In the House of Commons, where he represented Sussex, Sackville defended Bacon and advo cated an aggressive policy for the recovery of the Rhenish Palat inate; twice he was ambassador to France, and he was interested in Virginia, and the Bermuda islands. Under Charles I. he was a privy councillor and lord chamberlain to Henrietta Maria. At the outbreak of the Civil War, he joined the king at York, but he endeavoured to secure peace. At Oxford he was lord chamber lain to the king and lord president of his council, but Charles did not altogether approve of his pacific attitude. He died on July 17, 165 2. His wife Mary (d. 1645) , daughter of Sir George Curzon, was governess to the sons of Charles I., the future Charles II. and James II.
