TheRise ofGenghis Khan involves the events from his birth as Temüjin in 1162 until 1206, when he was bestowed the title of "Genghis Khan" (sometimes "Chingis Khan"), which means "Universal Ruler" or "Oceanic Ruler" by theQuriltai, which was an assembly of Mongol chieftains.

TheMongols first appeared in the dynastic history of theTang dynasty and were described as a branch of theShiwei, who were vassals of theGöktürks from 553 to 745. The Shiwei lived in theLesser Khingan Range until the 10th century when the Mongol component moved to theArgun River and became vassals of the Khitans. The Mongols continued moving west until they reached theOnon River andKherlen River in the 11th century.^[1]

Alternatively according to Mongol mythology, they were descended from a blue-grey wolf birthed by Heaven, and a fallow doe. Together they crossed a lake to reachBurkhan Khaldun where they gave birth to a human male. This human male, named Bat Tsagan, was the ancestor of all Mongols. In the 11th generation of Bat Tsagan's lineage, Dobun Mergen married a young woman named Alan Gho'a of the Khorilar. After Dobun Mergen died, Alan Gho'a gave birth toBodonchar Munkhag, who founded theBorjigin clan.^[2]

Bodonchar's great-great-grandsonKaidu was born sometime during the 11th century and was the firstkhagan who "ruled all the Mongols".^[3] His grandsonKhabul Khan was invited to theJin court at one point and in a drunken outburst, tweaked the Jin emperor's beard. The emperor initially decided to let Khabul go unpunished but changed his mind and ordered his officials to have Khabul captured. The Jin pursuers were ambushed and killed, and Kaidu died shortly after, depriving the Jin any chance of revenge. Chinese sources make no mention of this incident.^[4][5]

From 1135 to 1147, the Mongols continuously raided Jin borders. The Jin retaliated and allied with theTatars, who captured the new Mongol khan,Ambaghai of theTaichiud, under the pretense of making peace and handed him over to the Jin court. Before he was captured, Ambaghai managed to send a messenger back to his kinsmen, urging them to fight the Tatars to the death.^[5] Ambaghai was nailed to a wooden donkey and left to die. Around the time of Ambaghai's capture in the 1150s or 1160s, Khabul's grandsonYesugei abducted aKhongirad woman as his bride from theMerkits. He participated in a series of raids launched byHotula Khan against the Tatars. Upon his return from one of these attacks, his wife gave birth to Temüjin, who would become Genghis Khan.^[6]

TheMengda Beilu records that the Mongols developed a profound hatred of the Jin because of massacres and atrocities that they committed in the late twelfth century. Whether these stories were real memories or a form of propaganda being used against the Jin is difficult to ascertain. Chinggis Khan certainly tried to unite other tribes to his cause by evoking their shared hatred of the Jin. On meeting the Khitan prince, Yelü Chucai, for instance, Chinggis Khan claimed that his war against the Jin was vengeance for their actions against the Khitan people.^[7]

The year of Temüjin's birth is disputed and multiple dates are given by different historians: 1155, 1162 or 1167.^[8][9] However 1162 is the most accepted date.^[10] It is possible that Temüjin never knew the exact date of his birth.^[11] TheSecret History records his birthplace asDelüün Boldog on theOnon River, but this has been placed at eitherDadal inKhentii Province or in southernAgin-Buryat Okrug, Russia.^[12]

Genghis Khan was born as Temüjin to Yesugei, the leader of theBorjigin clan, andHoelun of theOlkhonud tribe. In 1171, Yesugei took Temüjin east through Tatar territory to the Khongirad, who were closely related to the Olkhonud tribe of his wife, to arrange a future marriage between his son andBörte. Temüjin was left behind with the Khongirad to learn their ways, however Yesugei was poisoned by the Tatars during his return trip. Yesugei sent a trusted retainer called Münglig to retrieve Temüjin from the Khongirad, but he arrived too late to see his father alive.^[13] His father's followers scattered and Hoelun was left to care for her children by herself.^[14] She took them to theKhentii Mountains where they lived for several years eking out an existence through fishing and grubbing roots.^[15] Little is known about the events of Temüjin's life during these years except for three flashpoints. At one point Temüjin killed his half-brother Begter for stealing a fish. He then became the captive of theTaichiud and lived in a cage for some time before escaping with the help of a tribesman named Suldus Shira.^[16] In 1173, he became the blood brother (anda) ofJamukha from the Jadaran (Jajirad) clan. The Jadaran clan considered itself descended from the Borjigids, but others say they were an illegitimate offshoot of uncertain birth.^[17]

