The case for narrating the history of slavery and emancipation through the biography of enslaved Africans is strongly supported by the life and experiences of Samuel Ajayi Crowther. Kidnapped into slavery in 1821, recaptured and settled in Sierra Leone in 1822, he became a missionary in 1845, founder of the Niger mission in 1857, and Bishop of the Niger Mission in 1864. His life and career covered the span of the 19th century during which revolutionary forces like jihadist revolutions, the abolition of the slave trade, the rise of a new Westernized elite, and European colonization created the roots of the modern state system in West Africa. He was intricately tied to the Christian Missionary Society (CMS), Britain’s antislavery evangelical movement, resulting in Ajayi becoming the poster face of slavery, its acclaimed product of abolitionism, the preeminent advocate of evangelical emancipation, and the organizer of practical emancipation in West Africa. The leader of a very small group of Africans who worked diligently against the slave trade and domestic slavery, Ajayi also became a victim of the use of that agenda by imperialists. Thus, the contrasts of his life (i.e., slavery/freedom, nationalist/hybrid, preacher/investor, leader/weakling, linguist/literalist, etc.) were celebrated by himself, his patrons, and his evangelical followers on one hand, and denounced by his critics on the other. They underline the disagreements over his legacy, and indeed over the understanding of the institution of slavery, abolition, and emancipation in West Africa.
