Lore & Background

The territory of Antofagasta was part of the Viceroyalty of the Río de la Plata and later Bolivia until the Boundary Treaty of 1866. The area was disputed between Chile and Bolivia until that treaty, which established a demarcation line between Chile and Bolivia without transferring sovereignty. On 18 September 1866, José Santos Ossa and Francisco Puelma achieved the award of the concession of nitrate lands, leading to the formation of the Sociedad Exploradora del Desierto de Atacama. On 8 May 1872, Antofagasta was designated by the Bolivian Government as Puerto Mayor, opening trade worldwide. In 1873, the Compañía de Salitres y Ferrocarril de Antofagasta, a Chilean mining company, signed a contract with the government of Bolivia removing taxes for 15 years, but this contract was not ratified by the Bolivian Congress.

Reader's Guide

Antofagasta's significance stems from its role as a port and service hub for one of Chile's major mining areas. Historically important for silver and saltpeter mining, since the mid-19th century copper mining has been the most important activity, fueling growth in construction, retail, and population until the end of the 2000s commodities boom in 2013. Since the 2010s, it has also become a service hub for lithium mining. The city's capture by Chile on 14 February 1879 triggered the War of the Pacific, and its sovereignty was formalized by the 1904 Treaty of Peace and Friendship. Antofagasta is the seat of one of Chile's three environmental courts and is a university city, home to the Catholic University of the North and the University of Antofagasta. In 2012, it had the highest GDP per capita in Chile at US$37,000 and ranked third in the Human Development Index. The city's climate is a cold desert climate (Köppen BWk) with extreme aridity, receiving less than 0.1 mm of rainfall annually, making it the world's driest town. However, sporadic heavy rainfall has caused mudslides, notably in 1991, which devastated much of the city.
