Key Points:

Background and Causes:

• Conflict Period: The War of the Pacific spanned from 1879 to 1884, pitting Chile against the allied forces of Peru and Bolivia.
• Resource at Stake: Control over nitrate and mineral deposits in the Atacama Desert, vital for fertilizers and explosives, drove the conflict.
• Economic Interests: Nitrate mining, initially dominant in Peru’s Tarapacá region, expanded to Bolivia’s Atacama in the 1860s, led by Chilean and British companies.
• Trade Routes: The war was also about securing Pacific trade routes and defining national borders.
• Preceding Conflicts: Earlier regional disputes, like the War of the Confederation (1836-1839) and the Spanish-South American War (1864-1866), set the stage for this rivalry.

Key Events:

• Outbreak: Began in 1879 over disputes in the nitrate-rich Atacama Desert.
• Major Battles:
• • Battles of San Juan and Chorrillos (January 13, 1881) and Miraflores (January 15, 1881) were brutal, leading to Chilean occupation of Lima.
  • Peruvian forces lost nearly a third of their troops in these engagements.
