marshal of France and one of Louis XIV's ablest diplomats.

Estrades served with distinction in the Low Countries during the Thirty Years' War, conducted a famous defense of Dunkirk (1651–52), and took part in later campaigns in Catalonia (1655), Italy (1657), and Holland (1672). He was mayor perpétuel of Bordeaux (to which the title of count was attached) from 1653 to 1674 and was made chevalier de l'Ordre du Saint Esprit in 1661 and marshal of France in 1675. Having been ambassador extraordinary to Holland (1646) and a participant in the conferences at Münster, he went as ambassador to London in 1661; the attempt of the Spanish ambassador there to have precedence over him led to a great triumph for France; and in 1662 he negotiated the purchase from England of Dunkirk, of which he became governor. He was again ambassador to Holland from 1663 to 1668 and also represented the French in the negotiations at Breda in 1667 and at Nijmegen from 1675 to 1678.
