Антофагаста: История, экономика и роль в Тихоокеанской войне.

Antofagasta (antofaˈɣasta) is a port city in northern Chile, about north of Santiago. It is the capital of Antofagasta Province and Antofagasta Region. According to the 2015 census, the city has a population of 402,669. After the Spanish American wars of independence, Bolivia claimed Antofagasta as part of its territory. Antofagasta was captured by Chile on February 14, 1879, triggering the War of the Pacific (1879–83). Chilean sovereignty was officially recognised by Bolivia under the terms of the 1904 Treaty of Peace and Friendship. The city of Antofagasta is closely linked to mining activity, being a port and the chief service hub for one of Chile's major mining areas. While silver and saltpeter mining have been historically important for Antofagasta, since the mid 19th century copper mining is by far the most important mining activity for Antofagasta fueling a steady growth in the areas of construction, retail, hotel accommodations, population growth, and a remarkable skyline development until the end of the 2000s commodities boom in 2013. Since the 2010s Antofagasta is also a service hub for lithium mining. Antofagasta has the highest GDP per capita of Chile, US$37,000 and the 3rd place for Human Development Index just after Metropolitana de Santiago Region and Magallanes and Antártica Chilena Region.

In 1873, Bolivia signed a secret treaty of defensive alliance with Peru. This would be used as an argument 5 years later in Chile, when it unleashed the War of the Pacific. The secret alliance forbade Bolivia from signing a border treaty with Chile, without consulting with Peru. However, in 1874 Chile and Bolivia signed a border treaty, which replaced the previous treaty of 1866. One of its points was not to impose new taxes on individuals, industries and Chilean capital for 25 years. For Bolivia, the contract of 1873 between the government and CSFA was not yet in force, because, according to the Bolivian constitution, all contracts with the Bolivian government had to be approved by the congress. Bolivia suspended the tax in deference to the government of Chile, but following a note from the Chilean foreign minister, it reactivated the tax law, then cancelled and closed the "Compañía de Salitres". Faced with a looming conflict with Chile, Bolivia decided to claim support under the agreement signed with Peru, and the treaty became effective with the Chilean occupation of Antofagasta, on 14 February 1879. According to the Chilean version of events, the tax of 10 cents violated the treaty of 1874 since according to this, new taxes should not have been imposed on Chilean companies operating in Bolivia. At the breaking of the boundary treaty by Bolivia, and the cancellation of the contract of the CSFA, Chile seized Antofagasta, then in Bolivian territory, whose sovereignty had been ratified before 1866. After the war, a pact of truce was signed between Bolivia and Chile in 1884, which stated that the territory between the Loa River and parallel 23 would be under the administration of Chile, while Bolivia would be allowed access to the ports of Arica and Antofagasta.

The Treaty of Peace and Friendship between Chile and Bolivia, signed on 20 October 1904, and promulgated on 21 March 1905, established in perpetuity border between Chile and Bolivia. In 1912, the British community (La Colonia Britanica) erected a clock tower, replicating Big Ben, in Plaza Colón to celebrate the republic's centenary. In 1937, the Municipality of Antofagasta made a national call for the composition of Antofagasta's anthem. Antonio Rendic, famous physician and poet of the city, and Juan Bautista Quagliotto, musician, claimed the right to compose the lyrics and music, respectively. In 1956, the Universidad del Norte (now the Catholic University of the North) was founded, due to support from the Catholic University of Valparaíso. On 9 October, of the same year began the negotiations for the creation of the "Centro Universitario Zona Norte" (University Center North Zone), part of the University of Chile. In 1968, the Antofagasta center of the University of Chile was inaugurated, after a university reform agreement which meant the autonomy of the University Center North Zone. On 18 June 1991, a mudslide devastated much of the city, undermining land, damaged 2,464 houses and destroyed 493 buildings. Material damage was estimated at $70,000,000. The disaster left 92 dead, 16 missing and about 20,000 homeless. On 30 July 1995, the city was hit by an earthquake measuring 7.3 on the Richter Scale, with an intensity VII to VIII on the Mercalli Scale. Although it took a toll of three deaths and a hundred injuries, structural damage was minor for the magnitude of the event.

