Ragnvald Ulfsson

Ragnvald Ulfsson the Old (beginning 11th century) was a jarl of Västergötland or Östergötland, and married to a sister of Olav Tryggvason.

Ragnvald is mentioned in the skaldic poem Austrfaravísur, ascribed to Sigvatr Þórðarson, skald of King Olaf Haraldsson of Norway (Olaf the Holy), who had been on a diplomatic mission to Sweden. This poem is quoted in the 13th century sagas Fagrskinna and Snorri Sturluson's Heimskringla. In addition to the poem, Fagrskinna only briefly mentions Ragnvald, while Heimskringla contains a more elaborate account of him. This 13th-century prose text is not considered historically reliable.

According to Snorri, Ragnvald was the son of jarl Ulf Tostesson and Ingeborg and the foster-son of Þorgnýr the Lawspeaker. He was the cousin of Olof Skötkonung, through his aunt Sigrid the Haughty, and he was married to Ingeborg Tryggvasdotter.

During his days the Norwegians pillaged in Västergötland, but then the Norwegian king, Olaf the Holy, proposed to the Swedish princess Ingigerd Olofsdotter, the daughter of Sweden's king Olof Skötkonung. This pleased Ragnvald who was related to both.
