The island is loyal to the English monarch, who is represented in the island by the Lieutenant-Governor. Past governors have included member of the De Carteret family of Jersey, the Andros family of Guernsey, from whom it was inherited by the Le Mesurier family who established a hereditary line of governors that lasted until 1825.
During the 19th Century, the British Government decided to construct a major harbour as part of its defence of the islands against the threat of attacks from France. These were not completed, although the breakwater remains the longest in United Kingdom. The construction efforts brought many labourers and their families to the island.
It was almost completely evacuated during the German Occupation of the Channel Islands. Four concentration camps were built on the island, including Lager Sylt an SS-run death camp.
The island has one parish St Anne.
