The Zaporizhian Cossacks were a group of semi-nomadic warriors and settlers who emerged in the 15th century in the region around the Dnieper River in present-day Ukraine. They formed a unique society known for its democratic governance, military prowess, and distinct cultural traditions. The Cossacks played a significant role in the history of Eastern Europe, often acting as a buffer between the Polish-Lithuanian Commonwealth and the Ottoman Empire. The Zaporizhian Cossacks established the Zaporizhian Sich, a fortified settlement that served as their military and administrative center. They were known for their fierce independence and resistance against foreign domination, particularly during conflicts with the Russian Empire. Their legacy continues to influence Ukrainian culture and identity today.
