Valdemar the Young

Valdemar the Young (c. 1209–1231) was the only child of King Valdemar II of Denmark and his first queen, Dagmar of Bohemia. In 1215 he was made co-king beside his father, entrenching the new hereditary kingship, though he never reigned alone.

In 1223 he was seized together with his father by Count Henry of Schwerin during the hunt on Lyø and shared his captivity. On 28 November 1231 he was accidentally killed by an arrow while hunting at Refsnæs, dying before his father.
