The working out of the plan.
Bismarck's first step was to invite Austria to coöperate with Prussia in settling the Schleswig-Holstein difficulty. As Denmark refused to make any concessions, the two powers declared war, defeated the Danish army, and forced the king of Denmark to cede Schleswig-Holstein to the rulers of Prussia and Austria jointly (October, 1864). They were to make such disposition of the provinces as they saw fit. There was now no trouble in picking a quarrel with Austria. Bismarck suggested the nominal independence of the duchies, but that they should become practically a part of Prussia. This plan was of course indignantly rejected by Austria, and it was arranged that, pending an adjustment, Austria should govern Holstein, and Prussia, Schleswig.
Prussia declares the German Confederation dissolved.
Bismarck now obtained the secret assurance of Napoleon III that he would not interfere if Prussia and Italy should go to war with Austria. In April, 1866, Italy agreed that, should the king of Prussia take up arms during the following three months with the aim of reforming the German union, it too would immediately declare war on Austria, with the hope, of course, of obtaining Venice. The relations between Austria and Prussia grew more and more strained, until finally in June, 1866, Austria induced the diet to call out the forces of the confederation with a view of making war on Prussia. This act the representative of Prussia declared put an end to the existing union. He accordingly submitted to the diet Prussia's scheme for the reformation of Germany and withdrew from the diet.
War declared between Prussia and Austria.
271. On June 12 war was declared between Austria and Prussia. With the exception of Mecklenburg and the small states of the north, all Germany sided with Austria against Prussia. Bismarck immediately demanded of the rulers of the larger North German states—Hanover, Saxony, and Hesse-Cassel—that they stop their warlike preparations and agree to accept Prussia's plan of reform. On their refusal, Prussian troops immediately occupied these territories, and war actually began.
Prussia victorious.
So admirable was the organization of the Prussian army that, in spite of the suspicion and even hatred which the liberal party in Prussia entertained for the despotic Bismarck, all resistance on the part of the states of the north was promptly prevented, Austria was miserably defeated on July 3 in the decisive battle of Königgrätz, or Sadowa,[452] and within three weeks after the breaking off of diplomatic relations the war was practically over. Austria's influence was at an end, and Prussia had won her right to do with Germany as she pleased.
The North German Federation.
Prussia was aware that the larger states south of the Main River were not ripe for the union that she desired. She therefore organized a so-called North German Federation, which included all the states north of the Main. Prussia had seized the opportunity considerably to increase her own boundaries and round out her territory by annexing the North German states, with the exception of Saxony, that had gone to war with her. Hanover, Hesse-Cassel, Nassau, and the free city of Frankfurt, along with the duchies of Schleswig and Holstein, all became Prussian.
