The Oxford Movement was a movement of high church members of the Church of England which began in the 1830s and eventually developed into Anglo-Catholicism. The movement, whose original devotees were mostly associated with the University of Oxford, argued for the reinstatement of some older Christian traditions of faith and their inclusion into Anglican liturgy and theology. They thought of Anglicanism as one of three branches of the "one, holy, catholic, and apostolic" Christian church. Many key participants subsequently converted to Roman Catholicism.

The movement's philosophy was known as Tractarianism after its series of publications, the Tracts for the Times, published from 1833 to 1841. Tractarians were also disparagingly referred to as "Newmanites" (before 1845) and "Puseyites" (after 1845) after two prominent Tractarians, John Henry Newman and Edward Bouverie Pusey. Other well-known Tractarians included John Keble, Charles Marriott, Richard Froude, Robert Wilberforce, Isaac Williams and William Palmer. All except Williams and Palmer were fellows of Oriel College, Oxford.
