Into this world burst the Mongol. All his early years Genghis Khan spent in obtaining first the control of his own tribe, and then in establishing the absolute supremacy of this tribe over all its neighbors. In the first decade of the thirteenth century this work was accomplished. His supremacy over the wild mounted herdsmen was absolute and unquestioned. Every formidable competitor, every man who would not bow with unquestioning obedience to his will, had been ruthlessly slain, and he had developed a number of able men who were willing to be his devoted slaves, and to carry out his every command with unhesitating obedience and dreadful prowess. Out of the Mongol horse-bowmen and horse-swordsmen he speedily made the most formidable troops then in existence. East, west and south he sent his armies, and under him and his immediate successors the area of conquest widened by leaps and bounds; while two generations went by before any troops were found in Asia or Europe who on any stricken field could hold their own with the terrible Mongol horsemen, and their subject-allies and remote kinsmen, the Turko-Tartars who served with and under them. Few conquests have ever been so hideous and on the whole so noxious to mankind. The Mongols were savages as cruel as they were brave and hardy. There were Nestorian Christians among them, as in most parts of Asia at that time, but the great bulk of them were Shamanists; that is, their creed and ethical culture were about on a par with those of the Comanches and Apaches of the nineteenth century. They differed from Comanche and Apache in that capacity for military organization which gave them such terrible efficiency; but otherwise they were not much more advanced, and the civilized peoples who fell under their sway experienced a fate as dreadful as would be the case if nowadays a civilized people were suddenly conquered by a great horde of Apaches. The ruthless cruelty of the Mongol was practised on a scale greater than ever before or since. The Moslems feared them as much as the Christians. They put to death the Caliph, and sacked Bagdad, just as they sacked the cities of Russia and Hungary. They destroyed the Turkish tribes which ventured to resist them with the merciless thoroughness which they showed in dealing with any resistance in Europe. They were inconceivably formidable in battle, tireless in campaign and on the march, utterly indifferent to fatigue and hardship, of extraordinary prowess with bow and sword. To the Europeans who cowered in horror before them, the squat, slit-eyed, brawny horsemen, “with faces like the snouts of dogs,” seemed as hideous and fearsome as demons, and as irresistible by ordinary mortals. They conquered China and set on the throne a Mongol dynasty. India also their descendants conquered, and there likewise erected a great Mongol empire. Persia in the same way fell into their hands. Their armies, every soldier on
