Trade and Social Complexity in Coastal Ecuador from Formative Times to European Contact

The trajectories of social development in southern Manabí, Ecuador are reconstructed from the Formative period to European contact to clarify the role played by trade connections. The results of a systematic full-coverage survey suggest that increased interaction between southern Manabí societies and northern Peruvian states could have been an important factor behind the increase in social complexity in the study region beginning ca. A.D. 750. Unlike many models of social development, the archaeological data indicate that this was not an activity undertaken primarily by elite groups, but rather by the general population, which took advantage of the direct economic benefits of trade, particularly of Spondylus shell items.
