Wang Khan’s skull, encased in silver, graced the conqueror’s tent as a first trophy. In 1206, summoning all the Mongol chiefs, Temugin took the title of Genghis Khan, “The Greatest King.” His armies were turned next to the reduction of his own people, the nomad tribes of the Central Asian plains. As one after another was defeated, its warriors were incorporated into his growing army. When all these myriad shepherds and soldiers were gathered in, he directed his march towards China. The Great Wall was as paper to his host. Ninety cities were taken by storm, never one surrendering. For while to the kindred races which he had conquered, and which furnished further recruits for his armies, Genghis was most merciful and humane, to a foreign foe he was indeed the Wrath of God. Once he was bought off from the invasion; but again he returned to the prey. A way into Peking was opened by means of a mine dug under the walls to the centre of the city; through it a picked body of Mongols entered, marched to the gates, and opened them. The savage host rushed in to sack and slay. For sixty days Peking burned, and five desolated provinces of North China were added to the Mongol Empire. Mohammed, Sultan of Carizme, who reigned from India to the Persian Gulf, was the next objective for the Mongols. In the field, by valor and numbers, the Khan’s troops defeated all the Sultan’s armies. The walled towns were besieged and taken, largely through the skill of Chinese engineers. The whole great Persian district was harried after the custom of the Mongols through four years; for hundreds of miles the country was so ruined that to this day the old populousness and prosperity have never been recovered. The army of one of the Khan’s generals marched north into Turkestan, and subduing many Turkish peoples, entered beyond the Caucasus the territory of the Polovtisni, themselves Mongols of an earlier invasion. The conquest of Russia had begun. A Muscovite chronicle of those days illustrates the utter consternation and surprise of the inhabitants at this formidable and sudden incursion: “In those times there came upon us, for our sins, unknown nations. No one could tell their origin, whence they came, or what religion they professed. God alone knew who they were.” The people generally believed that the time had come foretold in Revelation when Satan should be let loose with the hosts of “Gog and Magog to gather them together in battle; the number of whom is as the sand of the sea.” Indeed, in the old map of Tatary, by Hondius, the territories of these two fabled worthies are carefully outlined in what is now Manchuria.
