Qin Shi Huang (, 26010 September 210 BC), born Ying Zheng (嬴政) and also known as King Zheng of Qin (秦王政), was the king of the state of Qin (r. 246–221 BC) who conquered all other Warring States and eventually unified China in 221 BC. Rather than maintain the title of "king" borne by the previous Shang and Zhou rulers, he ruled as the First Emperor (始皇帝) of the Qin dynasty from 220 to 210 BC. His self-invented title "emperor" (, ) would continue to be borne by Chinese rulers for the next two millennia.
