The history of Christianity in Britain covers the religious organisations, policies, theology and popular religiosity since ancient times. The Roman Catholic Church was the dominant form of Christianity in Britain from the 6th century through to the Reformation period in the Middle Ages. The (Anglican) Church of England became the independent established church in England and Wales in 1534 as a result of the English Reformation. In Wales, disestablishment took place in 1920 when the Church in Wales became independent from the Church of England. In Scotland, the (Presbyterian) Church of Scotland, established in a separate Scottish Reformation in the 16th century, is recognized as the national church, but not established.
