Religion
The Shang worshipped a figure they called "Shang Ti," or "Lord on High." This supreme god ruled over lesser gods of the sun, the moon, the wind, the rain, and other natural forces and places. Shang-Ti also regulated human affairs as well as ruling over the material universe. This dual function would, in the Chou dynasty, be attributed to a more abstract figure, "t'ien," or "Heaven." The Shang also believed that their ancestors dwelled in heaven after their death and continued to show an interest in their family and descendants. The obligations within the family included, therefore, the ancestors. Failing in one's duties to the ancestors could bring all sorts of disaster on a family. All of these divine and semi-divine figures, from Shang-Ti to a family's ancestors, were sacrificed to. However, we know little of the nature or the frequency of these sacrifices. We do know, however, that in the Chou dynasty only the king could sacrifice to Shang-Ti; it is highly likely that Shang-Ti was the "local god" of the Shang kings who was subsequently elevated in order to elevate the Shang themselves. The one disturbing fact of Shang sacrifice is that it certainly involved humans; slaves and prisoners of war were often sacrificed by the hundreds when a king died. Lesser numbers were sacrificed at the founding of a palace or temple.
What happened in c.1150BCE?
Shang Zhou, the last Shang king, committed suicide after his army was defeated by the Zhou people. Legends say that his army betrayed him by joining the Zhou rebels in a decisive battle that took place.After Yin's collapse, the surviving Yin ruling family collectively changed their surname from their royal Zi (子) (pinyin: zi; Wade-Giles: tzu) to the name of their fallen dynasty, Yin (殷). The family remained aristocratic and often provided needed administrative services to the succeeding Zhou Dynasty. The King Cheng of Zhou, through the Regent, his uncle the Duke Dan of Zhou, enfeoffed the former Shang King Zhou's brother Ziqi (子啟) as the ruler of Wei (微), in the former Shang capital at Shang (商), with the territory becoming the state of Song later in history. The State of Song and the royal Shang descendants maintained rites to the dead Shang kings which lasted until 286 BC. (Source: Records of the Grand Historian.)
