The instinct against race-mixture which Nature has implanted in man is the great safeguard of the work of evolution to a higher type. The White Race, having developed on certain lines to a position which promises, if it does not fulfil, the evolution of a yet higher type, has an instinctive repugnance to mixing its blood with peoples in other stages of evolution. It is this instinct, this transcendental instinct, which is responsible for the objection to miscegenation in the United States, and for the lynchings by which that objection is impressed upon the negro mind. The same instinct is at the back of the "White Australia" laws, forbidding coloured people any right of entry into Australia.
It is not difficult to argue from a point of view of Christian religion and humanity against an instinct which finds its extreme, but yet its logical, expression in the burning of some negro offender at the stake. But all the arguments in the world will not prevail against Nature. Once a type has won a step up it must be jealous and "selfish," and even brutal in its scorn of lower types; or must climb down again. This may not be good ethics, but it is Nature. Russian backwardness in civilisation to-day is a living proof that the scorn of the coloured man is a necessary condition of the progress of the White Man's civilisation.
But the race-mixture which was of evil to Russia has been of benefit to the rest of Europe. To borrow a metaphor from modern preventive medicine, the Russian marches between Europe and Asia have had their power of resistance to Yellow invasion strengthened by the infusion of some Yellow blood.
A land of high steppes, very cold in winter, very hot in summer, and of great forests, which were difficult to traverse except where the rivers had cut highways, Russia was never so tempting to the early European civilisations as to lead to her area being definitely occupied and held as a province. Neither Greek nor Roman attempted much colonisation in Russia. By general consent the country was left to be a No-Man's-Land between Asia and Europe. Alexander, whose army penetrated through to India and actually brought back news of the existence of Australia, never marched far north into the interior of Russia. There the mixed tribes of Finns, Aryans, Semites, Mongols held a great gloomy country influenced little by civilisation, but often temporarily submerged by waves of barbarians from the Asiatic steppes. Still Western Europe in time made some little impression on the Russian mass. Byzantine culture impressed its mark on the Southern Slavs; Roman culture, after filtering through Germany, reached the Lithuanians of the north. In the twelfth century we hear of Arabian caravans making their way as far as the Baltic in search of amber.
But more important to the Russian civilisation was the advent of the Normans in the ninth century. They consolidated White Russia during the ninth to the thirteenth centuries, appeared as warriors before the walls of Byzantium, and learned the Christian faith from the priests of the Eastern communion. (Russia has since been faithful always to the Greek Church.) That period was rich in national heroes, such as Rurik, Simeon and Truvor, and definitely set the current of Russian national life towards a place in the European family of nations. By the thirteenth century the White Russians, with their capital established at Moscow, were able to withstand for a while a new Mongol invasion. But they could not prevent Gengis Khan's lieutenants establishing themselves on the lower Volga, and the Grand Prince of Moscow had to be content to become a suzerain of the Grand Khan of Tartary.
For three centuries Russia now, amid many troubles, prepared herself to take a place amongst European Powers. She was still more or less subject to the Asiatic. But she was not Asiatic, and her vast area stood between Europe and Asia and allowed the more Western nations to grow up free from interference from any Eastern people, except in the case of the great invasion of the Turks coming up from the south-east. How great was the service that Russia unconsciously did to civilisation during those centuries! If the Tartar had come with the Turk, or had followed him, the White Races and their civilisation might have been swept away.
After being the bulwark of Europe for centuries Russia at last found her strength and became the avenger of the White Races. By the sixteenth century the Russian power had been consolidated under the Muscovite Czars, and a great nation, of which the governing class was altogether European, began to push back the Asiatic. From the sixteenth to the nineteenth centuries the Russian Power grew. The natural direction of expansion was southward. The new nation wanted a place in the sun, and looked longingly towards the Mediterranean. Only the Turk stood in the path, and for the Russian Czars war with the Turk had something of a religious attraction. It was the Cross against the Crescent. It was the champion of the Greek Church winning back the Byzantine Empire to Christian domination.
For Russia to march south, driving the infidel from Europe, freeing the Greeks, establishing herself in Constantinople, winning warm-water ports and warm-climate fields, seemed to the Russian mind a national policy which served both God and Mammon. That it served God was no slight thing to the Russian people. They, then as now, cherished a simplicity and a strenuousness of faith which may be called "superstitious" or "beautiful and childlike" as the observer may wish, but which is undoubtedly sincere. "There has been only one Christian," wrote Heine. If he had known the Russians he would have qualified the gibe. They have a real faith, and it is an important factor in the making of their national policy which has to be taken into account.
How much there was of religious impulse and how much of mere materialistic national ambition in Russia's move southward did not in the least concern other European Powers. Whatever its motive they considered the development dangerous. It threatened to give the Russian an overwhelming power, a paramountcy in Europe, and that could not be tolerated even if it had the most worthy of motives. Above all, Great Britain was alarmed. In the days of Elizabeth Great Britain had been a very good friend to Russia. But Russia was then no possible rival either on land or on the high seas. In the days of Victoria the position had changed. Russia still wore the laurels of her "victories" over Napoleon. She was credited with being the greatest military Power in the world, and credited also with a relentless and Machiavellian diplomacy that added vastly to the material resources of her armies and fleets.
The Crimean War, with its resulting humiliating restrictions on Russian power in the Black Sea, taught Russia that Europe was determined to block her path south and preferred to buttress Turkish misrule than to permit Russian expansion. Baffled but still restless, Russia turned east and marched steadily towards the Pacific, with a side glance at the Persian Gulf and the Indian Ocean, which caused Great Britain fresh apprehension as to the fate of India.
