Saltpeter war
From the Simple English Wikipedia, the free encyclopedia that anyone can change
The War of the Pacific or saltpeter war grew out of a dispute between Chile and Bolivia over control of a part of the Atacama desert that lies between the 23rd and 26th parallels on the Pacific coast. The territory contained valuable mineral resources 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.
