The upper Bio-Bio region had recently been opened for Chilean and foreign settlers due to the occupation of the Araucania , and huge extensions of former Mapuche land were available. The workers rebelled against
278-449: A free market economy that saw an increase in domestic and foreign private investment, although the copper industry and other important mineral resources were not opened to competition. In a plebiscite on 5 October 1988, Pinochet was denied a second eight-year term as president (56% against 44%). Chileans elected a new president and the majority of members of a bicameral congress on 14 December 1989. Christian Democrat Patricio Aylwin ,
417-669: A national referendum in April 2020 regarding the creation of a new Constitution, later postponed to October due to the COVID-19 pandemic . On 25 October 2020, Chileans voted 78.28 per cent in favor of a new constitution, while 21.72 per cent rejected the change. Voter turnout was 51 percent. An election for the members of the Constitutional Convention was held in Chile between 15 and 16 May 2021. On 19 December 2021,

However, the Civil War had also been a contest between those who favored the development of local industries and powerful Chilean banking interests, particularly the House of Edwards which had strong ties to foreign investors. Soon after, the country engaged in a vastly expensive naval arms race with Argentina that nearly led to war, as well because of the Puna de Atacama dispute . After
695-576: A plurality of votes in a three-way contest, followed by candidates Radomiro Tomic for the Christian Democrat Party and Jorge Alessandri for the Conservative Party. Allende was not elected with an absolute majority, receiving fewer than 35% of the votes. The Chilean Congress conducted a runoff vote between the leading candidates, Allende and former president Jorge Alessandri, and, keeping with tradition, chose Allende by

The first confirmed landing was by a Norwegian team in 1895. In the early 20th century, there were a few expeditions into the interior of the continent. British explorers Robert Falcon Scott and Ernest Shackleton were
973-626: A campaign of domestic political and economical destabilization, some of which was backed by the United States. By early 1973, inflation was out of control. On 26 May 1973, Chile's Supreme Court, which was opposed to Allende's government, unanimously denounced Allende's disruption of the legality of the nation . Although illegal under the Chilean constitution, the court supported and strengthened Pinochet's soon-to-be seizure of power. A military coup overthrew Allende on 11 September 1973. As

The existence of life there is thought to strengthen the argument for the possibility of life on Jupiter 's moon Europa , which may have water beneath its water-ice crust. There exists a community of extremophile bacteria in the highly alkaline waters of Lake Untersee . The prevalence of highly resilient creatures in such inhospitable areas could further bolster
1946-701: A number of mountain ranges in the region, the most prominent being the Ellsworth Mountains. The presence of the West Antarctic Rift System has resulted in volcanism along the border between West and East Antarctica, as well as the creation of the Transantarctic Mountains. East Antarctica is geologically varied. Its formation began during the Archean Eon (4,000 Ma–2,500 Ma), and stopped during

On 15 November, most of the political parties represented in the National Congress signed an agreement to call
2224-536: A period of major reform. Under the slogan "Revolution in Liberty", the Frei administration embarked on far-reaching social and economic programs, particularly in education, housing, and agrarian reform , including rural unionization of agricultural workers. By 1967, however, Frei encountered increasing opposition from leftists, who charged that his reforms were inadequate, and from conservatives, who found them excessive. At
2363-710: A prolonged struggle, including infighting from Bernardo O'Higgins , who challenged Carrera's leadership. Intermittent warfare continued until 1817. With Carrera in prison in Argentina, O'Higgins and anti-Carrera cohort José de San Martín , hero of the Argentine War of Independence , led an army that crossed the Andes into Chile and defeated the royalists. On 12 February 1818, Chile was proclaimed an independent republic . The political revolt brought little social change, however, and 19th-century Chilean society preserved
2502-490: A reformist president, Arturo Alessandri , whose program was frustrated by a conservative congress. In the 1920s, Marxist groups with strong popular support arose. A military coup led by General Luis Altamirano in 1924 set off a period of political instability that lasted until 1932. Of the ten governments that held power in that period, the longest lasting was that of General Carlos Ibáñez del Campo , who briefly held power in 1925 and then again between 1927 and 1931 in what
2641-740: A vote of 153 to 35. Frei refused to form an alliance with Alessandri to oppose Allende, on the grounds that the Christian Democrats were a workers' party and could not make common cause with the right wing. An economic depression that began in 1972 was exacerbated by capital flight , plummeting private investment, and withdrawal of bank deposits in response to Allende's socialist program. Production fell and unemployment rose. Allende adopted measures including price freezes, wage increases, and tax reforms, to increase consumer spending and redistribute income downward. Joint public-private public works projects helped reduce unemployment. Much of

As a result, the Richard Nixon administration organized and inserted secret operatives in Chile, in order to swiftly destabilize Allende's government. In addition, US financial pressure restricted international economic credit to Chile. The economic problems were also exacerbated by Allende's public spending, financed mostly through printing money, and by poor credit ratings given by commercial banks.

