The term "szlachta" refers to the noble class in the historical regions of Poland and Lithuania. This social group emerged in the Middle Ages and played a significant role in the political and cultural life of the Polish-Lithuanian Commonwealth. Members of the szlachta enjoyed various privileges, including land ownership and participation in the Sejm, the legislative assembly. Szlachta was characterized by a strong sense of identity and a commitment to the ideals of liberty and democracy. They were known for their distinctive customs, such as the practice of "liberum veto," which allowed any member to halt legislative proceedings. This unique political system contributed to the complexities of governance in the Commonwealth.
