History
People have lived around the oases of the Salar de Atacama for more than ten thousand years. The Atacameño, or Lickanantay, built villages such as Tulor, where round mud-walled houses date back some 2,500 years, traded llama caravans across the Andes, and came under Tiwanaku influence and then Inca rule; the stone fortress of Pukará de Quitor above San Pedro was built in the 12th century to defend the oases.
After independence, the coast north of about latitude 24° belonged to Bolivia, while Copiapó and the Atacama Region were Chilean silver country: the strike at Chañarcillo in 1832 made fortunes, and the Caldera–Copiapó railway of 1851 was one of the first in South America. When Bolivia raised taxes on a Chilean nitrate company in Antofagasta, Chile occupied the port in February 1879, starting the War of the Pacific. Bolivia ceded the coast by treaty in 1904, leaving it landlocked, and in 2018 the International Court of Justice ruled that Chile has no obligation to negotiate the sea access Bolivia seeks.
The 20th century belonged to mining. Nitrate towns such as Chacabuco and María Elena rose on the pampa, and the vast copper pit of Chuquicamata near Calama was nationalised in 1971. Chacabuco was used as a detention camp after the 1973 coup, and a military squad known as the Caravan of Death executed prisoners at Calama and Antofagasta that October. In 2010 the rescue of 33 miners trapped for 69 days in the San José mine near Copiapó was followed around the world.
