Lord Chandos had connections with the Levant Company, for example through his father-in-law Sir Robert Barnard, who was a merchant. The Levant Company controlled the appointment of the British ambassador in Constantinople, and although Charles II had some reservations about his politics, Chandos was elected by the Company on 22 April 1680. Royal Instructions were issued on 29 December. Lord Chandos arrived in Constantinople as the ambassador on 22 July 1681. Having served for only three years, he was recalled in November 1684. He left Turkey in October 1687. At this time, the Ottoman Empire was making great advances into Europe, reaching the walls of Vienna.
