The long reign of Frederick William III. is the richest period of Prussia's history. Here begins that development whose progress is now one of the most noteworthy of our time. The king, cautious, conscientious, patriotic, but timid, declined to join the Second Coalition (1799), hoping thereby to secure Prussia against the ravages of war. Prominent Prussians, moreover, were positively friendly to Napoleon; so that, even after the latter had violated his obligations by marching through Prussian territory, the king hesitated a year to declare war. This was done August 9, 1806; but two months later his army was routed at Jena; Napoleon entered Berlin; the Prussians were finally defeated at Friedland by the French, and at Tilsit, July 9, 1807, the Prussian king was forced to give up the half of his domains, and to furnish the conqueror a tribute of one hundred and forty millions of francs. For six years Prussia lay prostrate at the feet of France. In 1812 he was compelled to furnish twenty thousand men to join Napoleon's army in his invasion of Russia. Not till after the disastrous issue of this invasion did king or people dare to lift an arm in defence of the national independence. But these years compose just the period which Prussians love to call that of Prussia's regeneration. The insolence of the conqueror united the national heart. Full of the most flaming patriotism, and not doubting that deliverance would finally come, statesmen and warriors, Stein, Scharnhorst, Bluecher, Schill, and others, labored unweariedly to keep up the spirits of the people, and prepare them for the coming War of Liberation. Now for the first time the cities were invested with the right to regulate their own internal affairs. Now for the first time the peasants were delivered from the serfdom under which they had hitherto suffered. In short, the whole policy of the Government was determined by the resolution to inspire the people with a healthful, unconstrained, enthusiastic devotion to the national weal, and, as a means to this end, with zeal for the king. These efforts were fully successful. When the providential time arrived, and the king issued, February 3, 1813, a call for volunteers, and, March 17, his famous _Aufruf an mein Volk_, all Prussia sprang to arms. In alliance with Russia, finally also assisted by Austria and Sweden, her troops were engaged in nine bloody battles with the French between April 5 and October 18, the enthusiasm of the people and the dogged intrepidity of Bluecher being at length rewarded by the decisive victory at Leipsic. The immediate result of this victory for Prussia was the recovery of the territory between the Elbe and the Rhine ceded to France by the preceding king. At the congress of Vienna there were assigned to her in addition all that she had possessed before the Treaty of Tilsit, half of Saxony, and an increase of the former possessions on the Rhine. Some further acquisitions and cessions were made at the second Treaty of
