A pretence for hastening the dissolution of the sick man was not long wanting. A quarrel between the Greek and Latin Christians at Jerusalem about the holy places was made the ground by Nicholas for demanding of the Sultan the admission and recognition of a Russian protectorate over all Greek Christians in the Ottoman dominions. The demand was rejected, and Nicholas prepared for war.

The Sultan appealed to the Western powers for help. England and France responded to the appeal, and later Sardinia joined her forces to theirs. England, rejecting the Czar's proposal of a division of the dying man's estate, fought to prevent Russia from getting through the Bosporus to the Mediterranean, and thus endangering her route to her Eastern possessions. The French emperor fought to avenge Moscow, and to render his new imperial throne attractive to his people by surrounding it with the glamour of successful war. Sardinia was led to join England and France through the policy of the far-sighted Cavour, who would thus have the Sardinians win the gratitude of these powers, so that in the next conflict with Austria the Italian patriots might have some strong friends to help them.

The main interest of the struggle centred about Sebastopol, in the Crimea, Russia's great naval and military depot, and the key to the Euxine. Around this strongly fortified place were finally gathered 175,000 soldiers of the allies. The siege, which lasted eleven months, was one of the most memorable and destructive in history. The Russian engineer Todleben earned a great fame through his masterly defence of the works. The English "Light Brigade" earned immortality in their memorable charge at Balaklava. The French troops, through their dashing bravery, brought great fame to the emperor who had sent them to gather glory for his throne.

The Russians were at length forced to evacuate the place. They left it, however, a "second Moscow." The war was now soon brought to an end by the Treaty of Paris (1856). Every provision of the treaty had in view the maintenance of the integrity of the empire of the Sultan, and the restraining of the ambition of the Czar. Russia was given back Sebastopol, but was required to give up some territory at the mouth of the Danube, whereby her frontier was pushed back from that river; to abandon all claims to a protectorate over any of the subjects of the Porte; to agree not to raise any more fortresses on the Euxine nor keep upon that sea any armed ships, save what might be needed for police service. The Christian population of the Turkish dominions were placed under the guardianship of the great powers, who were to see that the Sublime Porte fulfilled its promise of granting perfect civil and religious equality and protection to all its subjects.

EMANCIPATION OF THE SERFS (1858-1863).—Alexander II. (1855-1881), who came to the Russian throne in the midst of the Crimean War, abandoned the narrow and intolerant system of his predecessor Nicholas, and reverting as it were to the policy of Peter the Great, labored for popular reform, and for the introduction into his dominions of the ideas and civilization of Western Europe. The reform which will ever give his name a place in the list of those rulers who have conferred singular benefits upon their subjects, was the emancipation, by a series of imperial edicts, of the Russian serfs, who made up more than 45,000,000 of the population of the empire. More than half of these serfs belonged to the Crown, and were known as Crown peasants.

The Crown serfs were only nominal bondsmen, their servitude consisting in scarcely more than the payment of a light rent. The serfs of individual proprietors, however, might be designated as semi-slaves. Thus, their owners could flog them in case of disobedience, but could not sell them individually as slaves are sold; yet when a proprietor sold his estate, the whole community of serfs living upon it passed with it to the purchaser.

Besides the emancipation measure, Alexander's name is associated with other reforms, the earlier part of his reign especially being characterized by a very liberal spirit. This liberal policy was followed until the revolt of the Poles in 1863, when Alexander was led to adopt a more reactionary policy, a policy which persistently pursued has yielded bitter fruit in Nihilism.

THE RUSSO-TURKISH WAR OF 1877-1878.—Anxiously as the Treaty of Paris had provided for the permanent settlement of the Eastern Question, barely twenty-two years had passed before it was again up before Europe, and Russia and Turkey were again in arms. The Sultan could not or would not give to his Christian subjects that equal protection of the laws which he had solemnly promised should be given. The Moslem hatred of the Christians was constantly leading to disturbance and outrage. In 1860 there was a great massacre of Syrian Christians by the Druses and Turks, and in 1876 occurred in Bulgaria the so-called "Bulgarian atrocities," massacres of Christian men, women, and children, more revolting perhaps than any others of which history tells. The greatest indignation was kindled throughout Europe. The Russian armies were set in motion (1877). Kars in Asia Minor and Plevna in European Turkey fell into the hands of the Russians, and the armies of the Czar were once more in full march upon Constantinople, with the prospect of soon ending forever Turkish rule on European soil, when England, as in 1829, interfered, and by the movements of her iron-clads in the Bosporus again arrested the triumphant march of the Russians.
