Marriage of Henry II and Eleanor of Aquitaine

Two months after Eleanor's annulment from Louis VII of France, she married Henry, Duke of Normandy and Count of Anjou, in Poitiers on 18 May 1152. The match brought her vast duchy under Henry's control and, when he became king of England two years later, created the Angevin Empire — a French king's vassal who now controlled more of France than the king himself.
