Background Antarctica, in 24 editions.

Speculation over the existence of a "southern land" was not confirmed until the early 1820s when British and American commercial operators and British and Russian national expeditions began exploring the Antarctic Peninsula region and other areas south of the Antarctic Circle. Not until 1838 1840 was it established that Antarctica was indeed a continent and not just a group of islands. Various Several exploration "firsts" were achieved in the early 20th century, including: 1902, first balloon flight (by British explorer Robert Falcon SCOTT); 1912, first to the South Pole (five Norwegian explorers under Roald AMUNDSEN); 1928, first fixed-wing aircraft flight (by Australian adventurer/explorer Sir Hubert WILKINS); 1929, first flight over the South Pole (by Americans Richard BYRD and Bernt BALCHEN); and 1935, first transantarctic flight (American Lincoln ELLSWORTH). century. Following World War II, there was an upsurge in scientific research on the continent. A number of countries have set up year-round research stations on Antarctica. Seven have made territorial claims, but no other country recognizes these claims. In order to form a legal framework for the activities of nations on the continent, an Antarctic Treaty was negotiated that neither denies nor gives recognition to existing territorial claims; signed in 1959, it entered into force in 1961.
