ブーヴィーヌの戦い
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. Philip II had annexed Normandy and Anjou, plus capturing the Counts of Boulogne and Flanders, although Aquitaine and Gascony remained loyal to the Plantagenet King. In an additional aftermath of the Battle of Bouvines, John's ally Holy Roman Emperor Otto IV was overthrown by Frederick II, member of the House of Hohenstaufen and ally of Philip. Philip II of France was crucial in ordering Western European politics in both England and France.