In 1177, Temüjin went back to the Khongirad and marriedBörte, but she was kidnapped shortly thereafter in aMerkit raid. Temüjin gathered 20,000 warriors and enlisted the help of his blood brothersJamukha andToghrul, the khan of theKeraites. Together they helped Temüjin get backBörte. It's not clear how she was returned or whether a military action was involved in the process. One version of events claim the combined forces routed theMerkit and she was rescued along with much booty, but this could have been a composite narrative combining a later military action with an earlier event.Börte gave birth soon afterwards and although the child may have been fathered by aMerkit, Temüjin decided to raise him as his own anyway, naming himJochi.^[18]

The period of Temüjin's life from 1177 to 1191 is largely unknown except that Temüjin often fought the Taichiud, Salji'ut, Khadagin, andTatars with mixed results. One of the clans following Temüjin eventually left and was defeated by the Taichiud, after which they joinedJamukha.^[18] During the 1180s there was a drought inMongolia which increased conflict between the tribes but Temüjin only played a limited part in these affairs.^[19]

The previous attack on theMerkit that resulted in the rescue ofBörte may have been a separate campaign that occurred in 1191, and was confused in the sources. In 1191,Jamukha, Temüjin, andToghrul and his brother Jakha Gambhu decided to attack theMerkit. However Temüjin andToghrul were late to the rendezvous area by three days, which greatly angeredJamukha. Together the 40,000 strong allied forces made a detour east to attack the enemy camp from the north-east. A fisherman spotted them and warned theMerkit of the impending attack, but theMerkit failed to make the necessary preparations, and dispersed.^[20]

Temüjin andJamukha stayed together for a while after the battle. At one point they sent an embassy to the Khadagin and Salji'ut to try to win them over against the Taichiud. In 1187 or 1193, Temüjin andJamukha split when retainers of the two camps clashed over horse thievery. Temüjin took with him 41 tribal leaders and 10,000 men fromJamukha and was elected khan by his followers in the following days. The Taichiud became frightened by Temüjin's power and joinedJamukha.^[21][22]

Jamukha assembled 30,000 men and moved in an arc from the north to flank Temüjin's position. The two forces were evenly matched but Temüjin's side suffered slightly worse thanJamukha, and was forced to retreat to a defensible pass called Jerene near theOnon River. Despite Jamukha's victory, his harsh treatment of captives disgusted his allies so much that they defected to Temüjin, bringing with them 10,000 men. With less than 20,000 men at his side,Jamukha was no longer able to challenge Temüjin on the upperKherlen River, and retreated further east.^[23][22]

Modern historians such as Ratchnevsky and Timothy May consider it very likely that Temüjin spent a large portion of the decade following the clash at Dalan Baljut as a servant of the JurchenJin dynasty inNorth China.^[24] Zhao Hong recorded that the future Genghis Khan spent several years as a slave of the Jin. Formerly seen as an expression of nationalistic arrogance, the statement is now thought to be based in fact, especially as no other source convincingly explains Temüjin's activities between Dalan Baljut andc. 1195.[25] Taking refuge across the border was a common practice both for disaffected steppe leaders and disgraced Chinese officials. Temüjin's reemergence having retained significant power indicates that he probably profited in the service of the Jin. As he would later go on to overthrow that state, such an episode, detrimental to Mongol prestige, was omitted from all their sources. Zhao Hong was bound by no such taboos.^[26]

In 1195, theJurchen Jin dynasty allied with theTatars to attack the Khongirad. The resulting military operation was a success but theTatar leader, Zuxu, quarrelled over the distribution of loot. Breakdown of communication led to aJin attack on theTatars in the following year. TheJin general Wanyan Xiang sent a vanguard detachment under Wanyan Anguo toward theKherlen River, where they held offTatar forces for three days before the main body of theJin army arrived and defeated them.^[27]

The Khongirad had not forgotten their previous conflicts. On 4 February 1196, they struck deep intoJin territory and defeated aJin detachment. Meanwhile, theTatars fleeingJin forces were intercepted byToghrul and Temüjin. The beleagueredTatars chose to fight in a makeshift barricade instead of on the open field, probably because they were much weaker than the opposing force. The resulting melee resulted in the complete defeat of theTatars.Toghrul and Temüjin later met withJin officials, who were extremely pleased with the destruction of theTatars, and awarded them with titles. One of the Jin officials, aKhitan by the name of Yelü Ahai, was so impressed with Temüjin, that he and his brother Tuhua later defected to him in 1203.^[28]

