During the reigns of Nicholas I. and Alexander II. the German-Austrian influence reached its zenith at the Court of Petersburg. Nicholas I. was the brother-in-law of the Prussian Hohenzollern. An able and an honest man in his private relations, he was in his political capacity a Prussian martinet, as even Treitschke is compelled to admit, and he organized his Empire on the strictest Frederician principles. The Court, the Army, and the bureaucracy were Prussianized as they had never been before. A German bureaucrat, Nesselrode, who could not even speak the Russian language, for forty years controlled as Foreign Minister the policy of the Russian Empire. Even as his grandfather, Peter III., even as his brother, Alexander I., had saved Prussia from destruction, so Nicholas I. saved Austria from a similar fate. Francis Joseph had ascended a throne shaken to its foundations. Hungary was in open rebellion. The young Austrian Emperor appealed to Russia for help. Nicholas I. sent an army to quell the revolution, and established his cousin on the Hungarian throne. It is unnecessary to add that Francis Joseph was as loyal and as grateful to Russia as Frederick the Great had been!
Alexander I. had refused to accept Napoleon I. as a brother-in-law. Even so did Nicholas I. refuse to recognize Napoleon III. as Emperor of the French. It was a gratuitous insult inspired by Prussia; it was opposed to Russian interests, and it was one of the main causes of the Crimean War.
Under Alexander II. the alliance of the three reactionary empires of Central Europe was welded even more firmly than under his predecessor. Bismarck, during his tenure of the Prussian Embassy at Petersburg, was the chosen favourite of the Russian Court, and if he had chosen could have become a Minister of the Tsar. An understanding with Russia became the chief dogma of his political creed, and it remained so until the end. It was Bismarck’s adherence to the Russian-Prussian Alliance which was one of the causes of his dismissal.
Alexander II. did nothing to guard against the German peril. He might have been the umpire of Central Europe, as Alexander I. had been fifty years before. He demanded no compensation for the enormous accession of power and territory which Germany had received through the victorious wars of 1863, 1866, and 1870. He insisted on no guarantees. When, after Sedan, Thiers came to St. Petersburg to obtain the intervention of the Russian Empire, he was dismissed with empty words. One year after Thiers’s fruitless journey, Emperor William paid an official visit to his nephew Alexander II., and the Tsar once more proclaimed the indissoluble solidarity of Russia with Germany. Until the end of his reign the German-Austrian-Russian Alliance, the famous dynastic Alliance of the Three Emperors, remained the keystone of European policy and the mainstay of Russian reaction.
