The Nobility of Belgium refers to the hereditary aristocracy in Belgium, which has its roots in the feudal system. The Belgian nobility is recognized by the state and includes various titles such as duke, marquis, count, viscount, and baron. Members of the nobility often have historical ties to the country's governance and land ownership. Belgian nobility is regulated by the Belgian nobility law, which outlines the criteria for titles and their inheritance. While many noble families have significant historical importance, the modern role of the nobility is largely ceremonial, with members often involved in cultural, charitable, and social activities rather than political power.
