Genghis Khan - Rise To Power - Encyclopedia Britannica

With powerful allies and a force of his own, Temüjin routed the Merkit, with the help of a strategy by which Temüjin was regularly to scotch the seeds of future rebellion. He tried never to leave an enemy in his rear; years later, before attacking China, he would first make sure that no nomad leader survived to stab him in the back. Not long after the destruction of the Merkit, he treated the nobility of the Jürkin clan in the same way. These princes, supposedly his allies, had profited by his absence on a raid against the Tatars to plunder his property. Temüjin exterminated the clan nobility and took the common people as his own soldiery and servants. When his power had grown sufficiently for him to risk a final showdown with the formidable Tatars, he first defeated them in battle and then slaughtered all those taller than the height of a cart axle. Presumably the children could be expected to grow up ignorant of their past identity and to become loyal followers of the Mongols. When the alliance with Toghril of the Kereit at last broke down and Temüjin had to dispose of this obstacle to supreme power, he dispersed the Kereit people among the Mongols as servants and troops. This ruthlessness was not mere wanton cruelty. Temüjin intended to leave alive none of the old, rival aristocrats, who might prove a focus of resistance; to provide himself with a fighting force; and, above all, to crush the sense of clan loyalties that favoured fragmentation and to unite all the nomads in personal obedience to his family. And when, in 1206, he was accepted as emperor of all the steppe people, he was to distribute thousands of families to the custody of his own relatives and companions, replacing the existing pattern of tribes and clans by something closer to a feudal structure.

At least from the time of the defeat of the Merkits, Temüjin was aiming at supremacy in the steppes for himself. The renewed friendship with Jamuka lasted only a year and a half. Then, one day while the two friends were on the march, Jamuka uttered an enigmatic remark about the choice of camping site, which provoked Temüjin’s wife Börte to advise him that it was high time for the two friends to go their separate ways. What lies behind this episode is difficult to see. The story in the Secret History is too puzzling in its brevity and its allusive language to permit a reliable explanation. It has been suggested that Jamuka was trying to provoke a crisis in the leadership. Equally, it may be that the language is deliberately obscure to gloss over the fact that Temüjin was about to desert his comrade. In any event, Temüjin took Börte’s advice. Many of Jamuka’s own men also abandoned him, probably seeing in Temüjin the man they thought more likely to win in the end. The Secret History justifies their action in epic terms. One of the men tells Temüjin of a vision that had appeared to him and that could only be interpreted as meaning that Heaven and Earth had agreed that Temüjin should be lord of the empire. Looking at the situation in a more down-to-earth way, the interplay of the vacillating loyalties of the steppe may be discerned. The clansmen knew what was afoot, and some of them hastened to move over to Temüjin’s side, realizing that a strong leader was in the offing and that it would be prudent to declare for him early on.

The break with Jamuka brought about a polarization within the Mongol world that was to be resolved only with the disappearance of one or the other of the rivals. Jamuka has no advocate in history. The Secret History has much to tell about him, not always unsympathetically, but it is essentially the chronicle of Temüjin’s family; and Jamuka appears as the enemy, albeit sometimes a reluctant one. He is an enigma, a man of sufficient force of personality to lead a rival coalition of princes and to get himself elected gur-khān, or supreme khan, by them. Yet he was an intriguer, a man to take the short view, ready to desert his friends, even turn on them, for the sake of a quick profit. But for Temüjin, it might have been within Jamuka’s power to dominate the Mongols, but Temüjin was incomparably the greater man; and the rivalry broke Jamuka.

Clan leaders began to group themselves around Temüjin and Jamuka, and, a few years before the turn of the century, some of them proposed to make Temüjin khan of the Mongols. The terms in which they did so, promising him loyalty in war and the hunt, suggest that all they were looking for was a reliable general, certainly not the overlord he was to become. Indeed, later on, some of them were to desert him. Even at this time, Temüjin was only a minor chieftain, as is shown by the next important event narrated by the Secret History, a brawl at a feast, provoked by his nominal allies the Jürkin princes, whom he later massacred. The Jin emperor in northern China, too, looked on him as of no great consequence. In one of the reversals of policy characteristic of their manipulation of the nomads, the Jin attacked their onetime allies the Tatars. Together with Toghril, Temüjin seized the opportunity of continuing the clan feud and took the Tatars in the rear. The Jin emperor rewarded Toghril with the Chinese title of wang, or prince, and gave Temüjin an even less exalted one. And, indeed, for the next few years the Jin had nothing to fear from Temüjin. He was fully occupied in building up his power in the steppe and posed no obvious threat to China.

Temüjin now set about systematically eliminating all rivals. Successive coalitions formed by Jamuka were defeated. The Tatars were exterminated. Toghril allowed himself to be maneuvered by Jamuka’s intrigues and by his own son’s ambitions and suspicions into outright war against Temüjin, and he and his Kereit people were destroyed. Finally, in the west, the Naiman ruler, fearful of the rising power of the Mongols, tried to form yet another coalition, with the participation of Jamuka, but was utterly defeated and lost his kingdom. Jamuka, inconstant as ever, deserted the Naiman khan at the last moment. These campaigns took place in the few years before 1206 and left Temüjin master of the steppes. In that year a great assembly was held by the River Onon, and Temüjin was proclaimed Genghis Khan: the title probably meant Universal Ruler.
