The Association Royale des Descendants des Lignages de Bruxelles (French) (Dutch": Koninklijke Vereniging der Afstammelingen van de Brusselse Geslachten;" lit. 'Royal Association of the Descendants of the Lineages of Brussels') is a hereditary organization of individuals who have documented their descent from at least one member of the Seven Noble Houses of Brussels.
History.
Like the nobility, the Seven Noble Houses (or lineages) of Brussels were abolished during the French occupation. But whereas the nobility was officially recognised after the Belgian revolution of 1830, the lineages of Brussels were not. The "Association" was founded in 1961 as an asbl (non-profit) with the aim of bringing the descendants of the Seven Noble Houses together.
Activities.
The descendants of the Seven Noble Houses are currently united within this organization which perpetuates their existence and their rituals dating back to the Middle Ages. For example, every year, the organisation takes an active part in the organization of the Ommegang.
Publications.
The organization's main publications are:
Post-nominal letters.
People officially admitted to the "Association" are entitled to use the following post-nominal letters: PB (Patricius Bruxellensis) for all members and NPB (Nobilis Patricius Bruxellensis) in case they are members of the Belgian nobility.
