St. Helena is a remote volcanic island in the South Atlantic about 1,100 mi (1,770 km) from the west coast of Africa. It is famous as Napoléon's place of exile (1815–1821). The island was discovered in 1502 by João da Nova, a Spanish navigator in the service of Portugal. It was taken for England in 1659 by the East India Company and was brought under the direct government of the Crown in 1834. After the opening of the Suez Canal in 1870, St. Helena's importance as a port of call diminished. About two-thirds of the colony's budget is provided by the United Kingdom in the form of a subsidy.
Before September 1, 2009, St. Helena had two dependencies: Ascension (34 sq mi; 88 sq km), an island about 700 mi (1,127 km) northwest of St. Helena; and Tristan da Cunha (40 sq mi; 104 sq km), a group of six islands about 1,500 mi (2,414 km) south-southwest of St. Helena. A new constitution which began on September 1, 2009, came into force giving the three islands equal status in the territory.
