The Oxford Movement was a theological 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 Catholicism.
