Let's say that England remains Catholic, with one of the usual PODs (Henry and Catherine having a son, Queen Mary having a child, etc.). Without the English government supporting the Protestant cause north of the border, Scotland remains Catholic too. Let's say that the Scandinavian countries likewise stay Catholic (although I don't know enough about Scandinavian history to name a good POD). For the rest, Protestantism spreads like it did IOTL -- so the Netherlands, parts of north Germany, and some parts of Switzerland become Protestant countries; outside these areas, you get some Protestant populations (such as the Huguenots in France), but the countries as a whole remain Catholic.
What would happen as a result of this? Would the Protestant states be able to maintain their faith, or would they be compelled to return to the Catholic fold at some point? Would they still get support from outside powers (the Dutch from England, the Germans from Sweden and France)? Also, how would historiography regard the Reformation? Would it still be regarded as a turning point in European history which shattered the unity of Western Christendom, or would it be treated as more of a footnote in history, like the Cathar and Waldensian sects IOTL?
