Inca

The Inca civilization flourished in ancient Peru between c. 1400 and 1533 CE, and their empire eventually extended across western South America from Quito in the north to Santiago in the south, making it the largest empire ever seen in the Americas and the largest in the world at that time. Undaunted by the often harsh Andean environment, the Incas conquered people and exploited landscapes in such diverse settings as plains, mountains, deserts, and tropical jungle. Famed for their unique art and architecture, they constructed finely-built and imposing buildings wherever they conquered, and their spectacular adaptation of natural landscapes with terracing, highways, and mountaintop settlements continues to impress modern visitors at such world famous sites as Machu Picchu. https://www.ancient.eu/Inca_Civilization/ ; cited 8/13/2020.
