Wales is a country located on the island of Great Britain, bordered by England to the east and the Irish Sea to the west. It has a population of three million and is mountainous, with its highest peaks located in Snowdonia, including Snowdon which is the highest point. Wales has a distinct cultural identity and was historically inhabited by Celtic Britons, with Welsh nationalism emerging in the centuries after Roman withdrawal. The National Assembly for Wales was created in 1999 and holds responsibility for devolved policy matters. Wales' economy was traditionally based on agriculture and mining but now depends more on services and tourism.
