added by archaeologs Part of a chronological construction used in Peruvian archaeology. There are two clearly separate Intermediate Periods (see Table 9, page 552). The Early Intermediate Period (200 bc-ad 600) is characterized by the rise of the first great city states, such as Moche and Nasca. The Late Intermediate Period (1000-1476) is characterized by the presence of numerous fractionalized corporate units which arose after the decline of Tiahuanaco and Huari, for instance Chimu on the north coast and Aymara around Lake Titicaca.
