After the death of Henry VIII, the Court moved quickly to create a powerful evangelical reform party that establish it's supremacy using the youth of the next king, Edward VI, son of Henry VIII and Jane Seymour. During his reign, there was a very strong attempt to introduce a full Protestant church polity in England. It was to be modeled like that which was in place in Swiss and German churches. The attempt was driven by Archbishop Cranmer and the Lord Protector, the Duke of Somerset. During the five years of Edward's reign, many reforms took place: two evangelical prayer books, a new order of English service, and the stripping of remaining Catholic paraphernalia. Edward died in 1553, and was succeeded by Catholic his half-sister, Mary I.
