Chile, officially the Republic of Chile, is a country in the Southern Cone of southwestern South America. It is the southernmost country in the world and the closest to Antarctica, extending along a narrow strip of land between the Andes Mountains and the Pacific Ocean. According to the 2024 census, Chile had an enumerated population of 18.5 million. The country covers a territorial area of 756,102 square kilometers (291,933 sq mi), sharing borders with Peru to the north, Bolivia to the northeast, Argentina to the east, and the Drake Passage to the south. It also administers 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 is Santiago, and the official and national language is Spanish.
Spain conquered and colonized the region in the mid-16th century, replacing Inca rule; however, they failed to conquer the autonomous tribal Mapuche people who inhabited what is now south-central Chile. Chile emerged as a relatively stable authoritarian republic in the 1830s after its 1818 declaration of independence from Spain. During the 19th century, Chile experienced significant economic and territorial growth, putting an end to Mapuche resistance in the 1880s and gaining its current northern territory in the War of the Pacific (1879–83) by defeating Peru and Bolivia.
In the 20th century, until the 1970s, Chile underwent a process of democratization and experienced rapid population growth and urbanization, while relying increasingly on exports from copper mining to support its economy. During the 1960s and 1970s, the country was marked by severe left-right political polarization and turmoil, which culminated in the 11 September 1973 coup d'état, with support from the United States, that overthrew Salvador Allende's democratically elected left-wing government. This was followed by a 16-and-a-half-year right-wing military dictatorship led by Augusto Pinochet, during which the 1980 Constitution was enacted, along with numerous political and economic reforms, and which was marked by widespread human rights violations, including more than 3,000 deaths and disappearances. The regime ended in 1990, following a referendum in 1988, and was succeeded by a center-left coalition, which ruled until 2010.
Chile is 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 the Pacific Alliance, and joined the OECD in 2010.
There are various theories about the origin of the word Chile. According to 17th-century Spanish chronicler Diego de Rosales, the Incas called the valley of the Aconcagua Chili by corruption of the name of a Picunche tribal chief (cacique) called Tili, who ruled the area at the time of the Incan conquest in the 15th century. Another theory points to 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 the Earth". Another origin attributed to chilli is the onomatopoeic cheele-cheele—the Mapuche imitation of the warble of a bird locally known as trile.
The Spanish conquistadors heard about this name from the Incas, and the few survivors of Diego de Almagro's first Spanish expedition south from Peru in 1535–36 called themselves the "men of Chilli". Ultimately, Almagro is credited with 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 far back as 18,500 years ago. About 10,000 years ago, migrating Indigenous peoples settled in fertile valleys and coastal areas of what is present-day Chile. Settlement sites from very early human habitation include Monte Verde, Cueva del Milodón and the Pali-Aike Crater's lava tube.
The Incas briefly extended their empire into what is now northern Chile, but the Mapuche (or "Araucanians", as they were known by the Spaniards) successfully resisted many attempts by the Inca Empire to subjugate them, despite their lack of state organization, fighting against the Sapa Inca Topa Inca Yupanqui and his army; the result of the bloody three-day Battle of the Maule was that the Inca conquest of Chilean territory ended at the Maule river.
The Mapuche are the largest Indigenous group in South America, with a population of nearly two million, primarily residing in the Central Valley of Chile, with a smaller population in Argentina. They were referred to by Spanish colonizers as Araucanians and historically they were considered one of the three main groups, the Picunche, the Mapuche, and the Huiliche, which today all identify as Mapuche. Before European contact, Mapuche society consisted mainly of scattered farming villages which were primarily led by a chief whose authority was limited to his own village. The Mapuche are notable for their long and determined resistance to foreign domination resisting both the Incan empire and Spanish colonial forces. During the 16th century, the Mapuche reorganized made alliances, and formed a resistance against the Spanish and later Chilean expansion. They maintained a level of autonomy until the late 19th century when Chile subdued their territory. Despite colonization and loss, the Mapuche have retained many aspects of their culture, identity, and tradition to this day.
In 1520, while attempting to circumnavigate the globe, Ferdinand Magellan discovered the southern passage now named after him (the Strait of Magellan) thus becoming the first European to set foot on what is now Chile. The next Europeans to reach Chile were Diego de Almagro and his band of Spanish conquistadors, who came from Peru in 1535 seeking gold. The Spanish encountered various cultures that supported themselves principally through slash-and-burn agriculture and hunting.
The conquest of Chile began in earnest in 1540 and was carried out by Pedro de Valdivia, one of Francisco Pizarro's lieutenants, who founded 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 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 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 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.
