The Slovenian nobility refers to the social class of nobles in Slovenia, which has roots dating back to the Middle Ages. This class was often associated with land ownership and governance, playing a significant role in the region's political and economic development. Many noble families were granted titles and privileges by the Holy Roman Empire or the Austro-Hungarian Empire. Over time, the influence of the Slovenian nobility diminished, especially after the fall of the Austro-Hungarian Empire in 1918. Today, while some noble titles still exist, they hold little political power, and the nobility is largely a historical and cultural aspect of Slovenia's heritage.
