Chile , officially Republic of Chile, Country, southwestern South America. Area: 291,929 sq mi (756,096 sq km). Population: (2024 est.) 20,095,000. Capital: Santiago. About three-fourths of Chileans are mestizos; most of the rest are of European ancestry or Aracanian (Mapuche) Indians. The indigenous peoples before Spanish colonization included the Diaguita, Picunche, Mapuche, Huilliche, Pehunche, and Cunco Indians. Spanish colonists arrived during the 16th–17th centuries, followed by Basque settlers in the 18th century. A relatively homogeneous population of mestizos has developed. Language: Spanish (official). Religion: Christianity (predominantly Roman Catholic; also Protestant, other Christians). Currency: Chilean peso. Chile is noteworthy for its unique topography: it is a long, narrow country lying between the Andes Mountains and the Pacific Ocean. From north to south it is about 2,700 mi (4,300 km) long and nowhere more than 217 mi (349 km) wide. The north has an arid plateau, the Atacama Desert, and contains several peaks above 16,000 ft (4,900 m), but most of the highest peaks are on the borders with Bolivia and Argentina. The rivers, including the Bío-Bío, are limited in size. There are many lakes, including Lake Llanquihue. The extreme southern coast is marked by many inlets, islands, and archipelagoes; the western half of Tierra del Fuego (including the island on which Cape Horn is located) is in Chilean territory, as are small islets of Juan Fernández and Easter Island. The country is periodically beset by violent earthquakes and tsunamis that originate along major faults of the ocean floor. In 1960 Chile was struck by a magnitude-9.5 earthquake, the largest ever recorded. A magnitude-8.8 earthquake caused extensive damage in 2010. Chile has a partially developed free-market economy based mainly on mining and manufacturing. It is a multiparty republic with two legislative houses; its head of state and government is the president. Originally inhabited by native peoples, including the Mapuche, the area was invaded by the Spanish in 1536. A settlement begun at Santiago in 1541 was governed under the Viceroyalty of Peru but became a separate captaincy general in 1778. Its people revolted against Spanish rule in 1810; independence was finally assured by the victory of Argentine and Chilean forces under José de San Martin at the Battle of Chacabuco in 1817. The area was governed by Chilean Gen. Bernardo O’Higgins until 1823. In the War of the Pacific (1879–83) against Peru and Bolivia, Chile won the rich nitrate fields on the coast of Bolivia, effectively severing that country’s access to the coast. Chile remained neutral in World War I (1914–18) and for most of World War II (1939–45), though in 1942 it joined other Latin American countries in declaring war on the Axis. In 1970 Salvador Allende was elected president, becoming the first avowed Marxist to be elected head of state in Latin America. Following economic upheaval, he was overthrown in 1973 in a coup led by Augusto Pinochet, whose military regime harshly suppressed internal opposition. A national referendum in 1988 and elections the following year removed Pinochet from power and returned the country to democratic rule. Chile’s economy maintained steady growth through most of the 1990s and in the early 21st century remained one of the strongest in Latin America.
