A Khan is a title of nobility and leadership in various Central Asian cultures, particularly among the Mongols and Turkic peoples. Historically, Khans were rulers of tribes or regions, often leading their people in warfare and governance. The title signifies authority and respect, and it has been used by many prominent leaders throughout history. One of the most famous Khans is Genghis Khan, who united the Mongol tribes in the early 13th century and established one of the largest empires in history. His leadership style emphasized meritocracy and loyalty, which helped him expand his empire across Asia and into Europe.
