The Shang dynasty (Chinese: 商朝; pinyin: Shāng cháo) or Yin dynasty (Chinese: 殷代; pinyin: Yīn dài), according to traditional historiography, ruled in the Yellow River valley in the second millennium BC, succeeding the Xia dynasty and followed by the Zhou dynasty. The classic account of the Shang comes from texts such as the Book of Documents, Bamboo Annals and Records of the Grand Historian. According to the traditional chronology based upon calculations made approximately 2,000 years ago by Liu Xin, the Shang ruled from 1766 to 1122 BC, but according to the chronology based upon the "current text" of Bamboo Annals, they ruled from 1558 to 1046 BC. The Xia–Shang–Zhou Chronology Project dated them from c. 1600 to 1046 BC.

Archaeological work at the Ruins of Yin (near modern-day Anyang), which has been identified as the last Shang capital, uncovered eleven major Yin royal tombs and the foundations of palaces and ritual sites, containing weapons of war and remains from both animal and human sacrifices. Tens of thousands of bronze, jade, stone, bone, and ceramic artifacts have been obtained.
