Valdemar, King of Sweden
Valdemar (English: Waldemar; ; 1239 – 26 December 1302) was King of Sweden from 1250 to 1275.

Biography
Valdemar was the son of the Swedish princess Ingeborg Eriksdotter and Birger Jarl, from the House of Bjelbo. When her brother King Eric XI died in 1250, though a child, Valdemar was elected king and crowned the following year in the cathedral at Linköping. During the first sixteen years of his reign, it was Birger Jarl who was the real ruler. Birger Jarl had been the de facto ruler of Sweden from 1248, before the reign of Valdemar, even under Eric XI. Valdemar's mother and King Eric were children of King Eric X and Richeza of Denmark.

After Birger's death in 1266 Valdemar eventually came into conflict with his younger brother Magnus Birgersson, Duke of Södermanland, over taxation and personal matters.

In 1260, Valdemar married Sophia, the eldest daughter of King Eric IV of Denmark and Jutta of Saxony. Valdemar also had a relationship with his sister-in-law Jutta.  In 1272, Jutta visited Sweden and became Valdemar's mistress. The affair resulted in a child born in 1273. The following year, Jutta was placed in a convent and Valdemar was forced to make a pilgrimage to Rome to ask for the  absolution of the Pope.

Valdemar was deposed by his brother, Magnus after the Battle of Hova in Tiveden June 14, 1275. Magnus was supported by his brother, Eric Birgersson, Duke of Småland, and King Eric V of Denmark, who provided Danish soldiers. Magnus was elected King Magnus III of Sweden at the Stones of Mora.

In 1277, Sophia separated from her spouse and returned to Denmark and Valdemar managed to regain provinces in Gothenland in the southern part of the kingdom and was called the Duke of Götaland. However, Magnus regained them about 1278. In 1288 Valdemar was imprisoned by King Magnus in Nyköping Castle (Nyköpingshus) and lived openly with mistresses, possibly new wives, in comfortable confinement.

Valdemar married Sofia of Denmark (died 1286) in 1260 and they separated in 1277. They had six children:
