Catholic Church in the United Kingdom
In the United Kingdom, the Catholic Church is organised into the Catholic churches in England and Wales, Scotland, and with Northern Ireland organised as part of the Catholic Church in Ireland, all as part of the worldwide Catholic Church in communion with the Bishop of Rome (the pope). While there is no ecclesiastical jurisdiction corresponding to the United Kingdom as a whole, this article refers to the Catholic Church's geographical representation in Great Britain and Northern Ireland, ever since the establishment of the Kingdom of Great Britain by the Acts of Union 1707, and later the United Kingdom.
