Farther east, towards the Balkan Peninsula, the expansive tendency is much more complicated and of very ancient date. The Russo-Slavs who held the valley of the Dnieper from the ninth to the thirteenth century belonged to those numerous frontier tribes which the tottering Byzantine Empires attempted to ward off by diplomacy and rich gifts, and by giving to the troublesome chiefs, on condition of their accepting Christianity, princesses of the Imperial family as brides. Vladimir, Prince of Kief, now recognised as a Saint by the Russian Church, accepted Christianity in this way (A. D. 988), and his subjects followed his example. Russia thus became ecclesiastically a part of the Patriarchate of Constantinople, and the people learned to regard Tsargrad--that is, the City of the Tsar, as the Byzantine Emperor was then called--with peculiar veneration.
All through the long Tartar domination, when the nomadic hordes held the valley of the Dnieper and formed a barrier between Russia and the Balkan Peninsula, the capital of the Greek Orthodox world was remembered and venerated by the Russian people, and in the fifteenth century it acquired in their eyes a new significance. At that time the relative positions of Constantinople and Moscow were changed. Constantinople fell under the power of the Mahometan Turks, whilst Moscow threw off the yoke of the Mahometan Tartars, the northern representatives of the Turkish race. The Grand Prince of Moscow thereby became the Protector of the Faith, and in some sort the successor of the Byzantine Tsars. To strengthen this claim, Ivan III. married a niece of the last Byzantine Emperor, and his successors went further in the same direction by assuming the title of Tsar, and inventing a fable about their ancestor Rurik having been a descendant of Caesar Augustus.
All this would seem to a lawyer, or even to a diplomatist, a very shadowy title, and none of the Russian monarchs--except perhaps Catherine II., who conceived the project of resuscitating the Byzantine Empire, and caused one of her grandsons to learn modern Greek, in view of possible contingencies--ever thought seriously of claiming the imaginary heritage; but the idea that the Tsars ought to reign in Tsargrad, and that St. Sophia, polluted by Moslem abominations, should be restored to the Orthodox Christians, struck deep root in the minds of the Russian people, and is still by no means extinct. As soon as serious disturbances break out in the East the peasantry begin to think that perhaps the time has come for undertaking a crusade for the recovery of the Holy City on the Bosphorus, and for the liberation of their brethren in the faith who groan under Turkish bondage.
Essentially different from this religious sentiment, but often blended with it, is a vague feeling of racial affinity, which has long existed among the various Slav nationalities, and which was greatly developed during last century by writers of the Panslavist school. When Germans and Italians were striving after political independence and unity, it naturally occurred to the Slavs that they might do likewise. The idea became popular among the subject Slav nationalities of Austria and Turkey, and it awoke a certain amount of enthusiasm in Moscow, where it was hoped that "all the Slav streams would unite in the great Russian Sea." It required no great political perspicacity to foresee that in any confederation of Slav nationalities the hegemony must necessarily devolve on Russia, the only Slav State which has succeeded in becoming a Great Power.
Those two currents of national feeling ran parallel to, and intermingled with, the policy of the Government. Desirous of becoming a great naval Power, Russia has always striven to reach the sea-coast and obtain good harbours. In the north and north-
west she succeeded in a certain degree, but neither the White Sea nor the Baltic satisfied her requirements, and she naturally turned her eyes to the Mediterranean. With difficulty she gained possession of the northern shores of the Black Sea, but her designs were thereby only half realised, because the Turks held the only outlet to the Mediterranean, and could effectually blockade, so far as the open sea is concerned, all her Black Sea ports, without employing a single ship of war. Thus the possession of the Straits, involving necessarily the possession of Constantinople, became a cardinal point of Russia's foreign policy. Any description of the various methods adopted by her at different times for the attainment of this end does not enter into my present programme, but I may say briefly that the action of the three factors above mentioned--the religious feeling, the Panslavist sentiment, and the political aims--has never been better exemplified than in the last struggle with Turkey, culminating in the Treaty of San Stefano and the Congress of Berlin.
