In the year 197 AD, Yuan Shu, having declared himself Emperor of the short-lived Zhong dynasty, found his ambitions crumbling under a cascade of military defeats, diplomatic failures, and internal decay.
Once a powerful warlord controlling the fertile lands of Huai River region, Yuan Shu’s realm rapidly contracted due to betrayals, strategic miscalculations, and natural disaster. This pivotal year marked the beginning of his irreversible decline—a process vividly chronicled in both Romance of the Three Kingdoms and historical records such as the Records of the Three Kingdoms (Sanguozhi).
The fall of the southern empire
Yuan Shu’s self-proclamation as emperor in 197 AD was met with immediate backlash. His most devastating blow came from within: Sun Ce, the “Young Conqueror” and one of Yuan Shu’s key generals, declared independence and swiftly seized control of several commanderies in Jiangdong, including Wu, Kuaiji, and Danyang. This defection stripped Yuan Shu of his eastern territories and exposed his southern flank.
Desperate to rebuild his influence, Yuan Shu sought an alliance with Lü Bu, then ruling Xuzhou. He proposed a marriage alliance between his son and Lü Bu’s daughter. However, Chen Gui and Chen Deng, two of Lü Bu’s advisors, sabotaged the plan, convincing Lü Bu that Yuan Shu was untrustworthy. In a stunning reversal, Lü Bu not only refused the alliance, but also arrested Yuan Shu’s envoy, Han Yin, and sent him to Xuchang, where Cao Cao had him executed.
This humiliation was followed by military disaster. Yuan Shu launched a punitive expedition against Lü Bu, but his forces were decisively defeated. These consecutive setbacks shattered Yuan Shu’s prestige and morale.
Targeting the northwest
With his southern flank threatened by Sun Ce, his eastern alliance with Lü Bu broken, and his northern rival Cao Cao still reeling from defeat at Wancheng (January 197 AD), Yuan Shu turned his gaze northwest toward Yu Province (Yuzhou), controlled by Cao Cao.
Chen Kingdom (Chen State, a vassal of the Han dynasty), a prosperous and strategically vital region located just south of Xuchang, Cao Cao’s capital. Chen was ruled by King Liu Chong and administered by Prime Minister Luo Jun, both of whom had governed wisely for years, turning the kingdom into a haven of stability and wealth. Refugees from neighboring war-torn regions flocked to Chen, bolstering its population and military strength.
Due to insufficient provisions, Yuan Shu tried to borrow grain from Luo Jun, but Luo Jun refused to lend any grain. Aware that a direct assault would be costly, Yuan Shu opted for covert assassination.
Zhang Kai and the covert assassination
Yuan Shu chose Zhang Kai, a former Commander under Tao Qian, the Governor of Xu Province, to carry out the mission. Zhang Kai was no stranger to treachery: in 193 AD, he had been tasked with escorting Cao Cao’s father, Cao Song, to Yan Province. However, he murdered Cao Song and his family for their wealth and fled to Huainan, where Yuan Shu granted him refuge. And Cao Cao used this as a pretext to invade Xuzhou and carry out widespread slaughter.
Now, Yuan Shu sent Zhang Kai to Chen State under the pretext of conducting private business, requesting passage through the kingdom. Luo Jun, unaware of Zhang Kai’s true intentions, hosted a banquet in his honor, attended by King Liu Chong as well.
During the feast, Zhang Kai assassinated both Liu Chong and Luo Jun, plunging Chen State into chaos. With its leadership eliminated, the kingdom fell into disarray, allowing Yuan Shu to march his army across the Huai River and occupy the territory.
Cao Cao’s swift retaliation
The fall of Chen Kingdom brought Yuan Shu’s forces to the very doorstep of Xuchang. Recognizing the existential threat, Cao Cao personally led an expedition to reclaim the region.
Upon hearing of Cao Cao’s advance, Yuan Shu panicked. Yuan Shu had been defeated by Cao Cao before and knew he could not afford to confront him. What’s worse, at that time, he was badly short of provision to engage Cao Cao in a prolonged confrontation. So he abandoned his army and fled back across the Huai River to Shouchun, leaving behind his generals Qiao Rui, Zhang Xun, Li Feng, Liang Gang, and Yue Jiu to hold the line.
Cao Cao, commanding generals such as Yu Jin and Yue Jin, launched a fierce counteroffensive. The Yuan Shu forces, demoralized and leaderless, collapsed under pressure. Zhang Xun managed to escape back to Shouchun, but Qiao Rui, Li Feng, Liang Gang, and Yue Jiu were surrounded and defeated at Qi Yang of Ku County. The city fell quickly, and all four generals were executed.
With this victory, Chen Kingdom was fully restored to Cao Cao’s control, securing the southern approaches to Xuchang.
Famine and the End of an Empire
Though defeated by both Lü Bu and Cao Cao, Yuan Shu’s ultimate downfall was sealed not by war, but by nature. In the same year he declared himself emperor, the Jianghuai Region regions (areas between Huai River and Yangtze River) suffered a catastrophic drought.
Historical sources, including Chen Shou’s Sanguozhi, record that “the land was parched, grain prices soared to 50,000 coins per dan, and people resorted to cannibalism.” Yuan Shu’s already weakened state could not withstand this disaster. His army starved, his people rebelled, and his treasury collapsed.
By 199 AD, Yuan Shu, once a contender for the Mandate of Heaven, was a fugitive, begging for food and supplies. He died in despair, his imperial dream reduced to ashes.
Conclusion
Previously, Yuan Shu had already suffered from severe food shortages and requested grain supplies from Luo Jun, but his request was rejected. Therefore, he lacked the logistical capacity to engage Cao Cao in a prolonged confrontation over Chen Kingdom.
Yuan Shu misjudged the strategic situation. Taking advantage of repeated attacks by Zhang Xiu and Liu Biao on Ye County—where Cao Cao was preoccupied—he recklessly invaded Chen Kingdom despite his own internal weakness, under the mistaken belief that Cao Cao would not launch a counteroffensive against him.
Yuan Shu left Qiao Rui and other generals to defend Qiyang City while he fled back to Huainan to reorganize his defenses. When Qiyang fell, Cao Cao’s forces advanced rapidly, swiftly conquering Yuan Shu’s entire territory in Yu Province north of the Huai River. From then on, Yuan Shu was confined to the region south of the Huai, reduced to a defensive posture.
Yuan Shu’s campaign against Chen Kingdom in 197 AD was a last gasp of imperial ambition. From this point onward, Yuan Shu’s power was severely weakened. His troops dwindled and lost strength; he suffered the loss of several key generals; his reputation collapsed; many subordinates deserted or rebelled. He never recovered from this defeat and gradually declined into irrelevance.
