Definition
Genghis Khan was the founder and first ruler of the Mongol Empire. Born around 1162 CE with the name Temujin, he rose from a hard and uncertain childhood to unite the rival nomadic tribes of the Mongolian steppe.
In 1206 CE a council of Mongol leaders proclaimed him Genghis Khan, a title meaning something like universal or fierce ruler. Under his command, the Mongols began the conquests that would build the largest contiguous empire the world has known.
Why it matters
How it works
Genghis Khan's success rested on organization as much as conquest. By restructuring his followers into standardized military units and rewarding loyalty and merit over birth, he created an army that was unusually cohesive and adaptable.
He also valued useful knowledge from the peoples he defeated, adopting siege techniques, recruiting administrators, and protecting merchants and craftsmen. After his death in 1227 CE, his sons and grandsons continued the expansion, though the empire eventually divided among his descendants.
