Chiribaya
Chiribaya was a network of locally led communities along the coast of southern Peru and nearby valleys. Its classic phase lasted from about 1000 to 1360: coastal fishers exchanged their catch with inland farmers who grew maize and chillies.
The lower Osmore valley later came under highland powers, including the Inca Empire. Chiribaya communities remained near the future port of Ilo until the Spanish arrived in the sixteenth century, bringing olive cultivation to the area.
