Eastern historians have praised Gengiskhan for having given laws to nations he had conquered. These laws, the aim of which was to maintain the peace of families, and to direct the minds of the people towards war, for a length of time retained the obedience and the respect of the Moguls. As Gengiskhan, in his legislation, acknowledged one God, the sovereign of the earth and heaven, and, at the same time, permitted all kinds of creeds, some modern writers have taken occasion to boast of his religious tolerance. But what could be the tolerance of a savage conqueror, who caused himself to be styled the son of the sun, the son of God; who himself followed no worship, and to whom all religions were equally indifferent, provided they crossed neither his ambition nor his pride?
The lieutenants and warriors of Gengiskhan had recognised him with the greater joy, as universal conqueror and master of the earth, from the hopes they entertained of enriching themselves with the spoils of all the nations subdued by his arms. His first enterprises were directed against China, of which empire he had been the vassal. Neither the barrier of the great wall, nor the ascendancy of knowledge and arts, nor the use of gunpowder, said to be then known among the Chinese, was able to defend a flourishing empire against the attacks of a multitude, whom the thirst for booty and a warlike instinct, urged forward to face perils, and rendered invincible.
The wars we have seen in our days, and of which we deplore the calamities, give nothing but a feeble idea of these gigantic invasions, in which many millions of men perished by sword and famine. China experienced twice all the evils inseparable from a war which appeared to be directed by the genius of destruction; and, in the space of a few years, the most ancient and the most powerful kingdom of Asia, covered with blood and ruins, and deprived of half its population, became one of the provinces of the new empire founded by the shepherds of Mogulistan.
The conquest of Carismia soon followed that of China; Carismia was close to the frontiers of the Mogul empire, and, on one side extended to the Gulf of Persia, and on the other, to the limits of India and Turkistan. Gengis learnt that a Tartar caravan and three of his ambassadors had been massacred in one of the cities of the Carismians. It is easy to imagine the effect that this news would produce upon the emperor of the Moguls, who himself compared the anger of kings to the fire of conflagrations, which the lightest wind may light up.[266] After having fasted and prayed, during three days and three nights, upon a mountain, where a hermit announced to him, the second time, the conquest of the whole world, the terrible Gengiskhan commenced his march, at the head of seven hundred thousand Tartars. This army met that of the Carismians on the banks of the Jaxartes; Mahomet, sultan of Carismia, who had several times carried his victorious arms into Turkistan and Persia, commanded the host of the Carismians. The plain in which this battle was fought was covered by twelve hundred thousand combatants; the shock was terrific, the carnage horrible; victory was adverse to Mahomet, who, from that day, together with his family and the whole of his nation, sunk into the lowest abyss of misfortune.
The cities of Otrar, Bochara, Samarcand, Candahar, and Carismia, besieged by an innumerable multitude, fell in turn into the power of the conqueror, and witnessed the extirpation of their garrisons and inhabitants. We cannot suppress a feeling of pity when history presents to us, on one side, an entire population flying from their devastated homes, to seek an asylum in deserts and mountains; and on the other, the family of a powerful monarch dragged into slavery or groaning in exile; and this monarch himself, whose prosperity all Asia had boasted or envied, abandoned by his subjects, and dying with misery and despair in an island of the Caspian Sea.
The army of Gengiskhan returned to Tartary, loaded with the spoils of Carismia: the sovereign of the Moguls[267] appeared to form the desire of governing his conquests in peace; but the world, agitated by his victories, and always eager to throw off his yoke, together with the warlike spirit of his nation, to whom he had afforded a glimpse of the riches of other people, would not permit him again to enjoy repose; he was on the point of undertaking a third expedition against China, which seemed disposed to rebel, when death put an end to his career. Some historians assert that he was struck dead by thunder, as if Heaven had determined itself to crush the instrument of its wrath;[268] others, much more worthy of belief, inform us that the Tartar hero died in his bed, surrounded by his children, to whom he recommended to preserve union among themselves, that they might achieve the conquest of the world. Octaï, the eldest of his sons, succeeded him in the empire, and, according to the custom of the Moguls, the great men assembled and said to him, “We wish, we pray, we command you to accept of entire power over us.” The new emperor answered by this formula, which contains the whole spirit of the despotic governments of the East: “If you desire that I should be your khan, are you resolved to obey me in everything; to come when I shall call you, to go where I shall send you, and to put to death all those I shall command you to kill?” After they had answered “Yes,” he said to them, “Henceforth my simple word shall serve me as a sword.” Such was the government of the Tartars. Octaï was about to reign over an empire composed of several great empires; his brothers and nephews commanded the innumerable armies that had conquered China and Carismia; they governed in his name in the north, in the south, and the east, kingdoms of which the extent was scarcely known; each of his lieutenants was more powerful than the greatest kings of the earth, and all obeyed him as his slaves. For the first time, perhaps, concord was preserved among conquerors; and this monstrous union effected the ruin of all the nations of Asia: Turkistan, Persia, India, the southern provinces of China, which had escaped the ravages of the first invasion, all that remained of the empire of the Abassides and of that of the Seljoucides—all fell before the arms of the redoubtable posterity of Gengiskhan. Many of the sovereigns whom, in these days of disorder and calamity the chance of war hurled from their thrones, had invoked the succour of the Moguls, and favoured the enterprises of that warlike people against neighbouring or rival powers. Fortune enveloped them all in the same ruin, and oriental history compares them to the three dervises whose indiscreet wishes and prayers reanimated, in the desert, the bones of a lion, who sprang up from the bosom of the sand and devoured them.
