Shi Huangdi was the emperor of the Qin Dynasty, and his name means "first emperor". He was a fierce ruler, and he believed in the principles of legalism, which meant that people were naturally bad and needed to be controlled. Therefore, he ordered book burnings about books that rejected the ideals of legalism, anybody caught hiding books was killed, and he even buried scholars that disagreed with him alive. Shi Huangdi believed in good protection for his empire, and even ordered the construction of the Great Wall Of China to protect his empire from the Huns.
