A Dynasty in Decline: The Tang Empire’s Precarious State

The late Tang Dynasty presented a picture of imperial decay that would become familiar in Chinese history – a once-mighty empire now crumbling under corruption, military insubordination, and popular unrest. By the Xiantong era (860-874), the central government’s authority had significantly weakened, creating opportunities for regional warlords and rebel leaders to challenge imperial rule. The court’s extravagant spending, particularly under Emperor Yizong and his young successor Xizong, stood in stark contrast to the suffering of common people burdened by heavy taxes and natural disasters.

This period saw the emergence of two parallel threats that would ultimately contribute to the Tang collapse: the peasant rebellions led by Wang Xianzhi and Huang Chao in the central plains, and the growing power of Shatuo Turk military leaders like Li Guochang and his son Li Keyong in the northern frontier regions. The imperial court’s inability to decisively address either threat revealed the fundamental weaknesses of late Tang governance.

The Shatuo Turks: From Loyal Mercenaries to Rebel Warlords

The Shatuo Turks, originally a branch of the Western Turks, had migrated eastward and become important mercenary forces for the Tang Dynasty since their submission in the early 9th century. Settled primarily in the Daibei region (modern northern Shanxi and Inner Mongolia), these formidable cavalry troops had proven their worth in numerous campaigns, including the suppression of the Pang Xun rebellion in 868-869.

Li Guochang (originally named Zhu Xiechishi) emerged as the leader of these Shatuo forces, rewarded with military governorships for his service. However, as the central government’s control weakened, Li grew increasingly bold in his defiance. In 870, when appointed defense commissioner of Datong, he refused the post citing illness – an act of insubordination the weakened court was forced to tolerate due to its reliance on Shatuo cavalry.

The Young Emperor and the Court’s Disarray

The political situation deteriorated further when Emperor Xizong ascended the throne in 873 at just twelve years old. Dominated by powerful eunuchs like Tian Lingzi (whom the young emperor called “foster father”), the court became increasingly detached from the empire’s governance. The emperor’s preoccupation with entertainment and lavish spending on musicians and performers while ignoring state affairs became emblematic of the dynasty’s decline.

Contemporary records paint a bleak picture: “The emperor being young, governance fell to his ministers, with the southern officials and northern eunuchs constantly at odds. Since Emperor Yizong’s time, extravagance grew daily while military campaigns never ceased, and taxes became increasingly oppressive.” Natural disasters in the Guandong region went unreported by local officials, leaving desperate peasants to either starve or turn to banditry.

The Spark of Rebellion: Wang Xianzhi and Huang Chao

The powder keg ignited in 874 when Wang Xianzhi raised thousands of followers in Changyuan. A former salt smuggler like his more famous associate Huang Chao, Wang quickly captured Pu and Cao prefectures, defeating the Tianping military governor Xue Chong. Huang Chao, a failed examination candidate turned rebel leader, joined forces with Wang, their combined armies swelling to tens of thousands as desperate peasants flocked to their banners.

A contemporary rhyme captured the mood: “The golden toad glares with angry eyes, overturning Caozhou the world rebels.” The rebels adopted mobile tactics, avoiding decisive battles while capturing numerous prefectures across Shandong and Henan. By 876, they threatened the eastern capital Luoyang after capturing Ruzhou, sending shockwaves through the court.

The Northern Conspiracy: Li Keyong’s Rise

While the court struggled against the central plains rebels, northern military officers saw opportunity in the chaos. In 878, a group of officers including Li Jinzhong and Kang Junli conspired to overthrow their superior Duan Wenchu, the newly appointed Datong defense commissioner. They turned to Li Keyong, Li Guochang’s third son and a formidable warrior known as the “One-Eyed Dragon” for his distinctive appearance.

Li Keyong’s early life already bore signs of his future prominence. Born in 856 during a difficult delivery supposedly eased by supernatural intervention, he grew into an exceptional warrior even among the martial Shatuo. His military exploits during the Pang Xun rebellion at just fifteen earned him the nickname “Flying Tiger.” A famous anecdote tells of him shooting two eagles with a single arrow during a competition with Tatar warriors.

The Datong Mutiny and Its Aftermath

The conspirators seized Yunzhou (Datong) in early 878, killing Duan Wenchu and inviting Li Keyong to take command. When the court refused to recognize his position, both Li Keyong and his father openly rebelled, attacking neighboring regions. The imperial response proved ineffective as successive military governors failed to suppress the Shatuo forces.

The rebellion revealed the Tang military’s deep structural problems. Government troops frequently mutinied over pay disputes, sometimes killing their commanders. The Hedong (Shanxi) region saw particular turmoil, with five military governors appointed within eighteen months – several murdered by their own troops. The court’s authority had eroded to the point where it could only issue helpless proclamations: “The killing of the military governor was a momentary affair; all should calm themselves and not fear further trouble.”

The Shatuo Retreat and Temporary Defeat

By 880, coordinated attacks from multiple directions – including Youzhou (Lulong) forces under Li Keju and Tuyuhun tribes led by Helian Duo – finally defeated the Li family. After losing key battles at Yaoling Ridge and Xiongwu Army, Li Guochang and Li Keyong fled north to seek refuge with the Tatar tribes.

The court redistributed the Shatuo territories, appointing Helian Duo as Yunzhou prefect and other non-Shatuo leaders to neighboring regions. This marked the lowest point for Li Keyong, now an exile dependent on Tatar hospitality. However, his display of exceptional archery skills and hints at future service to the Tang prevented his Tatar hosts from eliminating him as Helian Duo had urged.

The Legacy of the Shatuo Rebellion

The Li family’s rebellion, though temporarily suppressed, demonstrated several critical weaknesses in late Tang rule:

1. The court’s over-reliance on and inability to control non-Han frontier forces
2. The growing autonomy of regional military governors
3. The imperial army’s declining discipline and effectiveness
4. The interconnected nature of different rebellions weakening coordinated responses

Li Keyong’s experience in exile proved formative. He learned that despite the Tang’s visible decline, the dynasty still commanded significant legitimacy and resources. This lesson would shape his subsequent career when he returned to play a pivotal role in the final decades of Tang rule and the subsequent Five Dynasties period.

The simultaneous challenges from peasant rebels like Huang Chao (who would sack Chang’an in 880) and military governors like the Lis stretched the Tang system beyond its breaking point. Within a generation, the dynasty would collapse, giving way to the tumultuous Five Dynasties and Ten Kingdoms period – where Li Keyong’s son Li Cunxu would eventually establish the Later Tang dynasty, partially restoring Tang institutions and culture.
