 Philip recognised John as King of England, heir to his brother Richard I, and thus formally abandoned his prior support for Arthur I, Duke of Brittany, the son of John's late brother, Geoffrey II of Brittany.John, meanwhile, formally recognised the new status of the lost Norman territories by acknowledging the Counts of Boulogne and Flanders as vassals of the kings of France, not those of England, and recognised Philip as the suzerain of the continental lands in the Angevin Empire.John also bound himself not to support any rebellions on the part of the counts of Boulogne and Flanders.
