Query: Who was the first ruler of the Han dynasty?
Emperor Xian, the last emperor of the Han dynasty, was a descendant of the first emperor Liu Bang. Lasting for over 400 years (the first to last for more than a century), the Han Dynasty is regarded as one of the golden ages of Chinese history. The Han Dynasty was interrupted by the reign of the usurper Wang Mang, who declared the Xin dynasty (9–23 AD); on this basis, the Han Dynasty is generally divided into the Western Han (206 BC – 9 AD and 23–25 AD) and the Eastern Han (25–220 AD). The rulers of the Shu Han, one of the three successor states to the Han Dynasty during the Three Kingdoms period, were descended from the Han imperial family, and considered themselves a continuation of the Han Dynasty; they are included below.
In 221 BC, after the conquest of Qi, Ying Zheng proclaimed himself "Qin Shi Huang" (秦始皇; literally "First Emperor of Qin") and established the Qin dynasty. The Qin Empire was divided into 36 commanderies, with Xianyang as the imperial capital. Qin Shi Huang created a centralised state and empire that would become the bedrock of future Chinese dynasties. Although the Qin dynasty lasted 15 years only, its influence on Chinese history lasted for centuries to come.
The Warring States period in China drew to a close, with Qin Shi Huang conquering the six other nation-states and establishing the short-lived Qin dynasty, the first empire of China, which was followed in the same century by the long-lasting Han dynasty. However, a brief interregnum and civil war existed between the Qin and Han periods known as the Chu-Han contention, lasting until 202 BC with the ultimate victory of Liu Bang over Xiang Yu.
The Eastern Han (), also known as the Later Han (), formally began on 5 August 25, when Liu Xiu became Emperor Guangwu of Han. During the widespread rebellion against Wang Mang, the state of Goguryeo was free to raid Han's Korean commanderies; Han did not reaffirm its control over the region until AD 30. The Trưng Sisters of Vietnam rebelled against Han in AD 40. Their rebellion was crushed by Han general Ma Yuan (d. AD 49) in a campaign from AD 42–43. Wang Mang renewed hostilities against the Xiongnu, who were estranged from Han until their leader Bi (比), a rival claimant to the throne against his cousin Punu (蒲奴), submitted to Han as a tributary vassal in AD 50. This created two rival Xiongnu states: the Southern Xiongnu led by Bi, an ally of Han, and the Northern Xiongnu led by Punu, an enemy of Han.
In 221 BC, Ying Zheng, who was king of Qin at the time, proclaimed himself "Shi Huangdi" (始皇帝), which translates as "first emperor". "Huangdi" is composed of "huang" ("august one", 皇) and "di" ("sage-king", 帝), and referred to legendary/mythological sage-emperors living several millennia earlier, of which three were "huang" and five were "di". Thus Zheng became Qin Shi Huang, abolishing the system where the "huang"/"di" titles were reserved to dead and/or mythological rulers. Since then, the title "king" became a lower ranked title, and later divided into two grades. Although not as popular, the title 王 "wang" (king or prince) was still used by many monarchs and dynasties in China up to the Taipings in the 19th century. 王 is pronounced "vương" in Vietnamese, "ō" in Japanese, and "wang" in Korean.
The Warring States period ended in 221  after the state of Qin conquered the other six kingdoms, reunited China and established the dominant order of totalitarian autocracy. King Zheng of Qin proclaimed himself the First Emperor of the Qin dynasty. He enacted Qin's legalist reforms throughout China, notably the forced standardization of Chinese characters, measurements, road widths (i.e., cart axles' length), and currency. His dynasty also conquered the Yue tribes in Guangxi, Guangdong, and Vietnam. The Qin dynasty lasted only fifteen years, falling soon after the First Emperor's death, as his harsh authoritarian policies led to widespread rebellion.
Ruzi Ying (; 5 – 25), also known as Emperor Ruzi of Han and the personal name of Liu Ying (劉嬰), was the last emperor of the Chinese Western Han Dynasty from 6 CE to 9 CE. After Emperor Ai of Han and Emperor Ping died without heirs, Wang Mang chose the youngest of the available successors in order to maintain his power in the government. The child Ying was soon deposed by Wang Mang who declared the Xin Dynasty in place of the Han. During Xin Dynasty, Ying was under effective house arrest—so much so that as an adult, he did not even know the names of common animals. Before and after the Xin Dynasty was overthrown in 23 CE, many ambitious people claimed to be restoring the Han dynasty. In 25 CE, a rebellion against the temporary Gengshi Emperor used the former Emperor Ruzi as a focus, and when the rebellion was defeated, he was killed. He is often viewed as an innocent child who was the victim of tragic circumstances. (The expression "Emperor Ruzi" is a misnomer, as he never assumed the throne and was only named crown prince. Nevertheless, he is commonly referred to as such.)
