The title "King of Ireland" was created by an act of the Irish Parliament in 1541, replacing the Lordship of Ireland, which had existed since 1171, with the Kingdom of Ireland. The Crown of Ireland Act 1542 established a personal union between the English and Irish crowns, providing that whoever was King of England was to be King of Ireland as well, and so its first holder was King Henry VIII of England. Henry's sixth and last wife, Katherine Parr, was the first Queen consort of Ireland following her marriage to King Henry in 1543. This followed the failure of the plan to make The 1st Duke of Richmond and Somerset (1519–1536), Henry VIII's illegitimate son, into the King of Ireland. Although Richmond was made Lord Lieutenant, the King's counsellors feared that creating a separate Kingdom of Ireland, with a ruler other than that of England, would create another threat like the King of Scotland.
