Belgian nobility refers to the hereditary aristocracy in Belgium, which has a long history dating back to the medieval period. The nobility is recognized by the Belgian monarchy and includes various titles such as duke, count, and baron. Members of the nobility often have significant historical estates and play roles in cultural and social events. Today, the Belgian nobility is largely ceremonial, with many nobles involved in business, politics, and philanthropy. The Royal Decree of 1816 established the current system of titles, and while nobility does not confer legal privileges, it remains a symbol of heritage and tradition in Belgian society.
