Emperor of China
The emperor of China, or Huángdì (), was the monarch of China during the imperial period of Chinese history. In traditional Chinese political theory, the emperor was considered the Son of Heaven and the autocrat of All under Heaven. Under the Han dynasty, Confucianism replaced Legalism as the official political theory and succession theoretically followed agnatic primogeniture. The succession of emperors in a paternal family line constituted a dynasty. The absolute authority of the emperor came with a variety of governing duties and moral obligations; failure to uphold these was thought to remove the dynasty's Mandate of  Heaven and to justify its overthrow. In practice, emperors sometimes avoided the strict rules of succession and dynasties' ostensible "failures" were detailed in official histories written by their successful replacements. The power of the emperor was also limited by the imperial bureaucracy, which was staffed by scholar-officials and in some dynasties eunuchs. An emperor was also constrained by filial obligations to his ancestors' policies and dynastic traditions, such as those detailed in the Ming dynasty's "Ancestral Instructions". Origin and history. During the Zhou dynasty (c. 1046 BC – 256 BC), Chinese feudal rulers with power over their particular fiefdoms  were called "gong" () but, as the power of the Shang and Zhou kings (,  "wang") waned, the dukes began to usurp that title for themselves. In 221 BCE, after the then-king of Qin completed the conquest of the various kingdoms of the Warring States period, he adopted a new title to reflect his prestige as a ruler greater than the rulers before him. He called himself "Shi Huangdi", the First Emperor. Before this, "Huang" () and "Di" () were the nominal "titles" of eight rulers of Chinese mythology or prehistory: The three "Huang" (, "august, sovereign") were godly rulers credited with feats like  ordering the sky and forming the first humans out of clay; the five "Di" (, , also often translated as "emperor" but also meaning "the God of Heaven") were cultural heroes credited with the invention of agriculture, clothing, astrology, music, etc. In the 3rd century BCE, the two titles had not previously been used together. Because of the god-like powers of the "Huang", the folk worship of the "Di", and the latter's use in the name of the God of Heaven Shangdi, however, the First Emperor's title would have been understood as implying "The August Ancestor", "The Holy Ruler , or The Divine Lord". On that account, some modern scholars translate the title as "thearch". On occasion, the father of the ascended emperor was still alive. Such an emperor was titled the "Taishang Huang" (), the "Grand Imperial Sire". The practice was initiated by the First Emperor, who gave the title as a posthumous name to his own father. Liu Bang, who established the Han dynasty, was the first to become emperor while his father yet lived. It was said he granted the title during his father's life because he would not be bowed to by his own father, a  commoner. Owing to political fragmentation, over the centuries, it has not been uncommon to have numerous claimants to the title of "Emperor of All China". The Chinese political concept of the Mandate of Heaven essentially legitimized those claimants who emerged victorious. The proper list was considered those made by the official dynastic histories; the compilation of a history of the preceding dynasty was considered one of the hallmarks of legitimacy, along with symbols such as the Nine Ding or the Heirloom Seal of the Realm. As with the First Emperor, it was very common also to retroactively grant posthumous titles  to the ancestors of the victors; even in Chinese historiography, however, such grants were not considered to elevate emperors prior to the successful declaration of a new dynasty. The Yuan and Qing dynasties were founded by successful invaders; as part of their rule over China, however, they also went through the rituals of formally declaring a new dynasty and taking on the Chinese title of "Huangdi", in addition to the titles of their respective people. Thus, Kublai Khan was simultaneously khagan of the Mongols and emperor of China. End of the emperors. In 1911, the title of Prime Minister of  the Imperial Cabinet was created to rule alongside the emperor, as part of an attempt to turn China into a constitutional monarchy. The Xuantong Emperor (Puyi) of the Qing dynasty was the de jure last emperor of China, abdicated on 12 February 1912, thus ending the imperial tradition after more than 2,100 years. Yuan Shikai, former President of the Republic of China, attempted to restore a monarchy with himself as the Hongxian Emperor, however his reign as emperor ended on 22 March 1916. Puyi was briefly restored for almost two weeks during a coup in 1917 but was overthrown again  shortly after. He later became the emperor of Manchukuo, a Japanese puppet state, and was captured by the Red Army as a prisoner of war after World War II and held in Chita, Soviet Union. He was returned to China and rehabilitated in Fushun War Criminals Management Centre, and after he was released lived until 1967. Number of emperors. Confucian historiography holds that there can only be one legitimate Son of Heaven at any given time. However, identifying the "legitimate" emperor during times of division is not always uncontroversial, and therefore the exact number of legitimate emperors depends on where  one stands on a number of succession disputes. The two most notable such controversies are whether Wei or Shu was the legitimate dynasty