Query: When was Liu Bei born?
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.
Liu Bei asked for and obtained Zhou Yu's permission to cover the rear and the flank of Zhou Yu's navy by taking the remaining four commanderies to the south of the Yangtze River from Cao Cao. There were hardly any troops left to defend the region, so all of the administrators of Cao Cao's four commanderies, including Jin Xuan at Wuling Commandery, Han Xuan at Changsha Commandery, Zhao Fan at Guiyang Commandery, and Liu Du at Lingling Commandery all surrendered without a fight. More importantly, Liu Bei's conquest of these commanderies was an integral portion of the Red Cliffs campaign as part of the goal of the allies. Liu Bei finally had a base of his own and he named Zhuge Liang as Military Adviser General of the Household (軍師中郎將) to oversee the administrative affairs of Changsha, Guiyang and Lingling.
Li Xi or Li Qi (李谿 per the "Zizhi Tongjian" and the "History of the Five Dynasties" or 李磎 per the "Old Book of Tang" and the "New Book of Tang") (d. June 4, 895), courtesy name Jingwang (景望), nicknamed Li Shulou (李書樓), was an official of the Chinese Tang Dynasty, serving briefly as a chancellor during the reign of Emperor Zhaozong. With imperial power dwindling, Li Xi's fellow chancellor Cui Zhaowei, who associated with the warlords Li Maozhen, Wang Xingyu, and Han Jian, encouraged Li Maozhen, Wang, and Han to march on the capital Chang'an. Once the three warlords arrived in Chang'an, they put Li Xi and his fellow chancellor Wei Zhaodu to death.
Li Deyu (; 787 – January 26, 850), courtesy name Wenrao (文饒), formally the Duke of Wei (衛公), was an official of the Chinese dynasty Tang Dynasty, serving as a chancellor during the reigns of brothers Emperor Wenzong and Emperor Wuzong and (briefly) their uncle Emperor Xuānzong. He was the leader of the so-called Li Faction in the decades-long Niu-Li Factional Struggles, and was particularly powerful during Emperor Wuzong's reign, dominating the court scene and guiding policies during the campaigns against the crumbling Huigu Khanate and against the warlord Liu Zhen. After Emperor Wuzong's death, Emperor Xuānzong, who had long despised him for his hold on power, had him demoted and banished, where he died in exile.
Li Deyu was born in 787, during the reign of Emperor Dezong. His grandfather Li Qiyun (李栖筠) served as the chief imperial censor, and his father Li Jifu would eventually serve as a chancellor during the reign of Emperor Dezong's grandson Emperor Xianzong. It was said that Li Deyu was ambitious in his youth and was studious, particularly concentrating on the "Book of Han" and the "Zuo Zhuan". He, however, did not want to submit to imperial examinations. During Emperor Dezong's "Zhenyuan" era (785-805), when Li Jifu was in exile, Li Deyu accompanied his father and did not seek an official career.
Li Yu (; 937 – 15 August 978), before 961 known as Li Congjia (李從嘉), also known as Li Houzhu (李後主; literally "Last Ruler Li" or "Last Lord Li"), was the third ruler of the Southern Tang state during imperial China's Five Dynasties and Ten Kingdoms period. He reigned from 961 until 976, when he was captured by the invading Song Dynasty armies which annexed his kingdom. He died by poison on orders of Emperor Taizong of Song after 2 years essentially as an exiled prisoner.
Li Jue (李珏 or 李玨) (784?-852?), courtesy name Daijia (待價), formally Duke Zhenmu of Zanhuang (贊皇貞穆公), was an official of the Chinese dynasty Tang Dynasty, serving as a chancellor during the reigns of Emperor Wenzong and (briefly) Emperor Wenzong's brother Emperor Wuzong. He was considered one of the leaders of the Niu Faction in the Niu-Li Factional Struggles.
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.
Li Zuo was born in 892, at the main palace at the Tang imperial capital Chang'an. His father Emperor Zhaozong was already emperor at that point, and he was Emperor Zhaozong's ninth son. His mother was Consort He, who had previously given birth to an older brother of his, Li Yu, Prince of De, who was Emperor Zhaozong's oldest son.
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.
Emperor Gaozu of Han (; 256 BCE – 1 June 195 BCE), born Liu Bang (劉邦), was the founder and first emperor of the Han dynasty, reigning from 202 – 195 BCE. He was one of the few dynasty founders in Chinese history who was born in a peasant family.
In 293 BC, East Zhou decided to ally itself with the states of Han and Wei, and sent troops to help attacking Qin. However, the combined forces of this alliance was destroyed at Yique by the young Qin general Bai Qi, with 240,000 men killed and their commander Gongsun Xi (公孫喜) captured and executed. After this loss, the East Zhou was unable to actively participate in future interstate struggles in any significant fashion.
