Fall of the Shang Dynasty

The last Shang king was killed c. 1150 BCE. The dynasty that ruled next was the Western zhou dynasty(1027-771 BCE). The Zhou kings had asimilar culture to the Shang kings. Thus, the change in dynasty did not result in the end of Shang Civilisation. Around 771 BCE, a group of people killed the Zhou king and his son had to move his capital eastwards. His dynasty was known as the Eastern Zhou dynasty(771-221 BCE).

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.
