The Edwardian Reformation was quickly overturned when Mary Tudor succeeded her half-brother and began returning the English Church to Rome. The printers of the Edwardian prayer books had their businesses placed under Catholic managers, and all Edwardian prayer books were called in to be burnt. When Mary died and was succeeded by Elizabeth, the influence of Catholic bishops and abbots in the House of Lords was a major obstacle to any revival of the Reformation. Eventually, however, the passage of an Act of Supremacy made Elizabeth Supreme Governor of the Church of England, and a new Act of Uniformity prescribed a Book of Common Prayer that largely revived the 1552 book but with a few significant revisions. Two editions were put in hand, one supervised by the two new Queen’s Printers (Richard Jugge and John Cawood) and the other by Richard Grafton (who had taken back control of his printing house).
