Farthest South (or Furthest South in British English) is the term for the most southerly latitudes reached by explorers before the first successful expedition to the South Pole in 1911.
Significant steps on the road to the pole were the discovery of lands south of Cape Horn in 1619, Captain James Cook's crossing of the Antarctic Circle in 1773, and the earliest confirmed sightings of the Antarctic mainland in 1820. From the late 19th century onward, the quest for Farthest South latitudes became a race to reach the pole, which culminated in Roald Amundsen's success in December 1911.
In the years before reaching the pole was a realistic objective, other motives drew adventurers southward. Initially, the driving force was the discovery of new trade routes between Europe and the Far East. After such routes had been established and the main geographical features of the Earth had been broadly mapped, the lure for mercantile adventurers was the great fertile continent of "Terra Australis" which, according to myth, lay hidden in the south. Belief in the existence of this supposed land of plenty persisted well into the 18th century; explorers were reluctant to accept the truth that slowly emerged, of a cold, harsh environment in the lands of the Southern Ocean.
James Cook's voyages of 1772–1775 demonstrated conclusively the likely hostile nature of any hidden lands. This caused a shift of emphasis in the first half of the 19th century, away from trade and towards sealing and whaling, and then exploration and discovery. After the first overwintering on continental Antarctica in 1898–99 (Adrien de Gerlache), the prospect of reaching the South Pole appeared realistic, and the race for the pole began. The British were pre-eminent in this endeavour, which was characterised by the rivalry between Robert Falcon Scott and Ernest Shackleton during the Heroic Age of Antarctic Exploration. Shackleton's efforts fell short; Scott reached the pole in January 1912 only to find that he had been beaten by the Norwegian Amundsen.
Early voyagers
In 1494, the principal maritime powers, Portugal and Spain, signed a treaty which drew the Tordesillas line down the middle of the Atlantic Ocean and allocated all trade routes to the east of the line to Portugal. That gave Portugal dominance of the only known route to the east–via the Cape of Good Hope and Indian Ocean, which left Spain, and later other countries, to seek a western route to the Pacific. The exploration of the south began as part of the search for such a route.Knox-Johnston, pp. 20–22
Unlike the Arctic, there is no evidence of human visitation or habitation in Antarctica or the islands around it prior to European exploration. The southernmost parts of South America were already inhabited by tribes such as the Selkʼnam/Ona, the Yagán/Yámana, the Alacaluf and the Haush. The Haush in particular made regular trips to Isla de los Estados, which was from the main island of Tierra del Fuego, suggesting that some of them may have been capable of reaching the islands near Cape Horn. Fuegian Indian artefacts and canoe remnants have also been discovered on the Falkland Islands, suggesting the capacity for even longer sea journeys. Chilean scientists have claimed that Amerinds visited the South Shetland Islands, due to stone artefacts recovered from bottom-sampling operations in Admiralty Bay, King George Island, and Discovery Bay, Greenwich Island, but the artefacts—two arrowheads—were later found to have been planted, possibly to reinforce Chilean claims to the area.
While the natives of Tierra del Fuego were not capable of true oceanic travel, there is some evidence of Polynesian visits to some of the sub antarctic islands to the south of New Zealand, although these are further from Antarctica than South America. There are also remains of a Polynesian settlement from the 13th century on Enderby Island in the Auckland Islands.O'Connor, Tom Polynesians in the Southern Ocean: Occupation of the Auckland Islands in Prehistory in New Zealand Geographic 69 (September–October 2004): 6–8)Anderson, Atholl, & Gerard R.

Dunedin: Ngai Tahu Development Report, 1999Anderson, Atholl Subpolar Settlement in South Polynesia Antiquity 79.306 (2005): 791–800 According to ancient legends, around 650 AD the Polynesian traveller Ui-te-Rangiora led a fleet of Waka Tīwai south until they reached "a place of bitter cold where rock-like structures rose from a solid sea". It is unclear from the legends how far south Ui-te-Rangiora penetrated, but it appears that he observed ice in large quantities. A shard of undated, unidentified pottery, reported as found in 1886 in the Antipodes Islands, has been associated with this expedition.
Ferdinand Magellan
Although Portuguese by birth, Ferdinand Magellan transferred his allegiance to King Charles I of Spain, on whose behalf he left Seville on 10 August 1519, with a squadron of five ships, in search of a western route to the Spice Islands in the East Indies. Success depended on finding a strait or passage through the South American land masses, or finding the southern tip of the continent and sailing around it. The South American coast was sighted on 6 December 1519, and Magellan moved cautiously southward, following the coast to reach latitude 49°S on 31 March 1520. Little if anything was known of the coast south of this point, so Magellan decided to wait out the southern winter here, and established the settlement of Puerto San Julian.
