Chile's Major Wars: Pacific, World Wars, and Spanish-American

Chile's significant conflicts:

• War of the Pacific (1879–1884): vs. Peru-Bolivia alliance; won nitrate-rich Atacama territories (Antofagasta, Tarapacá, Arica, Tacna); became regional power.
• World Wars I & II: Neutral but supplied Allies (nitrates, copper); economy boomed from demand.
• Spanish-American War (1898): Supported US logistically; strengthened US-Chile ties, cemented Latin American leadership role.

No major wars since 1945; focuses on diplomacy, UN peacekeeping, regional integration (Pacific Alliance).
