Controller-General of Finances
Although D'Argenson never held office again, he was reinstated as an honorary Maîtres des Requêtes in 1657. His son Marc-René became Lieutenant General of Police and Controller-General of Finances, two of the most important positions in the Ancien Régime. His grandsons included René Louis d'Argenson, Minister for Foreign Affairs, 1744 to 1747, and Marc-Pierre, Comte d'Argenson, Minister of War, 1743 to 1747.
