アイルランド卿
Following the deaths of John's older brothers he became King of England in 1199, and so the Lordship of Ireland, instead of being a separate country ruled by a junior Norman prince, came under the direct rule of the Angevin crown. In the legal terminology of John's successors, the "lordship of Ireland" referred to the sovereignty vested in the Crown of England; the corresponding territory was referred to as the "land of Ireland".
