Entered into force June 23, 1961
The Antarctic Treaty, the earliest of the post-World War II arms limitation agreements, has significance both in itself and as a precedent. It demilitarized the Antarctic Continent and provided for its cooperative exploration and future use. It has been cited as an example of nations exercising foresight and working in concert to prevent conflict before it develops. Based on the premise that to exclude armaments is easier than to eliminate or control them once they have been introduced, the treaty served as a model, in its approach and even in its specific provisions, for later "non-armament" treaties -- the treaties that excluded nuclear weapons from outer space, from Latin America, and from the seabed.
By the 1950s, seven nations -- Argentina, Australia, Chile, France, New Zealand, Norway, and the United Kingdom -- claimed territorial sovereignty over areas of Antarctica. Claims of Argentina, Chile, and the United Kingdom overlapped. Eight other nations -- the United States, the Soviet Union, Belgium, Germany, Poland, Sweden, Japan, and South Africa -- had engaged in exploration but had put forward no specific claims. The United States did not recognize the claims of other governments and reserved the right to assert claims. The Soviet Union took a similar position.
Activities in the Antarctic had generally been conducted peacefully and cooperatively. Yet the possibility that exploitable economic resources might be found meant the possibility of future rivalry for their control. Moreover, isolated and uninhabited, the continent might at some time become a potential site for deploying nuclear weapons.
Fortunately, international scientific associations were able to work out arrangements for effective cooperation. In 1956 and 1957, for example, American meteorologists "wintered over" at the Soviet post Mirnyy, while Soviet meteorologists "wintered over" at Little America. These cooperative activities culminated in the International Geophysical Year of 1957-1958 (IGY), a joint scientific effort by 12 nations -- Argentina, Australia, Belgium, Chile, France, Japan, New Zealand, Norway, South Africa, the Soviet Union, the United Kingdom, and the United States -- to conduct studies of the Earth and its cosmic environment.
In the years after World War II, as interest grew in keeping the continent from becoming militarized, there began diplomatic discussion of the possibility of formalizing a demilitarization arrangement. On May 3, 1958, the United States proposed to the other 11 nations participating in the IGY that a conference be held, based on the points of agreement that had been reached in informal discussions:
(1) that the legal status quo of the Antarctic Continent remain unchanged;
(2) that scientific cooperation continue;
(3) that the continent be used for peaceful purposes only.
All 11 nations accepted the U.S. invitation. The Washington Conference on Antarctica met from October 15 to December 1, 1959. No insurmountable conflicts or issues divided the conference, and negotiations culminated in a treaty signed by all 12 nations on December 1, 1959. After the U.S. Senate provided its advice and consent, the U.S. ratification was deposited on August 18, 1960, and the treaty entered into force on June 23, 1961, when the formal ratifications of all the participating nations had been deposited.
The treaty provides that Antarctica shall be used for peaceful purposes only. It specifically prohibits "any measures of a military nature, such as the establishment of military bases and fortifications, the carrying out of military maneuvers, as well as the testing of any type of weapons." (The Treaty does not prohibit the use of military personnel or equipment, however, for scientific research or for any other peaceful purpose.) Nuclear explosions and the disposal of radioactive waste material in Antarctica are prohibited.
The Treaty provides for designation of observers to carry out inspections in all areas of Antarctica, including all stations, installations and equipment, and ships and aircraft at discharge or embarkation points. Each observer has complete freedom of access at any time to any or all areas of Antarctica. Currently there are 50 Parties to the treaty, of whom 28 are Consultative Parties that participate in decision-making at Antarctic Treaty Consultative Meetings (ATCMs). Consultative Parties now include the original 12 Contracting Parties, as well as Brazil, Bulgaria, China, Ecuador, Finland, Germany, India, Italy, Republic of Korea, the Netherlands, Peru, Poland, Spain, Sweden, Ukraine, and Uruguay. The United States has conducted 14 inspections since 1963.
For the first time, in 2012 the U.S teamed with another country to conduct joint inspections of third-party Antarctic stations. In January 2012, a team of four officials from the United States and four from the Russian Federation inspected research facilities operated jointly by France and Italy (Concordia), Italy (Mario Zucchelli), and New Zealand (Scott Base). And in November-December 2012, a similar US-Russia team inspected which research facilities operated by Belgium (Princess Elisabeth Station), China (Zhongshan Station), India (Bharati and Maitri), Japan (Syowa), and Norway (Troll) – all in East Antarctica. A report of this second phase inspection will be presented jointly by the United States and Russia at the next Antarctic Treaty Consultative Meeting.
Thirty-five ATCMs have been held in accordance with Article IX of the Treaty, most recently in Australia in June 2012. Numerous recommendations and measures in furtherance of the principles and objectives of the Treaty have been adopted, many of which have now entered into force. The next ATCM will be in Brussels, Belgium in May 2013.

Recognizing that it is in the interest of all mankind that Antarctica shall continue forever to be used exclusively for peaceful purposes and shall not become the scene or object of international discord;
Acknowledging the substantial contributions to scientific knowledge resulting from international cooperation in scientific investigation in Antarctica;
Convinced that the establishment of a firm foundation for the continuation and development of such cooperation on the basis of freedom of scientific investigation in Antarctica as applied during the International Geophysical Year accords with the interests of science and the progress of all mankind;
Convinced also that a treaty ensuring the use of Antarctica for peaceful purposes only and the continuance of international harmony in Antarctica will further the purposes and principles embodied in the Charter of the United Nations;
