a French nobleman, the younger son of Henri, Prince of Condé and brother of le Grand Condé and Anne Geneviève, Duchess of Longueville. He played a conspicuous part in the intrigues and fighting of the Fronde, became in 1648 commander-in-chief of the rebel army, and in 1650 was with his brother (Condé) and brother-in-law (Longueville) imprisoned at Vincennes. He took command of the army which in 1654 invaded Catalonia, where he captured three towns from the Spanish. He afterwards led the French forces in Italy, but after his defeat before Alessandria in 1657 retired to Languedoc, where he devoted himself to study and mysticism until his death. Conti also wrote Lettres sur la grâce, and Du devoir des grands et des devoirs des gouverneurs de province.
