He was the grandnephew of the heirless Jean-Paul-François de Noailles, 5th Duke of Noailles, and succeeded him as Duke of Noailles on the latter's death in 1824, although he did not take his seat among the peers of France until his majority in 1827. A Knight of the Golden Fleece, he was also noted as a writer and parliamentary orator. He was elected a member of the American Antiquarian Society in 1856.