10147-631: The city of Santiago on 12 February 1541. Although the Spanish did not find the extensive gold and silver they sought, they recognized the agricultural potential of Chile's central valley, and Chile became part of the Spanish Empire . Conquest took place gradually, and the Europeans suffered repeated setbacks. A massive Mapuche insurrection that began in 1553 resulted in Valdivia's death and
10286-584: The climate cooled, though flora remained. After deglaciation during the latter half of the Early Permian , the land became dominated by glossopterids (an extinct group of seed plants with no close living relatives), most prominently Glossopteris , a tree interpreted as growing in waterlogged soils, which formed extensive coal deposits. Other plants found in Antarctica during the Permian include Cordaitales , sphenopsids , ferns, and lycophytes . At
10425-527: The colonial authorities in Sydney officially renamed the continent of New Holland to Australia, leaving the term "Terra Australis" unavailable as a reference to Antarctica. Over the following decades, geographers used phrases such as "the Antarctic Continent". They searched for a more poetic replacement, suggesting names such as Ultima and Antipodea . Antarctica was adopted in the 1890s, with
10564-568: The colony in addition to the Mapuche, as was shown by Sir Francis Drake 's 1578 raid on Valparaíso, the colony's principal port. Chile hosted one of the largest standing armies in the Americas, making it one of the most militarized of the Spanish possessions, as well as a drain on the treasury of the Viceroyalty of Peru . The first general census was conducted by the government of Agustín de Jáuregui between 1777 and 1778; it indicated that
10703-775: The command of John Williams Wilson , the Magallanes Region started to be controlled by country in 1843 , while the Antofagasta Region , at the time in dispute with Bolivia , began to fill with people. After the Chilean Civil War of 1829–1830 in which the conservatives won, under the Joaquín Prieto Administration, the Chilean Constitution of 1833 was written and put into effect with high influence from
10842-510: The continent as a World Park . The Southern Ocean Whale Sanctuary was established in 1994 by the International Whaling Commission . It covers 50 million km (19 million sq mi) and completely surrounds the Antarctic continent. All commercial whaling is banned in the zone, though Japan has continued to hunt whales in the area, ostensibly for research purposes. Despite these protections,
10981-599: The continent's edge, strong katabatic winds off of the polar plateau often blow at storm force . During the summer, more solar radiation reaches the surface at the South Pole than at the equator because of the 24 hours of sunlight received there each day. Climate change caused by greenhouse gas emissions from human activities occurs everywhere on Earth, and while Antarctica is less vulnerable to it than any other continent, climate change in Antarctica has been observed. Since 1959, there has been an average temperature increase of >0.05 °C/decade since 1957 across
11120-496: The continent, although it had been uneven. West Antarctica warmed by over 0.1 °C/decade from the 1950s to the 2000s, and the exposed Antarctic Peninsula has warmed by 3 °C (5.4 °F) since the mid-20th century. The colder, stabler East Antarctica had been experiencing cooling until the 2000s. Around Antarctica, the Southern Ocean has absorbed more oceanic heat than any other ocean, and has seen strong warming at depths below 2,000 m (6,600 ft). Around
11259-408: The country to renounce to its claims in the rest of East Patagonia after a dispute that started in 1842 . As a result of the War of the Pacific with Peru and Bolivia (1879–83), Chile expanded its territory northward by almost one-third, eliminating Bolivia's access to the Pacific, and acquired valuable nitrate deposits, the exploitation of which led to an era of national affluence. Chile had joined
11398-802: The country, several hundred committed Chilean revolutionaries joined the Sandinista army in Nicaragua , guerrilla forces in Argentina or training camps in Cuba , Eastern Europe and Northern Africa. In the late 1980s, largely as a result of events such as the 1982 economic collapse and mass civil resistance in 1983–88, the government gradually permitted greater freedom of assembly, speech , and association, to include trade union and political activity. The government launched market-oriented reforms with Hernán Büchi as Minister of Finance. Chile moved toward
11537-628: The country. The years of the regime were marked by human rights violations . Chile actively participated in Operation Condor . In October 1973, at least 72 people were murdered by the Caravan of Death . According to the Rettig Report and Valech Commission , at least 2,115 were killed, and at least 27,265 were tortured (including 88 children younger than 12 years old). In 2011, Chile recognized an additional 9,800 victims, bringing