In September 1520, the voyage continued down the uncharted coast, and on 21 October reached 52°S. Here Magellan found a deep inlet which proved to be the strait he was seeking, later to be known by his name. Early in November 1520, as the squadron navigated through the strait, they reached its most southerly point at approximate latitude 54°S. This was a record Farthest South for a European navigator, though not the farthest southern penetration by man; the position was north of the Tierra del Fuego archipelago, where there is evidence of human settlement dating back thousands of years.
Francisco de Hoces
The first sighting of an ocean passage to the Pacific south of Tierra del Fuego is sometimes attributed to Francisco de Hoces of the Loaisa Expedition. In January 1526, his ship San Lesmes was blown south from the Atlantic entrance of the Magellan Strait to a point where the crew thought they saw a headland, and water beyond it, which indicated the southern extremity of the continent. There is speculation as to which headland they saw; conceivably it was Cape Horn. In parts of the Spanish-speaking world it is believed that de Hoces may have discovered the strait later known as the Drake Passage more than 50 years before Francis Drake, the British privateer.

Francis Drake
Francis Drake sailed from Plymouth on 15 November 1577, in command of a fleet of five ships under his flagship Pelican, later renamed the Golden Hinde. His principal objective was plunder, not exploration; his initial targets were the unfortified Spanish towns on the Pacific coasts of Chile and Peru. Following Magellan's route, Drake reached Puerto San Julian on 20 June. After nearly two months in harbour, Drake left the port with a reduced fleet of three ships and a small pinnace. His ships entered the Magellan Strait on 23 August and emerged in the Pacific Ocean on 6 September.Knox-Johnston, pp. 40–45
Drake set a course to the north-west, but on the following day, a gale scattered the ships. The Marigold was sunk by a giant wave; the Elizabeth managed to return into the Magellan Strait, later sailing eastwards back to England; the pinnace was lost later. The gales persisted for more than seven weeks. The Golden Hinde was driven far to the west and south, before clawing its way back towards land. On 22 October, the ship anchored off an island which Drake named "Elizabeth Island", where wood for the galley fires was collected and seals and penguins captured for food.
According to Drake's Portuguese pilot, Nuno da Silva, their position at the anchorage was 57°S. However, there is no island at that latitude. The as yet undiscovered Diego Ramírez Islands, at 56°30'S, are treeless and cannot have been the islands where Drake's crew collected wood. This indicates that the navigational calculation was faulty, and that Drake landed at or near the then unnamed Cape Horn, possibly on Horn Island itself. His final southern latitude can only be speculated as that of Cape Horn, at 55°59'S. In his report, Drake wrote: "The Uttermost Cape or headland of all these islands stands near 56 degrees, without which there is no main island to be seen to the southwards but that the Atlantic Ocean and the South Sea meet." This open sea south of Cape Horn became known as the Drake Passage even though Drake himself did not traverse it.
Willem Schouten
On 14 June 1615, Willem Schouten, with two ships Eendracht and Hoorn, set sail from Texel in the Netherlands in search of a western route to the Pacific. Hoorn was lost in a fire, but Eendracht continued southward. On 29 January 1616, Schouten reached what he discerned to be the southernmost cape of the South American continent; he named this point Kaap Hoorn (Cape Horn) after his hometown and his lost ship. Schouten's navigational readings are inaccurate—he placed Cape Horn at 57°48' south, when its actual position is 55°58'. His claim to have reached 58° south is unverified, although he sailed on westward to become the first European navigator to reach the Pacific via the Drake Passage.Knox-Johnston, pp. 57–59
Garcia de Nodal expedition
The next recorded navigation of the Drake Passage was achieved in February 1619, by the brothers Bartolome and Gonzalo Garcia de Nodal. The Garcia de Nodal expedition discovered a small group of islands about south-west of Cape Horn, at latitude 56°30'S. They named these the Diego Ramirez Islands after the expedition's pilot. The islands remained the most southerly known land on earth until Captain James Cook's discovery of the South Sandwich Islands in 1775.Knox-Johnston, pp. 60–61
Other discoveries
Other voyages brought further discoveries in the southern oceans; in August 1592, the English seaman John Davis had taken shelter "among certain Isles never before discovered"—presumed to be the Falkland Islands.Knox-Johnston, p. 52 In 1675, the English merchant voyager Anthony de la Roché visited South Georgia (the first Antarctic land discovered); in 1739 the Frenchman Jean-Baptiste Bouvet de Lozier discovered the remote Bouvet Island, and in 1772, his compatriot, Yves-Joseph de Kerguelen de Trémarec, found the Kerguelen Islands.
