The London Missionary Society was a missionary society formed in England in 1795 by evangelical Anglicans and various nonconformists. It was largely Reformed in outlook, with Congregational missions in Oceania and Africa, although there were also Presbyterians (notable for their work in China), Methodists, Baptists and various other Protestants involved. It now forms part of the Council for World Mission (CWM).
As early as 1793, Edward Williams, then minister at Carr's Lane, Birmingham, had written a letter to the churches of the Midlands, expressing the need for world evangelization and foreign missions. It was an effective letter; Williams began to play an active part in the plans for a missionary society. Williams left Birmingham in 1795, becoming pastor at Masbrough, Rotherham, and tutor of the newly formed Masbrough academy. He continued his involvement with the Society and, in July 1796, it was he who gave the charge to the first missionaries sent out by the Society.
Proposals for the Missionary Society began in 1794 after a Baptist minister, John Ryland, received word from William Carey, the pioneer British Baptist missionary who had recently moved to Calcutta, about the need to spread Christianity. Carey suggested that Ryland join forces with others along the non-denominational lines of the Anti-Slavery Society to design a society that could prevail against the difficulties that evangelicals often faced when spreading the Word. This aimed to overcome the difficulties that establishment of overseas missions had faced. It had frequently proved hard to raise the finance because evangelicals belonged to many denominations and churches; all too often their missions would only reach a small group of people and be hard to sustain.
