English Reformation [SEP] Introduction
The English Reformation took place in 16th-century England when the Church of England broke away from the authority of the Pope and the Roman Catholic Church. These events were, in part, associated with the wider European Protestant Reformation, a religious and political movement that affected the practice of Christianity in western and central Europe. Causes included the invention of the printing press, increased circulation of the Bible and the transmission of new knowledge and ideas among scholars, the upper and middle classes and readers in general. The phases of the English Reformation, which also covered Wales and Ireland, were largely driven by changes in government policy, to which public opinion gradually accommodated itself.
