The Revolt of 1173–1174 was a rebellion against King Henry II of England by three of his sons, his wife Eleanor of Aquitaine, and their rebel supporters. The revolt ended in failure after eighteen months; Henry's rebellious family members had to resign themselves to his continuing rule and were reconciled to him. Background King Henry II had been ruling England, Normandy, and Anjou since 1154, while his wife Queen Eleanor ruled the vast territory of Aquitaine since 1137. In 1173 Henry had four legitimate sons (from oldest to youngest): Henry, called the "Young King", Richard (later called "the Lionheart"), Geoffrey, and John ("Lackland"), all of whom stood to inherit some or all of these possessions. Henry also had an illegitimate son, Geoffrey, born probably before the eldest of the legitimate children. By this time, Henry the Young King was 18 years old and praised for his good looks and charm. He had been long-married to the daughter of Louis VII of France, the former husband of Eleanor (Henry the Young King's mother). Henry the Young King kept a large and glamorous retinue but was constrained by his lack of resources: "he had many knights but he had no means to give rewards and gifts to the knights". The young Henry was therefore anxious to take control of some of his ancestral inheritances to rule in his own right. The immediate practical cause of the rebellion was Henry II's decision to bequeath three castles, which were within the realm of the Young King's inheritance, to his youngest son, John, as part of the arrangements for John's marriage to the daughter of the Count of Maurienne. At this, Henry the Young King was encouraged to rebel by many aristocrats who saw potential profit and gain in a power transition. His mother Eleanor had been feuding with her husband, and she joined the cause as did many others upset by Henry's possible involvement in the murder of Archbishop Thomas Becket in 1170, which had left Henry alienated throughout Christendom. In March 1173 Henry the Young King withdrew to the court of his father-in-law, Louis, in France and was soon followed by his brothers Richard and Geoffrey. Eleanor tried to join them but was stopped by Henry II on the way and held in captivity. The Young King and his French mentor created a wide alliance against Henry II by promising land and revenues
