Genghis Khan ruled the Mongol Empire in the 13th century, which became the largest contiguous empire in history after his death. Born as Temüjin, he unified the Mongolian steppe tribes, forging a formidable military and expanding the empire across Asia into Europe. Under his leadership, the Mongol Empire facilitated trade, cultural exchange, and communication across vast distances, promoting the Silk Road. Despite its reputation for brutality, Genghis Khan's empire also implemented progressive policies and religious tolerance, profoundly influencing the regions it dominated and shaping the course of history.
