The title derives its name from Conty, a small town in northern France, c. 35 km southwest of Amiens, which came into the Bourbon-Condé family by the marriage of Louis de Bourbon, first Prince of Condé, with Eleanor de Roye in 1551.He died in 1614 and the title lapsed, since his only child had predeceased him in 1610.In 1629, the title of Prince of Conti was revived in favor of Armand de Bourbon (1629–1666), second son of Henry II, Prince of Condé, and brother of Louis, the Grand Condé.During the time that the House of Bourbon ruled France, from the reign of King Henry IV of France to the reign of King Louis-Philippe of the French, the Princes of Conti were considered to be princes du sang in the Kingdom of France.The holders of this title used the style of Serene Highness.