The construction industry has had remarkable growth as seen in the many recently constructed tall buildings, the extension of the urban area to the north of the city, and different urban projects as the renovation of the entire Costanera Avenue, and walkways of the city center. In economic development, settled many retail chains and supermarkets as well as various high quality hotel chains, which promoted business tourism to attract capital and trading partners in mining and port activity. Similarly, the city was awarded the installation of the Casino Enjoy Antofagasta. In the municipal elections of 2008, the first female mayor of the city, Dra. Marcela Hernando, was elected, who retired from her political party to run as an independent. This allowed her to have diverse support from all sectors of the population of Antofagasta.

There are about fifteen streams that have watersheds with accumulation of sand and gravel. Within the broader watershed (hoya) are the "Hoya La Chimba", "Hoya Caracoles", "Hoya La Cadena", "Hoya La Negra" and "Hoya El Way". These watersheds and their streams (Quebrada), such as "Quebrada sin nombre", "Quebrada Baquedano", "Quebrada El Toro", "Quebrada El Carrizo" and "Quebrada Jardines del Sur", which helped cause the flood of 1991. The coastal edge of Antofagasta is rocky and steep, so there are no natural beaches, the majority being artificial. Just north of the city, natural beaches extend to the areas of "La Portada", "Las Losetas" and "La Rinconada". Within the water resources of the commune, there are different dry lakes (salar), among which include the Salar de Pajonales, Salar Mar Muerto, Salar Punta Negra and the Salar de Navidad.

As a commune, Antofagasta is a third level administrative division of Chile administered by a municipal council, headed by an alcalde who is directly elected every four years. As of 2021, the mayor is Jonathan Velásquez. Within the electoral divisions of Chile, Antofagasta is represented in the Chamber of Deputies by Marcela Hernando (PRSD) and Paulina Nuñez (RN) as part of the 4th electoral district, together with Mejillones, Sierra Gorda and Taltal. The commune is represented in the Senate by Pedro Araya (Progressive Convergence, 2014–2022) and Alejandro Guillier (Progressive Convergence, 2014–2022) as part of the 2nd senatorial constituency (Antofagasta Region).

In addition, the Municipality of Antofagasta has a number of municipal headquarters, which are entities created to meet and control certain community needs a more specific way.

Antofagasta's economic development is mainly based on copper mining and nonmetallic minerals such as nitrate and iodine. Antofagasta owns two major industrial areas; one is located outside the urban area known as Ciudad Empresarial La Negra, a complex of approximately 2,400 hectares. There are refinery furnace copper industries in addition to cement, lime and other products. The second industrial area is located in the north of the city, where they have installed multiple operating centers of different companies, mainly along the "Pedro Aguirre Cerda Avenue." Trade is concentrated mainly in the center of Antofagasta, around the Plaza Colón, where there are installed within the last 2 decades several national retail chains. Moreover, in different parts of the city have set up large supermarket chains like "Líder", "Tottus", "Unimarc", "Santa Isabel" and "Jumbo". Recently in 2006, were also installed, the national chain " Mall Plaza" in the coastal area and the "Casino Enjoy Antofagasta" in the south of the city.

Because of the important administrative position of Antofagasta in the region, the historical relationship with the mining sector, and the production of the 54% of copper at the national level. Events are held annually with the assistance of several mining countries of the world, and one of the most important is Exponor organized by the Asociación de Industriales Antofagasta, guild formed by the major copper producers in the region. Exponor is a show that promotes the gestation of chains, new business and exchanging knowledge and experiences among entrepreneurs from different countries of the world. This important trade fair generated a portfolio of U. S. $41,291 million (63.48% world total), for the period 2007–2015.

As of 2009, this city is considered the most expensive to live in Chile, next to Santiago and Punta Arenas.

