Woz Early said:The Danes siezed land by strength of arms, pillaged a lot of it and only settled after a peace treaty with a saxon king who granted a vast tract of the north to the Danes. On a fairly regular basis, the saxons resisted their danish overlords and it was clear that Denmark would have to be prepared for regular warfare if it wanted to hold onto the Danegeld. They weren't, they didn't.
The danes took the english throne partly by force partly by marring into the english dynasty and even (king Canute) moved the administrative center to England. It was however quickly lost when later kings moved the center back to Denmark.
So in this aspect the events are well enough I think.
If we are to model the norman-saxon antagonies culture (and maybe religion) should be a trait with inherent penalties (and bonuses) for (un)equal vassal and liege culture. That however might be a good idea (and as such is probably CK2 - funny how all good ideas are CK2 stuff)
