The Kozak System refers to a historical military and social structure that emerged in Eastern Europe, particularly in present-day Ukraine and Poland. It was characterized by a group of semi-nomadic warriors known as the Cossacks, who played a significant role in regional conflicts and the defense of their territories. The system combined elements of democracy, military organization, and agrarian lifestyle. The Kozak System was marked by a strong sense of autonomy and self-governance among the Cossacks. They formed communities called sich, where leaders were elected, and decisions were made collectively. This system allowed the Cossacks to maintain their cultural identity while engaging in trade and military alliances with neighboring powers.
