The War of the Pacific, spanning from 1879 to 1884, was a pivotal conflict in South American history, involving Chile against the allied forces of Peru and Bolivia. This war was primarily driven by disputes over valuable territories rich in mineral resources, particularly sodium nitrate, in the Atacama Desert region.
Causes of the War
The immediate catalyst for the war was a taxation conflict between Bolivia and Chile. In 1878, Bolivia imposed a new tax on the Chilean-owned Antofagasta Nitrate & Railway Company, violating a prior treaty that prohibited such increases. When the company refused to pay, Bolivia seized its property, prompting Chile to occupy the Bolivian port city of Antofagasta on February 14, 1879. Peru, bound by a secret mutual defense treaty with Bolivia, was drawn into the conflict after unsuccessful mediation efforts, leading Chile to declare war on both nations on April 5, 1879.
Major Campaigns and Battles
The war comprised several significant campaigns:
-
Naval Campaign: Control of sea routes was crucial due to the challenging desert terrain. Early naval engagements included the Battle of Iquique on May 21, 1879, where the Peruvian ironclad Huáscar sank the Chilean corvette Esmeralda. However, Chilean forces later captured the Huáscar at the Battle of Angamos on October 8, 1879, securing naval supremacy.
-
Land Campaigns: With control of the sea, Chile launched amphibious assaults, notably capturing the Peruvian province of Tarapacá and the Bolivian province of Litoral. Key battles included the Battle of Pisagua (November 2, 1879) and the Battle of Tacna (May 26, 1880), after which Bolivia effectively withdrew from the war. Chilean forces continued northward, occupying Lima in January 1881.
Outcomes and Consequences
The war concluded with the Treaty of Ancón in 1883, in which Peru ceded the province of Tarapacá to Chile. Subsequent agreements resulted in Chile’s annexation of additional territories, leaving Bolivia landlocked—a status that persists today. These territorial changes significantly altered the geopolitical landscape of the region and had lasting economic and political impacts on the involved nations.
Legacy
The War of the Pacific reshaped national boundaries and influenced the economic trajectories of Chile, Peru, and Bolivia. Chile’s acquisition of resource-rich territories bolstered its economy, while Bolivia’s loss of coastal access has remained a central issue in its foreign policy. The conflict’s legacy continues to affect diplomatic relations in South America.
