Lying halfway between England and Northern Ireland in the Irish Sea, the Isle of Man has been inhabited for centuries by the Celtic Manx people. Established by the Vikings in the ninth century, the Manx parliament, the Tynwold, has autonomy from the UK in a number of matters, including taxation, and the death penalty was only officially abolished in 1993. The islanders have used this independence to establish a thriving financial and business sector, which has aided employment as the traditional industries of agriculture and fishing decline. There is still a shellfishing industry, specializing in scallops. Tourism is also important; there are more than 200,000 visitors each year. The Manx culture received a boost in 1993, when the local language, which was in danger of dying out, began to be taught in the island's schools once more. The Calf of Man, which is a small uninhabited island, is administered as a nature reserve.
