[1] Brigida Haraldsdotter was the illegitimate daughter of King Harald IV of Norway.
According to legend, she was first married to King Inge the Younger, but this is not considered possible; likely, her first marriage was to the Swedish jarl Karl Sunesson.
After his death in 1161, she remarried the Swedish jarl Birger Brosa of the Bjälbo family.
The daughter she had during her marriage to Brosa, Ingegerd Birgersdotter, was to become Queen of Sweden in 1200 as the wife of Sverker the Younger.
In 1174, the Norwegian throne claimant Øystein Møyla, who claimed to be her nephew, asked for the support of her and her husband, which they also granted.
