Burritt founded the peace organization the League of Universal Brotherhood in 1846. He launched it at Pershore, and it was supported by Sturge, James Silk Buckingham, and John Jefferson of the London Peace Society. The Quaker Edmund Fry (1811–1866) became its Secretary, and Charles Gilpin a supporter. Burritt edited the monthly "Bond of Brotherhood", from London. The League promoted the use of free-labour produce. Female auxiliaries, called 'Olive Leaf Circles', raised funds for the League by selling articles made from free-labour cotton and other raw materials. By 1850 there were around 150 of such circles in Britain.