during the Three Kingdoms, and at what point the Song dynasty ceased to be the legitimate dynasty in favor of the Yuan dynasty. The Qing view, reported to Europe by the Jesuits, was that there had been 150 emperors from the First Emperor to the Kangxi Emperor. Adding the eight uncontroversial emperors that followed the Kangxi Emperor would give a grand total of 158 emperors from the First Emperor to Puyi. By one count, from the Qin  dynasty to the Qing dynasty, there were a total 557 individuals who at one point or another claimed the title "emperor", several of them simultaneously. Some, such as Li Zicheng, Huang Chao, and Yuan Shu, declared themselves the emperors, Son of Heaven and founded their own empires as a rival government to challenge the legitimacy of and overthrow the existing emperor. Among the most famous emperors were Qin Shi Huang of the Qin dynasty, the emperors Gaozu and Wu of the Han dynasty, Emperor Taizong of the Tang dynasty, Kublai Khan of the Yuan dynasty, the Hongwu Emperor of the  Ming dynasty, and the Kangxi Emperor of the Qing dynasty. Power. The emperor's words were considered sacred edicts () and his written proclamations "directives from above" (). In theory, the emperor's orders were to be obeyed immediately. He was elevated above all commoners, nobility and members of the Imperial family. Addresses to the emperor were always to be formal and self-deprecatory, even by the closest of family members. In practice, however, the power of the emperor varied between different emperors and different dynasties. Generally, in the Chinese dynastic cycle, emperors founding a dynasty usually consolidated the empire through absolute  rule: examples include Qin Shi Huang of the Qin, Emperor Gaozu of Han, Emperor Guangwu of Han, Emperor Taizong of the Tang, Kublai Khan of the Yuan, and the Kangxi Emperor of the Qing. These emperors ruled as absolute monarchs throughout their reign, maintaining a centralized grip on the country. During the Song dynasty, the emperor's power was significantly overshadowed by the power of the chancellor. The emperor's position, unless deposed in a rebellion, was always hereditary, usually by agnatic primogeniture. As a result, many emperors ascended the throne while still children. During these minorities, the Empress Dowager  (i.e., the emperor's mother) would possess significant power. In fact, the vast majority of female rulers throughout Chinese Imperial history came to power by ruling as regents on behalf of their sons; prominent examples include the Empress Lü of the Han dynasty, as well as Empress Dowager Cixi and Empress Dowager Ci'an of the Qing dynasty, who for a time ruled jointly as co-regents. Where Empresses Dowager were too weak to assume power, court officials often seized control. Court eunuchs had a significant role in the power structure, as emperors often relied on a few of them as  confidants, which gave them access to many court documents. In a few places, eunuchs wielded vast power; one of the most powerful eunuchs in Chinese history was Wei Zhongxian during the Ming dynasty. Occasionally, other nobles seized power as regents. The actual area ruled by the Emperor of China varied from dynasty to dynasty. In some cases, such as during the Southern Song dynasty, political power in East Asia was effectively split among several governments; nonetheless, the political fiction that there was but one ruler was maintained. Heredity and succession. The title of "emperor" was hereditary, traditionally passed on from  father to son in each dynasty. There are also instances where the throne is assumed by a younger brother, should the deceased emperor have no male offspring. By convention in most dynasties, the eldest son born to the Empress () succeeded to the throne. In some cases when the empress did not bear any children, the emperor would have a child with another of his many wives (all children of the emperor were said also to be the children of the empress, regardless of birth mother). In some dynasties the succession of the empress' eldest son was disputed, and because many  emperors had large numbers of progeny, there were wars of succession between rival sons. In an attempt to resolve after-death disputes, the emperor, while still living, often designated a Crown Prince (). Even such a clear designation, however, was often thwarted by jealousy and distrust, whether it was the crown prince plotting against the emperor, or brothers plotting against each other. Some emperors, like the Yongzheng Emperor, after abolishing the position of Crown Prince, placed the succession papers in a sealed box, only to be opened and announced after his death. Unlike, for example, the Japanese monarchy, Chinese political theory  allowed for a change in the ruling house. This was based on the concept of the "Mandate of Heaven". The theory behind this was that the Chinese emperor acted as the "Son of Heaven" and held a mandate to rule over everyone else in the world; but only as long as he served the people well. If the quality of rule became questionable because of repeated natural disasters such as flood or famine, or for other reasons, then rebellion was justified. This important concept legitimized the dynastic cycle or the change of dynasties. This principle made it possible even for  peasants to found new dynasties, as happened with the Han and Ming dynasties, and for the establishment of conquest dynasties such as the Mongol-led Yuan dynasty and Manchu-led Qing dynasty. It was moral integrity and benevolent leadership that determined the holder of the "Mandate of Heaven". There