War of the Pacific (Saltpeter War) (1879-1884)

The War of the Pacific (Spanish: Guerra del Pacífico), also known as the Saltpeter War (Spanish: Guerra del salitre) and by multiple other names, was a war between Chile and a Bolivian–Peruvian alliance from 1879 to 1884. Fought over Chilean claims on coastal Bolivian territory in the Atacama Desert, the war ended with a Chilean victory, which gained for the country a significant amount of resource-rich territory from Peru and Bolivia. The Chilean Army took Bolivia's nitrate-rich coastal region, and Peru was defeated by the Chilean Navy.
