 The Norman invasion of Wales finally brought Welsh dioceses under England's control.The development of legends about the mission of Fagan and Deruvian and Philip the Apostle's dispatch of Joseph of Arimathea in part aimed to preserve the priority and authority of the native establishments at St David's, Llandaff, and Glastonbury.It was not until the death of Bishop Bernard () that St Davids finally abandoned its claims to metropolitan status and submitted to the Province of Canterbury, by which point the popularity of Geoffrey of Monmouth's pseudohistorical "Historia Regum Britanniae" had begun spreading these inventions further afield.