For the first time, all Chinese lands were unified under one powerful ruler. In that same year, King Zheng proclaimed himself the "First Emperor" (始皇帝, "Shǐ Huángdì"), no longer a king in the old sense and now far surpassing the achievements of the old Zhou Dynasty rulers. The emperor made the He Shi Bi into the Imperial Seal, known as the "Heirloom Seal of the Realm". The words, "Having received the Mandate from Heaven, may (the emperor) lead a long and prosperous life." (受命於天，既壽永昌) were written by Prime Minister Li Si, and carved onto the seal by Sun Shou. The Seal was later passed from emperor to emperor for generations to come.
Qin founded the Qin dynasty in 221 BC, the first unified state in the region. Qin was succeeded by the Han dynasty in 206 BC, which established the province ("zhou") of Jingzhou in what is now Hubei and Hunan. The Qin and Han played an active role in the agricultural colonization of Hubei, maintaining a system of river dikes to protect farmland from summer floods. Towards the end of the Han dynasty in the beginning of the 3rd century, Jingzhou was ruled by regional warlord Liu Biao. After his death, Liu Biao's realm was surrendered by his successors to Cao Cao, a powerful warlord who had conquered nearly all of north China; but in the Battle of Red Cliffs, warlords Liu Bei and Sun Quan drove Cao Cao out of Jingzhou. Liu Bei then took control of Jingzhou; he went on to conquer Yizhou (the Sichuan Basin), but lost Jingzhou to Sun Quan; for the next few decades Jingzhou was controlled by the Wu Kingdom, ruled by Sun Quan and his successors.
The incursion of northern nomadic peoples into the region at the beginning of the 4th century began nearly three centuries of division into a nomad-ruled (but increasingly Sinicized) north and a Han Chinese-ruled south. Hubei, to the South, remained under southern rule for this entire period, until the unification of China by the Sui dynasty in 589. In 617 the Tang dynasty replaced Sui, and later on the Tang dynasty placed what is now Hubei under several circuits: Jiangnanxi Circuit in the south; Shannandong Circuit in the west, and Huainan Circuit in the east. After the Tang dynasty disintegrated in the 10th century, Hubei came under the control of several regional regimes: Jingnan in the center, Wu (later Southern Tang) to the east, and the Five Dynasties to the north.
This is a family tree for the Zhou dynasty, descendants of Duke Wu of Zhou who overthrew the last Shang ruler, thereby establishing the dynasty. Ruling from 1046 BC to 256 BC, it is notable as the longest dynasty in Chinese history, although the actual political and military control of China by the dynasty only lasted during the Western Zhou.
Although nominally under the rule of the Han, these kings were "de facto" independent and held considerable power within their territories, which could span several prefectures. As these kingdoms proved unruly, Liu Bang gradually subdued them through conspiracies, wars, and political maneuvering. Many were thus deposed and their kingdoms annexed by Han. As he was dying, the emperor ordered his ministers to swear an oath that only members of the royal house of Liu would be created as kings thenceforth. This injunction was violated by his widow, Empress Dowager Lü, who established several kingdoms with her own relatives as kings. They were destroyed after her death. The last king of the Western Han was Wu Zhu, King Jing of Changsha, who died without an heir in 157 BC. After that, there were no kings outside the royal clan until the end of the Han dynasty, when Cao Cao styled himself King of Wei in AD 216.
After the collapse of a united China under the Han dynasty in 220 due in large part to the Yellow Turban and the Five Pecks of Rice rebellions, China eventually coalesced into the Three Kingdoms. Of these, Cao Wei was the strongest, followed by Eastern Wu and Shu Han, but they were initially in a relatively stable formation. After a 249 coup by Sima Yi, the Sima family essentially controlled Cao Wei and the conquest of Shu by Wei rapidly followed.
