South America
The Andes mountain range stretches along the western edge of South America, forming the longest uninterrupted mountain chain on Earth. Its highest peak, Aconcagua in Argentina, reaches 6,961 meters above sea level. This massive geological feature dominates the continent's western geography and influences weather patterns across multiple nations. The Amazon River flows through the heart of the continent, carrying more water than any other river system globally. It drains an area larger than all but one country in the world, creating a vast network of tributaries that support immense biodiversity. In Venezuela, Angel Falls drops 979 meters from the tabletop mountain of Mount Roraima, making it the world's highest uninterrupted waterfall. The Atacama Desert in northern Chile stands as the driest non-polar place on Earth, receiving less than one millimeter of rain annually in some areas. Meanwhile, López de Micay in Colombia records the highest rainfall totals anywhere on the planet, with over 13,000 millimeters falling each year. Lake Titicaca sits at 3,812 meters elevation between Peru and Bolivia, holding the title of the highest commercially navigable lake in existence.
Human presence in South America dates back at least 15,000 years when groups crossed the Bering Land Bridge from present-day Russia. Archaeological evidence at Monte Verde II in Chile suggests settlement around 14,500 years ago. By 6,000 years ago, maize cultivation had spread to northern regions, enabling permanent settlements to emerge. Caral-Supe developed along the central Peruvian coast around 3500 BC, establishing one of the earliest cities in human history alongside ancient Egypt. This pre-ceramic culture built monumental architecture including pyramids and sunken plazas while developing sophisticated irrigation systems. Chavín civilization flourished from 900 BC to 300 BC near modern-day Peru, creating religious centers like Chavín de Huantar at high elevations. The Moche people thrived along Peru's northern coast from 100 BC to 700 AD, producing intricate ceramic art and maintaining centralized states with professional militias. Tiahuanaco managed a vast commercial network based on religion across the Altiplano region from 100 BC to 1200 AD. The Inca Empire dominated the Andes from 1438 to 1533, connecting nearly 100 linguistic communities through a 25,000-kilometer road system. Their capital city Cusco featured precise stonework constructed over multiple mountain levels, demonstrating unmatched engineering capabilities for the era.
The Treaty of Tordesillas signed in 1494 divided all lands outside Europe between Spain and Portugal under papal authority. An imaginary line drawn 370 leagues west of Cape Verde Islands allocated most South American territory to Spain while granting Brazil to Portugal. Beginning in the 1530s, foreign conquistadors repeatedly exploited indigenous peoples and natural resources across the continent. European infectious diseases including smallpox, influenza, measles, and typhus caused massive depopulation among native populations lacking immune resistance. Systems of forced labor such as haciendas and mining industry mit'a contributed significantly to population decline. Enslaved Africans arrived midway through the 16th century to replace depleted indigenous workforces, with nearly 40% of all African slaves trafficked to the Americas ending up in Brazil. Between 1501 and 1866, an estimated 4.9 million enslaved people came to Brazil alone. The Portuguese Crown abolished enslavement of indigenous peoples in colonial Brazil in 1750, believing they were unfit for labor compared to enslaved Africans. Spanish colonists primarily enslaved indigenous Americans rather than relying on African slave labor during early settlement phases.
Napoleon's invasion of Portugal in 1807 triggered political upheaval that changed the fate of Spanish and Portuguese colonies. King Ferdinand VII of Spain was captured by Napoleon, who appointed his own brother instead, provoking popular resistance throughout the Americas. Juntas formed to rule in the name of the captured monarchs, initiating independence movements across South America. Simón Bolívar from Venezuela led a great uprising in the north before marching his army south toward Lima, capital of the Viceroyalty of Peru. José de San Martín from Argentina crossed the Andes Mountains with Chilean expatriates to liberate Chile. He organized a fleet to reach Peru by sea while seeking military support from various rebels within the Viceroyalty. At the Guayaquil Conference in Ecuador in 1822, these two leaders failed to agree on governance strategies for liberated nations. Two years later, Bolívar's forces defeated the Spanish at the Battle of Ayacucho, securing independence for Peru and the rest of South America. In Brazil, Dom Pedro I proclaimed the independent Kingdom of Brazil in 1822, which later became the Empire of Brazil. Despite Portuguese loyalties among garrisons in Bahia, Cisplatina, and Pará, independence was diplomatically accepted by Portugal in 1825 following high compensation mediated by the United Kingdom.
