Guttorm Haraldsson was the first son of king Harald Fairhair of Norway and Åsa, daughter of Håkon Grjotgardsson. C. 890 Harald made Guttorm king of Ranrike, which he had wrested from the Swedish king Erik Eymundsson, and gave him the responsibility of defending Norway from Sweden. He fell in a sea battle against the sea-king Solve Klove.
