Qín Shǐ Huáng (Wade-Giles: Chin Shih Huang; Chinese: 秦始皇; 259 BC – 210 BC; personal name: Zhào Zhèng (Wade-Giles: Chao Cheng; Chinese: 趙政); name in classical Chinese: (趙正) was the king of the Chinese State of Qin from 246 BC to 221 BC, during the Warring States Period. He became the first emperor of a unified China in 221 BC. He ruled until his death in 210 BC at the age of 49.

Calling himself the First Emperor (Chinese: 始皇帝, Shǐ Huángdì) after China's unification, Qín Shǐ Huáng is a pivotal figure in Chinese history, ushering nearly two millennia of imperial rule. After unifying China, he and his chief advisor Li Si passed a series of major economic and political reforms. He undertook gigantic projects, including building and unifying various sections of the Great Wall of China, the now famous city-sized mausoleum guarded by the life-sized Terracotta Army, and a massive national road system, all at the expense of numerous lives. To ensure stability, Qin Shi Huang outlawed and burned many books and buried some scholars alive.

Name of Shi Huangdi

Title meaningFrom the beginning of the Zhou dynasty in 1045 BC to the time of the First Emperor, rulers of the Chinese states were titled Wang (Chinese: 王), a term that originally meant "big man" but later came to mean "chief" or "king."

Following his defeat of the last of the Warring States in 221 BC, King Zheng of Qin became de facto ruler of all China. To celebrate this achievement and consolidate his power base, King Zheng created a new title calling himself the First Sovereign Emperor of Qin (Chinese: 秦始皇帝; pinyin: Qín Shǐ Huángdì; Wade–Giles: Ch'in Shih Huang-ti), often shortened to Qin Shi Huang (Chinese: 秦始皇; pinyin: Qín Shǐ Huáng; Wade–Giles: Ch'in Shih-Huang).
