What countries control Antarctica?

Antarctica is not controlled by any single country. Instead, it is governed by the Antarctic Treaty, which was signed in 1959 and has been ratified by 53 countries. The treaty sets aside Antarctica as a scientific preserve and prohibits military activity, nuclear explosions, and the disposal of radioactive waste. The treaty also establishes a mechanism for international cooperation on scientific research in Antarctica.

The Antarctic Treaty does not recognize any territorial claims in Antarctica. However, several countries have made territorial claims, including Argentina, Australia, Chile, France, New Zealand, Norway, and the United Kingdom. These claims are not recognized by all countries, and there is no international agreement on which country has sovereignty over any part of Antarctica.
