In 1853 the Tsar sent Prince Menshikov to Constantinople in order to demand a formal treaty granting the Greek Church religious independence and temporal privileges. The Sublime Porte, backed by France and England, rejected the ultimatum. The latter Powers then sent a fleet to the Dardanelles, and the next month—on July 4, 1853—Russia occupied Moldavia and Wallachia. At the instigation of Austria, the Powers assembled at Vienna on the 24th of the same month drew up a conciliatory note, which was rejected by Russia. Then the English fleet sailed up the Dardanelles, and on October 4 Turkey declared war on Russia. Austria tried again, at the Vienna Conference which she reopened in December, 1853, to bring about an understanding between Russia and Turkey. But Nicholas I declared that he meant to treat only with England and Prussia to restore peace in the East, which Turkey looked upon as an affront. He also rejected Napoleon III’s mediation on January 29, 1854, and the Franco-English summons on February 27, upon which France declared war on him. Notwithstanding the political views which unfortunately are still held by most of the present diplomatists, and in pursuance of which the Powers had already checked Mehemet Ali’s success and prevented Turkey resuming her former state, France and England realised the dangerous consequences of the Russian threat and backed Turkey. In consequence of the manœuvres of Austria and the unwillingness of Prussia, who had declared “she would never fight against Russia,” the Allies, who were at Varna, instead of attacking the principalities, decided to launch into the Crimean expedition. Finally, after the ultimatum drawn up by Austria, to which the Emperor Alexander submitted at the instigation of Prussia, a treaty of peace signed in Paris on March 30, 1856, recognised the integrity of Turkey, abolished the Russian protectorate over the principalities, and guaranteed the independence of Serbia, Moldavia, and Wallachia, under the suzerainty of the Ottoman Empire. Our diplomats seem then to have partly realised the extent of the danger constituted by the Slavs, and to have understood that the Turks, by driving back the Slavs and keeping them away from Western and Mediterranean Europe since the fourteenth century, had enabled Western civilisation to develop. As the influence of France in Turkey was imperilled after her defeat in 1870, Russia took advantage of this to declare she would no longer submit to the most important clauses of the London treaty of March 13, 1871. Russia, whose ambassador in Turkey at that time was General Ignatiev, took in hand the cause of the independence of the Bulgarian Church, for which, in 1870, she had obtained the creation of a national exarchate with its own hierarchy, which had exasperated the Phanar at Constantinople and brought about deadly encounters between Turks and Bulgarians.
