Warring States period

The cult of Huangdi became very popular during the Warring States period (5th century – 221 BC), a period of intense competition between rival states which ended with the unification of the realm by the state of Qin. In addition to his role as ancestor, he became associated with "centralized statecraft" and emerged as a figure paradigmatic of emperorship.
