Sima Qian was a Chinese historian during the early Han dynasty. He is considered the father of Chinese historiography for his Records of the Grand Historian, a general history of China covering more than two thousand years beginning from the rise of the legendary Yellow Emperor and the formation of the first Chinese polity to the reign of Emperor Wu of Han, during which Sima wrote. As the first universal history of the world as it was known to the ancient Chinese, the Records of the Grand Historian served as a model for official history-writing for subsequent Chinese dynasties and the Sinosphere in general until the 20th century.

The Yellow Emperor, also known as the Yellow Thearch or by his Chinese name Huangdi, is a mythical Chinese sovereign and culture hero included among the legendary Three Sovereigns and Five Emperors, and an individual deity (shen) or part of the Five Regions Highest Deities in Chinese folk religion. Calculated by Jesuit missionaries, who based their work on various Chinese chronicles, and later accepted by the twentieth-century promoters of a universal calendar starting with the Yellow Emperor, Huangdi's traditional reign dates are 2697–2597 or 2698–2598 BC.
