Chinese sovereign is the ruler of a particular period in ancient China. Several titles and naming schemes have been used throughout history.
The characters Huang (皇 huáng "god-king") and Di (帝 dì "sage king") had been used separately and never consecutively (see Three August Ones and Five Emperors). The character was reserved for mythological rulers until the first emperor of Qin (Qin Shi Huang), who created a new title Huangdi (皇帝 in pinyin: huáng dì) for himself in 221 BCE, which is commonly translated as Emperor in English. This title continued in use until the fall of the Qing dynasty in 1911.
From the Han Dynasty, the title Huangdi could also be abbreviated to huang or di. The former nobility titles Qing (卿), Daifu (大夫) and Shi (仕) became synonyms for court officials.
The power of the emperor varied between emperors and dynasties, with some emperors being absolute rulers and others being figureheads with actual power lying in the hands of court factions, eunuchs, the bureaucracy or noble families. In principle, the title of emperor was transmitted from father to son via primogeniture, as endorsed by Confucianism. However, there are many exceptions to this rule. For example, because the Emperor usually had many concubines, the first born of the queen (i.e. the wife) is usually the heir apparent. However, Emperors could elevate another more favoured child or the child of a favourite concubine to the status of Crown Prince. Disputes over succession occurred regularly and have led to a number of civil wars. In the Qing dynasty, primogeniture was abandoned altogether, with the designated heir kept secret until after the Emperor's death.
The list of rulers of China includes rulers of China with various titles. From the Zhou dynasty to the Qin dynasty, rulers usually held the title "king" (Chinese: 王; pinyin: wáng). With the separation of China into different Warring States, this title had become so common that the unifier of China, the first Qin Emperor Qin Shihuang created a new title for himself, that of "emperor" (pinyin: huángdì). The title of emperor of China continued to be used for the remainder of China's imperial history, right down to the fall of the Qing dynasty in 1912. While many other monarchs existed in and around China throughout its history, this list covers only those with a quasi-legitimate claim to the majority of China, or those who have traditionally been named in king-lists. The following list of Chinese monarchs is in no way comprehensive. Chinese sovereigns were known by many different names, and how they should be identified is often confusing. Sometimes the same emperor is commonly known by two or three separate names, or the same name is used by emperors of different dynasties. The tables below do not necessarily include all of an emperor's names – for example, posthumous names could run to more than twenty characters and were rarely used in historical writing – but, where possible, the most commonly used name or naming convention has been indicated.
