Duke of Saint-Simon


Duke of Saint-Simon was a title of French nobility in the Peerage of France that was granted in 1635 to Claude de Rouvroy, comte de Rasse. The title's name refers to the seigneury that was held by the Rouvroy family at Saint-Simon in Aisne.
The dukedom passed from father to son in 1693. The second and last holder of the title, Louis de Rouvroy, has been immortalized as one of the greatest memoirists in European history.
The second duke's two sons both predeceased him, making the French dukedom extinct in 1755. However, the second duke had been given a Spanish dukedom when he was ambassador there, which could be inherited through the female line, and descendants continued to use this title until the 19th century.
