A bourgeois of Paris was traditionally a member of one of the corporations or guilds that existed under the Ancien Régime. According to Article 173 of the Custom of Paris, a bourgeois had to possess a domicile in Paris as a tenant or owner for at least a year and a day. This qualification was also required for public offices such as provost of the merchants, alderman or consul, but unlike the bourgeois or citizens of other free cities, Parisians did not need letters of bourgeoisie to prove their status.
