(d. 1329), earl of Louth. Bermingham commanded the force that defeated and killed Edward Bruce at the battle of Faughart in 1318. This exploit led Edward II to grant him the earldom and liberty of Louth in 1319. He was son of Peter de Bermingham (d.1308), who had murdered many of the O'Connors of Offaly in 1305. The earl formed a link with the king's favourite Hugh Despenser, and was justiciar of Ireland in 1321–4. He seized the Irish lands of the Despensers' enemy Roger Mortimer, and brought troops from Ireland to the Scottish campaign of 1322. After the fall of Edward II and the Despensers in 1326, his star waned. His rule was unwelcome to the gentry of Louth; in June 1329 they assassinated him and many of his followers, and rapidly obtained pardons from the Mortimer government in England.
