胡亥
The Qin dynasty (秦朝) was established in 221 BCE after Qin Shi Huang, King of Qin, conquered his final independent neighbour, the state of Qi. It is now recognised as the first Chinese imperial dynasty in the modern sense of the term; in recognition of this, its rulers were for the first time titled "Emperor" (皇帝), a title of which the components are drawn from legend, higher than the previous title "King" (王). The ancestral name of the family was Ying (嬴), although it is anachronistic to regard this as a family name in the modern sense: it would not have been used together with a given name. The titles of the Qin emperors were literally regnal numbers: "Qin Shi Huang" (秦始皇), in full "Qin Shi Huangdi" (秦始皇帝) means literally "the first Emperor of Qin", "Qin Er Shi" (秦二世), in full "Qin Er Shi Huangdi" (秦二世皇帝) means "the second Emperor of Qin", and so forth.
