A series of three military campaigns launched by Huan Wen, a powerful general and de facto ruler of the Eastern Jin dynasty, between 354 and 369 CE, aimed at recovering the Central Plains from non-Han regimes that had occupied northern China after the collapse of Western Jin.
The three expeditions were:
- In 354 CE (the 10th year of Yonghe), Huan Wen attacked Former Qin, ruled by Fu Jian (note: actually Fu Jian’s predecessor Fu Jian [different character] or Fu Sheng – historical sources vary; the ruler at the time was Fu Jian of Former Qin, though often confused with the later, more famous Fu Jian who ruled during the Fei River era). His forces advanced deep into Guanzhong (the Wei River valley) but ultimately withdrew due to supply shortages and stiff resistance.
- In 356 CE (Yonghe 12), he campaigned against the Qiang chieftain Yao Xiang (father of Yao Chang, founder of Later Qin), recapturing the symbolic former capital Luoyang. He briefly restored Jin authority there and even repaired imperial tombs, but could not hold the city long-term due to logistical constraints and court opposition.
- In 369 CE (the 4th year of Taihe), Huan Wen launched his largest expedition against the Former Yan regime of the Murong clan. Advancing along the Yellow River, he initially achieved success but was decisively defeated at the Battle of Fangtou when Former Yan, aided by Former Qin, cut off his supply lines. The campaign ended in a disastrous retreat.
Although none of these campaigns resulted in lasting territorial gains, they inflicted significant blows on the northern regimes, demonstrated Eastern Jin’s residual military capability, and – most importantly – greatly enhanced Huan Wen’s personal prestige and political power. His repeated calls to “restore the Central Plains” also served as a pretext to consolidate control over the Jin court, eventually leading him to pressure the emperor for the Nine Bestowments – a traditional prelude to usurpation – though he died before seizing the throne.
