Recent archaeological survey and excavation in China have demonstrated that large sites of the late fourth and third millennia BC were situated not on the Central Plains—where the later dynastic centres were located—but along the Yangtze and lower Yellow River Basins. Their decline in the late third and second millennia BC coincided with the growth of sites to the north of the Central Plains. Evidence for settlement size and a new chronology constructed from radiocarbon dates emphasise discontinuities in the geographic distribution of settlements, combined with continuity in cultural practices of ritual feasts and the use of symbolic jades.

Erlitou is one of the most important settlements in early China, a prime site for the investigation of early cities and states. Traditionally, it has been described, dated and explained in terms of dynastic succession – the dynasties of the Xia and the Shang being the ethnically-distinct actors and prime movers that made history here. In a brilliant analysis, the authors decouple the semi-legendary textual histories from the up-to-date archaeological sequence at Erlitou itself. This article strikes a blow for archaeological reasoning that will be felt far beyond the Yellow River.
