Qin Shi Huang is an outstanding statesman, strategist and reformer in the history of China. He inherited the throne at the age of 13. At the age of 39, he unified China and proclaimed himself the First Emperor, establishing the first united, multi-ethnic and centralized country. After the unification of China, he passed a series of reforms, such as standardizing the units of measurements and the currency and unifying the Chinese script. He also undertook gigantic projects such as the construction of the Great Wall and his tomb in his reign. To strengthen his rule, he outlawed and burned classic books and burried some Confucian scholars alive. Although some of his measures brought people heavy disaster, his achievement is far more than his error.
