Czech nobility refers to the social class of aristocrats in the Czech Republic, historically influential in politics, culture, and land ownership. This class emerged in the Middle Ages, with noble families often holding significant power and privileges granted by monarchs. They played a crucial role in the governance and development of the region. Over time, the status of the Czech nobility changed, especially after events like the Austro-Hungarian Empire and the Czechoslovak Republic formation. Many noble estates were confiscated or diminished in power, but some families still exist today, preserving their heritage and contributing to modern Czech society.
