In February, 1864, Prussia and Austria together declare war upon Denmark over the Schleswig-Holstein succession. They agree to govern the spoils between them, but fall out over the question of their respective jurisdiction, and the Prussian army being ready, and the Moltke plan of campaign worked out, war is declared, and in seven weeks the Treaty of Prague is signed, in 1866, by which Austria gives up all her rights in Schleswig-Holstein, and abandons her claim to take part in the reorganization of Germany. The North German Confederation is formed to include all lands north of the Main; Schleswig-Holstein, Hanover, the Hesse states, Nassau, and Frankfurt-am- Main become part of Prussia; and the south German states agree to remain neutral, but allies of Prussia in war. On the 11th of March, 1867, a month after the formation of the Confederation of the North German States, Bismarck proclaims with pride in the new Reichstag: "Setzen win Deutschland, so zu sagen, in den Sattel! Reiten wird es schon koennen!" October 13th, 1868, Leopold von Sigmaringen, a German prince of the House of Hohenzollern, is named for the first time as a candidate for the Spanish throne. Nobody in Germany, or anywhere else, was much more interested in this candidature, than we are now interested in the woman's suffrage or the prohibition candidate at home. But France had looked on with jealous eyes at the vigorous growth and martial successes of Prussia. It was thought well to attack her and humiliate her before she became stronger. All France was convinced, too, that the southern German states would revert to their old love in case of actual war, and side with the nephew of their former friend, the great Napoleon. The French ambassador is instructed to force the pace. Not only must the Prussian King disavow all intention to support the candidacy of the German prince, but he must be asked to humiliate himself by binding himself never in the future to push such claims.
