This, however, merely signified that the signatory Powers would resist encroachments on the territorial integrity of Turkey. It did not limit the rights of the Powers, as specified in various "Capitulations," to safeguard their own subjects residing in Turkey against Turkish misrule. The Sultan raised great hopes by issuing a firman granting religious liberty to his Christian subjects; this was inserted in the Treaty of Paris, and thereby became part of the public law of Europe. The Powers also became _collectively_ the guarantors of the local privileges of the Danubian Principalities. Another article of the Treaty provided for the exclusion of war-ships from the Black Sea. This of course applied specially to Russia and Turkey[88]. [Footnote 88: For the treaty and the firman of 1856, see _The European Concert in the Eastern Question, _by T.E. Holland; also Débidour, _Histoire diplomatique de l'Europe _(1814-1878), vol. ii. pp. 150-152; _The Eastern Question, _by the late Duke of Argyll, vol. i. chap. i.] The chief diplomatic result of the Crimean War, then, was to substitute a European recognition of religious toleration in Turkey for the control over her subjects of the Greek Church which Russia had claimed. The Sublime Porte was now placed in a stronger position than it had held since the year 1770; and the due performance of its promises would probably have led to the building up of a strong State. But the promises proved to be mere waste-paper. The Sultan, believing that England and France would always take his part, let matters go on in the old bad way. The natural results came to pass. The Christians showed increasing restiveness under Turkish rule. In 1860 numbers of them were massacred in the Lebanon, and Napoleon III. occupied part of Syria with French troops. The vassal States in Europe also displayed increasing vitality, while that of Turkey waned. In 1861, largely owing to the diplomatic help of Napoleon III., Moldavia and Wallachia united and formed the Principality of Roumania. In 1862, after a short but terrible struggle, the Servians rid themselves of the Turkish garrisons and framed a constitution of the Western type. But the worst blow came in 1870. During the course of the Franco-German War the Czar's Government (with the good-will and perhaps the active connivance of the Court of Berlin) announced that it would no longer be bound by the article of the Treaty of Paris excluding Russian war-ships from the Black Sea. The Gladstone Ministry sent a protest against this act, but took no steps to enforce its protest. Our young diplomatist, Sir Horace Rumbold, then at St. Petersburg, believed that she would have drawn back at a threat of war[89]. Finally, the Russian declaration was agreed to by the Powers in a Treaty signed at London on March 31, 1871.
