Chile, officially the Republic of Chile, is a country in western South America. It occupies a long, narrow strip of land between the Andes to the east and the Pacific Ocean to the west. Chile covers an area of 756,096 square kilometres and has a population of 17.5 million as of 2017. The capital and largest city is Santiago and the national language is Spanish.
Chile borders Peru to the north, Bolivia to the northeast, Argentina to the east, and the Drake Passage in the far south. Chilean territory includes the Pacific islands of Juan Fernández, Salas y Gómez, Desventuradas, and Easter Island in Oceania. Chile also claims about 1,250,000 square kilometres of Antarctica under the Chilean Antarctic Territory.
Spain conquered and colonized the region in the mid-16th century, replacing Inca rule, but failing to conquer the independent Mapuche who inhabited what is now south-central Chile. After declaring independence from Spain in 1818, Chile emerged in the 1830s as a relatively stable authoritarian republic.
