The Oxford Movement was a religious movement within the Church of England, based at the University of Oxford, which began in 1833. Members of this movement were known as 'Tractarians' (from "Tracts for the Times", a collection of books, pamphlets and essays that described their beliefs); opponents of the movement called them Newmanites (before 1845) and Puseyites (from 1845), after John Henry Newman and Edward Bouverie Pusey, two leading Tractarians. The members of the movement tried to bring back Catholic doctrine and forms of service (how Sunday services and other forms of worship were carried out in Anglican churches, the Oxford Movement wanting to make these more like a Catholic Mass) into the Church of England. They also believed the Anglican church was an 'apostolic' church, connected directly to the Church of Saint Peter and the other Apostles. John Keble was another leader of the movement.
