(d. 1242), 1st earl of Ulster. Hugh was in Ireland from 1195 and involved himself in the politics of Connacht. King John used him to destroy his former ally John de Courcy and in 1205 made him earl of Ulster. John became suspicious of Hugh and his brother Walter and in 1210 chased them from Ireland into Scotland. They travelled to France where Hugh participated in the Albigensian crusade until 1219. In 1220 he joined Llywelyn ap Iorwerth of Gwynedd in attacking William Marshal II in Wales. He invaded Ireland late in 1223 and plundered his enemies in Meath. The following summer the justiciar, William Marshal II, captured Trim Castle from adherents of Hugh and forced him to abandon the siege of Carrickfergus. After destroying the castle of Coleraine and harrying lands around Dundalk, Hugh surrendered to Marshal in October 1224. In April 1227 Ulster was restored to him as earl. In 1228 he was summoned by the king to fight in France and in 1234 he participated in the murder of Richard Marshal on the Curragh. In 1235 he was involved in the conquest of Connacht by Richard de Burgh. His reward was the revival of the grant made to him almost 40 years earlier by Richard's father, William. He received lands in Sligo, but apart from founding the manor of Meelick did not involve himself in Connacht, preferring to grant most of his interests to other English lords.
