Chile became independent from Spain on 18 September 1818. In the 1925 Constitution, Chile assumed the character of a western-style democracy. During the following decades, Chile enjoyed a certain amount of political and social stability until 11 September 1973, when the left-wing government of Salvador Allende (in power since 1970) was toppled by a coup supported by the United States.
The military junta of General Augusto Pinochet closed down Parliament, dissolved the political parties, abolished the Constitution, abolished civil liberties and proceeded to install a regime based on ruthless repression. The first signs of a return to democracy appeared in 1980, when a popular vote approved a new Constitution (which came into force on 11 March 1981 and was altered again in a referendum on 30 July 1989). On 8 October 1988, the committee governing elections rejected General Pinochet’s bid to stay in power for another eight years and at the subsequent 1989 elections the candidate for the united opposition, Christian Democrat Patricio Aylwin, was elected President of the Republic, putting an end to the long authoritarian regime.
The President of the Republic, who is elected by direct suffrage, is also head of the government.
The new Constitution, which came into force on 17 September 2005, reduced the presidential mandate from six years to four; it cannot be renewed. Legislative power lies in the hands of the National Congress, which comprises the Chamber of Deputies (155 members, elected for four years) and the Senate (43 members, who stay in office for eight years, half being renewed every four years). In 2015 an electoral reform was approved, increasing the representation of lesser parties and which will bring the number of members of the House to 150 and those of the Senate to 50. The Congress has been headquartered in Valparaíso since 1987.

Defence.
Military service is almost completely voluntary. It lasts for one year in the army and for 22 months in the navy and the air force.

Justice.
The legal system is based on Spanish Law.
Divorce became legal in Chile in 2004.

Economic situation.
The economy’s growth, one of the most developed in South America, is supported above all by revenue from exports, particularly copper, which are partially stored in a sovereign fund used to finance the deficit in difficult periods. The role of foreign investments is significant, which offset part of the deficit of the current accounts. The tax burden was redistributed in order to weigh primarily on higher incomes and companies in an attempt to reduce the substantial social disparity.

Primary sector
Agriculture.
Most of the large commercial estates, which constitute about three-quarters of the cultivated land and produce mainly for export, lie in the centre of Chile. In the north, smallholdings predominate, based on subsistence farming (growing legumes and cereals).
The most important sectors for export are fruit and vegetables (grapes, apples, kiwifruit, pears, plums, peaches and tomatoes), sugar beet and wine, a sector where quality is constantly on the increase. Although cereal crops are very important (wheat, barley, oats, maize and rice), harvests are not enough to meet the country’s requirements.
Forests.
Forests are located in the south of the country and include several southern species of beech, including the Nothofagus obliqua and some conifers, e.g. the prized larch (Fitzroya cupressoides), as well as poplars and eucalyptus.
Livestock.
Livestock farming is practised extensively; llama and alpaca are kept on the plateaux for their highly-prized wool.
Fishing.
Fishing plays a vital role in the Chilean economy and fuels a fish oil and fish-flour industry. Anchovies, sardines, cod, mackerel and seafood are among the species fished the most. Fish farming produces salmon, sole, trout and shellfish.

