military activity; for the purposes of the treaty system, Antarctica is defined as all the land and
ice shelves south of
60°S latitude. Since September 2004, the
Antarctic Treaty Secretariat, which implements the treaty system, is headquartered in
Buenos Aires, Argentina.
The main treaty was opened for signature on December 1, 1959, and officially
entered into force on June 23, 1961. The original signatories were the 12 countries active in Antarctica during the

History
1940s
After the Second World War, the U.S. considered establishing a claim in Antarctica. From August 26, 1946, and until the beginning of 1947, it carried out
Operation Highjump
Operation HIGHJUMP, officially titled The United States Navy Antarctic Developments Program, 1946–1947, (also called Task Force 68), was a United States Navy (USN) operation to establish the Antarctic research base Little America IV. The opera ...
, the largest military expeditionary force that the United States had ever sent to Antarctica, consisting of 13 ships, 4,700 men, and numerous aerial devices.
Its goals were to train military personnel and to test materiel in conditions of extreme cold for a hypothetical war in the Antarctic.
On September 2, 1947, the quadrant of Antarctica in which the United States was interested (between 24° W and
90° W) was included as part of the security zone of the
Inter-American Treaty of Reciprocal Assistance, committing its members to defend it in case of external aggression.
In August 1948, the United States proposed that Antarctica be under the guardianship of the United Nations, as a trust territory administered by Argentina, Australia, Chile, France, the United States, the United Kingdom, and New Zealand. This idea was rejected by Argentina, Australia, Chile, France, and Norway. Before the rejection, on August 28, 1948, the United States proposed to the claimant countries some form of internationalization of Antarctica, and this was supported by the United Kingdom. Chile responded by presenting a plan to suspend all Antarctic claims for five to ten years, while negotiating a final solution, but this did not find acceptance.
In 1950, the interest of the United States to keep the Soviet Union away from Antarctica was frustrated, when the Soviets informed the claimant states that they would not accept any Antarctic agreement in which they were not represented. The fear that the USSR would react by making a territorial claim, bringing the Cold War to Antarctica, led the United States to make none.
International conflicts
Various international conflicts motivated the creation of an agreement for the Antarctic.
Some incidents had occurred during the
Second World War, and a new one occurred in
Hope Bay on February 1, 1952, when the Argentine military fired warning shots at a group of Britons. The response of the United Kingdom was to send a warship that landed marines at the scene on February 4. In 1949, Argentina, Chile, and the United Kingdom signed a Tripartite Naval Declaration committing not to send warships south of the
60th parallel south
The 60th parallel south is a circle of latitude that is 60 degrees south of Earth's equatorial plane. No land lies on the parallel—it crosses nothing but ocean. The closest land is a group of rocks north of Coronation Island (Melson Rocks or ...
, which was renewed annually until 1961 when it was deemed unnecessary when the treaty entered into force. This tripartite declaration was signed after the tension generated when Argentina sent a fleet of eight warships to Antarctica in February 1948.
On January 17, 1953, Argentina reopened the Lieutenant Lasala refuge on
Deception Island, leaving a sergeant and a corporal in the Argentine Navy. On February 15, in the incident on Deception Island, 32 royal marines landed from the British frigate
HMS ''Snipe'' armed with
Sten machine guns, rifles, and tear gas capturing the two Argentine sailors. The Argentine refuge and a nearby uninhabited Chilean shelter were destroyed, and the Argentine sailors were delivered to a ship from that country on February 18 in the
South Georgia Islands

