 Not content with his part , Despenser used his relationship with the king to impinge on the lands of other Marcher lords . This caused resentment among such men as Hereford and Roger Mortimer , who rose up in rebellion in 1321 . The rebellion was crushed , but resistance continued under the Marcher lords ' ally Thomas of Lancaster , who was defeated at the Battle of Boroughbridge in 1322 , and executed . Although this victory temporarily secured Edward 's position on the throne , he was eventually deposed in 1326 by Roger Mortimer , with the help of the king 's wife Queen Isabella . The title of Earl of Gloucester was recreated by Edward II 's son Edward III in 1337 , for Hugh de Audley .