The city has several public and private educational universities. Two major traditional universities, one that is public, University of Antofagasta, and other private, Catholic University of the North. Several private autonomous universities have been open since 2002. Previously, the now defunct "University José Santos Ossa" was the only private autonomous university in Antofagasta. Although the public schools are distributed almost uniformly throughout the city, the private schools operate mainly in the central and southern part of the city, where the wealthiest inhabitants reside. Only three private schools in the city are ranked among the top 100 schools in the country with the highest scores in the University Selection Test, which are The Antofagasta British School, "Hrvatska Skola San Esteban" and "Antofagasta International School".

The main land route connectivity in the province is Route 5 CH, which connects the city with the rest of the country and is part of the Panamerican Highway. This route connects to the city by Route CH 26 in the north of the city, and Route CH 28 to the south. In addition, the city is connected to the north of the country by Route 1 CH, a way that also allows access to Andrés Sabella Gálvez International Airport and the natural monument La Portada. Vehicular traffic is concentrated around the main avenues of the city due to the long and narrow shape of the urban area. The only avenue that crosses the city from north to south, corresponds to the coastal route known as Avenida Costanera, which is formed by the avenues Jaime Guzmán, Ejército, República de Croacia, Grecia, José Manuel Balmaceda, Aníbal Pinto, 7º de Línea and Edmundo Pérez Zujovic; these avenues provide access to places including Mall Plaza Antofagasta, the Campus Coloso of the University of Antofagasta, the city hall of the Municipality of Antofagasta.

Andrés Sabella Gálvez International Airport is the only airport in Antofagasta and is located in Cerro Moreno, north of the city. This site, despite being classified as International Airport, operates mostly as a terminal for national flights, with one international airline, LATAM Peru, flying to Lima. In this terminal three domestic airlines also operate, LATAM Chile, Principal Airlines and Sky Airlines.

The city has a port complex of seven docks, inaugurated by President Carlos Ibáñez del Campo on 14 February 1943 under the name of Puerto de Antofagasta, which consists of two terminals. Terminal 1, consists of the docks 1, 2 and 3, is multi operator and is managed by the "Empresa Portuaria Antofagasta" (EPA) since 1 July 1998. Terminal No. 2, composed of docks 4, 5, 6 and 7, monooperario type, which is managed and operated by the company "Antofagasta Terminal Internacional" (ATI) since 1 March 2003. Overall, this tourist (member of the Association of Cruise Ports Southern Cone) and commercial port, can operate the production of 5,000,000 tons of cargo. Escondida, the biggest private mining company in Chile, has a private port located in southern city, near Cerro Coloso.

The higher transportation consists of thirteen lines of minibuses, which correspond to buses with a capacity of fewer than thirty people. The public transport is within a tender and is known as TransAntofagasta. The public transport plan took effect officially on 28 November 2005, replacing the old bus service. The route of these buses finish in the Caleta Coloso (south end of the city) during the year, and during the summer come as far as Balneario Juan Lopez, which is out of town. The lower transport consists of taxis lines, corresponding to a black sedans that make their way through the urban area through fixed routes.

The most important railroad is the Ferrocarril de Antofagasta a Bolivia (FCAB) founded in 1888, during the economic boom of the saltpeter industry. In 1930, FCAB was acquired by Antofagasta PLC, which is part of the Quiñenco commercial group. Unlike other contemporary mining railways, FCAB survived the crash of the natural nitrate sector. It provides a variety of transportation services most notably, the transport of mining products and consumables such as copper cathodes and sulfuric acid via a long rail network that is connected to the Ferrocarril Andino de Bolivia, Ferronor (Chile), and Ferrocarril Belgrano in Argentina (Salta–Antofagasta railway). Its gauge is 1000.

Due to the accelerated urban and demographic growth of Antofagasta during 2000–2010, a commuter train using the current FCAB line is currently under review. The project aims to decongest vehicle traffic by linking the north and south of the city with a direct train line.