Secondary sector
Minerals.
The main mineral produced is copper (with deposits at El Salvador, El Teniente, Chuquicamata and Andina, which have smelting and refining plants close by). Copper-processing generates various by-products including arsenic, molybdenum, rhenium and selenium.
Other important minerals are gold (deposits at Andacollo and Marga Marga), silver (at La Serena, Taltal and Caracoles) and sulfur (on the slopes of Aucanquilcha). Molybdenum is mined at Valparaíso, Vallenar, Santiago and Coquimbo.
Iron is mined at El Laco (Antofagasta), Carmen, Las Adrianitas, Cerro Imán, Bandurrias, Boquerón-Chañar, El Algarrobo (Atacama), El Pleito, El Romeral and El Dorado (Coquimbo). There are significant lithium reserves (Salar de Atacama). Deposits of nitrates (Chile saltpetre) are found in northern Chile (at Iquique, Antofagasta, Tocopilla and Taltal). By-products of sodium nitrate include borax (at Ascotán, Chilcaya and Pedernal) and iodine. Oil is extracted in the south of the country (at Cerro Manantiales in Tierra del Fuego). A 72-km pipeline long takes the crude oil to the port at Caleta Clarencia. Refineries are in operation at Concón, near Valparaíso, Hualpén, near Concepción, and at San Gregorio, in Patagonia. There are natural gas reserves at Pampa Larga, Punta Delgada and Chanarcillo, but most of the demand is satisfied by import. Coal is mined in the provinces of Arauco and Magallanes.
Energy and industry.
Much of the electrical energy produced in Chile comes from hydro-electric schemes (power-plants on the rivers Biobío, Melado, Raja, Rapel and near Colbún Lake). Re-gasification plants are located at Mejillones and Quintero. In particular, industrial activities are linked to the processing of the raw materials obtained from mining, farming and forestry. In addition to copper-working (at Chuquicamata, El Teniente-Caletones, Potrerillos, El Salvador, Paipote, Las Ventanas, Chagres and Antofagasta), iron and steel is important (at Huachipato, Talcahuano and Corral). The chemical industry produces caustic soda, sulfuric acid and nitrogenous fertilizers. At Calama explosives are made for the mining industry. At Santiago there are pharmaceutical plants.
One of the main segments of the economy is textiles, using Chilean wool (at Tomé, Concepción, Valparaíso and Santiago) and imported cotton. There are rayon production plants at Llolleo and Quillota. Synthetic fibres are produced at San Joaquín and Santiago. There are tanneries and footwear factories at Valdivia, Santiago, Valparaíso, Concepción and Chillán. In the food-processing segment, the most important sectors are fish, frozen meat and conserves (at Punta Arenas, Ancud, Osorno, Valparaíso, Coquimbo, Antofagasta and Iquique), as well as sugar refining (at Chillán, Curicó, Linares, Los Ángeles) and beer. The engineering and electro-mechanical industry consists almost exclusively of vehicle assembly workshops (at Arica). The paper industry is concentrated at Santiago, Valdivia and Talca. Cigarettes, tyres and cement are also produced (near Santiago, Valparaíso, Concepción, and at San Antonio, Curicó, Puerto Montt).

Tertiary sector
Foreign trade.
Chile’s main trading partners are China, the USA, Brazil, Japan, South Korea and Argentina. Chile has signed free-trade agreements with the USA, China and many other countries and international organizations, including the EU and Mercosur.

Main exports (M US$ - 2017) refined copper 17 799, copper ores 17 404, fresh and preserved fruit 6 033, fresh and preserved fish 5 585, wood pulp 2 614, timber 2 233, chemicals 2 116, wine 2 018, molybdenum 986, iron ores 983, gold and silver 932, meat 813, vehicles and parts thereof 798, machinery 673, fruit & vegetable juices and preserves 610, fertilizers 565, iron and steel 535, paper 480, plastics 461, petroleum products 445, electric and electronic equipment 412

Finance
and banking.
The Banco Central de Chile acts as Chile’s central bank. The main bank is the Banco del Estado, which is state-owned. There is a stock exchange at Santiago.

Tourism. The main attractions for tourists are the Andean ski resorts, its beaches, Tierra del Fuego and Easter Island.

Transport.
The most important road in Chile is the Pan-American Highway (3369 km) between Arica and Puerto Montt. The Trans-Andean Highway, which connects Chile to Argentina, is very important for trade.
The railway network is based on Santiago; four lines cross the Andes (to Argentina and Bolivia) but are little used.
The port and airport networks are highly developed.

Education and research.
With the approval of a law in 2013, pre-school education became mandatory and free of charge for children over 2 years, bringing the overall duration of mandatory education to 13 years.

Social security.
The social security system (which dates from 1981) provides free hospital care for all citizens over the age of 60. The pension system was privatized in 1980 and reformed in 2008 to cover more people.
