Menorca was captured in 1708 by a joint British–Dutch force on behalf of Holy Roman Emperor Charles VI, during the War of the Spanish Succession. The British saw the island's potential as a naval base and sought to take full control. Its status as a British possession was confirmed by the Treaty of Utrecht in 1713. During the island's years as a British dependency, the capital was moved from Ciutadella de Menorca to Mahon, which then served as residence for the governor, the most famous being General Richard Kane. During this period the natural harbour leading to the town and surrounding settlements were sometimes collectively known as ""Port Mahon"" "(see map left)".
