Dapeng or Great Peng, also known simply as Peng, was a Chinese Bronze Age state that was centered at Xuzhou and Qiuwan in northern Jiangsu. First mentioned on oracle bones dating to the early 11th century BC, Dapeng was a contemporary of the late Shang dynasty, with whom it shared an ambiguous relationship. At times, the two polities were allies and trading partners, but at least on two occasions war broke out among them, eventually leading to Dapeng's destruction by King Di Xin of Shang around 1060 BC.
History
According to the Spring and Autumn period's Guoyu , the Han dynasty's Shiben , and the Tang dynasty's Kuodi Zhi , Dapeng was founded by Peng Zu, who was made marquis by the kings of the Shang dynasty. After his death, the state declined under his descendants. Due to the lack of contemporary written sources, it remains impossible to verify this information. Archaeological excavations at Qiuwan, likely the kingdom's capital, have shown that the state was under strong Shang influence since the early Yinxu period. According to the Warring States period's Yu Gong, the whole Xuzhou area, including Dapeng, regularly sent tribute to the Shang centres in the Central Plain. Major tributary goods included pearls, shells, and rare woods. Archaeological findings seem to corroborate these records, as large quantities of shells have been uncovered from Qiuwan, and the Xuzhou area appears to have served as major trading hub since the 3rd millennium BC. Under the rule of King Wu Ding, hostilities broke out, and the Shang dynasty possibly invaded Dapeng. According to Sima Qian, Dapeng and its ruling dynasty were eventually destroyed by the Shang royal army in the 11th century BC due to the "unjust behaviour" of Peng Zu's successors. Modern historians such as Chen Mengjia, Li Xueqin, and Shima Kunio believed that this campaign against Dapeng is likely related to King Di Xin's military expedition into the Huai River valley that was recorded on oracle bones. A few decades after the destruction of Dapeng and the abandonment of Qiuwan, the state of Xu emerged in its direct vicinity. It remains unknown if there was any relation between these two polities.
Religion
The people of Dapeng, influenced by both Shang as well as local traditions, probably practised human sacrifice. At Qiuwan a sacrificial altar was found, consisting of a one meter high natural stone, surrounded by three large, erected stones. Around these stones, 22 human and 10 dog skeletons were found; most humans were executed by blows to the head. Twenty were then buried in a crouched position, the head to the ground with their arms tied behind their backs. The other two were only represented by their skulls. The remains dated from 1400–1000 BC, indicating that the site was used for a long time. The excavators interpreted the findings as sacrifices to the Sheji, God of Earth, who was symbolized by standing rocks, prayed to for a good harvest, and whose cult was prevalent among the eastern tribes as well as the Shang people.
