The short-lived Qin dynasty, started by Qin Shi Huang (247-220 BCE), who reunified the Warring States and was the first Chinese ruler to use the title of "emperor", chose Legalism as the state ideology, banning and persecuting all other schools of thought. Confucianism was harshly suppressed, with the burning of Confucian classics and killing of scholars who espoused the Confucian cause .   State ritual of the Qin was indeed similar to the following Han ritual.  Qin Shi Huang personally held sacrifices to Di at Mount Tai , a site dedicated to the worship of the supreme God since pre-Xia times, and in the suburbs of the capital Xianyang .   The emperors of Qin also concentrated the cults of the five forms of God , previously only held at dislocated places, in unified temple complexes.
