The Nobility of Spain refers to the social class of individuals who hold hereditary titles and privileges. This class has a long history, dating back to the Middle Ages, when noble families played significant roles in politics, military, and land ownership. Nobility in Spain is often associated with titles such as duke, marquis, count, and baron, which can be inherited or granted by the monarchy. Today, the Spanish nobility is largely ceremonial, with many noble families maintaining their titles without significant political power. The Spanish Constitution of 1978 recognized the nobility but emphasized equality among citizens. Nobles often participate in cultural and charitable activities, preserving their historical legacy.
