Under the Ancien Régime of France, the Nobles of the Robe or Nobles of the Gown (noblesse de robe) were French aristocrats whose rank came from holding certain judicial or administrative posts. As a rule, the positions did not of themselves give the holder a title of nobility, such as baron or viscount (although the holder might also have such a title), but they were almost always attached to a specific function. The offices were often hereditary, and by 1789, most of the holders had inherited their positions. The most influential of them were the 1,100 members of the 13 parlements, or courts of appeal. They were distinct from the "Nobles of the Sword" (noblesse d'épée), whose nobility was based on their families' traditional function as the knightly class and whose titles were usually attached to a particular feudal fiefdom, a landed estate held in return for military service. Together with the older nobility, the Nobles of the Robe made up the Second Estate in pre-revolutionary France. Because these noblemen, especially the judges, had often studied at a university, they were called Nobles of the Robe after the robes or gowns that scholars wore, especially at commencement ceremonies. Originally given out as rewards for services to the king, the offices became venal, a commodity to be bought and sold (under certain conditions of aptitude). This practice became official with the edict of la Paulette, the Paulette being the tax paid by the holder to keep the office hereditary. As hereditary offices, they were often passed from father to son. Nobles of the Robe were often considered by Nobles of the Sword to be of inferior rank, because their status was not derived from military service and/or land ownership. The elite Nobles of the Robe, such as members of the parlements, fought to preserve their status alongside the Nobles of the Sword in pre-revolutionary French society. Originally, the offices within the Nobles of the Robe were relatively accessible due to their venal nature.
