The legendary Five Emperors were traditionally regarded as the founders of the Chinese state.
[1] Other sources name Yu the Great, the founder of the Xia dynasty, as the last of the Five.
This is a family tree for the Xia dynasty which ruled circa 2000–1750 BC.
The historicity of the dynasty has sometimes been questioned, but circumstantial archaeological evidence supports its existence.
Ruling from 1046 BC to 256 BC, it is notable as the longest dynasty in Chinese history, although the actual political and military control of China by the dynasty only lasted during the Western Zhou.
