Unlike other reform movements, the English Reformation began by royal influence. Henry VIII considered himself a thoroughly Catholic King, and in 1521 he defended the papacy against Luther in a book he commissioned entitled, "The Defense of the Seven Sacraments", for which Pope Leo X awarded him the title "Fidei Defensor" (Defender of the Faith). However, the king came into conflict with the papacy when he wished to annul his marriage with Catherine of Aragon, for which he needed papal sanction. Catherine, among many other noble relations, was the aunt of Emperor Charles V, the papacy's most significant secular supporter. The ensuing dispute eventually lead to a break from Rome and the declaration of the King of England as head of the English (Anglican) Church. England then experienced a period of frenetic and eclectic reforms, some more radical and others more traditional, under monarchs such as Edward VI and Elizabeth I, and Archbishops of Canterbury such as Thomas Cranmer and William Laud. What emerged was a state church that considered itself both "Reformed" and "Catholic" but not "Roman" (and hesitated from the title "Protestant"), and other "unofficial" more radical movements such as the Puritans.
