An Irish Nationalist, trained at Dublin and Oxford Universities; entering the Irish Parliament, he by his fervid oratory soon won a place in the front rank of Irish politicians; in 1769 he was put on trial for killing an opponent in a duel, but was acquitted; from 1775 to 1781 he was Vice-Treasurer of Ireland; to Grattan's Irish Bill of Right he offered bitter opposition, holding it to be an altogether inadequate measure; in 1783 he was returned to the English House of Commons, but failed to make his mark (1732-1791).