11676-402: The creation of small yet permanent polar ice caps. As CO 2 levels declined further the ice began to spread rapidly, replacing the forests that until then had covered Antarctica. Tundra ecosystems continued to exist on Antarctica until around 14-10 million years ago, when further cooling lead to their extermination. The geology of Antarctica, largely obscured by the continental ice sheet,
11815-522: The decision of the company Sociedad Puelma Tupper to evict the "occupiers" or "usurpers" of the lands that the Government had ceded to it, caused a break between the indigenous communities and the State. Despite some agreements between the parties, Carabineros de Chile forces began to harass the former residents. The uprising of the Mapuche peasants was rather the effect of the one set off by workers from
11954-404: The decrease of the heritage of the peoples Mapuche, who, pressured by the continuous state alienation of land, ended up as impoverished farmers in the Lonquimay sector. Another thesis proposes the conditions of semi-slavery that affected peasants and workers in the Lonquimay sector. This situation was somewhat similar to that of nitrate plants in northern Chile, where workers were strongly subject to
12093-549: The descendants of species that lived there millions of years ago. As such, they must have survived multiple glacial cycles . The species survived the periods of extremely cold climate in isolated warmer areas , such as those with geothermal heat or areas that remained ice-free throughout the colder climate. Invertebrate life of Antarctica includes species of microscopic mites such as Alaskozetes antarcticus , lice , nematodes , tardigrades , rotifers , krill and springtails . The few terrestrial invertebrates are limited to
12232-520: The destruction of many of the colony's principal settlements. Subsequent major insurrections took place in 1598 and in 1655. Each time the Mapuche and other native groups revolted, the southern border of the colony was driven northward. The abolition of slavery by the Spanish crown in 1683 was done in recognition that enslaving the Mapuche intensified resistance rather than cowing them into submission. Despite royal prohibitions, relations remained strained from continual colonialist interference. Cut off to
12371-538: The discovery of silver ore in Chañarcillo, and the growing trade of the port of Valparaíso, which led to conflict over maritime supremacy in the Pacific with Peru. At the same time, attempts were made to strengthen sovereignty in southern Chile intensifying penetration into Araucanía and colonizing Llanquihue with German immigrants in 1848. Through the founding of Fort Bulnes by the Schooner Ancud under
12510-582: The early Eocene. Around 53 Ma, Australia- New Guinea separated from Antarctica, opening the Tasmanian Passage . The Drake Passage opened between Antarctica and South America around 30 Ma, resulting in the creation of the Antarctic Circumpolar Current that completely isolated the continent. Models of Antarctic geography suggest that this current, as well as a feedback loop caused by lowering CO 2 levels, caused
12649-476: The effective number of deaths is estimated at 500, given that at that time the indigenous peoples were not present. registered in official books of the Civil Registry, so the count of victims was not rigorous (the official version of 1934 places them between just 150 and 200). According to other information provided by Olga Ulianova, a Chilean nationalized Russian historian, according to Comintern documents,
12788-489: The elevated inland, it can rise to about −30 °C in summer but fall below −80 °C in winter. The lowest natural air temperature ever recorded on Earth was −89.2 °C (−128.6 °F) at the Russian Vostok Station in Antarctica on 21 July 1983. A lower air temperature of −94.7 °C (−138.5 °F) was recorded in 2010 by satellite—however, it may have been influenced by ground temperatures and
12927-695: The end of his term, Frei had not fully achieved his party's ambitious goals. In the 1970 election, Senator Salvador Allende of the Socialist Party of Chile (then part of the " Popular Unity " coalition which included the Communists, Radicals, Social-Democrats, dissident Christian Democrats, the Popular Unitary Action Movement, and the Independent Popular Action), achieved a partial majority in
13066-553: The end of that period. During the colder Neogene (17–2.5 Ma), a tundra ecosystem replaced the rainforests. The climate of present-day Antarctica does not allow extensive vegetation to form. A combination of freezing temperatures, poor soil quality , and a lack of moisture and sunlight inhibit plant growth, causing low species diversity and limited distribution. The flora largely consists of bryophytes (25 species of liverworts and 100 species of mosses ). There are three species of flowering plants , all of which are found in
