Baron Inchiquin 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 was descended from the great high king Brian Boru. The grant of the English titles was 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 England. 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.
Sir Murrough O'Brien, 10th Baron of Inchiquin, 5th Baron O'Brien of Burren, 1st Baron Thomond of Taplow, 5th Earl of Inchiquin, 1st Marquess of Thomond KP, PC (Ire), known from 1777 to 1800 as the 5th Earl of Inchiquin, was an Irish peer, soldier and politician.
During the Tudor conquest of Ireland (c.1540–1603), "surrender and regrant" was the legal mechanism by which Irish clans were to be converted from a power structure rooted in clan and kin loyalties, to a late-feudal system under the English legal system. The policy was an attempt to incorporate the clan chiefs into the English-controlled Kingdom of Ireland, and to guarantee their property under English common law, as distinct from the traditional Irish Brehon law system. This strategy was the primary non-violent method for Crown officials in the Dublin Castle administration to subjugate Irish clan leaders during the conquest. It was an unanticipated consequence to be required to pay fealty in currency instead of trade labor or commodities. The process of "surrender and regrant" thus created new, unfamiliar debt structures among the Irish, and these debts had social and political consequences.
