(1778-1803), an Irish patriot. He was expelled from Trinity College, Dublin, in 1798, on the ground of exciting disaffection and rebellion, and he then quitted Ireland. After spending some time on the Continent and receiving from Napoleon a promise of aid in a struggle for Irish independence, he returned to Ireland and became a member of the Society of United Irishmen, for the establishment of the independence of Ireland. In July, 1803, he was the ringleader in the rebellion in which Lord Kilwarden and others perished. He was arrested a few days afterward, tried and executed. His speeches in his own vindication have been regarded as models of patriotic eloquence.
