In 1325 Edward convinced Isabella to go to France. Her brother Charles IV of France was now king. Edward wanted her to negotiate for him over Gascony. This was Isabella's chance for freedom. She even convinced her husband to send their son Edward (III) to join her. Edward soon realized his mistake and demanded she and his son return. Isabella ignored his demands and remained in France. The anger she must have felt over the years of mistreatment in England finally gave her a chance to rebel against her husband. She had their son, the future king of England with her and Edward could do nothing. At this time she was joined by Roger Mortimer an English exile. Another who came to her aid was Edmund of Woodstock, 1st Earl of Kent, Edward II's half-brother. A number of Englishmen in France joined her cause. Many were upset with Edward II and the Despensers.
