The Guilds of Brussels (French: Guildes de Bruxelles; Dutch: Gilden van Brussel), grouped in the Nine Nations of Brussels (French: Neuf Nations de Bruxelles; Dutch: Negen Naties van Brussel), were associations of craft guilds that dominated the economic life of Brussels in the late medieval and early modern periods. From 1421 onwards, they were represented in the city government alongside the patrician lineages of the Seven Noble Houses of Brussels,[1] later also in the States of Brabant as members of the Third Estate. As of 1421, they were also able to become members of the Drapery Court of Brussels. Together with the Seven Noble Houses, they formed the city's bourgeoisie. Some of their guildhouses can still be seen as part of the Grand-Place/Grote Markt (Brussels' main square), a UNESCO World Heritage Site.
