The Polish Nobility, known as the szlachta, played a significant role in the history of Poland. This social class emerged in the Middle Ages and was characterized by land ownership and political influence. The szlachta had privileges, such as exemption from certain taxes and the right to participate in the Polish-Lithuanian Commonwealth’s political system, particularly through the Sejm, or parliament. The nobility was diverse, with various ranks and titles, including counts and barons. They were instrumental in shaping Poland's culture, economy, and governance. Over time, the power of the szlachta declined, especially after the partitions of Poland in the late 18th century, which fragmented the nation and diminished noble influence.