patrolled its waters until April.
On May 4, 1955, the United Kingdom filed two lawsuits, against Argentina and Chile respectively, before the
International Court of Justice to declare the invalidity of the claims of the sovereignty of the two countries over Antarctic and sub-Antarctic areas. On July 15, 1955, the Chilean government rejected the jurisdiction of the court in that case, and on August 1, the Argentine government also did so, so on March 16, 1956, the claims were closed.
In 1956 and 1958,
India tried unsuccessfully to bring the Antarctic issue to the
United Nations General Assembly.
International Geophysical Year
In 1950 the
International Council of Scientific Unions (ICSU) had discussed the possibility of holding a third
International Polar Year. At the suggestion of the
World Meteorological Organization, the idea of the International Polar Year was extended to the entire planet, thus creating the
International Geophysical Year
The International Geophysical Year (IGY; french: Année géophysique internationale) was an international scientific project that lasted from 1 July 1957 to 31 December 1958. It marked the end of a long period during the Cold War when scientific ...
that took place between July 1, 1957, and December 31, 1958. In this event, 66 countries participated. At the ICSU meeting in Stockholm from September 9 to 11, 1957, the creation of a Special Committee for Antarctic Research (SCAR) was approved, inviting the twelve countries conducting Antarctic investigations to send delegates to integrate the committee, with the purpose of exchanging scientific information among its members regarding Antarctica. The SCAR was later renamed to the Scientific Committee for Research in Antarctica.
Both Argentina and Chile stated that research carried out on the continent during the International Geophysical Year would not give any territorial rights to the participants, and that the facilities that were erected during that year should be dismantled at the end of it. However, in February 1958 the United States proposed that the Antarctic investigations should be extended for another year, and the Soviet Union reported that it would maintain its scientific bases until the studies being carried out had been completed.
Negotiation of the treaty
Scientific bases increased international tension concerning Antarctica. The danger of the Cold War spreading to that continent caused the President of the United States,
Dwight D. Eisenhower, to convene an Antarctic Conference of the twelve countries active in Antarctica during the International Geophysical Year, to sign a treaty. In the first phase, representatives of the twelve nations met in Washington, who met in sixty sessions between June 1958 and October 1959 to define a basic negotiating framework. However, no consensus was reached on a preliminary draft. In the second phase, a conference at the highest diplomatic level was held from October 15 to December 1, 1959, when the Treaty was signed. The central ideas with full acceptance were the freedom of scientific research in Antarctica and the peaceful use of the continent. There was also a consensus for demilitarization and the maintenance of the
status quo

.
The positions of the United States, the Soviet Union, the United Kingdom, and New Zealand coincided in the establishment of an international administration for Antarctica, proposing that it should be within the framework of the United Nations. Australia and the United Kingdom expressed the need for inspections by observers, and the British also proposed the use of military personnel for logistical functions. Argentina proposed that all atomic explosions be banned in Antarctica, which caused a crisis that lasted until the last day of the conference, since the United States, along with other countries, intended to ban only those that were made without prior notice and without prior consultation. The support of the USSR and Chile for the Argentine proposal finally caused the United States to retract its opposition.
The signing of the treaty was the first arms control agreement that occurred in the framework of the Cold War, and the participating countries managed to avoid the internationalization of Antarctic
sovereignty.

