The primary legislation governing nationality in the United Kingdom is the British Nationality Act 1981, which came into force on 1 January 1983. Its provisions apply to the British Islands (comprising the United Kingdom (England, Wales, Scotland, and Northern Ireland) and the Crown dependencies of Jersey, Guernsey, and the Isle of Man) and the 14 British Overseas Territories.
The six classes of British nationality provide differing levels of civil and political rights, reflecting the United Kingdom's historical legacy as a colonial power. The primary form is British citizenship, which is linked to the British Islands and confers full rights. Those connected with a current overseas territory are classified as British Overseas Territories citizens (BOTCs), and since 2002, nearly all BOTCs, except those associated solely with Akrotiri and Dhekelia, have also held British citizenship. Other residual forms of British nationality generally linked to former colonies and now largely closed to new acquisition include the statuses of British Overseas citizen, British subject, British National (Overseas) and British protected person. These categories do not confer automatic right of abode in the United Kingdom and offer limited entitlements.
