Nazca Culture Transition

Timeline

1. 501–550Nazca River basin · PeruIncreasing aridity and frequent El Niño events silted up irrigation systems and salinized farmland. Falling agricultural output eroded the economic base of Nazca chiefdoms, populations concentrated in river valleys that still had water, and some peripheral settlements were abandoned.
2. 520–580Nazca Lines area · Ica RegionTraditional deity images in large geoglyphs and painted pottery tended toward simplification, and sacrificial activities contracted in scale. Archaeology shows changes in late Nazca burial rituals compared with the early and middle periods, reflecting reorganization of the social elite and adjustments in religious belief.
3. 550–600Southern coast of Peru · PeruThe Nazca cultural political entity gradually disintegrated, with new pottery styles and architectural forms appearing in local settlements. Highland Wari cultural influence began penetrating the coastal zone, laying the groundwork for regional political reorganization and the rise of Ica culture in the 7th–8th centuries.
