There are 42 Church of England dioceses, each being an administrative territorial unit governed by a bishop. These cover England, the Isle of Man, the Channel Islands and a small part of Wales. The Diocese in Europe is also a part of the Church of England, and covers the whole of continental Europe, Morocco and the post-Soviet states. The structure of dioceses within the Church of England was initially inherited from the Catholic Church as part of the Protestant Reformation. During the Reformation a number of new dioceses were founded, but no more were then created until the middle of the 19th century, when dioceses were founded mainly in response to the growing population, especially in the northern industrial cities. The most recent diocese to be established was the Diocese of West Yorkshire and the Dales, which came into being on 20 April 2014. Prior to that, no new dioceses had been founded since 1927. West Yorkshire and the Dales was created by combining three previous dioceses: the Diocese of Bradford, the Diocese of Ripon and Leeds, and the Diocese of Wakefield.
