Samuel Ajayi Crowther was a Church Missionary Society (CMS) missionary bishop charged with evangelizing the territories that became modern Nigeria. Over the last decades of the 19th century Crowther was the best-known Christian of African descent in the British empire. Pious offerings from British Christians allowed him to build a network of mission stations and schools in the Niger bishopric, as his territories were called. Crowther’s career ended in tragedy with a group of English CMS missionaries that traveled to his bishopric to dismiss as either corrupt or immoral most of the African missionary agents Crowther had recruited over the decades. Crowther resigned his office in protest against what he felt was the usurpation of his authority. Crowther died a short time later. Most of the historical scholarship since Crowther’s death (1891) has been concerned with assessments of two things: Crowther’s missionary strategies and the circumstances behind the events at the end of his career. The events at the end of his life have drawn the greatest amount of attention, but as argued in this article, Crowther is better appreciated for the revolutionary ways in which he rethought the missiological ideas of Henry Venn, his patron and mentor, and applied these ideas to the evangelization of his territories. The schools established under Crowther’s direction offered students a combination of skills aimed at making those students competitive in the society created by the expansion of British overrule in the lands that became Nigeria. The appeal of his schools drew many Africans toward the Anglican Church. By the end of his life, however, Crowther’s schools were coming under increasing criticism from Europeans for making Africans too competitive with Europeans.
