What were the political consequences of the Protestant Reformation ?
There were two major political consequences of the Protestant Reformation.
First, the Reformation helped to create major splits within the various states of Germany that were all supposed to be part of the Holy Roman Empire. The various states chose sides (based as much on politics as on faith), with some becoming Protestant and others remaining Catholic.
Second, this same sort of process happened all over Europe and helped to change European politics. Countries started, to some extent, to base their alliances on religious faith. The Reformation also led to religious wars such as the Thirty Years’ War which at least began as a religious war.
