Olof Skötkonung, (Old Norse:Óláfr skautkonungr) sometimes stylized asOlaf the Swede (c. 980–1022), was King of Sweden, son ofEric the Victorious and, according to Icelandic sources,Sigrid the Haughty. He succeeded his father in c. 995. He stands at the threshold of recorded history, since he is the first Swedish ruler about whom there is substantial knowledge. He is regarded as the first king known to have ruled both theSwedes and theGeats. In Sweden, the reign of king Olov Skötkonung is considered to be the transition from the Viking age to the Middle Ages, because he was the first Christian king of theSwedes, who were the last to adopt Christianity inScandinavia. He is associated with a growing influence of the church in what is today southwestern and central Sweden. Norse beliefs persisted in parts ofSweden until the 12th century.

Olof was victorious alongsideSweyn Forkbeard when the kings created an alliance to defeat the Norwegian kingOlaf Tryggvason in theBattle of Svolder. After the battle, the victorious leaders split Norway into areas of control.Heimskringla gives the most detailed account of the division. Olof received four districts in Trondheim as well as Møre, Romsdal and Rånrike.
