What is the main bone of contention in the War of the Pacific?

The main bone of contention in the War of the Pacific was the Atacama Desert. This conflict occurred from 1879 to 1884, primarily involving Chile, Bolivia, and Peru. The Atacama Desert is significant due to its rich mineral resources, particularly nitrates, which were economically valuable for fertilizers and explosives during that time.

The strategic control of this region was crucial for trade and economic stability. Bolivia lost its coastal territory to Chile through the war, leading to its current status as a landlocked country and intensifying the rivalry over access to the Pacific Ocean. The Atacama Desert's harsh environment and valuable resources made it a focal point of national interests and national pride, shaping the historical and geopolitical landscape of South America.
