Settlement Patterns and Development of Social Complexity in the Yiluo Region, North China

AbstractAbstractThis international, collaborative, and interdisciplinary archaeological program examines changes in settlement patterns from the early Neolithic to the full development of states (ca. 6500–200 B.C.) in the Yiluo region of central north China. Full-coverage regional surveys are integrated with geoarchaeological investigations, ethnobotanical studies, and lithic analyses. The data are used to assess changes in population, environment, land use, agricultural production, and craft production, and to test theoretical propositions regarding the emergence and development of social complexity. Research results suggest a significant sociopolitical transformation taking place in the Yiluo basin during the Erlitou period, including the development of the first four-tiered settlement hierarchy, marked population nucleation, and economic integration between urban center and rural areas. These changes indicate the emergence of the earliest state in China.
