Once claimed by Bolivia following the Spanish American wars of independence, Antofagasta was captured by Chile on 14 February 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 mining 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 skyline development until the end of the 2000s commodities boom in 2013.

The territory was disputed between Chile and Bolivia until the signing of the Boundary Treaty of 1866.
On 18 September 1866, José Santos Ossa and Francisco Puelma achieved the award of the concession of nitrate lands, following a request taken to the Bolivian government. The exploring of the Chilean miners found rich deposits of Chile saltpeter (nitratine) in the field of Salar del Carmen, to the east of the present Antofagasta. Agreed to form the " Sociedad Exploradora del Desierto de Atacama" (Explorer Society of Atacama Desert). After the formation of the company, began to fill with what was called " La Chimba".

On 27 November 1873, the "Compañía de Salitres y Ferrocarril de Antofagasta" (CSFA), a Chilean mining company, signed a contract with the government of Bolivia, in which taxes were removed from mineral exploitation for 15 years. This contract was not ratified by the Congress of Bolivia, which was then analyzed negotiations with Chile.
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.
According to the Bolivian version of events, the contract with the saltpeter company was incomplete so the congress, to approve the contract, decided to enforce a tax of 10 cents, which did not violate the treaty of 1874, since the contract was not yet in force at that date. 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.