13205-587: The end of the Permian, the climate became drier and hotter over much of Gondwana, and the glossopterid forest ecosystems collapsed, as part of the End-Permian mass extinction . There is no evidence of any tetrapods having lived in Antarctica during the Paleozoic. The continued warming dried out much of Gondwana. During the Triassic, Antarctica was dominated by seed ferns (pteridosperms) belonging to
13344-548: The essence of the stratified colonial social structure, which was greatly influenced by family politics and the Roman Catholic Church . A strong presidency eventually emerged, but wealthy landowners remained powerful. Bernardo O'Higgins once planned to expand Chile by liberating the Philippines from Spain and incorporating the islands. In this regard he tasked the Scottish naval officer, Lord Thomas Cochrane, in
13483-654: The first rightist President in 20 years, defeating former President Eduardo Frei Ruiz-Tagle of the Concertación , for a four-year term succeeding Bachelet. Due to term limits, Sebastián Piñera did not stand for re-election in 2013, and his term expired in March 2014 resulting in Michelle Bachelet returning to office. Sebastián Piñera succeeded Bachelet again in 2018 as the President of Chile after winning
13622-454: The first to reach the magnetic South Pole in 1909, and the geographic South Pole was first reached in 1911 by Norwegian explorer Roald Amundsen . Antarctica is governed by about 30 countries , all of which are parties of the 1959 Antarctic Treaty System . According to the terms of the treaty, military activity, mining, nuclear explosions , and nuclear waste disposal are all prohibited in Antarctica. Tourism , fishing and research are
13761-417: The first use of the name being attributed to the Scottish cartographer John George Bartholomew . Antarctica has also been known by the moniker Great White South , after which British photographer Herbert Ponting named one of his books on Antarctic photography, possibly as a counterpart to the epithet Great White North for Canada . Positioned asymmetrically around the South Pole and largely south of
13900-402: The gap of 12,000 km (7,456 mi). Large animals such as some cetaceans and birds make the round trip annually. Smaller forms of life, such as sea cucumbers and free-swimming snails , are also found in both polar oceans. Factors that may aid in their distribution include temperature differences between the deep ocean at the poles and the equator of no more than 5 °C (9 °F) and
14039-502: The genus Dicroidium , which grew as trees. Other associated Triassic flora included ginkgophytes , cycadophytes , conifers , and sphenopsids. Tetrapods first appeared in Antarctica during the early Triassic , with the earliest known fossils found in the Fremouw Formation of the Transantarctic Mountains. Synapsids (also known as "mammal-like reptiles") included species such as Lystrosaurus , and were common during
14178-525: The globe to balance the northern lands of Europe, Asia, and North Africa—had existed as an intellectual concept since classical antiquity . The belief in such a land lasted until the European discovery of Australia . During the early 19th century, explorer Matthew Flinders doubted the existence of a detached continent south of Australia (then called New Holland ) and thus advocated for the "Terra Australis" name to be used for Australia instead. In 1824,
14317-519: The highly prized Patagonian toothfish which is marketed as Chilean sea bass in the U.S.—remains a problem. In analogy to the 1980 treaty on sustainable fishing , countries led by New Zealand and the United States negotiated a treaty on mining. This Convention on the Regulation of Antarctic Mineral Resource Activities was adopted in 1988. After a strong campaign from environmental organisations, first Australia and then France decided not to ratify
14456-553: The islands of the Kerguelen Plateau , the earliest of which formed around 40 Ma . Vinson Massif , in the Ellsworth Mountains , is the highest peak in Antarctica at 4,892 m (16,050 ft). Mount Erebus on Ross Island is the world's southernmost active volcano and erupts around 10 times each day. Ash from eruptions has been found 300 kilometres (190 mi) from the volcanic crater . There
14595-467: The main human activities in and around Antarctica. During the summer months, about 5,000 people reside at research stations , a figure that drops to around 1,000 in the winter. Despite the continent's remoteness, human activity has a significant effect on it via pollution , ozone depletion , and climate change . The melting of the potentially unstable West Antarctic ice sheet causes the most uncertainty in century-scale projections of sea level rise , and
