Qin Shi Huang, Chinese emperor (d. 210 BC)
Qin Shi Huang (Chinese: 秦始皇; lit. 'First Emperor of Qin', pronunciation ; 259–210 BCE), or Shihuangdi, was the founder of the Qin dynasty, and first emperor of a unified China. Rather than maintain the title of "king" (王 wáng) borne by the previous Shang and Zhou rulers, he ruled as the First Emperor (始皇帝) of the Qin dynasty from 221 to 210 BCE. His self-invented title "emperor" (皇帝 huángdì) would continue to be borne by Chinese rulers for the next two millennia. Historically, he was often portrayed as a tyrannical ruler and strict Legalist, in part from the Han dynasty's scathing assessments of him. Since the mid 20th-century, scholars have begun to question this evaluation, inciting considerable discussion on the actual nature of his policies and reforms. Regardless, according to sinologist Michael Loewe "few would contest the view that the achievements of his reign have exercised a paramount influence on the whole of China's subsequent history, marking the start of an epoch that closed in 1911".Born in the Zhao state capital Handan, as Ying Zheng (嬴政) or Zhao Zheng (趙政), his parents were King Zhuangxiang of Qin and Lady Zhao. The wealthy merchant Lü Buwei assisted him in succeeding his father as the ruler of Qin, after which he became King Zheng of Qin (秦王政). When he was 38, the Qin had conquered all of the other Warring States and unified all of China in 221 BCE, resulting in his ascension as China's first emperor. During his reign, his generals greatly expanded the size of the Chinese state: campaigns south of Chu permanently added the Yue lands of Hunan and Guangdong to the Chinese cultural orbit; campaigns in Central Asia conquered the Ordos Loop from the nomad Xiongnu, although eventually it would also lead to their confederation under Modu Chanyu.

Qin Shi Huang also worked with his minister Li Si to enact major economic and political reforms aimed at the standardization of the diverse practices of the earlier Chinese states. He is traditionally said to have banned and burned many books and executed scholars. His public works projects included the unification of diverse state walls into a single Great Wall of China and a massive new national road system, as well as the city-sized mausoleum guarded by the life-sized Terracotta Army. He ruled until his death in 210 BCE during his fourth tour of Eastern China.