The conquest of the richest countries of Asia had inflamed the enthusiasm of the Tartars to such a degree, that it would have been impossible for their leaders to confine them within the limits of their own territories, or bring them back to the peaceful labours of pastoral life. Octaï, whether desirous of obeying the paternal instructions, or whether he felt the necessity of employing the restless and turbulent activity of the Moguls, resolved to turn his arms towards the West. Fifteen hundred thousand shepherds or warriors inscribed their names upon the military register; five hundred thousand of the most robust were selected for the great expedition; the others were to remain in Asia, to maintain the submission of the vanquished nations, and complete the conquests commenced by Gengiskhan. Rejoicings, which lasted forty days, preceded the departure of the Mogul army, and were as a signal of the desolation they were about to spread among the countries of Europe.
In their rapid course, the Tartars crossed the Volga, and penetrated, almost without obstacle, into Muscovy, then a prey to the fury of civil war. The devastation of their country, the conflagrations of Kiow and Moscow, and the disgraceful yoke that so long oppressed these northern regions, were the punishments due to the feeble resistance of the Muscovites. After the conquest of Russia, the multitude of Moguls, led by Batou, son of Tuli, directed their victorious course towards Poland and the frontiers of Germany, and repeated, wherever they went, the horrors of Attila and his Huns. The cities of Lublin and Warsaw disappeared on their passage, and they laid waste both shores of the Baltic. In vain the duke of Silesia, the Polish palatines, and the grand master of the Teutonic order, united their forces to arrest the progress of this new scourge of God;[269] the generous defenders of Europe succumbed upon the plains of Lignitz, and nine sacks, filled with human ears, were the trophy of the victory of the barbarians. The Carpathian mountains presented but a feeble barrier to these invincible hordes; and the Tartars soon burst like a fearful tempest over the territories of those Hungarians who, two centuries before, had, like them, quitted the deserts of Scythia, and conquered the fertile banks of the Danube. Bela, king of Hungary, had recently attracted forty thousand families of Comans into his dominions, who betrayed him; the palatines and magnates of the kingdom were divided among themselves, and not even the aspect of danger could induce them to unite or submit themselves to the laws of the monarch. Disobedience, treachery, and discord, delivered the whole kingdom up to the furies of a pitiless enemy; the flocks, the harvests, the entire wealth of the country, became the prey of the Moguls; half the population was exterminated. Of all the cities of Hungary, only three offered an earnest and true resistance, and thus preserved themselves from scenes of carnage and destruction. The shepherds of Scythia, who could not read, have left to the vanquished the task of describing their conquests, and we have great difficulty in crediting the accounts of the old Hungarian chronicles, when they describe the unheard-of cruelties by which the Moguls disgraced their victories;[270] but several provinces entirely depopulated and changed into deserts, the ruins of two thousand churches, fifty destroyed cities, the traditions of these great disasters transmitted from age to age, and the terror that pervaded Europe, are evidences so worthy of faith, that we cannot reject them.
In the general consternation, it is surprising that the Moguls did not direct their arms against the Latin empire of Constantinople, then menaced by the Greeks, and little better than a ruin; but the shepherds of the desert did not employ themselves in inquiries concerning the interior revolutions of states or of the signs of their decay; they preserved, as did all the nations of Asia, a vague and confused idea of the power of the armies of ancient Byzantium, but took little heed whether the moment were come to attack it and conquer it. The great advantages which the imperial city derived from its position between Europe and Asia, did not at all strike the Tartars, who were ignorant of both navigation and commerce, and infinitely preferred rich pastures to the sumptuous edifices of great capitals. Thus we may equally believe, either that the city of Constantine was protected on this occasion by the memories of its past greatness, or that it owed its safety to the contempt and indifference of the barbarians.
The Franks established in Syria enjoyed the same good fortune as the Greeks of Byzantium. The armies of the Moguls had not yet crossed the Euphrates.