Soon after the defeat of theTatars,Toghrul was overthrown by his brother Erke Qara, who was backed byInanch Bilge khan of theNaimans. ANaiman force enteredKeraite territory and attacked Temüjin's camp, causing some damage.Toghrul fled to theQara Khitai.^[28]

The defeatedTatar Zuxu submitted to theJin and rebelled again in the same year. Zuxu submitted to theJin again in 1198 and died soon afterward. Wanyan Xiang ordered the construction of extensive defensive works to protect sedentary population in the north. No furtherJin campaigns against the steppe nomads were carried out with the same success as that of 1196.^[29]

Threatened by theNaimans' increasing influence, Temüjin sought help from the Jurkins to conduct a joint expedition against theNaimans. The Jurkins responded by killing Temüjin's envoys. Temüjin attacked them in 1196 and subjugated the majority of the Jurkins, includingMuqali, who would later become one of theMongol Empire's foremost generals.Toghrul's brother Erke Qara also joined Temüjin after he helped him drive off theMerkit. In 1197,Toghrul returned and re-established himself as leader of theKeraites with the help of Temüjin. In the winter of 1197–8, Temüjin eliminated the remaining Jurkins and executed their leaders.^[30]

From 1198 to 1199, Temüjin andToghrul preyed on theMerkit, driving them ever further north.Toghrul chose not to share the booty with Temüjin, which upset him greatly.^[31]

Inanch Bilge khan died in 1198, splitting theNaimans between his two sonsTayang khan andBuyruq khan. In 1199, Temüjin,Toghrul, andJamukha attackedBuyruq west of theAltai Mountains. Alarmed by the eastern invaders,Tayang sent a force under Kökse Sabraq, which intercepted Toghrul and took half his people hostage. Temüjin sent Muqali,Borokhula, Chilaun, andBo'orchu to support the Keraites. They arrived in time to turn the tide of battle and routed theNaimans. Despite the victory in battle, the allied forces moved further east, possibly out of fear that the two Naiman factions might recoup and unite against them.^[32]

In 1200, Temüjin andToghrul migrated eastwards along the Onon River into Taichiud territory and defeated the Taichiud in battle. Temüjin chased the fleeing Taichiud to a river crossing where he was surprised by a sudden counterattack that wounded him. The battle continued the next day until the Taichiud had been defeated. Next, the Khadagin, Salji'ut, Dorben, Tatar, and Khongirad tribes formed a coalition against Temüjin. The two sides engaged in a heavily contested battle that ended in retreat forToghrul and Temüjin.^[33]

WhileToghrul was incapacitated for two years, Temüjin recovered his losses and returned to wage war on theTatars and Dorben while his brotherQasar attacked the Khongirad. Temüjin's enemies, especially, the Khongirad, then gathered aroundJamukha and named himgur-khan in opposition to Temüjin. Jamukha's forces suffered a defeat against Temüjin in 1201, resulting in a brief defection by the Khongirad before they returned to fighting Temüjin the next year.^[34]

In 1202, Temüjin introduced new rules for distributing plunder. Several of his relatives disagreed with the new way of distribution and left with 10,000 men. In the same year Temüjin finished mopping up theTatars. He intended to have all the Tatar captives executed, probably in revenge for his father, but his half-brother Belgutai leaked the information to the prisoners, who broke away and barricaded themselves on a hill. Temüjin's brotherQasar, whose wife wasTatar, also hid 500 captives who were supposed to be killed.^[35]

Buyruq khan assembled a large coalition army including evenJamukha and theOirats numbering 70,000 strong. Together they advanced on Temüjin and Toghrul's position atBuir Lake. Temüjin andToghrul moved their forces behind theJin defensive fortifications. Both sides' forces were scattered and the weather took a turn for the worse with heavy snows and wind blasting the battlefield.Buryuq decided to retreat but got stuck in an open field at one point. The coalition army fell into confusion.Jamukha took the opportunity to plunder his allies' baggage. This came to be known as theBattle of Köyiten.^[36]

