Though, however, Austria by her diplomatic attitude had secured, without striking a blow, the settlement in her sense of the Eastern Question, she emerged from the contest without allies and without friends. The "Holy Alliance" of the three autocratic northern powers, recemented at Münchengrätz in 1833, which had gained for Austria the decisive intervention of the tsar in 1849, had been hopelessly shattered by her attitude during the Crimean War. Russia, justly offended, drew closer her ties with Prussia, where Bismarck was already hatching the plans which were to mature in 1866; and, if the attitude of Napoleon in the Polish question prevented any revival of the alliance of Tilsit, the goodwill of Russia was assured for France in the coming struggle with Austria in Italy. Already the isolation of Austria had been conspicuous in the congress of Paris, where Cavour, the Sardinian plenipotentiary, laid bare before assembled Europe the scandal of her rule in Italy. It was emphasized during the campaign of 1859, when Sardinia, in alliance with France, laid the foundations of united Italy. The threat of Prussian intervention, which determined the provisions of the armistice of Villafranca, was due, not to love of Austria, but to fear of the undue aggrandizement of France. The campaign of 1859, and the diplomatic events that led up to it, are dealt with elsewhere (see ITALY, ITALIAN WARS, NAPOLEON III., CAVOUR). The results to Austria were two-fold. Externally, she lost all her Italian possessions except Venice; internally, her failure led to the necessity of conciliating public opinion by constitutional concessions.
The proclamation on the 26th of February 1861 of the new constitution for the whole monarchy, elaborated by Anton von Schmerling, though far from satisfying the national aspirations of the races within the empire, at least gave Austria a temporary popularity in Germany; the liberalism of the Habsburg monarchy was favourably contrasted with the "reactionary" policy of Prussia, where Bismarck was defying the majority of the diet in his determination to build up the military power of Prussia. The meeting of the princes summoned to Frankfort by the emperor Francis Joseph, in 1863, revealed the ascendancy of Austria among the smaller states of the Confederation; but it revealed also the impossibility of any consolidation of the Confederation without the co-operation of Prussia, which stood outside. Bismarck had long since decided that the matter could only be settled by the exclusion of Austria altogether, and that the means to this end were not discussion, but "Blood and Iron." The issue was forced by the developments of the tangled Schleswig-Holstein Question (_q.v._), which led to the definitive breach between the two great German powers, to the campaign of 1866, and the collapse of Austria on the field of Koniggratz (July 3. See SEVEN WEEKS' WAR).
