According to this belief, heaven (天, Tian)--which embodies the natural order and will of the universe--bestows the mandate on a just ruler of the Chinese country, the "Heavenly Son" of the "Celestial Empire". If a ruler was overthrown, this was interpreted as an indication that the ruler was unworthy, and had lost the mandate . It was also a common belief that natural disasters such as famine and flood were signs of heaven's displeasure with the ruler, so there would often be revolts following major disasters as citizens saw these as signs that the Mandate of Heaven had been withdrawn . </P> <P> The Mandate of Heaven does not require a legitimate ruler to be of noble birth, and dynasties such as the Han and Ming dynasties were founded by men of common origins . The Mandate of Heaven had no time limitations, depending instead on the just and able performance of the rulers and their heirs . The concept is in some ways similar to the European concept of the divine right of kings; however, unlike the European concept, it does not confer an unconditional right to rule . Intrinsic to the concept of the Mandate of Heaven was the right of rebellion against an unjust ruler . Chinese historians interpreted a successful revolt as evidence that Heaven had withdrawn its mandate from the ruler . Throughout Chinese history, times of poverty and natural disasters were often taken as signs that heaven considered the incumbent ruler unjust and thus in need of replacement . The Mandate of Heaven was often invoked by philosophers and scholars in China as a way to curtail the abuse of power by the ruler . </P>
