Cine s-a căsătorit cu Niels, King of Denmark?

Niels (c. 1065 – 25 June 1134) was the King of Denmark from 1104 to 1134. Niels succeeded his brother Eric Evergood and is presumed to have been the youngest son of King Sweyn II Estridson. King Niels actively supported the canonization of Canute IV the Holy and supported his son Magnus after he killed his rival for the succession, Knud Lavard. His secular rule was supported by the clergy. Niels was killed in an ensuing civil war and succeeded by Eric II Emune.

Ulvhild Håkansdotter (Swedish: Ulfhild; c. 1095 – c. 1148) was twice Queen of Sweden (c. 1117–25 and c. 1134–48) and once Queen of Denmark (c. 1130–34) through her successive marriages to Inge II of Sweden, Niels of Denmark, and Sverker I of Sweden. Ulvhild had an important role in the Nordic dynastic connections of her time, but the sources are insufficient on detailed circumstances. She is mentioned as a femme fatale of medieval Scandinavia, as well as a benefactor of the Catholic Church.
