What if, anytime between the death of Magnus the Good in 1047 and sometime after the Battle of Hastings, Sweyn II Estridsson, King of Denmark, decided to try and conquer Norway? I'm not sure if he had any claim to it, like he did with England, but when Magnus died IOTL, Harald Hadradra tried to conquer Denmark from Sweyn. And if Sweyn succeeded, what would the most likely outcome be?
Any thoughts?
