He was made earl of Chester in 1320 and duke of Aquitaine in 1325 and accompanied his mother to France in 1325. He returned to England with Isabella and Roger de Mortimer, 1st earl of March, on their expedition of 1326. In 1327, on his father's deposition, he was made king, although the real power was in fact exercised by Isabella and Mortimer. In 1328 he married Philippa of Hainaut, and in 1330 his first son, Edward the Black Prince, was born. In this year the king executed a coup and seized the reins of government, putting Mortimer to death and forcing his mother into retirement.
