Valdemar's father was Duke Eric II of Schleswig and mother was Adelheid of Holstein, 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, the 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. Due to his young age, his maternal uncle, the mighty Count Gerhard of Rendsborg (Gerhard III of Holstein) who also was the biggest pawnholder of mortgaged Denmark, was appointed as the Regent and guardian ("grev Gert eller Den kullede Greve").

Valdemar's ascension promissory was at least as strict as Christopher's had been. There were some new stipulations, such as all royal castles in Scania should be demolished, and all nobles received the right to fortify their home steads. The most important agreement however was so-called Constitutio Valdemariana that promised that in all future, never the same person could be both ruler of Slesvig and Denmark simultaneously.

Valdemar accordingly gave up his patrimony, Schleswig, and entfeoffed it to his uncle and guardian, whereby the first Holsteiner became a Duke: Gerhard, Duke of Jutland (or Sonderjylland or Schleswig).

Denmark was now held totally by certain nobles, in practice. That was not popular among peasants. Portion of them were foreigners, and many set up new taxes. In 1328, peasants in Zeeland rose to rebellion, which though was quelled. In 1329, was Jutland's turn to rebel. They had a better success, but were also quelled in the end. Finally, count Gerhard gave up in the name of his king, and in 1329 Christopher II was allowed to return to the throne. Valdemar became again Duke of Schleswig.

In 1340, he gave his only sister Helvig of Schleswig to marriage with Valdemar IV, the new king of Denmark.

Valdemar died in 1364. He was married to Richardis of Lauenburg. They had two sons, Henry (died 1375) and Valdemar (died 1364), elder of whom, Henry, succeeded in Schleswig upon Valdemar's death. This article discusses the Lauenburg in Schleswig-Holstein. ...
