Around 1162, on the wind-scoured Mongolian steppe, a child named Temüjin was born to Yesugei, a minor chieftain of the Borjigin clan, and his wife Hö'elün. When Temüjin was only eight, his father died, and the tribe abandoned the widow and her children to fend for themselves. Reduced to near-poverty, Temüjin's early life was marked by desperation so severe that he killed his older half-brother Behter to secure his place within the family.

Out of this hardship, a fierce charisma emerged. Temüjin attracted early followers and forged alliances with two powerful steppe leaders, Jamukha and Toghrul, working alongside them to rescue his newlywed wife Börte after she was kidnapped by raiders. But success bred rivalry: his bond with Jamukha curdled into open warfare, and around 1187 Temüjin suffered a crushing defeat at Jamukha's hands. He may have spent the following years living under the shadow of the Jin dynasty before resurfacing in 1196 to rapidly rebuild his power.

Toghrul, once an ally, came to see Temüjin as a threat, and in 1203 it was Toghrul who struck first with a surprise attack. Temüjin regrouped, overpowered him, then crushed the Naiman tribe and executed Jamukha, emerging as the undisputed ruler of the Mongolian steppe. In 1206, at a great assembly, he formally took the title Genghis Khan — a name whose exact meaning remains debated to this day.

Genghis moved quickly to reshape Mongol society, dismantling old tribal loyalties and replacing them with an integrated system built on merit and loyalty to the ruling family. Having thwarted a coup attempt led by a powerful shaman as he consolidated his rule, he began turning his attention outward. In 1209 he raided the neighboring Western Xia kingdom, which submitted to Mongol terms within a year. He then launched a four-year campaign against the Jin dynasty, capturing their capital, Zhongdu, in 1215.
