MONTMORENCY, ANNE, Duc DE (1493-1567), con stable of France, was born at Chantilly, and was brought up with the future King Francis I., whom he followed into Italy in 1515, distinguishing himself especially at Marignano. In 1516 he be came governor of Novara; in 1520 he was present at the Field of Cloth of Gold, and afterwards had charge of important negotia tions in England. He was made marshal of France in 1522, accom panied Francis into Italy in 1524, and was taken prisoner at Pavia in 1525. Released soon afterwards, he was one of the negotiators of the treaty of Madrid, and in 1530 reconducted the king's sons into France. On the renewal of the war by .Charles V.'s invasion of France in 1536, Montmorency compelled the emperor to raise the siege of Marseilles; he afterwards accompanied the king of France into Picardy, and on the termination of the Netherlands campaign marched to the relief of Turin. In 1538, on the rati fication of the ten years' truce, he was rewarded with the office of constable, but in 1541 he fell into disgrace, and did not return to public life until the accession of Henry II. in 1547. In 1548 he repressed the insurrections in the south-west, particularly at Bordeaux, with great severity, and in 1549-50 conducted the war in the Boulonnais.
Soon afterwards Montmorency was fighting in the north-east. His attempt to relieve St. Quentin resulted in his defeat and cap tivity (Aug. io, 1557), and he did not regain his liberty until the peace of Cateau-Cambresis in 1559. Supplanted in the interval by the Guises, he was treated with coldness by the new king, Francis II., and compelled to give up his mastership of the royal house hold—his son, however, being appointed marshal by way of in demnity. On the accession of Charles IX. in 156o he resumed his offices and dignities, and, uniting with his former enemies, the Guises, played an important part in the Huguenot war of 1562. He fell into the hands of the enemy at Dreux, and was not lib erated until the treaty of Amboise (March 19, 1563). In 1567 he again triumphed at St. Denis, but was wounded, and died in Paris, on March 15, 1567.