14734-814: The major current systems or marine conveyor belts which are able to transport eggs and larva . About 1,150 species of fungi have been recorded in the Antarctic region, of which about 750 are non- lichen -forming. Some of the species, having evolved under extreme conditions, have colonised structural cavities within porous rocks and have contributed to shaping the rock formations of the McMurdo Dry Valleys and surrounding mountain ridges. The simplified morphology of such fungi, along with their similar biological structures , metabolism systems capable of remaining active at very low temperatures, and reduced life cycles, make them well suited to such environments. Their thick-walled and strongly melanised cells make them resistant to UV radiation. An Antarctic endemic species,
14873-671: The many Antarctic ice shelves , a process described by ice-sheet dynamics . East Antarctica comprises Coats Land , Queen Maud Land , Enderby Land , Mac . Robertson Land , Wilkes Land , and Victoria Land. All but a small portion of the region lies within the Eastern Hemisphere . East Antarctica is largely covered by the East Antarctic Ice Sheet . There are numerous islands surrounding Antarctica, most of which are volcanic and very young by geological standards. The most prominent exceptions to this are
15012-675: The north by desert, to the south by the Mapuche, to the east by the Andes Mountains, and to the west by the ocean, Chile became one of the most centralized, homogeneous territories in Spanish America. Serving as a sort of frontier garrison , the colony found itself with the mission of forestalling encroachment by both the Mapuche and Spain's European enemies, especially the English and the Dutch . Buccaneers and pirates menaced
15151-587: The north'). Antarcticus is derived from the Greek ἀντι- ('anti-') and ἀρκτικός ('of the Bear ', 'northern'). The Greek philosopher Aristotle wrote in Meteorology about an "Antarctic region" in c. 350 BCE . The Greek geographer Marinus of Tyre reportedly used the name in his world map from the second century CE, now lost. The Roman authors Gaius Julius Hyginus and Apuleius used for
15290-544: The north, Bolivia to the northeast, Argentina to the east, and the Drake Passage to the south. The country also controls several Pacific islands, including Juan Fernández , Isla Salas y Gómez , Desventuradas , and Easter Island , and claims about 1,250,000 square kilometers (480,000 sq mi) of Antarctica as the Chilean Antarctic Territory . The capital and largest city of Chile
15429-578: The ocean around Antarctica, including some that normally reside in the Arctic. The emperor penguin is the only penguin that breeds during the winter in Antarctica; it and the Adélie penguin breed farther south than any other penguin. A Census of Marine Life by some 500 researchers during the International Polar Year was released in 2010. The research found that more than 235 marine organisms live in both polar regions, having bridged
15568-433: The overall number of migrants was small. This effect might be related to externalities : the surrounding population adopted a similar behavior as the small non-European immigrant group, and new schools were created. Ironically, there might have been positive spillover effects from the educational investment made by migrants, at the same time numeracy might have been reduced by the greater inequality in these regions. However,
15707-402: The population consisted of 259,646 inhabitants: 73.5% of European descent , 7.9% mestizos , 8.6% indigenous peoples and 9.8% blacks. Francisco Hurtado, Governor of the province of Chiloé , conducted a census in 1784 and found the population consisted of 26,703 inhabitants, 64.4% of whom were whites and 33.5% of whom were natives. The Diocese of Concepción conducted a census in areas south of
15846-461: The positive effects of immigration were apparently stronger. In 1808, Napoleon's enthronement of his brother Joseph as the Spanish King precipitated the drive by Chile for independence from Spain . A national junta in the name of Ferdinand – heir to the deposed king – was formed on 18 September 1810. The Government Junta of Chile proclaimed an autonomous government for Chile within
15985-424: The record for the lowest measured temperature on Earth , −89.2 °C (−128.6 °F). The coastal regions can reach temperatures over 10 °C (50 °F) in the summer. Native species of animals include mites , nematodes , penguins , seals and tardigrades . Where vegetation occurs, it is mostly in the form of lichen or moss . The ice shelves of Antarctica were probably first seen in 1820, during
16124-558: The result from the arbitral award of the Andes resolved by the British Crown . In 1903 the Puna de Atacama dispute was solved. In 1904 Chile and Bolivia signed a Treaty of Peace and Friendship which clarified the border between both countries. The Chilean economy partially degenerated into a system protecting the interests of a ruling oligarchy . By the 1920s, the emerging middle and working classes were powerful enough to elect
