The historical figure who founded the Ottoman Empire in the 13th century was Osman I. Known for his leadership and military prowess, Osman began consolidating power in northwestern Anatolia around 1299. His establishment of a small but cohesive state laid the groundwork for what would become a vast and powerful empire. The name "Ottoman" derives from Osman’s name, and he is often credited with fostering the early structures of governance, military organization, and cultural identity that would define the Empire throughout its expansion, dramatically influencing Eurasian history.
