Introduction It is the aim of PROYECTO de ARQUEOLOGÍA DOMÉSTICA de PUKARA to use data collected from excavations of elite households to determine how aspiring political actors in the Lake Titicaca Basin gained and maintained power during the Upper Formative Period (500 BC- AD 400). The site of Pucará (200 BC- AD 400), located in the northwestern Basin in Peru, was one of two regional population centers during the Upper Formative and covered an area of at least 1km 2 . 1 Following local convention, the spelling “Pucará” refers to the archaeological site and the modern town and the spelling “Pukara” refers to the prehistoric culture. [note: since the presentation of this poster in 2001, we have shifted to using the spelling “Pukara” to also refer to the archaeological site, following the conventions of the Peruvian National Institute of Culture”]
