Henry the Young King of England (b. 1155)

Henry the Young King (28 February 1155 – 11 June 1183) was the eldest surviving son of Henry II of England and Eleanor of Aquitaine. Beginning in 1170, he was 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 was frustrated by his father's refusal to grant him meaningful autonomous power. He died aged 28, six years before his father, leaving his brother Richard to become the next king.
