John Lackland, Richard's successor, refused to come to the French court for a trial against the Lusignans and, as Louis VI had done often to his rebellious vassals, Philip II confiscated John's possessions in France. John's defeat was swift and his attempts to reconquer his French possession at the decisive Battle of Bouvines (1214) resulted in complete failure. The annexation of Normandy and Anjou was confirmed, the Counts of Boulogne and Flanders were captured, and the Emperor Otto IV was overthrown by Philip's ally Frederick II. Aquitaine and Gascony survived the French conquest, for the Duchess Eleanor still lived. Philip II of France was crucial in ordering Western European politics in both England and France.
