Research Notes

This temporary page is for William Mortensen Vaughan and others to submit data for Valdemar II without being Pre-1500 qualified.


A.k.a. Valdemar II, a.k.a. Valdemar II, King of Denmark


Valdemar is his given name. He is son of Valdemar I the Great. His LNAB should be Valdemarsen or Valdemarsøn in modern day Danish; Valdemarsson is Swedish.

He is also know as:

Valdemar II, King of Denmark
Valdemar Sejr (sejr meaning victorious)
Valdemar "the Victorious" [1]

"Sejr" isn't a nickname or middle name, but what is known as a byname. It would not have been used in Valdemars own time, it is a later addition to his name (probably in the 1500's).
