Archaeological investigations at Ñawinpukyo: Change and continuity in an Early Intermediate Period and Middle Horizon community in Ayacucho, Peru : BAR Publishing : 9781407305257 : 1407305255 : 09 Sep 2009 : This work presents a study of the pre-Hispanic occupation at the site of Nawinpukyo (Ayacucho, Peru) during the Early Intermediate Period (EIP) (ca. 200 BC AD 600) and the Middle Horizon (MH) (ca. AD 600-1000). A local and diachronic perspective is adopted to examine the developmental trajectory of this community, in the context of the broader regional processes that took place in the valley during those periods. These processes brought about, especially during the MH, significant cultural changes not only in the Ayacucho Valley but in the whole central Andean area, with the rise of the powerful Wari society and culture.
