French branch of the House of Bourbon .
The title of prince of Conti, created in the 16th century, was revived in favor of Armand de Bourbon, prince de Conti (1629–1666), who was a leader in the Fronde. He was the younger brother and rival of the prince de Condé ("the Great Conde"). Notable members of the Conti family include François-Louis de Bourbon, prince de Conti (1664–1709), who was a candidate for the Polish throne; and Louis-François de Bourbon, prince de Conti (1717–1776), who served in the War of the Austrian Succession . The House of Conti became extinct with the death of Louis-François-Joseph de Bourbon, prince de Conti (1734–1814), who had distinguished himself in the Seven Years' War.
