In May 1200, Philip signed the Treaty of Le Goulet with Richard's successor John Lackland. The treaty was meant to bring peace to Normandy by settling the issue of its much-reduced boundaries. The terms of John's vassalage were not only for Normandy, but also for Anjou, Maine, and Touraine. John agreed to heavy terms, including the abandonment of all the English possessions in Berry and 20,000 marks of silver, while Philip in turn recognised John as king of England, formally abandoning Arthur of Brittany's candidacy, whom he had hitherto supported, recognising instead John's suzerainty over the Duchy of Brittany. To seal the treaty, a marriage between Blanche of Castile, John's niece, and Louis the Lion, Philip's son, was contracted.
