THE SWEDISH-FRENCH PERIOD (1635-1648).—Had it not been for the selfish and ambitious interference of France, the woeful war which had now desolated Germany for half a century might here have come to an end, for both sides were weary of it and ready for negotiations of peace. But Richelieu was not willing that the war should end until the House of Austria was thoroughly crippled. Accordingly he encouraged Oxenstiern, the Swedish chancellor, to persevere in carrying on the war, promising him the aid of the French armies.

The war thus lost in large part its original character of a contest between the Catholic and the Protestant princes of Germany, and became a political struggle between the House of Austria and the House of Bourbon, in which the former was fighting for existence, the latter for national aggrandizement.

THE TREATY OF WESTPHALIA (1648).—And so the miserable war dragged on. The earlier actors in the drama at length passed from the scene, but their parts were carried on by others. The year 1643, which marks the death of Richelieu, heard the first whisperings of peace. Everybody was inexpressibly weary of the war, and longed for the cessation of its horrors, yet each one wanted peace on terms advantageous to himself. The arrangement of the articles of peace was a matter of immense difficulty; for the affairs and boundaries of the states of Central Europe were in almost hopeless confusion. After five years of memorable discussion and negotiation, the articles of the celebrated Treaty of Westphalia, as it was called, were signed by the different European powers.

The chief articles of this important treaty may be made to fall under two heads: (1) those relating to territorial boundaries, and (2) those respecting religion.

As to the first, these cut short in three directions the actual or nominal limits of the Holy Roman Empire. Switzerland and the United Netherlands were severed from it; for though both of these countries had been for a long time practically independent of the empire, this independence had never been acknowledged in any formal way. The claim of France to the three cities of Metz, Toul, and Verdun in Lorraine, which places she had held for about a century, was confirmed, and a great part of Alsace was given to her. Thus on the west, on the southwest, and on the northwest, the empire suffered loss.

Sweden was given cities and territories in Northern Germany which gave her control of a long strip of the Baltic shore, a most valuable possession. But these lands were not given to the Swedish king in full sovereignty; they still remained a part of the Germanic body, and the king of Sweden as to them became a prince of the empire.

The changes within the empire were many, and some of them important.
Brandenburg especially received considerable additions of territory.

The articles respecting religion were even more important than those which established the metes and bounds of the different states. Catholics, Lutherans, and Calvinists were all put upon the same footing. The Protestants were to retain all the benefices and Church property of which they had possession in 1624. Every prince was to have the right to make his religion the religion of his people, and to banish all who refused to adopt the established creed: but such non-conformists were to have three years in which to emigrate.

The different states of the empire were left almost independent of the emperor. They were given the right to form alliances with one another and with foreign princes; but not, of course, against the empire or emperor. This provision made Germany nothing more than a lax confederation, and postponed to a distant future the nationalization of the German states.

EFFECTS OF THE WAR UPON GERMANY.—It is simply impossible to picture the wretched condition in which the Thirty Years' War left Germany. When the struggle began, the population of the country was 30,000,000; when it ended, 12,000,000. Many of the once large and flourishing cities were reduced to "mere shells." Two or three hundred ill-clad persons constituted the population of Berlin. The duchy of Würtemburg, which had half a million of inhabitants at the commencement of the war, at its close had barely 50,000. On every hand were the charred remains of the hovels of the peasants and the palaces of the nobility. The lines of commerce were broken, and some trades and industries were swept quite out of existence.
