Two sets Shang dynasty

Archaeological findings providing evidence for the existence of the Shang dynasty, c. 1600–1046 BC, are divided into two sets. The first set, from the earlier Shang period, comes from sources at Erligang, Zhengzhou, and Shangcheng. The second set, from the later Shang or Yin (殷) period, is at Anyang, in modern-day Henan, which has been confirmed as the last of the Shang's nine capitals (c. 1300–1046 BC).
