When Edward II left the country early in 1308 to marry the French king's daughter Isabella, he appointed Gaveston regent in his place. This was a responsibility that would normally be given to a close family member of the reigning king. There is no sign that Gaveston exploited the regency for personal gains, but the other nobles were still offended by his arrogant behaviour. This behaviour continued at the coronation feast after the King's return, during which the King largely ignored his new wife in favour of Gaveston. The collective grievances first found expression in the so-called 'Boulogne agreement' of January 1308, in which the earls of Warenne, Hereford, Lincoln and Pembroke expressed concern about oppression of the people and attacks on the honour of the crown. Though not mentioned by name, Gaveston was the implied target of this document. Later that year, in the April parliament, the so-called Declaration of 1308 demanded the renewed exile of Gaveston, again without explicitly mentioning the favourite by name. The King initially resisted, but had to give in to the demand once it became clear that the barons had the support of King Philip IV of France, who was offended by Edward's treatment of his daughter. On 18 May, Edward consented to sending Gaveston into exile.
