The terms of peace, called the Peace of Westphalia (1648), reflect the passing of an age. Calvinism joined Lutheranism and Catholicism as a recognized expression of the Christian faith. Princes, if they chose, could, for the first time, allow Protestants and Catholics to coexist within their territories. And the pope was excluded from any interference in the religious affairs of Germany. Naturally Pope Innocent X condemned the treaty, but both Catholics and Protestants ignored his protests.
