Biography
Family Background and Early Life
Liu Jiyuan was originally surnamed He. His mother, a woman of the Liu clan, was a daughter of Liu Min, the founder of Northern Han, who later changed his name to Liu Chong. She first married Xue Zhao and gave birth to Liu Jien. After Xue Zhao committed suicide, she remarried a man of the He family and gave birth to Liu Jiyuan. After Liu Jiyuan's parents both died, he and his maternal half-brother Liu Jien were adopted by their maternal uncle Liu Jun, a son of Liu Min. Through this combination of blood relationship and adoption, Liu Jiyuan grew up within the Northern Han court. During Liu Jun's reign, Liu Jien served as governor of Taiyuan, while Liu Jiyuan likewise grew up in the palace and was familiar with the core of Northern Han politics.
Accession and Domestic Government
In the seventh month of 968, the twelfth year of Tianhui, Liu Jun, Emperor Ruizong of Northern Han, died in grief as Song pressure intensified and the state's position deteriorated. Liu Jien succeeded him. In the ninth month of the same year, Liu Jien was assassinated by Hou Barong. The Minister of Works Guo Wuwei then installed Liu Jiyuan as emperor, and Liu Jiyuan adopted the era name Guangyun. From the outset he faced pressures both at home and abroad: the Northern Song was advancing from outside, while powerful officials struggled among themselves and military morale was unstable within the state.
Liu Jiyuan was cruel and suspicious. Soon after taking the throne, he believed Ma Feng's slanders and killed the general Zheng Jin. He also favored the eunuch Wei Degui, removed Wei Chou from command of the Tuyuhun troops, and transferred him to be prefect of Liao Prefecture. Several thousand Tuyuhun soldiers objected and asked that the order be rescinded, but Liu Jiyuan refused. Later, after hearing that Wei Chou had complained in private and fearing a mutiny, he sent men to kill him. General Li Yin protested on Wei Chou's behalf; Wei Degui then persuaded Liu Jiyuan to send Li Yin to Lan Prefecture under supervision, and Li Yin was soon killed as well. The Tuyuhun forces were a main component of the Northern Han army. The killing of their commanders shattered morale and greatly weakened the state's military strength.
To consolidate his throne, Liu Jiyuan also killed members of the ruling house. Liu Min had more than ten sons; among them Liu Gao, Liu Kai, Liu Qi, Liu Xi, and Liu Xian were still alive during Liu Jiyuan's reign. Except for Liu Xian, who escaped death by pretending to be foolish, the others were killed by Liu Jiyuan. Liu Jiyuan also suspected his adoptive mother Empress Guo, wife of Liu Jun, of causing the death of his wife Lady Duan. After becoming emperor, he ordered his favored retainer Fan Chao to strangle Empress Guo in front of Liu Jun's coffin. By this point, almost all remaining descendants of the Liu house had been wiped out.
Resistance to the Northern Song
In the spring of 969, the thirteenth year of Tianhui, Emperor Taizu of Song, Zhao Kuangyin, personally led an invasion of Northern Han. After repelling Liao relief forces, the Song army built long dikes to divert the Fen River and flood the city of Jinyang. Northern Han held the threatened city. By the intercalary fifth month, floodwaters broke through the southern wall of Jinyang and poured into the city. Chancellor Guo Wuwei attempted to surrender to the Song and was executed by Liu Jiyuan. Northern Han soldiers and civilians built barriers to close the breach. The weather was hot and rainy, Song troops were encamped on wet grassland and many suffered from diarrhea, while Khitan forces again moved to reinforce Northern Han. Emperor Taizu was forced to withdraw, abandoning large quantities of grain, military provisions, tea, and silk, all of which were taken by Northern Han.
In the first month of 979, the sixth year of Guangyun, Emperor Taizong of Song, Zhao Guangyi, having eliminated the southern separatist states, concentrated his forces for a personal campaign against Northern Han. He ordered Pan Mei and other commanders to lead several hundred thousand troops in a four-pronged attack on Taiyuan. Liu Jiyuan sent his son Liu Rang to the Khitan as a hostage to request military aid. On the sixteenth day of the third month, the Song commander Guo Jin decisively defeated the Liao relief army at Shiling Pass; the Liao commander Yelü Dilie was killed and more than ten thousand Liao troops were lost. After this defeat the Liao forces no longer dared to advance south, leaving Northern Han isolated. In the fourth month, Emperor Taizong advanced from Zhen Prefecture, captured Long Prefecture, and personally arrived beneath the walls of Taiyuan to supervise the siege.
Surrender to the Song and Later Years
Under intense Song attacks, on the first day of the fifth month the southwest outer enclosure of Jinyang fell. Fan Chao, Northern Han's commissioner of the Palace Communications Office, and Guo Wanchao, commander of the cavalry and infantry, successively surrendered. On the fourth day, Emperor Taizong personally drafted an edict urging Liu Jiyuan to surrender and promising that his wealth and rank would be preserved. Ma Feng, a retired deputy commissioner of military affairs, also entered the palace to urge surrender. With no remaining options, Liu Jiyuan sent a formal submission to Emperor Taizong.
Before dawn on the sixth day, Emperor Taizong and his generals held the surrender ceremony at Liancheng Terrace north of Taiyuan. Liu Jiyuan led his officials, dressed in white robes and gauze caps, and prostrated himself below the terrace to acknowledge guilt. Emperor Taizong immediately granted him the ranks and offices of Tejin, Acting Grand Preceptor, and General-in-Chief of the Right Guard and made him Duke of Pengcheng Commandery. He was given a fine residence in the capital and generous annual rewards. After the fall of Northern Han, Liu Jiyuan lived comfortably and at leisure. In 981 he was advanced to Duke of Pengcheng, and in 986 he became military governor of Baokang Army.
In 991, the second year of Chunhua, Liu Jiyuan became ill. Emperor Taizong sent eunuchs and imperial physicians to treat him. Before his death, Liu Jiyuan submitted a memorial entrusting his six-year-old son Sanzhu to the court. Emperor Taizong expressed sympathy and mourning, posthumously appointed Liu Jiyuan Secretariat Director, and made him Prince of Pengcheng Commandery; the government bore the expenses of his funeral. Sanzhu was given the name Shoujie, appointed deputy commissioner of the Western Capital workshops, allowed to reside at home, and provided with a stipend.
