The Formative Period on the south coast of Peru: A critical review

Previous and current fieldwork has generated a significant body of data on the occupation of the south coast of Peru during the Formative Period (ca. 3800-2200 B.P.). These data are placed in a synthetic framework and evaluated and compared to the trajectory of cultural development in the better studied regions of the Central Andes. Critical review of this panorama necessitates consideration of the relative chronological framework and definition of the Formative Period, the parameters and validity of the south coast as a culture area, contacts south coast societies sustained with other Central Andean regions, and the role of monumental architecture in the rise of complex society.
