The Thirty Years' War settled once for all the principle that men should not be persecuted for their religious faith. It is true that the peace of Westphalia formally recognized only the three creeds, Catholicism, Lutheranism and Calvinism, but so much suffering had been caused by the interference of the state with individual conviction, that toleration in the largest sense, so far as law was concerned, was virtually conceded. This was the sole advantage gained from the war by the Protestants. The Catholics insisted at first on keeping all the ecclesiastical lands which had been taken from them before the Edict of Restitution in 1629. The Protestants responded by demanding that they should lose nothing which they had held before 1618, when the war began. A compromise was at last effected by both parties agreeing to the date 1624, an arrangement which secured to the Catholics their gains in Bohemia and the other territories of the house of Habsburg. The restoration of the elector palatine to part of his lands, and his reinstatement in the electoral office, were important concessions; but on the other hand, the duke of Bavaria kept the Upper Palatinate, the elector palatine becoming the eighth and junior member of the electoral college. Loss of territory. The country suffered enormous territorial losses by the war. Up to this time the possession of Metz, Toul and Verdun by France had never been officially recognized; now these bishoprics were formally conceded to her. She also received as much of Alsace as belonged to Austria. To the Swedes were granted Western Pomerania, with Stettin, and the archbishopric of Bremen and the bishopric of Verden. These acquisitions, which surpassed the advantages Gustavus Adolphus had hoped to win, gave Sweden the command both of the Baltic and of the North Sea. In virtue of her German possessions Sweden became a member of the Empire; but France obtained absolute control of her new territories. There was a further diminution of Germany by the recognition of the independence of Switzerland and the United Provinces. Both had long been virtually free; they now for the first time took the position of distinct nations. The Reformation and the political constitution.
