Throughout its history, South America has had distinct military features: it has been geographically separated from many major military powers by large oceans; its unique terrain has imposed major logistical challenges, and privileged naval lines of communications.

Over the century leading up to Columbus' arrival in the Caribbean archipelago in 1492, the Caribs are believed to have displaced many of the Arawaks who previously settled the island chains, and making inroads into what would now be modern Guyana. The Caribs were skilled boatbuilders and sailors, and owed their dominance in the Caribbean basin to their military skills.

The territory of current-day Brazil had as many as 2,000 tribes prior to European discovery, mostly semi-nomadic peoples who subsisted on hunting, fishing, gathering, and migrant agriculture. One such tribe were the Tupi, who had expanded to inhabit almost all of Brazil's coast, reaching an estimated population of 1 million people by 1500 AD. The Tupi often fought against the other tribes of the region and among themselves, aiming to capture their enemies to later kill them - as amongst the Caribs, cannibalism was a key part of the Tupi

from 900 BC to 300 BC, has left no archaeological trace of warfare. The Moche, however, formed a complex state along the northern coast of Peru from 100 BC – 700 AD, which included warfare. The mummified remains of a Moche woman found in 2005 were accompanied by various military and ornamental artifacts, including war clubs and spear throwers, hinting at the military technology of the Moche. Towards the end of the Moche, later settlements have fortifications and defensive works, but there is no evidence of a foreign invasion, for example by the Wari empire, as many scholars have suggested in the past. There is however some evidence of social unrest, possibly the result of climatic changes as factions fought for control over scarce resources. As the Moche declined, the Wari civilisation was growing in power, lasting from 600 – 1200 AD. The capital city of Wari was located north-east of the modern city of

European invasion

The European invasions of South America in the 16th and 17th centuries, principally by the Spanish and Portuguese, were to have a dramatic impact. The military conquests destroyed the Inca state; the consequent epidemics and social chaos reduced this and other indigenous societies by up to 93%. Few other military events have had as long lasting consequences for a region.

Other factors in the Spaniard's favor were their steel swords, helmets and armour. The Spanish also had three small

In Brazil, these runaway slave communities, emerging from the 16th century onwards, were termed '' Palmares''. By the 1690s, these communities numbered approximately 11,000, living in fortifications called '' macocos''. Six Portuguese expeditions tried to conquer the Palmares between 1680-6, but failed, only retaking the territories in 1694. Despite the huge losses of the previous centuries, the native peoples of South America were not entirely suppressed.

New Granada, Venezuela, Quito

New Granada responded to the troubles in Spain by establishing a sequence of city juntas in mid-1810, deposing the existing viceroy. The splintering of political authority continued as city juntas turned on one another militarily, marking the start of the period known as the ''Patria Boba'', or the Foolish Fatherland. By contrast, in Venezuela, new juntas that emerged formed a joint Congress. The Congress initially upheld the deposed Spanish king's rights, but a faction proposing complete autonomy rapidly won favour, declaring independence as a republic in 1811. Civil war rapidly broke out between the juntas and the royalists in Venezuela. Blockaded by the Spanish regency and defeated at the battle of San Mateo the first Venezuelan republic collapsed in 1812.

Regional wars and discontent in the 19th century

The remainder of the 19th century was a violent time in South America, seeing numerous wars between the newly independent states. The conflicts were driven by the uncertain frontiers of the colonial period, attempts to achieve regional dominance, and the importance of trade and the consequent involvement of many European nations in the internal affairs of the continent. As the century progressed, the growing wealth of South America allowed the creation of larger and more modern armies than in the revolutionary period, with the death toll of the wars increasing as a result.

then invaded Argentina in order to move forces quickly against Brazil, leading to Argentina joining the war on Brazil's side. The triple alliance - Brazil, Argentina and Uruguay - were outnumbered at the start of the conflict on land, but held a clear advantage at sea, thanks to Brazil's naval Armada. Initially, Paraguayan forces had the advantage and advanced rapidly. The alliance responded at the naval battle of Riachuelo in 1865, where the Brazilian fleet commanded by Francisco Manoel Barroso da Silva won, destroying the Paraguayan navy. The battle decided the outcome of the war in favour of the Triple Alliance, as the limitations on road transport mean that rivers were critical to military maneuver. By the end of 1865, the Triple Alliance was on the offensive on land and were prepared to invade Paraguay. The invasion itself ground on, marked by high rates of disease and attrition.

