The very completeness of the humiliation of Germany was the means of her deliverance. She had been taught self-respect by Frederick II., and by her great writers in literature and philosophy; it was felt to be intolerable that in politics she should do the bidding of a foreign master. Among a large section of the community patriotism became for the first time a consuming passion, and it was stimulated by the counsels of several manly teachers, among whom the first place belongs to the philosopher Fichte. The governments cautiously took advantage of the national movement to strengthen their position. Even in Austria, where on the 8th of October 1809 Metternich had become minister for foreign affairs and the dominant influence in the councils of the empire, some timely concessions were made to the various populations. Prussia, under the guidance of her great minister Stein, reorganized her entire administration. She abolished serfdom, granted municipal rights to the cities, established an admirable system of elementary and secondary education, and invited all classes to compete for civil offices; and ample means were provided for the approaching struggle by drastic military reform. Napoleon had extracted an engagement that the Prussian army should be limited to 42,000 men. This was fulfilled in the letter, but in spirit set aside, for one body of men was trained after another until the larger part of the male population were in a position, when a fitting opportunity should occur, to take up arms for their country. War of Liberation. The disastrous retreat of the French from Moscow in 1812 gave Germany the occasion she desired. In 1813 King Frederick William, after an agony of hesitation, was forced by the patriotic initiative of General Yorck, who concluded with the Russians the convention of Tauroggen on his own responsibility, and by the pressure of public opinion supported by Queen Louise and by Hardenberg, to enter into an alliance with Russia. All now depended on the attitude of Austria; and this was for some time doubtful. The diplomacy of Metternich (q.v.), untouched by the patriotic fervour which he disliked and distrusted, was directed solely to gaining time to enable Austria to intervene with decisive effect and win for the Habsburg monarchy the position it had lost. When the time came, after the famous interview with Napoleon at Dresden, and the breakdown of the abortive congress of Prague, Austria threw in her lot with the allies. The campaign that followed, after some initial reverses, culminated in the crushing victory of the allies at Leipzig (October 16-18, 1813), and was succeeded by the joint invasion of France, during which the German troops wreaked vengeance on the unhappy population for the wrongs and violences of the French rule in Germany.