16263-539: The saline Antarctic bottom water , weakening the lower cell of the Southern Ocean overturning circulation (SOOC). According to some research, a full collapse of the SOOC may occur a between 1.7 °C (3.1 °F) and 3 °C (5.4 °F) of global warming, although the full effects are expected to occur over multiple centuries; these include less precipitation in the Southern Hemisphere but more in
16402-480: The same melting also affects the Southern Ocean overturning circulation , which can eventually lead to significant impacts on the Southern Hemisphere climate and Southern Ocean productivity. The name given to the continent originates from the word antarctic , which comes from Middle French antartique or antarctique ('opposite to the Arctic ') and, in turn, the Latin antarcticus ('opposite to
16541-667: The similarity of the valley of the Aconcagua with that of the Casma Valley in Peru, where there was a town and valley named Chili . Other theories say Chile may derive its name from a Native American word meaning either 'ends of the earth' or 'sea gulls'; from the Mapuche word chilli , which may mean 'where the land ends'" or from the Quechua chiri , 'cold', or tchili , meaning either 'snow' or "the deepest point of
16680-482: The small islands of San Ambrosio and San Felix . These islands are notable because they extend Chile's claim to territorial waters out from its coast into the Pacific Ocean. The northern Atacama Desert contains great mineral wealth, primarily copper and nitrates . The relatively small Central Valley, which includes Santiago, dominates the country in terms of population and agricultural resources. This area
16819-406: The species of fungi, which are apparently endemic to Antarctica, live in bird dung, and have evolved so they can grow inside extremely cold dung, but can also pass through the intestines of warm-blooded animals. Throughout its history, Antarctica has seen a wide variety of plant life. In the Cretaceous , it was dominated by a fern- conifer ecosystem, which changed into a temperate rainforest by
16958-540: The stand as one of the high-income countries in South America by 1870. On 9 September 1888, Chile took possession of Easter Island by the signing of a mutual will agreement with the local king, thanks to the efforts of the Bishop of Tahiti, Monsignor José María Verdier since the island was constantly attacked by slave merchants. The naval officer Policarpo Toro represented the Chilean Government and Atamu Tekena
17097-683: The sub-Antarctic islands. The flightless midge Belgica antarctica , the largest purely terrestrial animal in Antarctica, reaches 6 mm ( 1 ⁄ 4 in) in size. Antarctic krill , which congregates in large schools , is the keystone species of the ecosystem of the Southern Ocean, being an important food organism for whales, seals, leopard seals , fur seals, squid , icefish , and many bird species, such as penguins and albatrosses . Some species of marine animals exist and rely, directly or indirectly, on phytoplankton . Antarctic sea life includes penguins , blue whales , orcas , colossal squids and fur seals . The Antarctic fur seal
17236-535: The successful rescue of 33 trapped miners in 2010. On 5 August 2010, the access tunnel collapsed at the San José copper and gold mine in the Atacama Desert near Copiapó in northern Chile, trapping 33 men 700 meters (2,300 ft) below ground. A rescue effort organized by the Chilean government located the miners 17 days later. All 33 men were brought to the surface two months later on 13 October 2010 over
17375-448: The total number of killed, tortured or imprisoned for political reasons to 40,018. At the national stadium, filled with detainees, one of those tortured and killed was internationally known poet-singer Víctor Jara (see "Music and Dance", below). A new Constitution was approved by a controversial plebiscite on 11 September 1980, and General Pinochet became president of the republic for an eight-year term. After Pinochet obtained rule of
17514-592: The treaty. Instead, countries adopted the Protocol on Environmental Protection to the Antarctic Treaty (the Madrid Protocol), which entered into force in 1998. The Madrid Protocol bans all mining, designating the continent as a "natural reserve devoted to peace and science". The pressure group Greenpeace established a base on Ross Island from 1987 to 1992 as part of its attempt to establish
17653-569: The triple minister Diego Portales . Two other civil wars happened in Chile in the 1850s, one in 1851 and the other one in 1859 . Toward the end of the 19th century, the government in Santiago consolidated its position in the south by the Occupation of Araucanía . The Boundary treaty of 1881 between Chile and Argentina confirmed Chilean sovereignty over the Strait of Magellan but also made
17792-591: The universalization of the name Chile , after naming the Mapocho valley as such. The older spelling "Chili" was in use in English until the early 20th century before switching to "Chile". Stone tool evidence indicates humans sporadically frequented the Monte Verde valley area as long as 18,500 years ago. About 10,000 years ago, migrating Indigenous peoples settled in fertile valleys and coastal areas of what
