Russia likewise remembered Napoleon III.’s championship of the Poles in 1863, which, however Platonic in its nature, caused the Czar some embarrassment.  Moreover, King William of Prussia had soothed the Czar’s feelings, ruffled by the dethroning of three German dynasties in 1866, by a skilful reply which alluded to his (King William’s) desire to be of service to Russian interests elsewhere—­a hint which the diplomatists of St. Petersburg remembered in 1870 to some effect.

For the rest, the Czar Alexander II. (1855-81) and his Ministers were still absorbed in the internal policy of reform, which in the sixties freed the serfs and gave Russia new judicial and local institutions, doomed to be swept away in the reaction following the murder of that enlightened ruler.  The Russian Government therefore pledged itself to neutrality, but in a sense favourable to Prussia.  The Czar ascribed the Crimean War to the ambition of Napoleon III., and remembered the friendship of Prussia at that time, as also in the Polish Revolt of 1863[11].  Bismarck’s policy now brought its reward.

The neutrality of Russia is always a matter of the utmost moment for the Central Powers in any war on their western frontiers.  Their efforts against Revolutionary France in 1792-94 failed chiefly because of the ambiguous attitude of the Czarina Catherine II.; and the collapse of Frederick William IV.’s policy in 1848-51 was due to the hostility of his eastern neighbour.  In fact, the removal of anxiety about her open frontier on the east was now worth a quarter of a million of men to Prussia.

But the Czar’s neutrality was in one matter distinctly friendly to his uncle, King William of Prussia.  It is an open secret that unmistakable hints went from St. Petersburg to Vienna to the effect that, if Austria drew the sword for Napoleon III. she would have to reckon with an irruption of the Russians into her open Galician frontier.  Probably this accounts for the conduct of the Hapsburg Power, which otherwise is inexplicable.  A war of revenge against Prussia seemed to be the natural step to take.  True, the Emperor Francis Joseph had small cause to like Napoleon III.  The loss of Lombardy in 1859 still rankled in the breast of every patriotic Austrian; and the suspicions which that enigmatical ruler managed to arouse, prevented any definite agreement resulting from the meeting of the two sovereigns at Salzburg in 1867.

The relations of France and Austria were still in the same uncertain state before the War of 1870.  The foreign policy of Austria was in the hands of Count Beust, a bitter foe of Prussia; but after the concession of constitutional rule to Hungary by the compromise (Ausgleich) of 1867, the Dual Monarchy urgently needed rest, especially as its army was undergoing many changes.  The Chancellor’s action was