The newly independent nations began experiencing fragmentation through civil and international wars shortly after achieving sovereignty. The first separatist attempt occurred in 1820 when Argentine province Entre Ríos declared itself under caudillo General Ramírez, though it never truly intended full independence. In 1825, Cisplatine Province declared independence from Brazil, leading to the Cisplatine War between imperial Brazilian forces and Argentine units. Three years later, Britain intervened to create Uruguay as a new independent country from former Cisplatina territory. During 1836, Rio Grande do Sul proclaimed its own independence motivated by tax crises before being reincorporated into Brazil in 1845. The War of the Confederation broke out between 1836 and 1839 involving the short-lived Peru-Bolivian Confederation against Chile with Argentine support. Paraguay suffered near-total destruction during the Paraguayan War fought from 1864 to 1870 by Argentina, Brazil, and Uruguay. This conflict represented the longest and bloodiest inter-state war in Latin American history, resulting in 40% territorial loss for Paraguay and 60% population reduction including 90% of adult males. The dictator Francisco Solano López ordered invasions of Brazilian provinces Mato Grosso and Rio Grande do Sul without Argentinian approval, triggering broader regional involvement.
The continent became a Cold War battlefield during the late 20th century when military dictatorships overthrew democratically elected governments across multiple nations. Argentina, Brazil, Chile, Uruguay, and Paraguay experienced regime changes throughout the 1960s and 1970s that detained tens of thousands of political prisoners. Many detainees faced torture or death through interstate collaboration among these authoritarian regimes. These governments placed their actions within US Cold War doctrine emphasizing national security against internal subversion. Economically, they transitioned toward neoliberal policies while suppressing opposition through force. Throughout the 1980s and 1990s, Peru endured an internal conflict involving guerrilla movements and state forces. In 1982, Argentina invaded the Falkland Islands, a British dependent territory, leading to a 74-day war ending with Argentine surrender. Colombia maintained ongoing though diminished internal conflict starting in 1964 with creation of Marxist guerrillas known as FARC-EP. Revolutionary movements and right-wing military dictatorships became common after World War II before democratization waves passed through most countries since the 1980s. International indebtedness emerged as significant problem in late 1980s, forcing some democracies to adopt unorthodox economic policies without developing adequate institutions.
South America possesses major mineral resources including gold, silver, copper, iron ore, tin, and petroleum that generate substantial income for producing nations. Brazil stands out as world's largest producer of sugarcane, soy, coffee, orange, guaraná, açaí, and Brazil nut while ranking among top five producers of maize, papaya, tobacco, pineapple, banana, cotton, beans, coconut, watermelon, lemon, and yerba mate. Chile contributes about one-third of global copper production alongside being largest producer of iodine and rhenium in 2019. Peru ranked second globally for copper and silver output while Bolivia produced eighth-largest amounts of silver and fourth-largest quantities of boron. Argentina ranks fourth worldwide in lithium production and seventh in boron extraction. Colombia leads emerald production globally while extracting record amounts of gold between 2006 and 2017. Manufacturing sectors developed significantly from 1930s onward when Great Depression boosted industrial production across the continent. Brazil holds thirteenth most valuable industry globally worth US$174 billion according to 2019 World Bank rankings. The region partially moved away from agriculture achieving high economic growth rates until early 1990s when political instabilities slowed progress. Since end of economic crisis between 1998 and 2002, industrial and service sectors recovered showing good signs of stability with controlled inflation and continuous growth.
