The Two Sovereign Nations of the British Isles

The British Isles (archipelago: Great Britain, Ireland, +6,000 smaller islands) contain exactly two sovereign states:

1. United Kingdom of Great Britain and Northern Ireland

• Composition: England, Scotland, Wales (Great Britain) + Northern Ireland
• Capital: London
• Population: ~67M (2024)
• Status: Unitary parliamentary constitutional monarchy
• International: UN Security Council permanent member, NATO, G7, Commonwealth

2. Republic of Ireland (Poblacht na hÉireann)

• Capital: Dublin
• Population: ~5.3M (2024)
• Status: Unitary parliamentary republic

Not Countries (But Often Confused)

• Isle of Man, Guernsey, Jersey: Crown Dependencies (self-governing, UK responsible for defense/foreign affairs). Not sovereign.
• Overseas Territories (14): e.g., Gibraltar, Falklands, Bermuda — UK sovereignty, not part of British Isles geographically.

Terminology Note

"British Isles" is a geographic term. Some in Ireland prefer "Britain and Ireland" or "Atlantic Archipelago" due to political connotations. The two sovereign states cooperate via British-Irish Council, Common Travel Area, Good Friday Agreement institutions.
