During China’s Bronze Age (c. 2070 – 771 B.C.), the durable alloy was an indispensable resource, central to the development of early Chinese civilization. Under the Zia, Shang, and Zhou dynasties, China developed advanced metallurgy techniques and, along with them, systems for managing them at scale. The Bronze age in China was thus not only characterized by its bronze tools and weaponry, but by its advanced social and political structures.
As reported in the China Daily, excavations over the last two years at the Shenduntou archeological site near the Yangtze River have unearthed around 1,000 artifacts linked to the bronze industry under the Zhou dynasty. While more modest than the ritual bronze vessels prized by museums, these artifacts—simple knives, arrowheads, and broken clay molds—suggest a major metal-working site.
“The discovery of numerous bronze-casting remains proves this was a high-level workshop,” says Wang Zhigao, an archaeology professor at Nanjing Normal University, who is leading the excavation project.
Perhaps even more interesting to Wang and his team was evidence of a “state controlled” system of smelting and casting. This control was reflected in the layout of the site, in which workshop areas–identified by furnaces and bronze artifacts—were enclosed by earthen walls and moats, suggesting oversight and protection.
“This reflects an ‘official industry’ model, in which the state organized and supported production, says Zhang Min, a researcher with Nanjing Museum. “Artisans and merchants were brought together and sustained by government resources to ensure steady manufacturing and trade.”
At the time, while the Zhou royal house nominally ruled the Central Plains, their vassal states competed with one another for resources. Part of the Wu kingdom, Shenduntou’s bronze industry was likely responsible (along with famed military advisor Sun Tsu) for the Wu rulers’ successful territorial expansions in the 6th century BC.
“In that era, bronze technology represented national strength, and the industry was strictly managed by governments,” Wang explains. “Whoever controlled bronze could produce superior weapons and tools.”
