As it says on the lid. What if the Wittelsbachs in Bavaria had decided with the Reformation to join the other major German princes in going over to the dark side...I mean the Protestant church? What effects might this have on German politics as a whole? And to which brand of the Protestant faith is Bavaria more likely to move? Calvinism held a sort of sway over the west of Germany, Lutheranism over the east, but this isn't a hard and fast rule - Brandenburg was Calvinist and Hannover/Brunswick was Lutheran. Plus their Palatine cousins went Calvinist, but there was animosity between the two branches (or was that only after the 30YW?).
