For many years, cartographers and European explorers speculated about the existence of the
Terra Australis Incognita, a vast territory located in the south of the
Strait of Magellan and
Tierra del Fuego and reached the
South Pole. The
Treaty of Tordesillas, signed on June 7 of 1494, set the areas of influence of
Spain and
Portugal, west and east, respectively, of a line running from pole to pole that was never demarcated (at 46° 37 'W in the Spanish classical interpretation, and further west, according to the Portuguese interpretation), so the Antarctic areas claimed by Chile today, while still unknown at that time, fell within the control of Spain. The treaty, backed by the papal bull
Ea quae pro bono pacis in 1506 was made mandatory for all Catholic countries, was not recognized by European non-Catholic states and even by some that were, like
France. For
Britain,
Dutch,
Russia and other countries, the Antarctic areas were considered
res nullius, a no man's land not subject to the occupation of any nation. In 1534, The Emperor
Charles V divided in three governorates the South American territory : •
New Castile or
Peru to
Francisco Pizarro, •
New Toledo or
Chile to
Diego de Almagro and •
New León or Magellanic Lands for
Simón de Alcazaba y Sotomayor, which was subsequently extended to the Straits of Magellan. In 1539, a new governorate was formed south of New León called
Terra Australis to
Pedro Sanchez de la Hoz. In 1554, the conqueror
Pedro de Valdivia, who led the Governorate of Chile, he talked to the
Council of the Indies to give the rights of New León and the
Terra Australis to
Jeronimo de Alderete, which, after the death of Valdivia the following year, became governor of Chile and annexed the Chilean colonial territory. Proof of this are numerous historical documents, among which include a Royal Decree of 1554: Later, in 1558, the Royal Decree of
Brussels it prompted the Chilean colonial government to
take ownership in our name from the lands and provinces that fall in the demarcation of the Spanish crown in Referring to the land
across the Strait, because at that time it was thought that
Tierra del Fuego was an integral part of the
Terra Australis. One of the most important works of Spanish literature, the
epic poem La Araucana by
Alonso de Ercilla (1569), is also considered by Chile as favorable to their argument, as you can read in the seventh stanza of his Canto I: In the fourth stanza of his Canto III: There are also stories and maps, both Chilean and Europeans, indicating the membership of the
Terra Australis Antarctica as part of the Captaincy General of Chile. The Spanish navigator
Gabriel de Castilla sailed from
Valparaiso in March 1603 in command of three ships in an expedition entrusted by his brother cousin
viceroy of Peru,
Luis de Velasco y Castilla, to repress the incursions of Dutch privateers in the Southern Seas, reaching 64 degrees south latitude. There have not founded in the Spanish archives documents confirming the reached latitude and sighted land; however, the story of the Dutch sailor Laurenz Claesz (is a testimony dateless, but probably after 1607), documents the latitude and time. Claesz said: Another Dutch document, published in
Amsterdam in three languages in 1622, says that at 64°S there are "very high and mountainous, snow cover, like the country of Norway, all white, land It seemed to extend to the Solomon Islands" This confirms a previous sighting of the lands would be the
South Shetland Islands. Other historians attribute the first sighting of Antarctic land to the Dutch marine
Dirk Gerritsz, which would have found the islands now known as South Shetland. According to his account, his ship was diverted from course by a storm after transposing the
Strait of Magellan, in the journey of a Dutch expedition to the
East Indies in 1599. There are doubts about the veracity of Gerritsz. At this time was already known the existence of a white continent in south of the
Drake Passage, separated from the
Tierra del Fuego. In 1772, the
British James Cook circumnavigated the waters of the
Southern Ocean. which was granted to
Pedro Sancho de la Hoz ==Economy==
