About 10,000 years ago, migrating Indians settled in fertile valleys and along the coast of what is now Chile. The Incas briefly extended their empire into what is now northern Chile, but the area's remoteness prevented extensive settlement. The first Europeans to arrive in Chile were Diego de Almagro and his band of Spanish conquistadors in 1541, which came from Peru in 1535 seeking gold.

The Spanish encountered hundreds of thousands of Indians from various cultures in the area that modern Chile now occupies. These cultures supported themselves principally through slash-and-burn agriculture and hunting. The conquest of Chile was carried out in 1550 by Pedro de Valdivia, one of Francisco Pizarro's lieutenants. 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 Viceroyalty of Peru.

The drive for independence from Spain was precipitated by usurpation of the Spanish throne by Napoleon's brother Joseph. A national junta in the name of Ferdinand--heir to the deposed king--was formed on September 18, 1810. The junta proclaimed Chile an autonomous republic within the Spanish monarchy. A movement for total independence soon won a wide following. Spanish attempts to reimpose arbitrary rule during what was called the Reconquista led to a prolonged struggle.

Intermittent warfare continued until 1817, when an army led by Bernardo O'Higgins, Chile's most renowned patriot, and José San Martín, hero of Argentine independence, crossed the Andes into Chile and defeated the royalists. On February 12, 1818, Chile was proclaimed independent.

Allende's proposal also included the nationalization of U.S. interests in Chile's major copper mines. Elected with only 36% of the vote and by a plurality of only 36,000 votes, Allende never enjoyed majority support in the Chilean Congress or broad popular support. Domestic production declined; severe shortages of consumer goods, food, and manufactured products were widespread; and inflation reached 1,000% per annum. Mass demonstrations, recurring strikes, violence by both government supporters and opponents, and widespread rural unrest ensued in response to the general deterioration of the economy. By 1973, Chilean society had split into two hostile camps.

A military coup overthrew Allende on September 11, 1973. As the armed Forces bombarded the presidential palace, Allende reportedly committed suicide. A military government, led by General Augusto Pinochet, took over control of the country. The first years of the regime were marked by serious human rights violations. A new constitution was approved by a plebiscite on September 11, 1980, and General Pinochet became President of the Republic for an 8-year term. In its later years, the regime gradually permitted greater freedom of assembly, speech, and association, to include trade union activity. In contrast to its authoritarian political rule, the military government pursued decidedly laissez-faire economic policies. During its 16 years in power, Chile moved away from economic statism toward a largely free market economy that fostered an increase in domestic and foreign private investment.

In a plebiscite on October 5, 1988, General Pinochet was denied a second 8-year term as president. Chileans voted for elections to choose a new president and the majority of members of a two-chamber congress. On December 14, 1989, Christian Democrat Patricio Aylwin, the candidate of a coalition of 17 political parties called the Concertacion, received an absolute majority of votes. President Aylwin served from 1990 to 1994.
