Social complexity in north China during the early Bronze Age: a comparative study of the Erlitou and Lower Xiajiadian cultures

The archaeological record of two areas is examined: the Yuxi region of the Zhongyuan, where the Erlitou culture is centered; and the Chifeng-Aohan region of Inner Mongolia, where lower Xiajiadian Culture sites are found. This comparison suggests that these two areas were not fundamentally different. The chronology of these cultures as well as evidence for interaction between societies of the Zhongyuan and the Chifeng-Aohan area are used to challenge the traditional Chinese model that describes the emergence of social complexity as the result of political and cultural expansion from the Zhongyun. Based on these data, several models are presented that emphasize the way these influences were played out at the local level as well as other local processes. -from Author
