The Fractured Landscape of Late Tang China

By the late 9th century, the Tang Dynasty (618–907) was crumbling under the weight of regional warlords who carved out autonomous fiefdoms. Two figures emerged as dominant rivals: Zhu Quanzhong, the ambitious warlord of Xuanwu Circuit, and Li Keyong, the Shatuo Turk leader governing Hedong. Their struggle would reshape northern China’s political landscape.

Zhu Quanzhong, originally a rebel under Huang Chao, defected to the Tang and was granted control of Xuanwu (modern Kaifeng). His early years were marked by strategic alliances, including a feigned kinship with Zhu Xuan and Zhu Jin, brothers ruling Tianping and Taining Circuits. Meanwhile, Li Keyong, the “One-Eyed Dragon,” commanded a formidable cavalry force from Hedong but faced logistical challenges due to his territory’s isolation.

The Breaking of Alliances and Military Escalation

The fragile peace shattered in 894 when Zhu Quanzhong, now secure in Bianzhou, turned on his former allies. Accusing the Zhu brothers of poaching his troops, he launched a campaign against Tianping and Taining. The brothers, outmatched, sought aid from Li Keyong, who saw an opportunity to curb Zhu’s expansion.

Li Keyong’s intervention was initially effective. In 894–895, his generals Shi Yan and Li Chengsi led cavalry raids that forced Zhu’s troops to retreat. However, a critical misstep in 896 doomed the alliance. Li Cunxin, a Hedong commander, allowed his troops to loot livestock from Weibo Circuit during a transit, provoking its governor Luo Hongxin. Zhu Quanzhong exploited this, convincing Luo that Li Keyong intended to annex Weibo. A night attack decimated Li Cunxin’s forces, severing Hedong’s access to the east.

The Battle of Huan River and Strategic Reverses

In 897, Li Keyong’s counteroffensive at Huan River ended disastrously. Zhu’s general Ge Congzhou devised a trap, digging hidden pits to cripple Hedong’s cavalry charges. Li Keyong’s son Li Luoluo was captured and executed, demoralizing the Hedong army. By year’s end, Zhu’s forces overran Tianping and Taining. Zhu Xuan was executed, while Zhu Jin fled to Yang Xingmi’s Wu Kingdom.

Li Keyong’s woes multiplied. His vassal Liu Rengong, ruler of Youzhou (modern Beijing), rebelled in 898, inflicting a crushing defeat at Mugajian Ravine. Simultaneously, Ge Congzhou seized three critical prefectures in Zhaoyi Circuit, exposing Hedong to direct attacks.

The Six-Pronged Invasion and Li Keyong’s Near Collapse

By 901, Zhu Quanzhong launched a coordinated six-route invasion of Hedong. Shi Shukun’s army reached Taiyuan’s gates, but torrential rains and relentless raids by Li Keyong’s generals forced a retreat. Though Hedong survived, its influence waned. Zhu consolidated control over Henan and Shandong, while Li Keyong’s allies defected or fell.

The Legacy of a Rivalry

Zhu Quanzhong’s triumph culminated in 907 with the founding of the Later Liang Dynasty, ending the Tang. Li Keyong, though reduced to a regional power, remained a symbol of resistance. His son Li Cunxu would later overthrow the Liang, avenging his father’s defeats.

This conflict underscored the era’s brutal pragmatism. Zhu’s mastery of deception and logistics contrasted with Li Keyong’s reliance on mobility and personal valor—a dichotomy that defined the Five Dynasties period. The struggle also highlighted the Tang’s fatal weakness: a central authority hollowed out by warlordism, leaving China fractured for decades.

Modern Reflections

Historians debate whether Li Keyong’s failure to consolidate Youzhou or ally with Liu Rengong cost him victory. Others note Zhu’s administrative reforms, which stabilized his territories. Their rivalry remains a case study in how personal ambition and shifting alliances shaped China’s transition from empire to fragmentation.

In popular culture, Li Keyong is often romanticized as the last loyal Tang general, while Zhu Quanzhong is vilified as a usurper. Yet both were products of an age where survival demanded ruthlessness—and where the line between warlord and emperor was perilously thin.
