Politically speaking these new states of the great Russian plains did not fare well. It was the Norse habit to divide every inheritance equally among all the sons. No sooner had a small state been founded but it was broken up among eight or nine heirs who in turn left their territory to an ever increasing number of descendants. It was inevitable that these small competing states should quarrel among themselves. Anarchy was the order of the day. And when the red glow of the eastern horizon told the people of the threatened invasion of a savage Asiatic tribe, the little states were too weak and too divided to render any sort of defence against this terrible enemy. It was in the year 1224 that the first great Tartar invasion took place and that the hordes of Jenghiz Khan, the conqueror of China, Bokhara, Tashkent and Turkestan made their first appearance in the west. The Slavic armies were beaten near the Kalka river and Russia was at the mercy of the Mongolians. Just as suddenly as they had come they disappeared. Thirteen years later, in 1237, however, they returned. In less than five years they conquered every part of the vast Russian plains. Until the year 1380 when Dmitry Donskoi, Grand Duke of Moscow, beat them on the plains of Kulikovo, the Tartars were the masters of the Russian people. All in all, it took the Russians two centuries to deliver themselves from this yoke. For a yoke it was and a most offensive and objectionable one. It turned the Slavic peasants into miserable slaves. No Russian could hope to survive unless he was willing to creep before a dirty little yellow man who sat in a tent somewhere in the heart of the steppes of southern Russia and spat at him. It deprived the mass of the people of all feeling of honour and independence. It made hunger and misery and maltreatment and personal abuse the normal state of human existence. Until at last the average Russian, were he peasant or nobleman, went about his business like a neglected dog who has been beaten so often that his spirit has been broken and he dare not wag his tail without permission. There was no escape. The horsemen of the Tartar Khan were fast and merciless. The endless prairie did not give a man a chance to cross into the safe territory of his neighbour. He must keep quiet and bear what his yellow master decided to inflict upon him or run the risk of death. Of course, Europe might have interfered. But Europe was engaged upon business of its own, fighting the quarrels between the Pope and the emperor or suppressing this or that or the other heresy. And so Europe left the Slav to his fate, and forced him to work out his own salvation.
