Samuel Crowther, was a Yoruba linguist, clergyman, and the first African Anglican bishop of West Africa. Born in Osogun, he and his family were captured by Fulani slave raiders when he was about twelve years old. This took place during the Yoruba civil wars, notably the Owu wars of 1821–1829, where his village Osogun was ransacked. Ajayi was later on resold to Portuguese slave dealers, where he was put on board to be transported to the New World through the Atlantic.
