Antarctic Treaty System

1 December 1959

The Antarctic Treaty System is the set of international agreements that governs the continent of Antarctica. The original treaty was signed in Washington by twelve countries that had taken part in the International Geophysical Year of 1957 and 1958, including seven that had claimed parts of the continent. It sets aside Antarctica for peaceful purposes and scientific research, bans military activity and nuclear explosions, and puts existing territorial claims on hold. It was later supplemented by agreements to protect seals and marine life and by the Madrid Protocol of 1991, which bans mining. Dozens of countries are now parties to the system.
