Style and arms

Many changes were made to the royal style during his reign. Henry originally used the style "Henry the Eighth, by the Grace of God, King of England, France and Lord of Ireland ". In 1521, pursuant to a grant from Pope Leo X rewarding Henry for his Defence of the Seven Sacraments, the royal style became "Henry the Eighth, by the Grace of God, King of England and France, Defender of the Faith and Lord of Ireland". Following Henry's excommunication, Pope Paul III rescinded the grant of the title "Defender of the Faith", but an Act of Parliament (35 Hen. 8. c. 3) declared that it remained valid; and it continues in royal usage to the present day, as evidenced by the letters FID DEF or F.D. on all British coinage. Henry's motto was "Coeur Loyal" ("true heart"), and he had this embroidered on his clothes in the form of a heart symbol and with the word "loyal". His emblem was the Tudor rose and the Beaufort portcullis. As king, Henry's arms were the same as those used by his predecessors since Henry IV: Quarterly, Azure three fleurs-de-lys Or (for France) and Gules three lions passant guardant in pale Or (for England).

In 1535, Henry added the "supremacy phrase" to the royal style, which became "Henry the Eighth, by the Grace of God, King of England and France, Defender of the Faith, Lord of Ireland and of the Church of England in Earth Supreme Head". In 1536, the phrase "of the Church of England" changed to "of the Church of England and also of Ireland ". In 1541, Henry had the Irish Parliament change the title "Lord of Ireland" to "King of Ireland" with the Crown of Ireland Act 1542, after being advised that many Irish people regarded the Pope as the true head of their country, with the Lord acting as a mere representative. The reason the Irish regarded the Pope as their overlord was that Ireland had originally been given to King Henry II of England by Pope Adrian IV in the 12th century as a feudal territory under papal overlordship. The meeting of the Irish Parliament that proclaimed Henry VIII as King of Ireland was the first meeting attended by the Gaelic Irish chieftains as well as the Anglo-Irish aristocrats. 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 Supreme Head" remained in use until the end of Henry's reign.
