But this awoke England. On February 13, the British fleet passed (p. 234) through the Dardanelles without obtaining the sultan's consent, and thereby ruined Russia's schemes. In vain did its government complain of the violation of the Treaty of Paris; before the czar could make good his threat that he would occupy Constantinople,--the object of the Russian's most fervid hope,--a fleet of British ironclads prevented its consummation. Peace negotiations were opened at San Stefano, when Russia imposed exaggerated demands which the cunning sultan hastened to grant, convinced that the other powers would prevent their execution. He was right. Great Britain, Austria, and Turkey entered into an alliance. England sent for Indian troops to occupy Malta, and called out the reserves. The war had cost Russia $600,000,000 and 90,000 men, and she was not in a condition to fight the three powers. Thus, for the second time, Czargrad slipped out of Russia's clutches, and each time she owed the disappointment to Great Britain. The Balkan question was settled at the Congress at Berlin which opened on June 13, 1878, and finished its sessions a month later. Turkey ceded to Russia a part of Bessarabia, and in Asia, Kars, Ardahan, and Batoum. This ending of the war, so different from what was expected by the Slavophils, caused great dissatisfaction in Russia, and the czar dissolved all Slavophil committees. This gained him the dislike of the high officers and of the tchinovnik. The absurd and dangerous doctrine of nihilism, that is, the destruction of everything that constitutes society, penetrated into Russia by way of Germany. At first it was nothing but a theory, fascinating for (p. 235) young and inexperienced people such as students of the universities who, unless properly guided, are apt to adopt any idea that appeals to the generous sentiments of youth. In 1864, an exile named Bakunin escaped from Siberia, and made his way to London where he secured employment on the _Kolokol_ or "Bell," a revolutionary paper published in Russia which was smuggled over the frontier and scattered broadcast in the czar's domains. Under Bakunin's influence this paper became hostile to society, and preached nihilism. In 1869, a Congress of Nihilists was held at Basel, Switzerland; Bakunin proposed to create an International Committee of active workers.
