Philippe-Louis-Marc-Antoine de Noailles, 1st duc de Mouchy

Philippe-Louis-Marc-Antoine, comte de Noailles, prince-duc de Poix, and 2nd Spanish and 1st French duc de Mouchy (21 November or 21 December 1752 — 17 February 1819), was a French soldier, and politician of the Revolution.

The son of Philippe de Noailles and grandson of Adrien-Maurice, 3rd duc de Noailles, he was born on 21 November 1752 and held the courtesy title of prince de Poix as a child.

In 1789 he was elected to the Estates-General by the noblesse of Amiens and Ham, but was compelled to resign in consequence of a duel with the commander of the National Guard of Versailles.

He left the country for some time, but returned to France and took part in the riots of August, 1792. He was, however, forced to quit the country once more to evade the fate of his father and mother, guillotined in 1794. On his father's death, he acceded à brevêt to the titles of comte de Noailles and duc de Poix, as well as to the Spanish title duc de Mouchy.

Returning to France in 1800, with the amnesty of Émigrés, he lived quietly at his residence in Mouchy-le-Châtel (Oise) during the Empire. After the Bourbon Restoration, he again came into favor and in 1817 was created duc de Mouchy as a French title, thus becoming a Peer of France. He died at Paris on 17 February 1819.
