Valdemar III (1314–1364) was a
king of Denmark from 1326 to 1329 briefly when underage, as well as in 1325–26 and from 1330 to 1364 Duke of
Schleswig as
Valdemar V. He was a rival king set up against the unsuccessful
Christopher II and was widely opposed by his many subjects. His term was ended when he abdicated. Sometimes the earlier king
Valdemar the Young is called Valdemar III instead.
