The antagonism between these conflicting principles was not long in revealing itself. In Germany the relations between Austria and Prussia were becoming unpleasantly strained in the question of the admission of the Habsburg monarchy to the Zollverein, in that of the elector of Hesse and his parliament, in that of the relation of the Elbe duchies to the crown of Denmark. But for the outbreak of the Italian war of 1859 the struggle of 1866 might have been anticipated. The outcome of the war increased the prestige of Prussia. She had armed, not with the idea of going to the aid of a German power in difficulties, but in order, at the right moment, to cast her sword into the scale wherein her own interests might for the time lie. At the menace of her armaments, concentrated on the Rhine, Napoleon had stopped dead in the full career of victory; Austria, in the eyes of German men, had been placed under an obligation to her rival; and Italy realized the emergence of a new military power, whose interests in antagonism to Austria were identical with her own.
Military reforms and constitutional crisis in Prussia.
So striking an object lesson was not lost on the Prussian regent, and he entered on a vigorous policy of reforming and strengthening the army, General von Roon being appointed minister of war for this purpose. To the Liberal ministers, however, and to the Liberal majority in the Prussian diet, this was wholly objectionable. Schemes were under discussion for reforming the constitution of the Confederation and drawing the German states closer together on a Liberal basis; the moment seemed singularly inopportune for Prussia, which had not shown herself particularly zealous for the common interests, to menace the other German governments by increasing her separate armaments. When, therefore, on the 10th of February 1860, the bills necessary for carrying out the reform of the army were introduced into the diet, they met with so strenuous an opposition that they had to be withdrawn. Supplies were, however, granted for fourteen months, and the regent took this as justifying him in proceeding with his plans. On the 1st of January 1861 the standards of the new regiments were solemnly blessed; on the next day Frederick William IV. died, and the new king was face to face with a constitutional crisis.
