The United Kingdom of Great Britain and Northern Ireland (which is usually shortened to just the UK or United Kingdom) is a political union made of up of four countries, England, Scotland, Wales and Northern Ireland. England, Scotland and Wales share the island of Great Britain, which lies just off the northwest coast of continental Europe. The fourth country, Northern Ireland, is a portion of another island, which is split between Northern Ireland and the Republic of Ireland, an independent country, in the south. The UK also has overseas territories such as Bermuda and Gibraltar.
