Nazca culture
Summary
The Nazca culture (also Nasca) was the archaeological culture that flourished from 100 BC to 800 AD beside the arid, southern coast of Peru in the river valleys of the Rio Grande de Nazca drainage and the Ica Valley. Strongly influenced by the preceding Paracas culture, which was known for extremely complex textiles, the Nazca produced an array of crafts and technologies such as ceramics, textiles, and geoglyphs.
They are known for two extensive construction projects that would have required the coordination of large groups of laborers: the Nazca Lines, immense designs in the desert whose purpose is unknown, and puquios, underground aqueducts for providing water for irrigation and domestic purposes in the arid environment. Several dozen still function today. The Nazca Province in the Ica Region was named for this people.
Nazca society developed during the Early Intermediate Period and is generally divided into the Proto Nazca (phase 1, 100 BC – 1 AD), the Early Nazca (phases 2–4, 1–450 AD), Middle Nazca (phase 5, 450–550 AD) and Late Nazca (phases 6–7, 550–750 AD) cultures.
From 500 AD, the civilization started to decline and by 750 AD the civilization had fallen completely. This is thought to have occurred when an El Niño triggered widespread and destructive flooding. Evidence also suggests that the Nazca people may have exacerbated the effects of these floods by gradually cutting down Prosopis pallida trees to make room for maize and cotton agriculture. These trees play an extremely important role as the ecological keystone of this landscape: in particular preventing river and wind erosion. Gradual removal of trees would have exposed the landscape to the effects of climate perturbations such as El Niño, leading to erosion and leaving irrigation systems high and dry.
Early Nazca society was made up of local chiefdoms and regional centers of power that developed around Cahuachi, a non-urban ceremonial site of earthwork mounds and plazas. Scholars have developed theories resulting from various excavations at Cahuachi.
