Henry the Young King (28 February 1155 – 11 June 1183) was the eldest son of Henry II of England and Eleanor of Aquitaine to survive childhood. In 1170, he became titular King of England, Duke of Normandy, Count of Anjou and Maine. Henry the Young King was the only English king since the Norman Conquest to be crowned during his father's reign, but he was frustrated by his father's refusal to grant him meaningful autonomous power. He died aged 28, six years before his father, which left his brother Richard to become the next king. Early life Little is known of the young Henry before the events associated with his marriage and coronation. His mother's children by her first marriage to Louis VII of France were Marie and Alix. He had one elder brother, William (d. 1156), and his younger siblings included Matilda, Richard, Geoffrey, Eleanor, Joan and John. In June 1170, the fifteen-year-old Henry was crowned king during his father's lifetime, a traditional practice of the French Capetian dynasty which held formal overlordship of Henry II's continental domains. King Stephen had previously attempted to have his son Eustace crowned as early as 1143 but was unable to secure papal support. On the latter's death in 1153, Stephen did not even attempt to have his second son William acknowledged as heir.
