Indigenous peoples of South America in the context of "Zambos"

The Andean civilizations were South American complex societies of many indigenous people. They stretched down the spine of the Andes for 4,000 km (2,500 miles) from southern Colombia, to Ecuador and Peru, including the deserts of coastal Peru, to north Chile and northwest Argentina. Archaeologists believe that Andean civilizations first developed on the narrow coastal plain of the Pacific Ocean. The Caral or Norte Chico civilization of coastal Peru is the oldest known civilization in the Americas, dating back to 3500 BCE. Andean civilizations are one of at least five civilizations in the world deemed by scholars to be "pristine." The concept of a "pristine" civilization refers to a civilization that has developed independently of external influences and is not a derivative of other civilizations.

Despite the severe environmental challenges of high mountains and hyper-arid desert, the Andean civilizations domesticated a wide variety of crops, some of which, such as potatoes, peppers, peanuts, manioc, chocolate, and coca, became of worldwide importance. The Andean civilizations were noteworthy for monumental architecture, an extensive road system, textile weaving, and many unique characteristics of the societies they created.

The Galápagos Islands (Spanish: Islas Galápagos) are an archipelago of volcanic islands in the Eastern Pacific, located around the equator, 900 km (560 mi) west of the mainland of South America. They form the Galápagos Province of the Republic of Ecuador, with a population of slightly over 33,000 (2020). The province is divided into the cantons of San Cristóbal, Santa Cruz, and Isabela, the three most populated islands in the chain. The Galápagos are famous for their large number of endemic species, which were studied by Charles Darwin in the 1830s and inspired his theory of evolution by means of natural selection. All of these islands are protected as part of Ecuador's Galápagos National Park and Marine Reserve.

There is no firm evidence that Polynesians or the Indigenous peoples of South America reached the islands before their accidental discovery by Bishop Tomás de Berlanga in 1535. If some visitors did arrive, poor access to fresh water on the islands seems to have limited settlement. The Spanish Empire similarly ignored the islands, although during the Golden Age of Piracy various pirates used the Galápagos as a base for raiding Spanish shipping along the Peruvian coast. The goats and black and brown rats introduced during this period greatly damaged the existing ecosystems of several islands. British sailors were chiefly responsible for exploring and mapping the area. Darwin's voyage on HMS Beagle was part of an extensive British survey of the coasts of South America. Ecuador, which won its independence from Spain in 1822 and left Gran Colombia in 1830, formally occupied and claimed the islands on 12 February 1832 while the voyage was ongoing. José de Villamil, the founder of the Ecuadorian Navy, led the push to colonize and settle the islands, gradually supplanting the English names of the major islands with Spanish ones. The United States built the islands' first airport as a base to protect the western approaches of the Panama Canal in the 1930s. After World War II, its facilities were transferred to Ecuador. With the growing importance of ecotourism to the local economy, the airport modernized in the 2010s, using recycled materials for any expansion and shifting entirely to renewable energy sources to handle its roughly 300,000 visitors each year.

The Indigenous peoples in Ecuador or Native Ecuadorians (Spanish: Ecuatorianos Nativos) are the groups of people who were present in what became Ecuador before the Spanish colonization of the Americas. The term also includes their descendants from the time of the Spanish conquest to the present. Their history, which encompasses the last 11,000 years, reaches into the present; 7 percent of Ecuador's population is of Indigenous heritage, while another 70 percent are Mestizos of mixed Indigenous and European heritage. Genetic analysis indicates that Ecuadorian Mestizos are of three-hybrid genetic ancestry.

