Antarctica has no indigenous population, and so the human history of Antarctica does not begin until the 19th century, when the continent was first seen.
Early theories
In the Western world, belief in a Terra Australis - a vast continent located in the far south of the globe to "balance" out the northern lands of Europe, Asia and North Africa - had existed for centuries. European maps continued to show this hypothetical land of Antarctica until Captain James Cook and the crews of his expedition's ships, Resolution and Adventure, crossed the Antarctic Circle three times between 1772 and 1775 dispelling the myth. However, ice packs prevented Cook and his men from seeing the actual continent, which was smaller than had long been thought. In 1513, admiral Piri Reis drew a map that has been said to show part of the Antarctic continent
Exploration
The first confirmed sighting of Antarctica cannot be accurately attributed to one single person. It can, however, be narrowed down to three individuals. According to various sources [1] [2] [3][4], three men all sighted Antarctica within days or weeks of each other: Fabian von Bellingshausen (a captain in the Russian Imperial Navy), Edward Bransfield (a captain in the British navy), and Nathaniel Palmer (an American sealer out of Stonington, Connecticut). Bransfield supposedly saw Antarctica on January 27, 1820, three days before Palmer sighted land. It is certain that on January 28, 1820 (New Style), the expedition led by Fabian von Bellingshausen and Mikhail Petrovich Lazarev on two ships reached a point within 20 miles (32 km) of the Antarctic mainland and saw ice-fields there. On January 30, 1820, Bransfield approached Trinity Peninsula, the northernmost point of the Antarctic mainland, and went ashore on a pinnace.
Only slightly more than a year later, the first American landing on Antarctica was arguably by Captain John Davis, a sealer, who claimed to have set foot there on February 7, 1821, though this is not accepted by all historians.
After the North Magnetic Pole was located in 1831, explorers and scientists began looking for the South Magnetic Pole. One of the explorers, James Clark Ross, identified its approximate location, but was unable to reach it. He also mapped the Ross Ice Shelf, which was later named after him. The volcanoes Mount Erebus and Mount Terror on Ross Island were named for the two ships of Ross's expedition.
In 1897, an expedition led by Belgian Adrian de Gerlache left Antwerp, Belgium for Antarctica. The multi-national crew included a Romanian zoologist (Emil Racoviţă), a Polish geologist (Henryk Arctowski), a Belgian navigator/astronomer (George Lecointe), several Norwegians, including Roald Amundsen, and an American surgeon, Dr. Frederick Cook. In 1898, they became the first men to spend winter on Antarctica, when their ship Belgica became trapped in the ice. They became stuck on February 28, 1898, and only managed to get out of the ice on March 14, 1899. During their forced stay, several men lost their sanity, not only because of the Antarctic winter night and the endured hardship, but also because of the language problems between the different nationalities
The British National Antarctic Expedition (1901 - 1904), led by Robert Falcon Scott, came to within 857 km (463 nautical miles) of the South Pole from its base at McMurdo Sound.
In 1903 the Scottish National Antarctic Expedition established Osmond House, a meteorological observatory on Laurie Island in the South Orkneys. A year later, ownership was passed to Argentina and renamed to Orcadas Base. It's the continent's oldest permanent base[7], and was the only one for about 40 years.
Ernest Shackleton, who had been a member of Scott's expedition, organized and led the British Antarctic Expedition (1907-09), again with the primary objective of reaching the South Pole, and came within 180 km (97 nautical miles) before having to turn back. On this expedition, again based at McMurdo Sound, Shackleton, discovered the Beardmore Glacier and was the first to reach the polar plateau. During this expedition, parties led by T. W. Edgeworth David became the first to climb Mount Erebus and to reach the South Magnetic Pole.
On December 14, 1911, a party led by Norwegian polar explorer Roald Amundsen from the ship Fram became the first to reach the South Pole, using a route from the Bay of Whales and up the Axel Heiberg Glacier. Amundsen was followed by Robert Falcon Scott from the Terra Nova over a month later, using the route pioneered by Shackleton. Scott's party later died on the return journey after being delayed by a series of accidents, bad weather, and the declining physical condition of the men. The Amundsen-Scott base was later named after these two men
The Imperial Trans-Antarctic Expedition of 1914, led by Ernest Shackleton, set out to cross the continent via the pole, but their ship, the Endurance, was trapped and crushed by pack ice before they even landed. The expedition members survived after an epic journey on sledges over pack ice to Elephant Island. Then Shackleton and five others crossed the Southern Ocean, in an open boat called James Caird, and then trekked over South Georgia to raise the alarm at the whaling station Grytviken.
