War of the Pacific

South American war (1879–1884) involving Chile against Peru and Bolivia

The War of the Pacific (or Saltpeter War) took place from 1879-1883. It grew out of a dispute between Bolivia and Peru against Chile over control of a part of the Pacific coast. The disputed area was part of the Atacama Desert that lies between the 23rd and 26th parallels. The territory contained valuable mineral resources, mainly potassium nitrate, which were exploited by Chilean companies and British interests. The Bolivian government decided to increase taxes to take advantage of the increasing income of the region, which led to a commercial dispute.

Boundary changes as a result of the war

The result of the war was that Bolivia lost its access to the ocean, and became landlocked.