Peru signed a secret treaty of alliance with Bolivia; arguments between Chile and Bolivia grew, Peruvian mediation failed amidst the Chilean discovery of the secret treaty, and in 1879 violence broke out. The desert terrain meant that control of the coastal seas would be decisive; Bolivia had no navy of its own, and Peru faced fiscal problems that rendered many of its vessels unusable. Although also stretched financially, Chile's navy, upgraded and modernised, was in much better shape. Peru fell back on highly effective raiding activity, requiring three naval battles at Chipana,

In 1860, the French lawyer and adventurer named Orélie-Antoine de Tounens visited the region and established ''Nouvelle France'', also sometimes called the Kingdom of Araucania and Patagonia. This provided the trigger for Chilean action, who invaded and captured Orélie-Antoine, detaining him as a lunatic. Over the next twenty years the Chilean military set about building roads and telegraph systems, pacifying the region and forcibly assimilating the Mapuche into Chilean society. The Mapuche fought back, particularly during the

Before the bulk of the work could be completed, however, was launched in 1906, leading Brazil to alter her order for two, far more expensive vessels of a similar design. ''Minas Geraes'' and ''São Paulo'' instantly changed the balance of naval power in the region, sparking a new arms race; Chile ordered the dreadnoughts ''Almirante Latorre'' and ''Almirante Cochrane'' from Britain, and Argentina commissioned two vessels from the United States— ''Rivadavia'' and ''Moreno''. The cost was colossal—over a quarter of each country's annual national income was being spent on naval procurement during the period. These extraordinary monetary sums, combined with a collapse in Brazil's rubber boom and declining trade revenues during the First World War, eventually brought the naval arms race to a halt.

World War II

Once again, Second World War had less military impact on South America than in many parts of the world, with the exception of Brazil. Because the country had joined the war on the Allies side and had allowed the United States to establish naval and air bases on its territory, it came under strong attack by Germany. The Axis powers were interested in disrupting the essential supply lines for the Allies in North Africa campaign. This supply line started in the Brazilian city of Natal. Therefore, Brazil suffered the only Axis attacks in South America. Over 35 Brazilian ships were sunk by German and Italian warships in the South Atlantic. In response to the attacks, the Brazilian Air Force and the Brazilian Navy sank over nine German submarines or U-boats. The following U-boats were sunk just of the coast of Brazil by Brazilian Armed Forces, U-164, U-128, U-590, U-513, U-662, U-598, U-199, U-591 and U-161. The unexpected success of the Brazilian Armed Forces against its U-boats, combined with a strong American presence in the Brazilian territory, made Germany abandon the South Atlantic after 1943. Brazil was also the only South American country to fight in the European war theater, deploying a 25,000 strong joint force - the

Cold War

The Cold War had its impact on South America, albeit less than in many parts of the world, but by the 1970s the ideological struggle was heavily impacting military affairs. On one hand, an increasing number of civilian governments across the region were being ousted by military dictatorships, usually extreme right-wing in nature and allied to the West; on the other hand, an increasing number of left-wing orientated guerrilla and terrorist organizations were being established. The result was a sequence of harsh, dirty military confrontations. In

Domestic opinion in Colombia responded aggressively and demanded a response. In practice, the region was sufficiently remote that this proved difficult. After some desultory fighting both sides signed the Rio de Janeiro Protocol, reaffirming the previous border agreements. Peru and

Falkland Islands war

The unresolved tensions from the British re-establishment of rule on the Falkland Islands in 1833 gave a context for the 1982 conflict between Argentina and the United Kingdom over the islands. The initial invasion in April 1982 was characterised by Argentina as the re-occupation of its own territory, and by the UK as an invasion of a British overseas territory. Britain launched a naval task force to engage the

The use of Britain's nuclear submarine force led to the sinking of the Argentinian cruiser ARA General Belgrano, the Belgrano and the consequent non-intervention of the Argentine navy.Woodward, pp.206-28. In the air, the use of Exocet missiles showed the vulnerability of the British fleet, but the task force successfully landed on islands. A challenging land campaign, including the battle of Goose Green, resulted in the defeat of the Argentinian land forces. At the end of combat operations on 14 June the islands remained under British control. The political effects of the war were strong in both countries, leading to the downfall of the Argentinian military government and the bolstering of government of Prime Minister of the United Kingdom, Prime Minister Margaret Thatcher in the United Kingdom.
