The '''Zhou Dynasty''' (also known as the Chou Dynasty) replaced the [[Shang Dynasty]] in 1027 B.C. It was the longest ruling dynasty in Chinese history.  The Zhou Dynasty continued until 221 B.C.  The early period of the Zhou Dynasty (1027 to 771 B.C.) was remembered in Chinese tradition as a time of peace and prosperity.  In the later period (771 to 221 B.C.) centralized control broke down and warfare among small states became frequent.<ref>The Earth and Its Peoples A Global History, Bulliet et al, 2005</ref>
