Church reform in the 16th century was influenced by earlier movements such as the Waldensians, Lollards, and Hussites, who criticized the Catholic Church. Martin Luther furthered reform with his 95 Theses and writings on "Sola Fide". In England, King Henry VIII broke with Rome over his divorce and passed acts establishing himself as the head of the Church of England. Under Edward VI and Elizabeth I, further reforms through acts of uniformity and the Book of Common Prayer standardized Protestant theology, though reform remained an ongoing process.
