during the Five Dynasties and Ten Kingdoms period, reigning from 951 until his death.
Early life
When Guo Wei was born in 904 in Yaoshan (尧山; in modern Longyao County, Hebei), the Tang Dynasty had disintegrated into regions controlled by warlords fighting amongst one another. Guo was just a toddler when his family moved to Taiyuan (in modern Shanxi), as his father Guo Jian (郭简) became the prefect (刺史) of Shunzhou (顺州, modern Shunyi District, Beijing), serving the Taiyuan-based warlord Li Keyong. Shortly afterwards, Guo Jian was killed by warlord Liu Rengong's forces which conquered Shunzhou, and before Guo Wei's deciduous teeth fell out his mother Lady Wang (王氏) also died. Orphaned, the young boy was raised by a distant relative, Lady Han (韩氏).
Guo Wei grew up into a muscular young man interested more in warfare than agriculture. He was also fond of drinking and gambling and frequently participated in brawls. When he was around 17, to escape arrest, he went to live with an acquaintance Gentleman Chang (常氏) in Huguan close to Luzhou (潞州, modern Changzhi, Shanxi), shortly before joining the army of Luzhou's interim regent (留后) Li Jitao. Li Jitao was serving Jin, ruled by Li Keyong's son Li Cunxu, but actually plotting to defect to the Later Liang, Jin's archenemy. He was therefore more interested in recruiting brave and talented soldiers than enforcing the law, so when an inebriated Guo stabbed a menacing marketplace butcher to death following an argument, he let Guo walk free, eventually summoning Guo back to serve him.
Career under Later Tang
In 923, Li Cunxu established the Later Tang and overthrew Later Liang. Li Jitao was killed a few months later and all of his former soldiers, including 19-year-old Guo Wei, were assigned to the cavalry rotations. As Guo was literate and good at mathematics, he soon became an officer. He delved into the available literature on military strategy as much as he could, particularly enjoying Spring and Autumn Annals for a Wider World (阃外春秋), recommended by a blood brother Li Qiong (李琼).
In 927, the Later Tang emperor Li Siyuan personally led an army to suppress Zhu Shouyin's rebellion. Guo Wei, then under the leadership of general Shi Jingtang, was among the first soldiers scaling the defensive wall of Xun (in modern Henan). Shi saw Guo's literary talents and tasked him to manage military records. Guo proved very popular among generals and ministers.
Career under Later Jin
Later Tang was replaced by the Later Jin in 936.
Career under Later Han
The Later Han was founded by a Shatuo Turk by the name of Liu Zhiyuan, posthumously known as Gaozu of Later Han. Guo Wei was already familiar with life under the Shatuo Turks as he had lived under their rule since he was nineteen years old. He served as the Assistant Military Commissioner to the founder of the Later Han. However, when a teenager assumed the throne in 948, court intrigue enabled Guo to usurp the throne in a coup and declare himself the founding Emperor of the Later Zhou Dynasty on New Year』s Day in 951 (11 February in the modern calendar).
Reign
He was the first Han Chinese Emperor in northern China since 923. His rule was able and he passed reforms that attempted to relieve pressures on China』s massive peasantry. His rule was vigorous and well-organized. However, he died from an illness three years into his reign in 954.
