Hi! I am not a historian, but I am studying history in Norway and writing a bachelor degree in Norwegian middel ages. When Harald Hardraade, left for England he had his son Olav with him. Olav was not present at the battle, so he survived and went back home to Norway. He co-ruled with his Brother Magnus, the first years before Magnus died, and Olav ruled alone. Olav got the name Olav ''Kyrre'' Meaning peacefull. The 26 years he ruled as Norwegian king, Norway was in no conflicts with other kingdoms. So the repercussion for Norways part, was that they got a king who ruled peacefully for 26 years, unlike his son but that is another story.
