Emmanuel Armand de Vignerot du Plessis de Richelieu, Duke of Aiguillon (French pronunciation: [emanɥɛl aʁmɑ̃ viɲʁo dy plɛsi]; 31 July 1720 – 1 September 1788) was a French Royal Army officer and politician. A nephew of Armand de Vignerot du Plessis, until his father's death in 1750 he was known as the Duke of Agénois. He led a regiment in Italy during the War of the Austrian Succession and was seriously wounded at the siege of Château-Dauphin (1744). He was appointed commandant of Brittany in 1753 and defended it against British landing force at Saint-Cast (1758) in the Seven Years' War. He later served as the Secretary of State for Foreign Affairs and briefly as Secretary of State for War under King Louis XV.
