What are the odds, or better said, was it even possible, provided there was a political will and backing, to structure Norse paganism into a proper religion capable of resisting the advance of Christianity into Scandinavia? Ideally around the time of Charlemagne and Irminsul burning.
Secondly, provided paganism was still active in Scandinavia, would Crusades even happen as they did OTL? Would Pope see it paramount to secure Europe first from heathen raiders and thus organise Northern Crusades?
Would existance of Pagans there affect survival of pagans in Lithuania and/or other places?
And lastly, would Northern Europe start being and stay being seen as other, different and alien, comparable to Russia, or Turkey, from perspective of Western European/ concept of "European"
