Baron Inchiquin

Baron Inchiquin (Irish: Barún Inse Uí Chuinn) is one of the older titles in the Peerage of Ireland. It was one of two titles created on 1 July 1543 for Murrough O'Brien, Prince of Thomond, who claimed descent from Brian Boru, a High King of Ireland. The English titles were granted under the policy of surrender and regrant, and therefore conditional upon the abandonment of any Irish titles, the adoption of English customs and laws, pledging of allegiance to the Crown, apostasy from the Catholic Church, and conversion to the Church of Ireland. Murrough was made both Earl of Thomond in the Peerage of Ireland, with remainder to his nephew Donough O'Brien and Baron Inchiquin, with remainder to his male heirs. Following the death of his first cousin, Conor O'Brien, 18th Baron Inchiquin, in June 2023, he was succeeded by Conor O'Brien, 19th Baron Inchiquin.
