Wonderful to see this go forward!
Mind you-there are people who say that just looking at a map of the Holy Roman Empire makes their eyes hurt. I just kind of go blurry on it. It's trying to follow the soap opera of the various dynasties that makes my head hurt!
About the only thing that grounded me was that this time period is roughly the same one in the Grantville ISOT novels of Flint et al, so the characters aren't entirely unfamiliar to me.
It is beyond me at the moment to guess at the shaping up of the great nation-states that will presumably precipitate out of this dynastic morass. Especially bearing in mind, the two big Aurian plagues have done their terrible work--at least the first wave of it--in Europe. But soon the Aurian crops will start infiltrating. We've seen crops that can revolutionize both the north and the south of Europe. Meanwhile Sweden seems set up to be a big power on a nationalistic basis.
How exactly will the Swedes guarantee their ongoing access to their American colony in OTL-Maine? And by the way, why is Bangor, which is some distance inland, the location of the major Swedish town there and not somewhere on the coast, presumably near or at OTL-Portland? Getting back to the access question, can't the Danes try to cut them off from any access to the Atlantic at all? Will the Danes generally find it imprudent to thus alienate their neighbor-rival, will they get co-opted into some alt-Kalmar union, will the Swedes conquer them outright, or what?
The Stuarts continue to reign in Britain, correct?
Anyway IIRC a number of Aururian crops would do surprisingly well in the near-Arctic latitudes of the Baltic. So if the Swedes can avoid collapsing for a while the demographic basis of the Swedish kingdom/nation should consolidate. As would the Danes to be sure! And the Russians. OTOH Norway might get feisty, drawing the center of gravity of the Danish kingdom north or at least counterbalancing the effect of Denmark's acquisitions in former northern Germany. Or perhaps the Swedes court insurrection there whenever the Danes get too obnoxious about the straits, and this is how a sort of balance of terror leading to an amicable modus viviendi between the two Scandinavian realms evolves?
Now turning down to the Med, Spain looks pretty wasted at the moment, but the main suite of Aururean crops seems likely to revitalize Iberia eventually. Italy too should prosper in the sense of there being more Italians, better fed, though they might still be engaged in political fratricide on a grander scale. But it's been foretold, Sicily is an island to watch.
I'm not an unfan of the Ottomans, but hardly an expert, so I'll let others speculate on what the nadir of the plague and the boost of the new crops will mean south of the Med and its northeast shores from the Balkans east--though presumably the Wittelsbachs, having got a toehold on the Med, will mix into that mess. Unless they are too distracted by Empire politics and Italian politics!
I foresee a considerably more balanced development of Europe on the technical and economic fronts, instead of it being nearly as centered in northwest Atlantic coast Europe as OTL. This is partially because I don't foresee the Stuart-descended British kingdom(s?) being quite so cutting-edge--still innovative on these fronts, but blunted--whereas perhaps Sweden will be more dynamic than OTL in the 18th century which in turn might provoke/enable a somewhat more modern (if on "absolutist" lines!) Poland and Russia. Meanwhile the western Med--Iberia and Sicily but possibly also southern France and the other Med islands--will have a bit of a second Renaissance, a true "rebirth."
So capitalism in particular will probably arise more slowly and more fitfully and more gradually, but on a dispersed basis with strong centers scattered all around Europe's peripheries; parts of the Ottoman realm may participate on a pretty equal basis as well.
Hence I guess the more quilted nature of European colonialism in North America.
Again my head hurts when I try to envision what happens in the center of Europe.
