But the summary of Metternich's difficulties in Germany is not yet complete. The ruler of another small principality, the Duke of Weimar, had taken advantage, like the King of Würtemberg, of the permission to grant a Constitution to his people; and had been more prominent than even the King of Würtemberg in encouraging freedom of discussion in his dominions. This love of freedom, in Weimar as in most countries of Europe, connected itself with University life, and thus found its centre in the celebrated University of Jena; and on June 18th, 1816, the students of the University met to celebrate the anniversary of the Battle of Leipzig. There, to the great alarm of the authorities, they publicly burnt the pamphlet of Schmalz, and another written by the play-writer Kotzebue, who was believed to have turned away Alexander of Russia from the cause of liberty, and now to be acting as his tool and spy. The head of the Rhine police, conscious, no doubt, of the ferment in his own province, remonstrated with the Duke of Weimar on permitting such disturbances. This opposition increased the movement which it was designed to check. Jahn, who had founded the gymnastic schools which had speedily become places of military exercise for patriotic Germans during the war, now came forward to organize a Burschenschaft, a society which was to include all the patriotic students of Germany. Metternich and his friends had become thoroughly alarmed at the progress of the opposition, but again events seemed to work for him; and the enthusiasm of the students, ill-regulated, and ill-guided, was soon to give an excuse for the blow which would secure the victory for a time to the champions of absolutism. The desire for liberty seems always to connect itself with love of symbolism; and the movement for reform, naturally led to the revival of sympathy with earlier reformers. Actuated by these feelings, the students of Leipzig and other German Universities gathered at the Wartburg, in 1817, to revive the memory of Luther's testimony for liberty of thought; and they seized the opportunity for protesting against the tyranny of their own time. Apparently the enthusiasm for the Emperor of Austria had not extended to Saxony; for an Austrian corporal's staff was one of the first objects cast into the bonfire, which was lighted by the students; while the dislike to Prussia was symbolized by the burning of a pair of Prussian military stays, and the hatred of the tyranny which prevailed in the smaller States, found vent in the burning of a Hessian pig-tail. The demonstration excited much disapproval among the stricter followers of Metternich; but Stein and others protested against any attempt to hinder the students in their meeting.