In 256 BC, Duke Wu of West Zhou (西周武公) allied with other states to stop the Qin offensive on the Han city of Yangcheng. In retaliation, King Zhaoxiang of Qin sent general Jiu to invade West Zhou, successfully breaking into Wangcheng. The Duke Wu was taken to Xianyang to beg for mercy, conceding all his lands. Both King Nan and Duke Wu would die later that year, and the subsequent Duke of West Zhou, Duke Wen (西周文公), was exiled to Danhuju (憚狐聚). Because the Zhou royal court had fallen from power and King Nan had died without a successor, the Eastern Zhou Dynasty collapsed, ending 879 years of Zhou monarchy. The remaining East Zhou state was also conquered by Qin chancellor Lü Buwei seven years later in 249 BC during the reign of King Zhaoxiang's grandson King Zhuangxiang, after Duke Jing of East Zhou attempted to form an anti-Qin alliance with other states.
Li Ziming was born in Lijia Village, Ji County in Hebei province on June 25, 1902, and died on January 23, 1993, at the age of 90. He had a very cultured upbringing including the study of literature and martial arts, and was very talented at calligraphy and painting.
Lin Biao (December 5, 1907 – September 13, 1971) was a Marshal of the People's Republic of China who was pivotal in the Communist victory in the Chinese Civil War, especially in Northeast China. Lin was the general who commanded the decisive Liaoshen and Pingjin Campaigns, in which he co-led the Manchurian Field Army to victory and led the People's Liberation Army into Beijing. He crossed the Yangtze River in 1949, decisively defeated the Kuomintang and took control of the coastal provinces in Southeast China. He ranked third among the Ten Marshals. Zhu De and Peng Dehuai were considered senior to Lin, and Lin ranked directly ahead of He Long and Liu Bocheng.
Liu Yalou (; April 1910 – 7 May 1965) was a general in the People's Liberation Army of the People's Republic of China, first commander-in-chief of the People's Liberation Army Air Force, as well as chief of staff of Lin Biao's army group during the Chinese Civil War, occupied the whole of Manchuria in 1948 and captured 472,000 Nationalist troops in the Liaoshen Campaign.
Li Deyu () served as chancellor () during the Tang Dynasty. He was the leader and namesake of the Li faction during the Niu-Li Factional Struggles that pitted officials of humble and aristocratic origins against each other. Tang Emperor Xuānzong ended the struggles by handing complete defeat to the Li faction, demoting Li Deyu and sending him to exile in Hainan, where he held the position of census officer at Yai Prefecture (modern Haikou) and remained until his death.
Emperor Wuzong died in 846 and was succeeded by his uncle Emperor Xuānzong. As Emperor Xuānzong despised Li Deyu for his hold on power, he had Li Deyu removed from his chancellor post and sent out of the capital. Li Hui, meanwhile, remained as chancellor and oversaw the building of Emperor Wuzong's tomb, but in 847 was also sent out of the capital to serve as the military governor of Xichuan Circuit (西川, headquartered in modern Chengdu, Sichuan). That winter, with Li Deyu accused of having wrongly killed Wu Xiang (吳湘) on charges of corruption and forced marriage with a commoner — a case that both Li Hui and Zheng Ya were both involved in reviewing and affirming the death sentence of — Li Hui was demoted to be the governor (觀察使, "Guanchashi") of Hunan Circuit (湖南, headquartered in modern Changsha, Hunan) and prefect of its capital Tan Prefecture (in modern Changsha, Hunan). Emperor Xuānzong was then set to further give him the empty title of "Taizi Binke" (太子賓客), an advisor to the Crown Prince (there being no crown prince at the time) and having his office at the eastern capital Luoyang, when an imperial attendant objected to it as being an overly lenient punishment. Li Hui was thereafter demoted to be the prefect of Fu Prefecture (撫州, in modern Fuzhou, Jiangxi). (It was from Emperor Xuānzong's edict that it could be attested that Li Hui carried the title of Duke of Longxi, which was not otherwise mentioned in his biographies.)
The Battle of Jiangling was fought by the allied forces of Sun Quan and Liu Bei against Cao Cao during the late Eastern Han dynasty of China. The battle was an integral part of the Red Cliffs campaign, and was fought immediately after the Battle of Yiling in 208, and the preceding engagement at Wulin (烏林; in present-day Honghu, Hubei) on land and the marine Battle of Red Cliffs where Cao Cao's navy was destroyed. Note that the battle at Wulin was a byproduct of the Battle of Red Cliffs, and they were not the same battle.
Lü Meng was from Fupo County (富陂縣), Runan Commandery (汝南郡), which is located southeast of present-day Funan County, Anhui. His family migrated to the south of the Yangtze River when Lü Meng was young. Lü Meng lived with his brother-in-law, Deng Dang (鄧當), who served as a military officer under Sun Ce. When he was 14 or 15, he secretly followed Deng Dang to the battles against the Shanyue tribes. Deng Dang was shocked to see his teenage brother-in-law in battle, so he scolded Lü Meng and warned him to stop. Lü Meng refused to listen so Deng Dang told Lü Meng's mother about this. When she wanted to punish him, Lü Meng said: "It is difficult to survive in poverty. If we can prove ourselves through hard work, then wealth will come eventually. How can we catch the tiger cub if we don't enter the tiger's den?" Lü Meng's mother sighed and let him have his way.
