Shi Huangdi was a ruler in Ancient China. He believed in Legalism. He stopped fighting with other warring states and then kicked out nomadic bands. He also killed critics and people from Confucianism. Legalism was what he used, not Confucianism. Also, he burned the books that he didn't appreciate. Some achievements that Shi Huangdi included the Great Wall of China and Terra Cotta. For the Great Wall, it was from, but bricks and stone. It was a very big wall that was used to prevent nomadic invaders from coming. Criminals and peasants built the Great Wall under Shi Huangdi's command. The Terra Cotta was baked clay in which Shi Huangdi used to make tombs for his army. He ruled the city of Qin.
