1370-1470 CE
From 1370 to 1470 CE, the Chimor stretched their desert empire along a thousand miles of Peruvian coast — Chan Chan's adobe walls enclosing the largest city in pre-Columbian South America, its rulers commanding irrigation networks that made the desert bloom. Their goldsmiths created treasures that Inca emperors would covet; their conquest by Tupac Inca Yupanqui delivered both craftsmen and techniques to Cusco, enriching the empire that had devoured them.
