Ulvhild originated from Norway. The Norse saga manuscript Fagrskinna mentions her as the daughter of the Norwegian magnate Haakon Finnsson, of the Thjotta family. The name of her mother has not been preserved to later centuries. In modern times it has been suggested that her mother was the former Norwegian and Danish queen Margaret Fredkulla, daughter of Inge I of Sweden. However, this hypothesis cannot be substantiated.
Marriages
Young Ulvhild was firstly married to King Inge II of Sweden, in about 1116/17. They appear not to have had children. Inge was the junior of two reigning brothers. The elder brother, King Philip died in 1118 under unknown circumstances, leaving Inge as the sole ruler. The short chronicle in the Westrogothic law says that King Inge died of an evil drink in Östergötland. Some later sources place the assassination in Vreta Abbey. The year is not known, but it was no later than c. 1129. The writer Åke Ohlmarks has speculated that Ulvhild became acquainted with her future husband, the East Geatic magnate Sverker, and made him poison Inge. Some time after the death of King Inge, Ulvhild moved to Denmark, rather than returning to Norway. Perhaps she did so to claim asylum: she seems to have had relatives and allies in Denmark, whereas political turbulence plagued Sweden. She married King Niels of Denmark after the death of his first queen, Margaret Fredkulla of Sweden, in c. 1130. The marriage more or less coincided with Niels's son Magnus the Strong being accepted as king in parts of Sweden. However, Ulvhild egged her stepson Magnus against his cousin and rival Canute Lavard. Canute was eventually murdered by Magnus in 1131. Civil war now broke out in Denmark, where Niels and Magnus stood against the claimant Eric Emun. Moreover, the marriage was not harmonious, and Niels was some 20–30 years older than his spouse. The chronicler Saxo Grammaticus informs us of the dramatic dissolution: "Meanwhile the Swedes, when they heard that Magnus was busy with war in Denmark, took a fellow countryman called Sverker, a man of low origins, as their king; not since they valued him that much, but since they would not stand under a foreigner. Since they were used to having one of their own at the head, they could not accept having a foreigner as chief. Niels had married Ulvhild from Norway after Margaret's death. Sverker sent errands to her and asked for her love. Shortly afterwards he clandestinely brought her from her husband and made her marry him. With this mistress whom he falsely called his wedded wife, he sired a son Charles who became king after him." The event is not dated but must have taken place between 1132 and 1134. The curious elopement story may be explained by Ulvhild's position. Being the widow of Inge II, she represented the estates and influences of the extinct House of Stenkil. Marriage to Ulvhild legitimated the enthronement of the non-royal grandee Sverker, now when her stepson Magnus had been evicted from Sweden. As far as known, no objections were made against her third marriage or against the legitimacy of her children. On the contrary, Ulvhild is praised by clerical sources as a benefactor to the church. The Cistercians were called in on Ulvhild's initiative, and founded the abbeys of Alvastra and Nydala in 1143. Alvasta was even founded on ground which was part of Sverker's bridal gift to Ulvhild. After at least a decade of queenship, Ulvhild died, some time between 1143 and 1150. Sverker married secondly with Rikissa of Poland, widow of Magnus, king of Gothenland, Sverker's earlier rival and opponent. This, too, was a politically motivated marriage which may have aimed to draw the last remains of Magnus's party to Sverker.
Children and family
Ulvhild was married three times; to King Inge II of Sweden in c. 1117, to King Niels of Denmark in c. 1130, and to King Sverker I of Sweden in c. 1134. She had at least two surviving sons and two surviving daughters, all born of her third marriage with Sverker:
Jon Sverkersson of Sweden,, mentioned as jarl, but killed by peasants during last years of his father Sverker.
Charles VII of Sweden,, who after his father's murder held Gothenland, was possibly called jarl and certainly considered his father's heir and dynastical successor, but ultimately succeeded to the throne of Sweden after their dynasty's rivals Eric IX and Magnus II, as King Charles VII of Sweden.
Some genealogies have it that Sune Sik was a younger son of King Sverker, being the father ofIngrid Ylva; it is fully possible that he was also a son of Ulvhild.
