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, marquises, and counts, often linked to land ownership and political influence. Nobles historically served the monarchy and held privileges, including tax exemptions and special legal rights. Over time, the power of the Spanish nobility has diminished, especially after the Spanish Civil War and the establishment of a constitutional monarchy. Today, while many noble titles still exist, their influence is largely ceremonial, and the nobility has adapted to modern society, participating in cultural and philanthropic activities.
