What ancient civilization lived in Machu Picchu?

Often referred to as the "Lost City of the Incas", Machu Picchu is the most familiar icon of the Inca civilization. The Incas built the estate around 1450 but abandoned it a century later, at the time of the Spanish conquest. According to the new AMS radiocarbon dating, it was occupied from c. 1420–1532. Historical research published in 2022 claims that the site was probably called Huayna Picchu by the Inca, as it exists on the smaller peak of the same name.
