Defender of the Faith (Fidei Defensor or, specifically feminine, Fidei Defensatrix; Défenseur de la Foi) is a phrase that has been used as part of the full style of many English, Scottish, and later British monarchs since the early 16th century. It has also been used by some other monarchs and heads of state. The earliest use of the term appears in 1507, when King James IV of Scotland was granted the title of "Protector and Defender of the Christian Faith" by Pope Julius II. The title was conferred on James IV by the papal legate Robert Bellenden in a lavish ceremony in Holyrood Abbey. "Defender of the Faith" has been one of the subsidiary titles of the English and later British monarchs since it was granted on 11 October 1521 by Pope Leo X to King Henry VIII. His wife Catherine of Aragon also used the title. The title was conferred in recognition of Henry's book Assertio Septem Sacramentorum (Defence of the Seven Sacraments), which defended the sacramental nature of marriage and the supremacy of the pope. This was also known as the "Henrician Affirmation" and was seen as an important opposition to the early stages of the Protestant Reformation, especially the ideas of Martin Luther. Following Henry's decision to break with Rome in 1530 and establish himself as head of the Church of England, the title was revoked by Pope Paul III and he was excommunicated. However in 1543 the Parliament of England conferred (by a bill entitled "The Bill for the Kinges Stile") on King Henry VIII and his successors, now the defenders of the Anglican faith, the style "Henry the Eighth by the Grace of God King of England, France and Ireland, Defender of the Faith and of the Church of England and also of Ireland in Earth the Supreme Head". All subsequent monarchs (except the Catholic Queen Mary I) became supreme governors. King James V of Scotland was granted the title of "Defender of the Faith" by Pope Paul III on 19 January 1537, symbolizing the hopes of the papacy that the King of Scots would resist the path that his uncle Henry VIII had followed.
