From the early 19th to the mid-20th century Methodism was the leading form of Christianity in Cornwall but it is now in decline. The Church of England was in the majority from the reign of Queen Elizabeth until the Methodist revival of the 19th century: before the Wesleyan missions dissenters were very few in Cornwall. The county remained within the Diocese of Exeter until 1876 when the Anglican Diocese of Truro was created (the first Bishop was appointed in 1877). Roman Catholicism was virtually extinct in Cornwall after the 17th century except for a few families such as the Arundells of Lanherne. From the mid-19th century the church reestablished episcopal sees in England, one of these being at Plymouth. Since then immigration to Cornwall has brought more Roman Catholics into the population.
