A processual study of Inka state formation

Abstract

Traditional interpretations of how the Inka empire developed emphasize the disjunctive transformation of a village-level society through the agency of a single charismatic ruler. New evidence from the Inka heartland indicates that it was in fact the formation of a centralized state in the Cusco Valley of highland Peru that enabled the rapid campaigns of Inka territorial expansion during the 15th and 16th centuries. By using archaeological data and ethnohistoric documents to develop independent lines of evidence, it is possible to describe Inka state formation processes anthropologically. Settlement and excavation data from the Vilcanota Valley provide several indicators of the development of a centralized Inka state during the Killke Period (c. A.D. 1000–1400), while multiple accounts of the Inka past describe the transformation of Inka society over a period of several generations leading up to the first campaigns of imperial conquest. Both lines of evidence are consistent with the kinds of changes described for other known cases of state formation. The formation of the Inka state and its expansion in the Cusco region created conditions in which the agency of Inka rulers could direct the expansion of a mighty empire in only a few generations of conquest.
