The territory of Chile has been populated since at least 3000 BCE. By the 16th century, Spanish conquistadors began to colonize the region of present-day Chile, and the territory was a colony between 1540 and 1818, when it gained independence from Spain. The country's economic development was successively marked by the export of first agricultural produce, then saltpeter and later copper. The wealth of raw materials led to an economic upturn, but also led to dependency, and even wars with neighboring states. Chile was governed during most of its first 150 years of independence by different forms of restricted government, where the electorate was carefully vetted and controlled by an elite.

Failure to address the economic and social increases and increasing political awareness of the less-affluent population, as well as indirect intervention and economic funding to the main political groups by the CIA, as part of the Cold War, led to a political polarization under Socialist President Salvador Allende. This in turn resulted in the 1973 coup d'état and the military dictatorship of General Augusto Pinochet, whose subsequent 17-year regime was responsible for numerous human rights violations and deep market-oriented economic reforms that modernized Chile and improved the population's quality of life. In 1990, Chile made a peaceful transition to democracy, initiating a succession of democratic governments.
Early history
About 10,000 years ago, migrating Native Americans settled in the fertile valleys and coastal areas of what is present-day Chile. Pre-Hispanic Chile was home to over a dozen different Amerindian societies. The current prevalent theories are that the initial arrival of humans to the continent took place either along the Pacific coast southwards in a rather rapid expansion long preceding the Clovis culture, or even trans-Pacific migration. These theories are backed by findings in the Monte Verde archaeological site, which predates the Clovis site by thousands of years. Specific early human settlement sites from the very early human habitation in Chile include the Cueva del Milodon and the Pali Aike Crater's lava tube.
Despite such diversity, it is possible to classify the indigenous people into three major cultural groups: the northern people, who developed rich handicrafts and were influenced by pre-Incan cultures; the Araucanian culture, who inhabited the area between the river Choapa and the island of Chiloé, and lived primarily off agriculture; and the Patagonian culture composed of various nomadic tribes, who supported themselves through fishing and hunting . No elaborate, centralized, sedentary civilization reigned supreme.
