"Valdemar Knudsen (also Waldemar, born in 1158; died 18 July 1236 in Cîteaux) was a Danish clergyman and statesman. Valdemar was Bishop of Schleswig from 1188 to 1208, officiated as Steward of the Duchy of Schleswig between 1184 and 1187, and served as Prince-Archbishop of Bremen from 1192 to 1194 and again between 1206 and 1217. He held the latter office on the grounds of the archdiocesan capitular election as archbishop elect and of the royal investiture with the princely regalia, but lacked the papal confirmation.
His mother, likely the wife of another man, gave birth to him as the posthumous illegitimate son of King Canute V of Denmark in early 1158. His father Canute V had been slain on 9 August 1157 by the co-regent Sweyn III. So Valdemar, like his half-brother, Saint Niels of Århus, claimed succession to the Danish throne." - (en.wikipedia.org 12.08.2020)
