The term "noblesse d'épée" refers to a class of French nobility that emerged during the Middle Ages, characterized by their military roles and responsibilities. Members of this class were often landowners who held titles and were expected to serve as knights, defending their territories and the king. Their status was linked to their martial prowess and loyalty to the crown. In contrast to the "noblesse de robe," who gained their status through legal or administrative roles, the noblesse d'épée emphasized honor and valor in battle. This distinction played a significant role in the social hierarchy of France and influenced the dynamics of power during the Ancien Régime.
