The Spanish Nobility refers to the hereditary aristocracy in Spain, which has played a significant role in the country's history. This class includes various titles such as dukes, marquesses, counts, and barons, often linked to land ownership and political influence. Nobility in Spain has roots dating back to the Middle Ages, with many families tracing their lineage to the Reconquista. Spanish nobles historically held privileges, including tax exemptions and political power. The Spanish Constitution of 1812 and subsequent reforms reduced their influence, but many noble families still exist today, maintaining their titles and participating in cultural and social events.
