Flag of the Republic of Chile

Chile, officially the Republic of Chile, is a country in western South America. It is the southernmost country in the world and the closest to Antarctica, stretching along a narrow strip of land between the Andes Mountains and the Pacific Ocean. Chile had a population of 17.5 million as of the latest census in 2017 and has a territorial area of 756,102 km2 (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. The country also controls several Pacific islands, including Juan Fernández, Isla Salas y Gómez, Desventuradas, and Easter Island, and claims about 1,250,000 km2 (480,000 sq mi) of Antarctica as the Chilean Antarctic Territory. The capital and largest city of Chile is Santiago, and the national language is Spanish. Spain conquered and colonised the region in the mid-16th century, replacing Inca rule, but 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 their 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, up until the 1970s, Chile underwent a process of democratisation and experienced rapid population growth and urbanisation, 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 polarisation 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, in which the 1980 Chilean Constitution was made with the consultancy of the Ortúzar Commission as well as several political and economic reforms, and resulted in more than 3,000 deaths or disappearances. The regime ended in 1990, following a referendum in 1988, whereafter Chile has been as democracy. 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.
