Antarctica Territorial Claims: 7 Nations, No Sovereignty Recognized

Seven countries assert sectors, but the 1959 Antarctic Treaty freezes all claims, dedicates the continent to science, and bans military/mineral activity.

1. Argentina – Argentine Antarctica (South Shetlands to Pole)
2. Australia – Australian Antarctic Territory (160°E–44°38'E)
3. Chile – Chilean Antarctic Territory (Peninsula to Pole)
4. France – Adélie Land (142°02'E–136°11'E)
5. New Zealand – Ross Dependency (160°E–150°W)
6. Norway – Peter I Island, Bouvet Island
7. United Kingdom – British Antarctic Territory (20°W–80°W)

Claims overlap; none are universally recognized. The Treaty makes Antarctica a "common heritage of mankind."
