The Zhou Dynasty (1046–256 BC) (Chinese: 周朝; pinyin: Zhōu Cháo; Wade–Giles: Chou Ch'ao ) was a Chinese dynasty that followed the Shang Dynasty and preceded the Qin Dynasty. Although the Zhou Dynasty lasted longer than any other dynasty in Chinese history, the actual political and military control of China by the Ji (Chinese: 姬) family lasted only until 771 BC, a period known as the Western Zhou.
During the Zhou Dynasty, the use of iron was introduced to China, though this period of Chinese history produced what many consider the zenith of Chinese bronze-ware making. The dynasty also spans the period in which the written script evolved into its modern form with the use of an archaic clerical script that emerged during the late Warring States period.
