The Republic of Ireland is situated on the island of Ireland, which is itself one of the archipelago known as the British Isles (a term which is offensive to certain people from the Republic). Other entities which sit on the British Isles include the Isle of Man and the "United Kingdom of Great Britain and Northern Ireland", comprising four nations (England, Wales, Scotland, and Northern Ireland). Great Britain is one of the British Isles, and it contains most of Wales, Scotland, and England.
