Sackville was returned to Elizabeth’s first Parliament for his family’s local borough and in 1563 for Aylesbury, probably through the intervention of his relation Thomas Smythe I. He made no known contribution to the business of the House, and soon after the end of the 1563 session he went to France and Italy. At Rome he was first imprisoned, then received in audience by Pope Pius IV, an obscure episode open to conflicting interpretation. He was back in England early in 1566, when his departure for Vienna on government business was delayed by his father’s illness and death. He succeeded to estates in Essex, Kent, Oxfordshire, Sussex and Yorkshire, and was granted the reversion to Knole, though he had to wait nearly 40 years for possession. However, just over a year after his father’s death, after being knighted by the Duke of Norfolk in the Queen’s presence at Westminster, he was, on the same day, made a peer, the first of only two really new peerages to be granted in the reign, the other being Secretary Cecil’s four years later. Thenceforth Buckhurst was frequently a trier of petitions in the Lords, exercised parliamentary patronage at Arundel, Lewes and Steyning, and from his eponymous seat in Sussex he held sway as lord lieutenant, while remaining above all a courtier and diplomat. The most important of his embassies was the so-called ‘expostulatory mission’ to the Low Countries from March to July 1587, after Leicester’s return to England. Though close to Burghley, Buckhurst was not, it appears, against Leicester until, in the Netherlands, he saw the result of Leicester’s ‘might’, ‘malice’ and ‘intolerable errors’, as Buckhurst put it to the Queen. But this frankness now resulted in his own recall and banishment from court. He had still not been allowed back in February 1588, but Leicester’s death in the following September altered the balance of power: Buckhurst was restored to favour and soon afterwards made KG. It was he who signed the treaty of peace with Henri IV of France in 1591. In 1598 he joined Burghley in an unsuccessful attempt to achieve peace with Spain, and went again to the Netherlands to make a new treaty. There are frequent references of his entertainment of foreign ambassadors in England.
He was made lord treasurer by Elizabeth in May 1599 in succession to Burghley, and re-appointed by James I. The problems that were to ruin his two successors did not come to a