17931-470: The various effects of climate change . Early world maps, like the 1513 Piri Reis map , feature the hypothetical continent Terra Australis . Much larger than and unrelated to Antarctica, Terra Australis was a landmass that classical scholars presumed necessary to balance the known lands in the northern hemisphere. Captain James Cook 's ships, HMS Resolution and Adventure , crossed
18070-412: The water when it freezes, which accumulates into pockets of brine that also harbour dormant microorganisms. When the ice begins to melt, brine pockets expand and can combine to form brine channels, and the algae inside the pockets can reawaken and thrive until the next freeze. Bacteria have also been found as deep as 800 m (0.50 mi) under the ice. It is thought to be likely that there exists
18209-524: Was a de facto dictatorship (although not really comparable in harshness or corruption to the type of military dictatorship that have often bedeviled the rest of Latin America). By relinquishing power to a democratically elected successor, Ibáñez del Campo retained the respect of a large enough segment of the population to remain a viable politician for more than thirty years, in spite of the vague and shifting nature of his ideology. When constitutional rule
18348-529: Was cooler, though fossils of land plants are known from then. Sand and silts were laid down in what is now the Ellsworth, Horlick , and Pensacola Mountains . Antarctica became glaciated during the Late Paleozoic icehouse beginning at the end of the Devonian period (360 Ma), though glaciation would substantially increase during the late Carboniferous . It drifted closer to the South Pole, and
18487-422: Was marked by severe left-right political polarization and turmoil, which culminated in the 1973 Chilean coup d'état that overthrew Salvador Allende 's democratically elected left-wing government . This was followed by a 16-year right-wing military dictatorship under Augusto Pinochet , which resulted in more than 3,000 deaths or disappearances . The regime ended in 1990, following a referendum in 1988 , and
18626-472: Was not recorded at a height of 2 m (7 ft) above the surface as required for official air temperature records. Antarctica is a polar desert with little precipitation ; the continent receives an average equivalent to about 150 mm (6 in) of water per year, mostly in the form of snow. The interior is dryer and receives less than 50 mm (2 in) per year, whereas the coastal regions typically receive more than 200 mm (8 in). In
18765-632: Was restored in 1932, a strong middle-class party, the Radicals, emerged. It became the key force in coalition governments for the next 20 years. During the period of Radical Party dominance (1932–52), the state increased its role in the economy. In 1952, voters returned Ibáñez del Campo to office for another six years. Jorge Alessandri succeeded Ibáñez del Campo in 1958, bringing Chilean conservatism back into power democratically for another term. The 1964 presidential election of Christian Democrat Eduardo Frei Montalva by an absolute majority initiated
18904-618: Was succeeded by a center-left coalition , which ruled until 2010. Chile is a developing country with a high-income economy and is one of the most economically and socially stable nations in South America. Chile also performs well in the region in terms of sustainability of the state and democratic development. Chile is a founding member of the United Nations , the Community of Latin American and Caribbean States (CELAC), and
19043-608: Was succeeded in 2000 by Socialist Ricardo Lagos , who won the presidency in an unprecedented runoff election against Joaquín Lavín of the rightist Alliance for Chile . In January 2006, Chileans elected their first female president, Michelle Bachelet Jeria , of the Socialist Party, defeating Sebastián Piñera , of the National Renewal party, extending the Concertación governance for another four years. In January 2010, Chileans elected Sebastián Piñera as
19182-536: Was the head of the Council of Rapanui. The Rapa Nui elders ceded sovereignty, without renouncing their titles as chiefs, the ownership of their lands, the validity of their culture and traditions and on equal terms. The Rapa Nui sold nothing, they were integrated in equal conditions to Chile. The 1891 Chilean Civil War brought about a redistribution of power between the President and Congress, and Chile established
19321-439: Was very heavily hunted in the 18th and 19th centuries for its pelt by seal hunters from the United States and the United Kingdom. Leopard seals are apex predators in the Antarctic ecosystem and migrate across the Southern Ocean in search of food. There are approximately 40 bird species that breed on or close to Antarctica, including species of petrels , penguins , cormorants , and gulls . Various other bird species visit
