The English Reformation was a series of events in 16th century England by which 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 process of the European Protestant Reformation, a religious and political movement that affected the practice of Christianity across western and central Europe during this period. Many factors contributed to the process: the decline of feudalism and the rise of nationalism, the rise of the common law, the invention of the printing press and increased circulation of the Bible, and the transmission of new knowledge and ideas among scholars, the upper and middle classes and readers in general. However, the various 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.
Based on Henry VIII's desire for an annulment of his marriage (first requested of Pope Clement VII in 1527), the English Reformation was at the outset more of a political affair than a theological dispute. The reality of political differences between Rome and England allowed growing theological disputes to come to the fore. Until the break with Rome, it was the Pope and general councils of the Church that decided doctrine. Church law was governed by canon law with final jurisdiction in Rome. Church taxes were paid straight to Rome, and the Pope had the final word in the appointment of bishops.
The break with Rome was effected by a series of acts of Parliament passed between 1532 and 1534, among them the 1534 Act of Supremacy, which declared that Henry was the "Supreme Head on earth of the Church of England". (This title was renounced by Mary I in 1553 in the process of restoring papal jurisdiction; when Elizabeth I reasserted the royal supremacy in 1559, her title was Supreme Governor.) Final authority in doctrinal and legal disputes now rested with the monarch, and the papacy was deprived of revenue and the final say on the appointment of bishops.
