Wesleyan missionary work was begun at Sierra Leone coincidently with the establishment of that place as a settlement for freed slaves in 1787. The London Missionary Society was founded in 1795, and the Edinburgh Missionary Society in 1796; the Glasgow Missionary Society soon afterwards. By the end of the 18th century these three bodies had sent out missionaries to Sierra Leone and the adjoining Susu country. In 1821 the Glasgow Missionary Society sent the first Presbyterian missionaries to South Africa. The Church Missionary Society was founded in 1799. It furnished missionaries for Sierra Leone, and after a long interval extended its operations to Lagos and the Niger Delta, where it is still the leading Christian mission. In 1830 this mission sent its first agents to teach Protestant Christianity in Abyssinia, and began to consider the possibility of evangelizing East Africa. In common with other English missionary societies at that time, and for reasons not altogether clear, it preferred to employ German evangelists, though from the results achieved few can find fault with the choice made. The Church Missionary Society introduced to us men of the stamp of Krapf and Rebmann. Dr Ludwig Krapf is justly a great name in African exploration, African philology, and African Christianity. Despatched by the Church Missionary Society to prospect Abyssinia in 1834, he was obliged to decide in 1842 (in Shoa), after disappointing experiences, that there was no field there for Protestant Christianity, and therefore directed his steps to the Zanzibar coast. Being a tactful man, and meeting with kindness at the hands of Sayyid Sa’id, the ‘Sultan’ of Zanzibar[136], he established himself at Rabai, near Mombasa, and there founded the work of the Church Missionary Society, which endures and prospers to this day. Dr Krapf will also be referred to in the chapter on explorers. The Church Missionary Society educated the first Protestant negro bishop[137] in the person of Samuel Crowther of the Niger. Its work met with some success on the West Coast of Africa as regards the number of adherents; but, like most Christian missions, it has not achieved rapid progress in more or less Muhammadanized East Africa. This mission stands out conspicuous for the magnificent philological work done by its agents in Africa; especially notable among whom have been Dr S. W. Koelle, Mr Reichardt, the Rev. James Frederic Schön, Bishop Crowther, Krapf, Rebmann, and J. T. Last.
