 Henry was forced to take part in the swearing of a collective oath to uphold the Provisions.Seeking to restore his position, in 1259 Henry purchased the support of King Louis IX of France by the Treaty of Paris, agreeing to accept the loss of the lands in France that had been seized from him and from his father King John by Louis and his predecessors since 1202, and to do homage for those that remained in his hands.In 1261 he obtained a papal bull releasing him from his oath, and set about reasserting his control of government.