The founder of the Ming dynasty was the Hongwu Emperor (21 October 1328 – 24 June 1398), who is also known variably by his personal name "Zhu Yuanzhang" and his temple name "Taizu of Ming" (literally "Great Ancestor of Ming"). He was the first emperor of the Ming dynasty. His regnal name, Hongwu, means "vastly martial".
The earliest Han expedition against the Dian Kingdom was led by Tang Meng in 135 BC, who established the Jianwei commandery in the region. Han dynasty observers saw Dian as a potential periphery that can absorbed by the empire beyond its frontiers. The Dian Kingdom was a major business center, linked by networks of prosperous trading routes to modern South and Southeast Asia. The trade connections were seen as attractive to the Han rulers as they desired to capture the areas prosperous maritime trade routes. These incentives motivated Emperor Han Wudi to attempt to extend the Han dynasty's control towards the Dian Kingdom to secure access to trade routes of various products such as silk and bamboo. Another incentive for the Han dynasty to expand against the Dian was the rich endowment of minerals and commodities such as iron, tine, silver, and lead that the territory of present-day Yunnan province offered. The Han had been attracted by the wealth of the kingdom, which traded cattle, fruit, horses, and slaves. Han soldiers opened up new trade routes, then expanded further north, toward an area near Shu. The commandery was later abandoned because of rising costs and the wars against the Xiongnu to the north of China. A later Chinese expedition, heading south to established a trade route after a report on Central Asian trade in 122 BC, was captured by the Dian for four years.
In 221 BC, the Qin state unified China by conquering the other six major states and established the Qin dynasty. However, the oppressive and extremely unpopular dynasty lasted only 14 years. In 209 BC, Chen Sheng and Wu Guang started the Dazexiang Uprising to overthrow the Qin dynasty.
Like their Ming (1368–1644) predecessors—but unlike the emperors of earlier dynasties like the Han (206 BCE–220 CE), Tang (618–907), and Song (960–1276)—Qing emperors used only one era name ("Shunzhi", "Qianlong", "Guangxu", etc.) for their entire reign, and are most commonly known by that name. Starting with Nurhaci, there were thirteen Qing rulers. Following the capture of Beijing in 1644, the Shunzhi Emperor (r. 1643–1661) became the first of the eleven Qing sovereigns to rule over China proper. At 61 years, the reign of the Kangxi Emperor (r. 1661–1722) was the longest, though his grandson, the Qianlong Emperor (r. 1735–1796), would have reigned even longer if he had not purposely ceded the throne to the Jiaqing Emperor (r. 1796–1820) in order not to reign longer than his grandfather. Qing emperors succeeded each other from father to son until the Tongzhi Emperor (r. 1861–1875), the 11th Qing ruler, died childess in 1875. The last two emperors were chosen by Empress Dowager Cixi from other branches of the imperial clan.
In 221 BC, Qin conquered the other six Warring States and founded the Qin dynasty; the He Shi Bi was then taken from the last duke of Zhao by Qin Shi Huangdi, who ordered it made into his imperial seal. The words, "Having received the Mandate from Heaven, may (the emperor) lead a long and prosperous life." (受命於天，既壽永昌) were written by Chancellor Li Si, and carved onto the seal by a man named Sun Shou. When Colonel Liu Bang attacked Xianyang, Ziying handed the jade over as a way of surrendering. The seal was to be passed on even as the dynasties rose and fell, but was lost between the Tang and Ming dynasties.
In 1368, a Han Chinese revolt known as the Red Turban Rebellion toppled the Mongol Yuan dynasty in China. Zhu Yuanzhang then established the Ming dynasty, ruling as the Hongwu Emperor (r. 1368–1398). It is not clear how much the early Ming court understood the civil war going on in Tibet between rival religious sects, but the first emperor was anxious to avoid the same trouble that Tibet had caused for the Tang dynasty. Instead of recognizing the Phagmodru ruler, the Hongwu Emperor sided with the Karmapa of the nearer Kham region and southeastern Tibet, sending envoys out in the winter of 1372–1373 to ask the Yuan officeholders to renew their titles for the new Ming court.
The kings from other dynasties (, "yìxìng wáng") were mostly remnants of the rebellion against the Qin dynasty. Following the Dazexiang Uprising, many noblemen rose in rebellion. Heirs, pretenders, and warlords called themselves "kings" and claimed sovereignty as continuations of the six states previously suppressed by Qin. Among these, Chu was the most powerful. However, its rightful ruler Huai II was assassinated on the orders of the warlord Xiang Yu and the 18 Kingdoms Xiang had formed rose in rebellion against him. Liu Bang, king of Han, ultimately defeated Chu and established the new Han dynasty. The kings who had sided with him were then permitted to maintain their titles and lands. A few other kingdoms were also formed by Liu Bang for generals and favorites.
