United Kingdom vs. British Overseas Territories

The United Kingdom is a sovereign state comprising four countries: England, Scotland, Wales, Northern Ireland.

Separately, the UK governs 14 British Overseas Territories (e.g., Gibraltar, Falklands, Bermuda, Cayman Islands) and has a special relationship with three Crown Dependencies (Isle of Man, Guernsey, Jersey) which are self-governing but rely on the UK for defense and foreign affairs. The British Antarctic Territory claim is suspended under the Antarctic Treaty.
