped somewhere for seven days and disappeared into the ground. Oranmiyan followed the advice and founded Oyo where the serpent stopped. The site is remembered as Ajaka. Oranmiyan made Oyo his new kingdom and became the first "oba" (meaning 'king' or 'ruler' in the Yoruba language) with the title of "Alaafin of Oyo" (Alaafin means 'owner of the palace' in Yoruba). He left all his treasures in Ife and allowed another king to rule there. At one time, Oyo-Ile was at war with the Bariba of Borgu, who wanted to subjugate the new city then still under construction. Orangun Ajagunla of Ila, Oranmiyan's elder brother, stormed in with his men to assist. Not long after the war was won, Oranmiyan had a son, Ajuwon Ajaka, by Princess Torosi of the Tapa (Nupe); much later Arabambi was also born by the same woman. It is believed that the name "Sango" was given by his maternal grandfather or that he adopted it from the local
