Primary and secondary chiefdom emergence: a comparative view from the Titicaca Basin

Author(s): Alejandra Sejas Portillo

Year: 2015


The main hypothesis that explain the collapse of the Tiwanaku state, which flourished between A.D. 400 and 1250 in the Titicaca Basin, refer to the internal factional competition that destabilized it governance over the years, summed to agricultural production decline caused by draught episodes in the region. It is of great interest to compare the processes of political reconfiguration and the emergence of the post-Tiwanaku Pacajes chiefly polities with the formation of "primary" chiefdoms in this part of the Titicaca Basin. The aim of this poster is to asses this comparison through the study of the supra-local community scale, the supra-local community centralization, demographic density, public works investment, and conflict, observing the trajectory of the polities from the Formative Period (1500 B.C.-A.D. 800), to the Late intermediate Period (A.D. 1150 -1470).
