What marks the end of prehistory times?
A legend has it that the Emperor Yellow (Huang Di), lived about 4,000 years ago was the head of the tribal confederation along the Yellow River watershed. He led his people against a clan headed by Emperor Yan (Yan Di), and then they formed an alliance that became the origin of the Chinese people.After Emperor Yellow, Yao and Shun were successively elected as the leaders of the Yellow River watershed. Later, Yu was made as the leader because he made great contributions in controlling the floods. However, Qi, the son of Yu, abolished the Abdication System and replaced it with a Hereditary System, made himself king, and established Xia Dynasty, the first dynasty in Chinese history. The introduction of the Hereditary System is a clear indicator that the Prehistoric Times of China had ended and China had entered into her Ancient Civilization era.