has been only one lawful female reigning emperor in China, Empress Zetian, who briefly replaced the Tang dynasty with her own Zhou dynasty. Many women, however, did become "de facto" leaders, usually as Empress Dowager. Prominent examples include Empress Dowager Lü of the Han dynasty, Empress Dowager Liu of the Sung  dynasty and Empress Dowager Cixi of the Qing dynasty. Styles, names and forms of address. As the emperor had, by law, an absolute position not to be challenged by anyone else, his or her subjects were to show the utmost respect in his or her presence, whether in direct conversation or otherwise. When approaching the Imperial throne, one was expected to kowtow before the emperor. In a conversation with the emperor, it was considered a crime to compare oneself to the emperor in any way. It was taboo to refer to the emperor by his or her given name, even  for the emperor's own mother, who instead was to use "Huángdì" (), or simply "Ér" (, "son", for male emperor). The emperor was never to be addressed as "you". Anyone who spoke to the emperor was to address him or her as "Bìxià" (, the "Bottom of the Steps"), corresponding to "Your Imperial Majesty"; "Huáng Shàng" (, lit. "Radiant Highness"); "Shèng Shàng" (, "Holy Highness"); or "Tiānzǐ" (, "Son of Heaven"). The emperor could also be alluded to indirectly through reference to the imperial dragon symbology. Servants often addressed the emperor as "Wàn Suì Yé" (, lit. "Lord of Ten Thousand Years"). The emperor referred to  himself or herself as "Zhèn" (), the original Chinese first-person singular arrogated by the First Emperor, functioning as an equivalent to the "Royal We", or, self-deprecatingly, "Guǎrén" (, the "Morally-Deficient One") in front of his or her subjects. In contrast to the Western convention of referring to a sovereign using a regnal name (e.g. George V) or by a personal name (e.g. Queen Victoria), a governing emperor was to be referred to simply as "Huángdì Bìxià" (, "Majesty|His/Her Majesty the Emperor") or "Dāngjīn Huángshàng" (, "The Present Emperor Above") when spoken about in the third person. Under the Qing, the  emperor was usually styled "His Imperial Majesty the Emperor of the Great Qing Dynasty, Son of Heaven, Lord of Ten Thousand Years" although this varied considerably. Generally, emperors also ruled with an era name (). Since the adoption of era name by Emperor Wu of Han and up until the Ming dynasty, the sovereign conventionally changed the era name semi-regularly during his or her reign. During the Ming and Qing Dynasties, emperors simply chose one era name for their entire reign, and people often referred to past emperors with that title. In earlier dynasties, the emperors were known with a  temple name () given after their death. Most emperors were also given a posthumous name (, Shìhào), which was sometimes combined with the temple name (e.g. Emperor Shèngzǔrén for the Kangxi Emperor). The passing of an emperor was referred to as "Jiàbēng" (, lit. "collapse of the [imperial] chariot") and an emperor that had just died was referred to as "Dàxíng Huángdì" (), literally "the Emperor of the Great Journey." Wives, concubines, and children. The Imperial family was made up of the emperor and the empress () as the primary consort and Mother of the Nation (). In addition, the emperor would typically have several other  consorts and concubines (), ranked by importance into a harem, in which the Empress was supreme. Every dynasty had its set of rules regarding the numerical composition of the harem. During the Qing dynasty (1644–1911), for example, imperial convention dictated that at any given time there should be one Empress, one "Huang Guifei", two "Guifei", four "fei" and six "pin", plus an unlimited number of other consorts and concubines. Although the emperor had the highest status by law, by tradition and precedent the mother of the emperor, "i.e.", the empress dowager (), usually received the greatest respect in the palace and was  the decision maker in most family affairs. At times, especially when a young emperor was on the throne, she was the "de facto" ruler. The emperor's children, the princes () and princesses (), were often referred to by their order of birth, "e.g.", Eldest Prince, Third Princess, etc. The princes were often given titles of peerage once they reached adulthood. The emperor's brothers and uncles served in court by law, and held equal status with other court officials (). The emperor was always elevated above all others despite any chronological or generational superiority. Ethnicity. Recent scholarship is wary of applying present -day ethnic categories to historical situations. Most Chinese emperors have been considered members of the Han ethnicity, but those in the dynasties following the disintegration of the Han dynasty included non-Han, such as the Yuan dynasty which was ruled by Mongols. Nomads from the Eurasian steppe repeatedly conquered northern China and claimed the title of emperor. The most successful of these were the Khitans (Liao dynasty), Jurchens (Jin dynasty), Mongols (Yuan dynasty), and Manchus (Qing dynasty). The orthodox historical view sees these as dynasties as sinicized polities as they adopted Chinese culture, claimed the Mandate of Heaven, and performed  the traditional imperial obligations such as annual sacrifices to Heaven (as Tian or Shangdi) for rain and prosperity. The New Qing History school argues that the interaction between politics and ethnicity was far more complex and that elements of these dynasties differed from and altered native Chinese traditions concerning imperial rule.
