Meanwhile, the Earl of Pembroke had been negotiating with France to resolve the long-standing disagreements over the administration of Gascony, and as part of this Edward and Isabella agreed to travel to Paris in June 1313 to meet with Philip IV. Edward probably hoped both to resolve the problems in the south of France and to win Philip's support in the dispute with the barons; for Philip it was an opportunity to impress his son-in-law with his power and wealth. It proved a spectacular visit, including a grand ceremony in which the two kings knighted Philip's sons and 200 other men in Notre-Dame de Paris, large banquets along the River Seine, and a public declaration that both kings and their queens would join a crusade to the Levant. Philip gave lenient terms for settling the problems in Gascony, and the event was spoiled only by a serious fire in Edward's quarters.
