Concept
The Andean civilizations were South American complex societies of many indigenous people. They stretched down the spine of the Andes for 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 civilization is one of the six "pristine" civilizations of the world, created independently and without influence by 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. Less than a century prior to the arrival of the Spanish conquerors, the Incas, from their homeland centered on the city of Cusco, united most Andean cultures into one single empire that encompassed nearly all of what is usually called Andean civilization. The Timoto Cuica of Venezuela remained outside the Inca orbit. The Inca Empire was a patchwork of languages, cultures and peoples. Spanish rule ended or transformed many elements of the Andean civilizations, notably influencing religion and architecture. History of Andean South America After the first humans — who were then arranged into hunter-gatherer tribal groups — arrived in South America via the Isthmus of Panama, they spread out across the continent, with the earliest evidence for settlement in the Andean region dating to circa 15,000 BCE, in what archaeologists call the Lithic Period. In the ensuing Andean preceramic period, plants began to be widely cultivated, and first complex society, Caral-Supe civilization, emerged at 3500 BCE, and lasted until 1800 BCE.
