The Province of Canterbury, also called the Southern Province, is one of two ecclesiastical provinces which comprise the Church of England. (The other is the Province of York.) It consists of 30 dioceses, covering roughly the southern two-thirds of England, parts of Wales, and the Channel Islands, with the remainder comprising continental Europe (under the jurisdiction of the Diocese of Gibraltar in Europe).
Historically, between the years 787 and 803, a third Province was formed: the Province of Lichfield. In 1871, the Church of Ireland became autonomous, and the Church in Wales was disestablished in 1920.
The Province's metropolitan bishop is the Archbishop of Canterbury who still oversees the Falkland Islands, an extra-provincial parish.
