Valdemar was the son of Princess Ingeborg Eriksdotter of Sweden and Birger Jarl, from the House of Bjelbo. Valdemar"s mother was a daughter of King Eric X of Sweden and Princess Richeza of Denmark.
During the first sixteen years of his reign, it was Birger Jarl who was the real ruler. Birger Jarl had in fact been the de facto ruler of Sweden from 1248, before the reign of Valdemar, under King Eric XI of Sweden. When King Eric XI died in 1250, Valdemar was elected king.
Even after the coming of age of Valdemar in 1257, Birger Jarl held a grip over the country.
In 1260, Valdemar married Sofia of Denmark the eldest daughter of King Eric IV of Denmark and Jutta of Saxony. 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.
Magnus was elected King Magnus III of Sweden at the Stones of Mora.
In 1277, Sophia separated from her spouse and returned to Denmark. In 1277, 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.
