Armand II de Vignerot du Plessis de Richelieu, duke of Aiguillon (31 October 1750 – 4 May 1800) succeeded his father Emmanuel-Armand de Richelieu, duc d'Aiguillon. In 1789, as a member of the National Assembly, he became one of the first to ally himself with the Third Estate and to renounce the privileges of the nobility. He became a general in the Republican Army, but had to flee during the Reign of Terror of 1793–1794.
