After the conclusion of the Napoleonic Wars, the Court of Vice-Admiralty at Sierra Leone lost its place at the centre of the colonial economy. Former slaves released from the slave trade by the Court, and by its successor, the Courts of Mixed Commission, became the focus of intense attention from colonial officials and missionaries. Governor Charles MacCarthy, in conjunction with the Church Missionary Society, established a network of villages, the Liberated African Villages, scattered around the colony. The villages were the site of a sustained civilizing mission, which helped MacCarthy and other colonial officials to organise labour in the colony, to attract investment from Britain, and to expand Britain’s territory in West Africa. Under MacCarthy, British antislavery transformed into colonialism, as ‘captured Negroes’ became ‘Liberated Africans.’ The chapter also explores the relationship between Sierra Leone and the American colony of Liberia.
