Shang dynasty and Zhou dynasty

The Shang dynasty (Chinese: 商朝; pinyin: Shāngcháo), also known as the Yin dynasty (殷代; Yīn dài), was a Chinese royal dynasty that ruled in the Yellow River valley during the 2nd millennium BC, traditionally succeeding the Xia dynasty and followed by the Western Zhou dynasty. The classic account of the Shang comes from texts such as the Book of Documents, Bamboo Annals and Shiji. Modern scholarship dates the dynasty between the 16th and 11th centuries BC, with more agreement surrounding the end date than beginning date.

The Zhou dynasty ( JOH; Chinese: 周; pinyin: Zhōu, pronunciation: [ʈʂóʊ]) was a royal dynasty of China that existed for 790 years from c. 1046 BC until 256 BC, the longest span of any dynasty in Chinese history. During the Western Zhou period (c. 1046 – 771 BC), the royal house, surnamed Ji, had military control over territories centered on the Wei River valley and North China Plain. Even as Zhou suzerainty became increasingly ceremonial over the following Eastern Zhou period (771–256 BC), the political system created by the Zhou royal house survived in some form for several additional centuries. A date of 1046 BC for the Zhou's establishment is supported by the Xia–Shang–Zhou Chronology Project and David Pankenier, after David Nivison and Edward L. Shaughnessy had previously dated the establishment to 1045 BC.
