South America is a continent located primarily in the Western Hemisphere and mostly in the Southern Hemisphere. It is bounded by the Pacific Ocean to the west, the Atlantic Ocean to the east and the Caribbean Sea to the north. It is connected to North America through the Isthmus of Panama and is commonly considered a distinct continent under the seven continent model.
South America contains twelve sovereign states, Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, Guyana, Paraguay, Peru, Suriname, Uruguay and Venezuela, along with French Guiana, an overseas department and region of France. The continent includes enormous physical and cultural diversity, ranging from the Amazon rainforest and Andes Mountains to the Atacama Desert, Pampas grasslands and Patagonia.
The Andes are South Americas dominant mountain system and extend along much of the western edge of the continent. The range contains numerous high peaks, volcanic systems, plateaus and valleys and strongly influences climate, agriculture, settlement and transportation. The Amazon Basin occupies a vast area of northern South America and contains the Amazon River system and the worlds largest tropical rainforest. Other major physical features include the Brazilian Highlands, Guiana Highlands, Pampas, Gran Chaco, Atacama Desert and Patagonia. The Amazon River has the greatest discharge of any river in the world, while Lake Titicaca is one of the worlds highest navigable lakes. The continents geography creates major contrasts in climate and human settlement.
South America contains tropical, temperate, arid, alpine and subpolar environments. Equatorial conditions dominate much of the Amazon Basin, while deserts occur along the Pacific coast and especially in northern Chile. Temperate grasslands dominate parts of Argentina and Uruguay, while Patagonia contains cool dry landscapes extending toward the southern tip. The Andes create strong variations in temperature and rainfall over short distances because elevation changes rapidly. Ocean currents also influence climate, particularly the cold Humboldt Current along the western coast. The continents biodiversity is exceptionally high, with major ecosystems in the Amazon, Andes, Atlantic Forest, Cerrado, Pantanal and other regions. Environmental change, deforestation, mining, agriculture and climate change have therefore become important regional concerns.
South America has deep Indigenous histories predating European arrival by thousands of years. The Inca Empire became the largest pre Columbian political state in the Americas and controlled extensive territories along the Andes. Numerous other Indigenous societies developed distinct languages, agricultural systems, trading networks and political structures throughout the continent. European conquest began in the sixteenth century, primarily through Spain and Portugal, although Britain, France and the Netherlands also established territories. Portuguese Brazil became the largest European colony in South America, while Spain controlled most of the remaining continental territories. The colonial period introduced European languages, Christianity, new political systems, crops and livestock and resulted in extensive forced labour and the enslavement of Africans.
Most South American countries gained independence during the nineteenth century through movements associated with figures and political groups such as Simon Bolivar, Jose de San Martin and others. Independence did not immediately create political stability, and many countries experienced civil conflicts, military rule, territorial disputes and changing constitutional systems. Borders often developed from colonial administrative divisions and subsequent wars or diplomatic agreements.
The continent includes diverse political systems and national identities, and its history cannot be reduced to a single pattern. Brazil followed a different path from many Spanish American countries because it became an independent empire before becoming a republic, while countries such as Argentina, Chile, Peru and Colombia experienced different sequences of political transformation.
South American economies are diverse and strongly connected to natural resources, agriculture, manufacturing and services. Brazil has the continents largest economy and population and is a major producer of soybeans, coffee, iron ore, aircraft and numerous manufactured and service products. Argentina is important for agriculture, food production and energy, Chile for copper and other minerals, Peru for mining and agriculture, and Colombia for energy, agriculture and services. Venezuela possesses very large petroleum resources. Lithium resources in the Andes region of Argentina, Bolivia and Chile have become increasingly important to global battery supply chains. Hydroelectric power is significant in several countries, and the region has major potential for solar, wind and other renewable energy.
South America is culturally and linguistically diverse. Spanish and Portuguese are the dominant colonial languages, while Dutch is official in Suriname, English in Guyana and French in French Guiana. Hundreds of Indigenous languages remain in use, including Quechua, Aymara, Guarani and many languages belonging to smaller communities. Christianity is historically dominant, particularly Roman Catholicism, while Protestant denominations and other religious communities are also present. Indigenous and African traditions have influenced music, religion, food and cultural practices, particularly in countries such as Brazil, Colombia and parts of the Caribbean coast. Major cities including Sao Paulo, Buenos Aires, Rio de Janeiro, Lima, Bogota and Santiago are important economic and cultural centres.
South America is therefore a continent defined by exceptional physical diversity, long Indigenous histories, European colonial legacies, African and Asian migration, modern nation states and extensive economic interdependence. The Andes and Amazon are globally significant geographic systems, while the continents agricultural, mineral and energy resources have major international importance. Urbanisation has transformed settlement patterns, with large populations concentrated in metropolitan areas despite extensive rural and wilderness regions. Major contemporary issues include deforestation, biodiversity conservation, climate change, inequality, infrastructure development, resource management and Indigenous rights. Understanding South America requires attention to the distinctive histories and environments of its individual countries as well as the continental systems that connect them.