* Treaty Between the Government of Australia and the Government of the French Republic on Cooperation in the Maritime Areas Adjacent to the French Southern and Antarctic Territories (TAAF), Heard Island and the McDonald Islands (Canberra, November 24, 2003)
* Agreement on Cooperative Enforcement of Fisheries Laws between the Government of Australia and the Government of the French Republic in the Maritime Areas Adjacent to the French Southern and Antarctic Territories, Heard Island and the McDonald Islands (Paris, January 8, 2007)
Meetings
The Antarctic Treaty System's yearly ''Antarctic Treaty Consultative Meetings (ATCM)'' are the international forum for the administration and management of the region. Only 29 of the 55 parties to the agreements have the right to participate in decision-making at these meetings, though the other 26 are still allowed to attend. The decision-making participants are the ''Consultative Parties'' and, in addition to the 12 original signatories, including 17 countries that have demonstrated their interest in Antarctica by carrying out substantial scientific activity there. The Antarctic Treaty also has ''Special Antarctic Treaty Consultative Meetings (SATCM)'', which are generally summoned to treat more important topics but are less frequents and Meetings of Experts.
Parties
As of 2022, there are 55 states party to the treaty,
29 of which, including all 12 original signatories to the treaty, have consultative (voting) status.
The consultative members include the 7 countries that claim portions of Antarctica as their territory. The 48 non-claimant countries do not recognize the claims of others. 40 parties to the Antarctic Treaty have also ratified the "Protocol on Environmental Protection to the Antarctic Treaty".
* Has an overlapping claim with another one or two claimants.
† Reserved the right to make a claim.
Antarctic Treaty Secretariat
The ''Antarctic Treaty Secretariat'' was established in Buenos Aires, Argentina in September 2004 by the Antarctic Treaty Consultative Meeting (ATCM). Jan Huber (the Netherlands) served as the first Executive Secretary for five years until August 31, 2009. He was succeeded on September 1, 2009, by Manfred Reinke (Germany). Reinke was succeeded by Albert Lluberas (Uruguay), who was elected in June 2017 at the 40th Antarctic Consultative Treaty Meeting in Beijing, China.
The tasks of the Antarctic Treaty Secretariat can be divided into the following areas:
* Supporting the annual Antarctic Treaty Consultative Meeting (ATCM) and the meeting of the Committee for Environmental Protection (CEP).
* Facilitating the exchange of information between the Parties required in the Treaty and the Environment Protocol.
* Collecting, storing, arranging and publishing the documents of the ATCM.
* Providing and disseminating public information about the Antarctic Treaty system and Antarctic activities.
Legal system
Antarctica currently has no permanent population and therefore it has no citizenship nor government. Personnel present on Antarctica at any time are always citizens or nationals of some sovereignty outside Antarctica, as there is no Antarctic sovereignty. The majority of Antarctica is claimed by one or more countries, but most countries do not explicitly recognize those claims. The area on the mainland between
90 degrees west and
150 degrees west is the only major land on Earth not claimed by any country. Until 2015 the interior of the Norwegian Sector, the extent of which had never been officially defined, was considered to be unclaimed. That year, Norway formally laid claim to the area between its
Queen Maud Land and the South Pole.
Governments that are party to the Antarctic Treaty and its Protocol on Environmental Protection implement the articles of these agreements, and decisions taken under them, through national laws. These laws generally apply only to their own citizens, wherever they are in Antarctica, and serve to enforce the consensus decisions of the consultative parties: about which activities are acceptable, which areas require permits to enter, what processes of environmental impact assessment must precede activities, and so on. The Antarctic Treaty is often considered to represent an example of the
common heritage of mankind principle.
Australia

Since the designation of the
Australian Antarctic Territory pre-dated the signing of the Antarctic Treaty, Australian laws that relate to Antarctica date from more than two decades before the Antarctic Treaty era. In terms of criminal law, the laws that apply to the
Jervis Bay Territory (which follows the laws of the
Australian Capital Territory) apply to the Australian Antarctic Territory. Key Australian legislation applying Antarctic Treaty System decisions include the ''Antarctic Treaty Act 1960'', the ''Antarctic Treaty (Environment Protection) Act 1980'' and the ''Antarctic Marine Living Resources Conservation Act 1981''.
United States
The
law of the United States, including certain criminal offences by or against U.S. nationals, such as murder, may apply to areas not under jurisdiction of other countries. To this end, the United States now stations special deputy
U.S. Marshals in Antarctica to provide a law enforcement presence.
Some U.S. laws directly apply to Antarctica. For example, the
Antarctic Conservation Act, Public Law 95-541, ''et seq.'', provides civil and criminal penalties for the following activities, unless authorized by regulation or
statute
A statute is a formal written enactment of a legislative authority that governs the legal entities of a city, state, or country by way of consent. Typically, statutes command or prohibit something, or declare policy. Statutes are rules made by le ...
