Valdemar III of Denmark
[1] Valdemar's father was Duke Eric II of Schleswig and his mother was Adelaide, daughter of Henry I of Rendsborg.When his distant kinsman and the head of the rival royal branch Christopher II of Denmark was exiled from his kingdom, Holsteiner and Danish high nobles got to choose a new king.Their choice fell to 11-year-old Duke Valdemar V of Schleswig, who was the head of the branch descended from King Abel of Denmark.The most important agreement, however, was the so-called Constitutio Valdemariana, which promised that in the future, the same person could never be both ruler of Slesvig and Denmark simultaneously.Finally, count Gerhard gave up in the name of his king, and in 1329 Christopher II was allowed to return to the throne.
