Conclusion
The leader of sweden during the thirty years war (image quest)
The resukt of the the Thirty Years War seems to be this; after 1648 there were no more religious wars in Europe. The disease of zealotry had been burned out in the fever of war. Much like the Peace of Augsburg, German princes were still able to select their region's religion. This is connected to modern day Europe by allowing Protestants and Catholics a chance to live peacefully together.
