Genghis Khan ruled over Mongolia and established the Mongol Empire during the 13th century. Born as Temujin around 1162, he unified the Mongolian tribes and embarked on a series of military campaigns that created the largest contiguous empire in history. Under his leadership, from 1206 onwards, the empire expanded across Asia and into Eastern Europe through conquests and alliances. Genghis Khan’s contributions to governance, law, and trade transformed the regions under his control, promoting cultural exchanges and connections between diverse peoples. His legacy endures in the history of Mongolia and in concepts of leadership and military strategy.