US Navy Rear Admiral Richard Evelyn Byrd led five expeditions to Antarctica during the 1930s, 1940s, and 1950s. He overflew the South Pole with pilot Bernt Balchen on November 28 and 29, 1929, to match his overflight of the North Pole in 1926. Byrd's explorations had science as a major objective and pioneered the use of aircraft on the continent. Byrd is credited with doing more for Antarctic exploration than any other explorer. His expeditions set the scene for modern Antarctic exploration and research.
It was not until October 31, 1956 that anyone set foot on the south pole again; on that day US Navy Rear Admiral George Dufek[8] (and others) successfully landed a R4D Skytrain (Douglas DC-3) aircraft.
During the International Geophysical Year of 1957 a large number of expeditions were mounted.
New Zealand mountaineer Sir Edmund Hillary led an expedition using farm tractors equipped for polar travel and arrived at the Pole in late 1957, the first expedition since Scott's to reach the South Pole over land. Hillary was laying supply depots for the British Trans-Antarctic expedition and in typical Hillary style "detoured" to the pole because the trip had gone well. Then in 1958, British explorer Sir Vivian Fuchs led a successful overland transpolar expedition that completed the journey that Shackleton had first envisaged.
The Antarctic Treaty and recent history
The Antarctic Treaty was signed on December 1, 1959 and came into force on June 23, 1961.
A baby, named Emilio Marcos de Palma, was born near Hope Bay on January 7, 1978, becoming the first baby born on the continent. He also was born farther south than anyone in history. The mother had been sent there by the Argentine government in order for Argentina to become the first country with a child born there.
On November 28, 1979, an Air New Zealand DC-10 on a sightseeing trip crashed into Mount Erebus on Ross Island, killing all 257 people on board.
In March 2002 the 5,500 km2 (2,120 square statute mile) Iceberg B-22 broke off from the Thwaites Ice Tongue and the Larsen B ice shelf on the Antarctic Peninsula, and shattered into small fragments. The ice shelf was 200 metres thick and had a surface area of 3,250 square kilometres.

The answser to your question is rather complicated. A few highlights of Antarctic exploration include ....
"The first systematic search for a southern continent didn't come until nearly the beginning of the eighteenth century. In September of 1699, the scientist Edmond Halley left England aboard the Pink Paramour to establish the true longitude of ports in South America and Africa, measure magnetic variations, and search for the mysterious Terra Australis Incognita. By January, he had crossed the Antarctic Convergence and on February 1, 1700 at 52°24'S, Halley made the first recorded sighting of tabular icebergs, which he sketched into the ship's logbook. However, the cold, stormy weather, and the danger of collision with an iceberg in the fog drove him north again."
"Near the end of February, 1775, Cook crossed his track of 1772, completing the first circumnavigation of Antarctica and proving once and for all that the southern continent, if one existed, was neither as large nor as habitable as once thought. He did believe there was a southern land mass, but that it was of little use to anyone."
"In 1820 the Antarctic continent was first seen by human eyes. Historians have disagreed on who those eyes belonged to; at least one possible claimant is believed to have seen land but mistaken it for ice at the time. Credit for being the first man to see the continent has been divided between three men who made separate voyages to Antarctica that year:
Fabian von Bellingshausen, a captain in the Russian Imperial Navy;
Edward Bransfield, a captain in the British navy;
Nathaniel Brown Palmer, an American sealer.
"The first recorded landing on the Antarctic continent took place on February 7, 1821. Men from the American sealer Cecilia, under Captain John Davis, landed at Hughes Bay (64°01'S) looking for seals. Though they were on shore for less than an hour, these men were the first humans to set foot on this new southern land. Davis correctly guessed that the land was a continent."
These sites give an excellent history and timeline of antarctic exploration.
