Rohan, Henri, duc de (äNrēˈ dük də rôäNˈ) [key], 1579–1638, French Protestant general; son-in-law of the duc de Sully. A leader of the Huguenots, Rohan took up arms against the French government in 1621–22 as a consequence of the reestablishment of Roman Catholicism in Béarn. With his brother, Benjamin de Soubise, Rohan led revolts in Languedoc and the Cévennes in 1625–26 and again in 1627–29 but was forced to submit to King Louis XIII's chief minister, Cardinal Richelieu, in the Peace of Alais (1629). He retired to Venice. In 1635 he was chosen by Richelieu to command the French troops in the Valtellina, which he subdued. Treachery and weak official support forced his retreat in 1637. Rohan subsequently joined the army of Bernhard of Saxe-Weimar and was killed at Rheinfelden during the Thirty Years War. He left memoirs (1644, enl. ed. 1646, tr. 1660) and other writings.
