Sigurd II
king of Norway
Sigurd Haraldsson (Old Norse: Sigurðr Haraldsson; 1133 – 10 June 1155), or Sigurd II, also called Sigurd Munn, was king of Norway from 1136 to 1155. He was son of Harald IV Gille, king of Norway and his mistress Thora Guttormsdotter (Þóra Guthormsdóttir). He served as co-ruler with his half-brothers, Inge Haraldsson and Eystein II Haraldsson. His epithet Munn means "the Mouth" in Old Norse. He was killed in the power-struggle against his brother, Inge, in an early stage of the civil war era in Norway.
Reign
Sigurd was fostered by Guttorm (Guthormr) or Sådegyrd Bårdsson (Sáðagyrðr Bárðarson) in Trøndelag. When his father was murdered by the pretender Sigurd Slembe in 1136, Sigurd was made king at the thing of Eyrathing. At the same time, his brothers Inge and Magnus were also made kings and co-rulers. Their respective guardians joined forces against Sigurd Slembe and his ally, the former king Magnus the Blind. The battles against these pretenders dominated the early years of Sigurd's reign.

“Sigurd II” is worth following because a concise public description often conceals a longer documentary argument. Here, Sigurd, king and Norway provides the most credible route into that argument.
Chronology provides the most reliable spine for this subject; interpretation should follow only after identities and dates are secure. The source revision retrieved here is dated Jun 20, 2026. The linked authority identifier is Q350498. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1133, 1155 and 1136.
Later biographies can compress uncertainty and repeat inherited reputations, so apparently settled claims may still require comparison. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
