The Antarctic Treaty and related agreements, collectively known as the Antarctic Treaty System (ATS), regulate international relations with respect to Antarctica, Earth's only continent without a native human population. It was the first arms control agreement established during the Cold War, designating the continent as a scientific preserve, establishing freedom of scientific investigation, and banning 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.
A micronation is a political entity whose representatives claim that they belong to an independent nation or sovereign state, but which lacks legal recognition by any sovereign state. Micronations are classified separately from de facto states and quasi-states; they are also not considered to be autonomous or self-governing as they lack the legal basis in international law for their existence. The activities of micronations are almost always trivial enough to be ignored rather than disputed by the established nations whose territory they claim—referred to in micronationalism as "macronations". Several micronations have issued coins, flags, postage stamps, passports, medals and other state-related items, some as a source of revenue. Motivations for the creation of micronations include theoretical experimentation, political protest, artistic expression, personal entertainment and the conduct of criminal activity. The study of micronationalism is known as micropatriology or micropatrology.
The history of Antarctica emerges from early Western theories of a vast continent, known as Terra Australis, believed to exist in the far south of the globe. The term Antarctic, referring to the opposite of the Arctic Circle, was coined by Marinus of Tyre in the 2nd century AD.
The Ross Dependency is a region of Antarctica defined by a sector originating at the South Pole, passing along longitudes 160° east to 150° west, and terminating at latitude 60° south. It is claimed by New Zealand, a claim accepted by the other six countries with territorial claims in Antarctica. Under the 1961 Antarctic Treaty, of which all territorial claimants are signatories, including New Zealand, all claims are held in abeyance. Article IV states: "No acts or activities taking place while the present Treaty is in force shall constitute a basis for asserting, supporting or denying a claim to territorial sovereignty in Antarctica or create any rights of sovereignty in Antarctica".
A demilitarized zone is an area in which treaties or agreements between states, military powers or contending groups forbid military installations, activities, or personnel. A DZ often lies along an established frontier or boundary between two or more military powers or alliances. A DZ may sometimes form a de facto international border, such as the Korean Demilitarized Zone. Other examples of demilitarized zones are a 9-mile wide area between Iraq and Kuwait; Antarctica ; and outer space.
The British Antarctic Territory (BAT) is a sector of Antarctica claimed by the United Kingdom as one of its 14 British Overseas Territories, of which it is by far the largest by area. It comprises the region south of 60°S latitude and between longitudes 20°W and 80°W, forming a wedge shape that extends to the South Pole, overlapped by the Antarctic claims of Argentina and Chile. The claim to the region has been suspended since the Antarctic Treaty came into force in 1961.
The Australian Antarctic Territory (AAT) is a part of East Antarctica claimed by Australia as an external territory. It is administered by the Australian Antarctic Division, an agency of the federal Department of Climate Change, Energy, the Environment and Water. The territory's history dates to a claim on Enderby Land made by the United Kingdom in 1841, which was subsequently expanded and eventually transferred to Australia in 1933. It is the largest territory of Antarctica claimed by any nation by area. In 1961, the Antarctic Treaty came into force. Article 4 deals with territorial claims, and although it does not renounce or diminish any pre-existing claims to sovereignty, it also does not prejudice the position of Contracting Parties in their recognition or non-recognition of territorial sovereignty. As a result, only four other countries — New Zealand, the United Kingdom, France, and Norway — recognise Australia's claim to sovereignty in Antarctica.
Marie Byrd Land (MBL) is an unclaimed region of Antarctica. With an area of 1,610,000 km2 (620,000 sq mi), it is the largest unclaimed territory on Earth. It was named after the wife of American naval officer Richard E. Byrd, who explored the region in the early 20th century.
The Chilean Antarctic Territory, or Chilean Antarctica, is a part of West Antarctica and nearby islands claimed by Chile. It comprises the region south of 60°S latitude and between longitudes 53°W and 90°W, partially overlapping the Antarctic claims of Argentina and of the United Kingdom. It constitutes the Antártica commune of Chile.
Micronations are ephemeral, self-proclaimed entities that claim to be independent sovereign states, but which are not acknowledged as such by any recognised sovereign state, or by any supranational organisation. The constant reiteration of the flag as a symbol of a something that exists by the entity that it symbolizes confirms the validity of the flag as an officially sanctioned and/or definitive symbol of an entity; therefore, there has been a close association between vexillology/vexillogic imagination in creating visual symbols that appear to legitimize micronational claims.
The Kingdom of Vikesland was a micronation in Manitoba, Canada. It was founded in 2005 by Christopher Barry Joseph Beyette, a television news cameraman employed by the CHUM network.
Seven sovereign states – Argentina, Australia, Chile, France, New Zealand, Norway, and the United Kingdom – have made eight territorial claims in Antarctica. These countries have tended to place their Antarctic scientific observation and study facilities within their respective claimed territories; however, a number of such facilities are located outside of the area claimed by their respective countries of operation, and countries without claims such as China, India, Italy, Japan, Pakistan, Russia, South Africa (SANAE), Poland, and the United States have constructed research facilities within the areas claimed by other countries. There are overlaps among the territories claimed by Argentina, Chile, and the United Kingdom.
Bir Tawil is a 2,060 km2 (795.4 sq mi) area of land along the border between Egypt and Sudan, which is uninhabited and claimed by neither country. When spoken of in association with the neighbouring Halaib Triangle, it is sometimes referred to as the Bir Tawil Triangle, despite the area's quadrilateral shape; the two regions border at a quadripoint.
The Grand Duchy of Flandrensis is a micronation with claims over some territories of Antarctica, which was founded in 2008 by the Belgian Niels Vermeersch. Flandrensis is not recognised by any country or government, nor is it their intention to get diplomatic recognition. Since 2021 the micronation is registered in Belgium as the environmental non-profit organization “vzw Groothertogdom Flandrensis”.
Travis McHenry is an American-born micronationalist and occultist.
The Antarctic Micronational Union (AMU) is an intermicronational organization that aims to regulate micronational claims in Antarctica. The purpose of the AMU is to protect the claims of its members against other claimants.
International competition extended to the continent of Antarctica during the World War II era, though the region saw no combat. During the prelude to war, Nazi Germany organised the 1938 Third German Antarctic Expedition to preempt Norway's claim to Queen Maud Land. The expedition served as the basis for a new German claim, called New Swabia. A year later, the United States Antarctic Service Expedition established two bases, which operated for two years before being abandoned. Responding to these encroachments, and taking advantage of Europe's wartime turmoil, the nearby nations of Chile and Argentina made their own claims. In 1940 Chile proclaimed the Chilean Antarctic Territory in areas already claimed by Britain, while Argentina proclaimed Argentine Antarctica in 1943 in an overlapping area.
