The Shang Dynasty (Chinese: 商朝; pinyin: shāng cháo) or Yin Dynasty (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 Classic of History, Bamboo Annals and Records of the Grand Historian. According to the traditional chronology based upon calculations by Liu Xin, the Shang ruled between 1766 BC and 1122 BC, but according to the chronology based upon the Bamboo Annals, they ruled between 1556 BC and 1046 BC. The results of the Xia Shang Zhou Chronology Project place them between 1600 BC and 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. The workmanship on the bronzes attests to a high level of civilization.

Sun Wu (simplified Chinese: 孙武; traditional Chinese: 孫武; pinyin: Sūn Wǔ), style name Changqing (長卿), better known as Sun Tzu or Sunzi (simplified Chinese: 孙子; traditional Chinese: 孫子; pinyin: Sūnzǐ; pronounced [swə́n tsɨ̀]), was an ancient Chinese military general, strategist and philosopher who is traditionally believed to be the author of The Art of War, an influential ancient Chinese book on military strategy. Sun Tzu has had a significant impact on Chinese and Asian history and culture, both as an author of The Art of War and through legend.

Sun Tzu, also known as Sun Tze or Sun Wu in other translations, was a historical figure whose authenticity is questioned by historians. Traditional accounts place him in the Spring and Autumn Period of China (722–481 BC) as a military general serving under King Helü of Wu, who lived c. 544–496 BC. Modern scholars accepting his historicity place the completion of The Art of War in the Warring States Period (476–221 BC), based on the descriptions of warfare in the text, and on the similarity of text's prose to other works completed in the early Warring States period.