The Spanish conquest of the Inca Empire, also known as the Conquest of Peru, was one of the most important campaigns in the Spanish colonization of the Americas. After years of preliminary exploration and military skirmishes, 168 Spanish soldiers under conquistador Francisco Pizarro, along with his brothers in arms and their indigenous allies, captured the last Sapa Inca, Atahualpa, at the Battle of Cajamarca in 1532. It was the first step in a long campaign that took decades of fighting but ended in Spanish victory in 1572 and colonization of the region as the Viceroyalty of Peru. The conquest of the Inca Empire (called "Tahuantinsuyu" or "Tawantinsuyu" in Quechua, meaning "Realm of the Four Parts"), led to spin-off campaigns into present-day Chile and Colombia, as well as expeditions to the Amazon Basin and surrounding rainforest.

When the Spanish arrived at the borders of the Inca Empire in 1528, it spanned a considerable area and was by far the largest of the four grand pre-Columbian civilizations. Extending southward from the Ancomayo, which is now known as the Patía River, in southern present-day Colombia to the Maule River in what would later be known as Chile, and eastward from the Pacific Ocean to the edge of the Amazonian jungles, it covered some of the most mountainous terrains on Earth. In less than a century, the Inca had expanded their empire from about 400,000 km (150,000 sq mi) in 1448 to 1,800,000 km (690,000 sq mi) in 1528, just before the arrival of the Spanish. This vast area of land varied greatly in culture and climate. Because of the diverse cultures and geography, the Inca allowed many areas of the empire to be governed under the control of local leaders, who were watched and monitored by Inca officials. Under the administrative mechanisms established by the Inca, all parts of the empire answered to, and were ultimately under the direct control of, the Inca Emperor. Scholars estimate that the population of the Inca Empire was between 12 and 16 million.

Spirit possession is an altered state of consciousness and associated behaviors purportedly caused by the control of a human body and its functions by spirits, ghosts, demons, angels, or gods. The concept of spirit possession exists in many cultures and religions, including Buddhism, Christianity, Dominican Vudú, Haitian Vodou, Hinduism, Islam, Judaism, Wicca, and Southeast Asian, African, and Native American traditions. Depending on the cultural context in which it is found, possession may be thought of as voluntary or involuntary and may be considered to have beneficial or detrimental effects on the host. The experience of spirit possession sometimes serves as evidence in support of belief in the existence of spirits, deities or demons. In a 1969 study funded by the National Institute of Mental Health, spirit-possession beliefs were found to exist in 74% of a sample of 488 societies in all parts of the world, with the highest numbers of believing societies in Pacific cultures and the lowest incidence among Native Americans of both North and South America. As Pentecostal and Charismatic Christian churches move into both African and Oceanic areas, a merger of belief can take place, with demons becoming representative of the "old" indigenous religions, which Christian ministers attempt to exorcise.

The Guarani are a group of culturally-related Indigenous peoples of South America. They are distinguished from the related Tupi by their use of the Guarani language. The traditional range of the Guarani people is in what is now Paraguay between the Paraná River and lower Paraguay River, the Misiones Province of Argentina, southern Brazil once as far east as Rio de Janeiro, and parts of Uruguay and Bolivia.

Although their demographic dominance of the region has been reduced by European colonisation and the commensurate rise of mestizos, there are contemporary Guarani populations in Paraguay and parts of Argentina and Bolivia. Most notably, the Guarani language, still widely spoken across traditional Guarani homelands, is one of the two official languages in Paraguay, the other one being Spanish. The Paraguayan population learns Guarani both informally from social interaction and formally in public schools. In modern Spanish, Guaraní also refers to any Paraguayan national in the same way that the French are sometimes called Gauls.

Quechua people (/ˈkɛtʃuə/, US also /ˈkɛtʃwɑː/; Spanish: [ˈketʃwa]) , Quichua people or Kichwa people are Indigenous peoples of South America who speak the Quechua languages, which originated among the Indigenous people of Peru. Although most Quechua speakers are native to Peru, there are some significant populations in Ecuador, Bolivia, Chile, Colombia, and Argentina.

The most common Quechua dialect is Southern Quechua. The Kichwa people of Ecuador speak the Kichwa dialect; in Colombia, the Inga people speak Inga Kichwa.
