About South America

South America’s military history is defined by colonial conquest, revolutionary wars for independence, border conflicts, and internal insurgencies. Indigenous civilizations such as the Inca Empire maintained large, organized military forces before European contact. The 16th century brought violent colonization by Spain and Portugal, which suppressed native resistance and shaped the continent’s political divisions. In the early 19th century, revolutionary leaders like Simón Bolívar and José de San Martín spearheaded independence movements, leading to wars that dissolved colonial rule and established the modern nation-states. Post-independence, the continent experienced numerous border disputes, civil wars, and military coups. Major conflicts include the War of the Triple Alliance (1864–1870), the War of the Pacific (1879–1884), and the Chaco War (1932–1935). During the Cold War, South America became a battleground for ideological influence, with the U.S. supporting anti-communist regimes and leftist guerrilla movements gaining ground in countries like Colombia and Peru. Military dictatorships ruled much of the region through the 20th century, often marked by repression and human rights violations. Today, while large-scale wars are rare, South American militaries remain active in peacekeeping, anti-narcotics operations, and disaster response. Regional cooperation through organizations like UNASUR and the South American Defense Council continues to evolve. The continent's military past reflects a struggle for self-determination, identity, and security amid political and social change.