Toghrul's son Senggüm convinced his father to turn on Temüjin. They planned to ambush him while he was on his way to a wedding between the two families to cement their alliance, but a Keraite warned Temüjin beforehand and spoiled their plan. A battle ensued with Toghrul and Jamukha taking the offensive by attacking Qasar and defeating his army. Qasar escaped but most of his family was captured. Next they advanced on Temüjin, surprising him from the south, but Temüjin managed to move to a smaller enclosure to nullify the enemy's superior numbers. Senggüm was wounded in battle, throwing his forces into confusion, and allowing Temüjin to retreat. Toghrul decided not to give chase and returned to camp. This came to be known as theBattle of Qalaqaljit Sands.^[37][38] After this heavy defeat, Temüjin and the leaders of his remaining followers –a socially, culturally, and religiouslyheterogeneous mixture of people– swore an oath of brotherhood which became known as theBaljuna Covenant.^[39]

Meanwhile, Jamukha and a large portion of Toghrul's allies decided to split from him. When Toghrul caught wind of this, he attacked them, and some of them defected to Temüjin. By autumn of 1203, the situation between the two sides had been reversed, Temüjin's forces numbered more than 40,000 while Toghrul had barely half of that. Temüjin scouted out Toghrul's camp under false pretenses of defection by Qasar. When Toghrul's location had been ascertained, Temüjin's army rode through the night and surrounded the Keraite camp. The Keraites fought for three days before they surrendered. Toghrul fled the battle only to be killed by a Naiman called Qori Sübeči who did not believe his identity. Senggüm fled toWestern Xia.^[40]

Jamukha, the Merkits, and Keraites joined Tayang khan's Naimans in opposing Temüjin. By this time, Temüjin had 66,000 fighting men and moved most of them west in May 1204 to confront Tayang in what became theBattle of Chakirmaut. Supposedly Naiman scouts were unimpressed with the quality of Temüjin's troops, but Tayang wanted to retreat beyond the Altai Mountains to fight a war of attrition. Tayang's sonKuchlug as well as his senior officer argued against it and convinced Tayang to take the offensive against Temüjin. The opposition coalition forces crossed theOrkhon River but fell back to the foot of a mountain upon encountering Temüjin's forces. Temüjin ordered his army to stand in "lake" battle formation and to fight a "chisel" battle. His army dispersed in a long line as if to outflank the Naimans, which the Naimans responded by dispersing their own forces as well. Having deceived the Naimans into believing that he was going for a flanking maneuver, Temüjin led a frontal assault followed by the main army led by Qasar, driving the Naimans back to a mountain. Jamukha deserted the Naimans, who rejected Temüjin's offer of surrender and fought for another day until they were all killed. Tayang fell in battle.^[41]

Kuchlug had been left to defend a rear camp. When Temüjin's army came upon him, Kuchlug fled with a few followers. Jamukha was caught soon afterward, delivered to Temüjin, and executed.^[41]

Toqtoa's Merkits fled southwest ofKhovd and moved even further west when Temüjin moved against him. Toqtoa and Kuchlug joined Buyruq khan west of the Altai. The Uvas Merkits tried to defect to Temüjin, but Temüjin considered them too weak to be of use and did not want to integrate them, so they rebelled and took some supplies with them. The other Merkits either surrendered or were killed by 1205. One of the captured wasTöregene, who marriedÖgedei. She became regent of the Mongol Empire when her husband died in 1241.^[42]

In April 1205, Temüjin made his first major incursion on a non-Mongol power, the Western Xia. The Khitan, Yelü Ahai, who defected to Temüjin some years ago led the way, ostensibly in search for Senggum, Toghrul's son. The Xia armies dared not fight the Mongols on the open field and made no move against them. The Mongols moved unopposed, plundering the open country, and destroying a few fortifications. After they left in June, the Xia rebuilt the places destroyed. In December a counter-raid was organized by the Xia but ultimately no attack was made. Soon after Senggum was killed in battle.^[43]

In the summer of 1206, the shaman Kokochu proclaimed TemüjinGenghis Khan (Chinggis Khan), the "Universal Ruler", at the Onon River. Genghis reorganized Mongol society into a military force based on units of a thousand known asmingghan. These were not only military units but also household units and used for taxation purposes. His family members, thealtan urugh or Golden Kin, were given territory and assigned these mingghan. A 10,000 strong bodyguard unit known as thekeshig was formed from the sons of commanders to ensure their loyalty to Genghis.^[44]

In the winter, Genghis ambushed Buyruq while he was out hawking and killed him. Toqtoa and Kuchlug fled up along theErdis River.^[45] In 1207, Genghis sent his sonJochi to subdue theOirats andKyrgyz people west ofLake Baikal. They submitted voluntarily, adding 20,000 warriors to the Mongol army.^[46]
