He served in the French Army and was one of the foremost diplomats in the service of Louis XV. He is chiefly remembered in connection with the Secret du Roi.[2]


As second son of François-Marie, duc de Broglie, he was accorded the courtesy title of marquis de Ruffec.

After serving as a French military officer, he was seconded to the diplomatic service of King Louis XV. He served as Ambassador Extraordinary to Poland (1752–56), was recalled at the outbreak of the Seven Years' War, was appointed Chevalier des Ordres du Roi (1757), Lieutenant-General (1760), Commandant of Franche-Comté (1761–62), then after the Peace, Governor of Saumurois (1770). He is best remembered in connection with the Secret du Roi, the private—as distinct from the official—diplomatic service of Louis XV,[3] of which he was the ablest and most important member.[2] He held the post of Premier Colonel of Grenadiers.

The Marquis organized the famous Diner de Metz (8 August 1775), when the young Marquis de La Fayette was convinced by the guest of honour, the visiting Duke of Gloucester, brother of King George III, that the insurgents' revolt in America was in some measure justified. Broglie-Ruffec was involved with Beaumarchais in devising a scheme to offer secret support to the American Revolution in its early stages.[4]

His funeral monument is in the Angouleme Cathedral and a portrait of him, painted by Norman-Michel-Hubert Descours in 1762, is at the Château de Bourdeilles.[5]


He married, 21 March 1759, Louise-Augustine de Montmorency (1735–1817); they had three daughters, Louise 1760-1827; Philippine 1762-1843; and Adelaide-Charlotte 1763-1847.[6]