The Han dynasty was founded by the peasant rebel leader (Liu Bang), known posthumously as Emperor Gao ("r". 202 –195 BC) or Gaodi. The longest reigning emperor of the dynasty was Emperor Wu ("r". 141–87 BC), or Wudi, who reigned for 54 years. The dynasty was briefly interrupted by the Xin dynasty of the former regent Wang Mang, but he was overthrown in 23 AD and the Han dynasty was reestablished by Liu Xiu, known posthumously as Emperor Guangwu (r. 25–57 AD), or Guangwu Di. The last Han emperor, Emperor Xian ("r". 189–220 AD), was a puppet monarch of Chancellor Cao Cao (155–220 AD), who dominated the court and was made King of Wei. In 220 AD, Cao's son Pi usurped the throne as Emperor Wen of Wei ("r". 220–226 AD) and ended the Han dynasty.
The short reigns of Emperor Wu's grandsons, Xiao Zhaoye and Xiao Zhaowen (his first son predeceased him), were dominated by Xiao Luan, Emperor's Wu's first cousin. He killed them in turn and crowned himself as Emperor Ming of Southern Qi. Using the government secretaries (典簽官), he slaughtered all the descendants of Emperors Gao and Wu. Emperor Ming soon became very ill and started following Daoism, changing his whole wardrobe to red. He also passed an edict making officials try to find silver fish (銀魚). He died in 498 and was succeeded by his son Xiao Baojuan, who killed high officials and governors at whim, sparking many revolts. The final revolt in 501 started after Xiao Baojun killed his prime minister Xiao Yi, leading his brother Xiao Yan to revolt under the banner of Xiao Baojun's brother who was declared Emperor He of Southern Qi. Xiao Baojun was killed by one of his generals during the siege of his capital at Jiankang, and after a short puppet reign by Emperor He, Xiao Yan overthrew the Southern Qi and established the Liang dynasty.
Liu Bei was a very distant descendant of Emperor Jing of Han. His father Liu Hong died when he was still very young and his mother made a living by selling straw sandals. In 175 Liu Bei was sent to study at the Taixue of Luoyang, where he became friends with Gongsun Zan. Liu Bei had very little interest in books but had a knack for fighting and inspired many young men to join him. With the support of two merchants, Zhang Shiping and Su Shuang, Liu Bei was able to create a sizable following including his long time friends Guan Yu and Zhang Fei. When the Yellow Turban Rebellion broke out in 184 Liu Bei led his troops against them under various commanders. He did well in both campaigns but was only rewarded with a very low position in the imperial service. He abandoned his post when an officer tried to reduce his position and joined Guanqiu Yi on an expedition against rebels in Danyang Commandery. For his service in that expedition he was rewarded with the post of assistant magistrate in a county in Pingyuan Commandery. When the anti-Dong Zhuo coalition formed, Liu Bei raised troops in their service, but soon afterwards left to join his friend Gongsun Zan in the north.
Liu Yan was born during the late Eastern Han dynasty in the Lu State (魯國), a princedom around present-day Qufu, Shandong. He was also a member of the Liu clan, the ruling house of the Han dynasty. When the warlord Liu Bei was the nominal governor of Yu Province during the early 190s, he met Liu Yan and recruited him as an assistant officer (從事). A charming and eloquent man with ties to the imperial clan, Liu Yan gained Liu Bei's favour and had accompanied the warlord on his exploits since then.
Liu Bei grew up in a poor family, having lost his father when he was still a child. To support themselves, Liu Bei and his mother sold shoes and straw-woven mats. Even so, Liu Bei was full of ambition from childhood: he once said to his peers, while under a tree that resembled the imperial chariot, that he desired to become an emperor. In 175, his mother sent him to study with Lu Zhi, a distinguished man from Zhuo Commandery. One of his fellow-students was Gongsun Zan, whom Liu Bei admired and treated as an elder brother, and another was his kinsman Liu Deran (劉德然). The adolescent Liu Bei was said to be unenthusiastic in studying and displayed interest in hunting, music and dressing. Concise in speech, calm in demeanour, and kind to his friends, Liu Bei was well liked by his contemporaries.
In 211, Liu Bei led an army to Yi Province (covering present-day Sichuan and Chongqing) to assist the governor Liu Zhang in countering the advances of a rival warlord, Zhang Lu of Hanzhong Commandery. He left Zhang Fei and others behind to guard Jing Province in his absence. Earlier in 209, Liu Bei married Sun Quan's younger sister Lady Sun to strengthen the alliance between him and Sun Quan. Because of her brother's strong influence, Lady Sun was arrogant and she allowed her close aides to behave lawlessly. Even Liu Bei was afraid of her. When Sun Quan heard that Liu Bei had left for Yi Province, he sent a vessel to Jing Province to fetch his sister home. Lady Sun attempted to bring along Liu Bei's son Liu Shan with her, but Zhang Fei and Zhao Yun led their men to stop her and managed to retrieve Liu Shan.
