Genghis Khan is recognized as the founder of the Mongol Empire, which became the largest contiguous empire in history after his death in 1227. Originally named Temüjin, he united the disparate Mongol tribes and initiated a series of military campaigns that conquered vast territories across Asia and into Europe. His innovative strategies, meritocratic leadership, and adaptability played crucial roles in establishing the Mongol Empire as a formidable force, influencing trade and cultural exchange along the Silk Road.
