to gain time to prepare the ground for the supreme struggle with Austria for the hegemony of Germany. He had no intention of postponing the issue long; for the circumstances of the two powers were wholly favourable to Prussia. The Prussian army had attained an unprecedented excellence of organization and discipline; the Prussian people, in spite of the parliamentary deadlock, were loyal and united; while in Austria army and state were alike disorganized by nationalist discontent and the breakdown of the centralized system. But there were other factors to be considered. The attitude of Napoleon was dubious; the active alliance of Italy was necessary to the certainty of Prussian success; and the policy of Italy depended ultimately upon that of France. Lastly, the conscience of King William, though since the acquisition of Lauenburg he had “developed a taste for conquest,” shrank from provoking war with a German power. The news of the convention of Gastein, which seemed Hostile attitude of France. to re-cement the union of Germany, had been received in France with clamorous indignation; and on the 29th of August, under pressure of public opinion, the French government issued a circular note denouncing it as an outrage on national liberty and European law, the protest being backed by note of the 14th of September circulated by Lord John Russell on behalf of the British government. But Napoleon was himself little inclined to use the warlike tone of his people; and Bismarck found it easy to win him over to his views by explaining the temporary nature of the convention, and by dropping hints at the famous interview at Biarritz (September 30, 1865) of possible “compensations” to France in the event of a Prussian victory over Austria; the probability of a prolonged struggle in Germany between two powers apparently evenly matched, moreover, held out to the French emperor the prospect of his being able to intervene at the proper moment with overwhelming effect.
Napoleon having been successfully hoodwinked, Bismarck turned to Italy. His previous advances had been interrupted by the Gastein convention, which seemed to the Italian government a betrayal of the Italian cause. Italy End of the Austro-Prussian understanding. attempted to negotiate with Austria for the purchase of Venetia; but the offer was curtly refused by the emperor Francis Joseph, and the counter-proposal of a commercial rapprochement was forestalled by Prussia, which with the aid of most of the lesser states, angered by the betrayal of their interests by Austria at Gastein, arranged a commercial treaty between Italy and the Zollverein, an act which involved the recognition of the Italian kingdom. The counter-stroke of Austria was to embarrass Prussia by allowing full play in Holstein to the agitation in favour of the Augustenburg claimant. To the protests of Prussia, Austria replied that she had a full right to do what she liked in the duchy, and that she still adhered to the declaration of the princes, made on the 28th of May 1864, in favour of Duke Frederick. This “perfidy” removed the last scruples of King William; and the Austro-Prussian alliance came to an end with the declaration of Bismarck that Prussia “must win full freedom for her own entire policy” and his refusal to continue the correspondence.
War, though still postponed, was now certain; and with this certainty the desire of the Italians for the Prussian alliance, now recommended by Napoleon, revived. By the 16th of March 1866 the Austrian war preparations were so far advanced that Count Mensdorff thought it safe to send an ultimatum to Prussia and, at the same time, a circular note to the princes declaring that, in the event of an evasive reply, Austria would move in the diet for the mobilization of the federal forces. On the 24th Bismarck in his turn issued a circular note stating that, in view of the Austrian war preparations, Prussia must take measures for her defence; at the same time he laid before the princes the outline of the Prussian scheme for the reform of the Confederation, a scheme which included a national parliament to be elected by universal suffrage, “as offering surer guarantees for conservative action than limitations that seek to determine the majority beforehand.” Clearly Prussia meant war, and the Italian government thought it safe to sign, on the 8th of April 1866, a treaty of alliance. By this instrument it was agreed that in Prusso-Italian alliance. the event of her proposals for the reform of the federal constitution being rejected by the German princes, Prussia should declare war “in order to give effect to her proposals,” and that, in that case, Italy would also declare war against Austria. As a result of the war Venetia was to be added to Italy and an equivalent amount of territory in North Germany to Prussia. The agreement, however, was only to hold good if war broke out within three months.
On the day after the signature of the treaty the Prussian project of reform was presented to the federal diet. It was, however, no more than a bid for the support of public opinion on the part of Bismarck; for even while it was Prussian scheme for the reform of the “Bund.” under discussion an angry correspondence was being carried on between Berlin and Vienna on the question of armaments, and by the beginning of May both powers were making undisguised preparations for war. On the 21st of April, the very day when the discussion of the Prussian proposals began in the diet, Austria, alarmed at a threatened attack by Garibaldi on Venetia, began to mobilize in defiance of an agreement just arrived at with Prussia. Five days later, in spite of this, she sent an ultimatum to Berlin, demanding the continuance of the Prussian disarmament and an immediate settlement of the Schleswig-Holstein question. The supreme issue was, however, delayed for a few weeks by the intervention of Napoleon, who, urged on by the loud alarm of the French people at the prospective aggrandizement of Prussia, attempted to detach Italy from the Prussian alliance by persuading Austria to a cession of Venetia. The negotiations broke down on the refusal of Italy to throw over her ally, and Napoleon’s proposal of a European congress, to reconsider the whole settlement under the treaties of 1815, proved equally abortive. Meanwhile the preparations for war had been continued, and on the 1st of June Austria flung down the gage by declaring her intention of submitting the whole question of the duchies to the federal diet and of summoning a meeting of the Holstein estates. This was denounced by Bismarck in a circular note to the powers as a breach of the convention of Gastein and of the treaty of January 16, 1864, by which Austria and Prussia had agreed to govern the duchies in common. At the same time he handed in the formal protest of Prussia to the federal diet. Prussia, he said, would only recognize the right of a reformed federal power to settle the Schleswig-Holstein question, and this power must be based on a German parliament, which alone could guarantee Prussia that any sacrifices she might make would be for the good of Germany and not of the dynasties. The Prussian plan of reform laid before the diet included the exclusion of Austria from the Confederation; the creation of a federal navy; the division of the supreme command of the army between Prussia and Bavaria; a parliament elected by manhood suffrage; the regulation of the relations between the Confederation and Austria by a special treaty. In the event of the actual constitution of the Bund being shattered by war, the German states were asked whether they would be prepared to join this new organization. On the 9th of June Prussian troops had already marched into Holstein, the Austrians, with Duke Frederick, falling back on Altona. On the 14th the Prussian scheme of reform was laid before the diet, together with Austria’s counter-proposal for a decree of federal execution against Prussia. In the event of the rejection of Prussia’s motion, Bismarck had made it clear that Prussia withdraws from the “Bund.” Prussia would withdraw from the Confederation, and that in the event of her being victorious in the ensuing war those states of northern Germany that voted against her would cease to exist. In spite of this, the Austrian motion was carried by nine votes to six. The Prussian delegate at once withdrew from the diet, and on the following day (June 15) the Prussian troops advanced over the Saxon frontier.
The war that followed, conveniently called the Seven Weeks' War (q.v.), culminated before a month had passed, on the 3rd Austro-Prussian War of 1866. of July, in the crushing Prussian victory of Königgrätz. The rapidity and overwhelming character of the Prussian success
