The Reformation and the political constitution.
In the political constitution of Germany the peace of Westphalia did not so much make changes as sanction those already effected. The whole tendency of the Reformation had been to relax the bonds which united the various elements of the state to each other and to their head. It divided the nation into two hostile parties, and the emperor was not able to assume towards them a perfectly impartial position. His imperial crown imposed upon him the necessity of associating himself with the Roman Catholics; so that the Protestants had a new and powerful reason for looking upon him with jealousy, and trying to diminish his authority. The Roman Catholics, while maintaining their religion, were willing enough to co-operate with them for this object; and Germany often saw the strange spectacle of princes rallying round the emperor for the defence of the church, and at the same time striking deadly blows at his political influence. The diet was a scene of perpetual quarrelling between the two factions, and their differences made it impossible for the imperial chamber to move beyond the region of official routine. Thus before the Thirty Years' War the Empire had virtually ceased to exist, Germany having become a loose confederation of principalities and free cities. For a moment the emperor Ferdinand appeared to have touched the ideal of Charles V. in so far, at least, as it related to Germany, but only for a moment. The stars in their courses fought against him, and at the time of his death he saw how far beyond his power were the forces with which even Charles had been unable to contend. The state of things which actually existed the peace of Westphalia made legal. So nearly complete was the independence of the states that each received the right to form alliances with any of the others, or with foreign powers, nominally on condition that their alliances should not be injurious to the emperor or to the Empire. Any authority which still lawfully belonged to the emperor was transferred to the diet. It alone had now the power of making laws, of concluding treaties in the name of Germany, and of declaring war and re-establishing peace. No one, however, expected that it would be of any real service. From 1663 it became a permanent body, and was attended only by the representatives of the princes and the cities; and from that time it occupied itself mainly with trifles, leaving the affairs of each state to be looked after by its own authorities, and those of the country generally to such fortunes as chance should determine.