This is a timeline of the Tang dynasty, which covers a period of roughly 289 years, from 618, when the dynasty was founded, to 907, when the last Tang emperor was deposed by the warlord Zhu Wen, who established the Later Liang dynasty, inaugurating the period of Five Dynasties and Ten Kingdoms. Information on areas and events relevant to the Tang dynasty such as the Wu interregnum, when Wu Zetian established her own Zhou dynasty, and other realms such as the Sui dynasty, Tibetan Empire, Three Kingdoms of Korea, Nanzhao, Japan and steppe nomads are also included where necessary.
Cao Cao died on 15 March 220. His son and successor, Cao Pi, soon forced Emperor Xian to abdicate the throne in favour of himself, ending the Han dynasty. Cao Pi established a new state known as Cao Wei (sometimes known inaccurately as the Kingdom of Wei), and he granted Emperor Xian a noble title – Duke of Shanyang (山陽公). The former Emperor Xian died in 234 and was buried with honours befitting an emperor, using Han ceremonies, and the then emperor of Wei, Cao Rui, was one of the mourners. As Emperor Xian's crown prince was already dead, his grandson Liu Kang (劉康) inherited his dukedom, which lasted for 75 more years and two more dukes, Liu Jin (劉瑾) and Liu Qiu (劉秋), until the line was exterminated by invading Xiongnu tribes in about 309, during the Jin dynasty. This practice of an emperor conferring hereditary nobility on his predecessor, from whom he usurped the throne, was known as "er wang san ke" (二王三恪).
Qin Shi Huang, the first ruler of the Qin dynasty, established China's imperial system of government in 221 BC after unifying the Seven Warring States through conquest, bringing to an end the Warring States period. For a time, the rulers of the warring states claimed nominal allegiance to an overlord king of the Zhou dynasty (c. 1050 – 256 BC), yet the Zhou kings' political power and prestige was less than that of later Chinese emperors. The imperial system fell apart after the fall of Qin in 206 BC. However, following Han's victory over Chu, the King of Han reestablished the imperial system and is known posthumously as Emperor Gaozu (r. 202–195 BC).
From the Shang to Sui (581–618 AD) dynasties, Chinese rulers (both kings and emperors) were referred to by their posthumous names in records and historical texts. Temple names, first used during the reign of Emperor Jing of Han ("r". 157–141 BC), were used exclusively in later records and historical texts when referring to emperors who reigned during the Tang (618–907 AD), Song (960–1279 AD), and Yuan (1271–1368 AD) dynasties. During the Ming (1368–1644 AD) and Qing (1644–1911 AD) dynasties, a single era name was used for each emperor's reign and became the preferred way to refer to Ming and Qing emperors in historical texts.
Liu Bei (; ; 161 – 10 June 223), courtesy name Xuande, was a warlord in the late Eastern Han dynasty who founded the state of Shu Han in the Three Kingdoms period and became its first ruler. Despite early failings compared to his rivals and lacking both the material resources and social status they commanded, he gathered support among disheartened Han loyalists who opposed Cao Cao, the warlord who controlled the Han central government and the figurehead Emperor Xian, and led a popular movement to restore the Han dynasty through this support. Liu Bei overcame his many defeats to carve out his own realm, which at its peak spanned present-day Sichuan, Chongqing, Guizhou, Hunan, and parts of Hubei and Gansu.
The short-lived Qin dynasty, started by Qin Shihuang (247–220 BCE), who reunified the Warring States and was the first Chinese ruler to use the title of "emperor", chose Legalism as the state ideology, banning and persecuting all other schools of thought. Confucianism was harshly suppressed, with the burning of Confucian classics and killing of scholars who espoused the Confucian cause. The state ritual of the Qin was indeed similar to that of the following Han dynasty. Qin Shihuang personally held sacrifices to Di at Mount Tai, a site dedicated to the worship of the supreme God since pre-Xia times, and in the suburbs of the capital Xianyang. The emperors of Qin also concentrated the cults of the five forms of God, previously held at different locations, in unified temple complexes.
