Liang Shidu

Biography

Rebellion and Regional Rule

Liang Shidu came from a powerful local family in Shuofang and served the Sui as a commander of the Eagle-Swift Army. In 617, he rebelled, killed the commandery official Tang Shizong, seized Xiazhou, and declared himself Grand Chancellor. He then established ties with the Eastern Turks and gained control of Diaoyin, Honghua, and Yan’an, expanding his authority around Shuofang.

Establishment of the Liang Regime

Liang Shidu proclaimed himself emperor, established the Liang regime, and adopted the era name Yonglong. He relied on the Eastern Turkic khagan Shibi for military support and conducted campaigns southward. After the Tang consolidated control over the Guanzhong region and its surroundings, Liang continued to hold Shuofang and remained in opposition to Tang forces.

Defeat and Death

In the early Zhenguan era, the decline of Eastern Turkic power left Liang Shidu increasingly isolated. Emperor Taizong sent envoys to urge him to submit, but Liang refused. In 628, the Tang court dispatched generals including Chai Shao against the Liang regime. Liang was killed by his cousin Liang Luoren, who delivered his head to the Tang army. The Liang regime then collapsed.

Major Activities

Establishment of the Liang Regime

After rebelling at the end of the Sui, Liang Shidu seized Xiazhou and surrounding territory, proclaimed himself emperor, and founded the Liang regime under the era name Yonglong. With Eastern Turkic support, the regime remained part of the regional balance of power in the northwest during the Sui–Tang transition.

Resistance to Tang Unification

Liang Shidu relied on Turkic support to maintain his rule in Shuofang and refused Emperor Taizong’s offer of submission. After the Tang unified neighboring regions, it launched a campaign in 628 and eliminated the Liang regime.

The Rising, the Imperial Title and the Turkic Alliance

Liang Shidu's family had long been magnates of Shuofang, and under the Sui he was a commandant of an eagle-soaring office; dismissed from office, he gathered followers and turned bandit. On the first day of the second month of the thirteenth year of Daye, 617, he killed Tang Shizong, deputy of Shuofang commandery, and rose in arms there, calling himself grand chancellor; fighting the Sui general Zhang Shilong he defeated him, and in the third month he took the commanderies of Diaoyin, Honghua and Yan'an and took the imperial title with the dynastic name Liang and the era name Yonglong, and when he dug the earth to bury jade he found a seal, which he took for a sign. He allied with the Turks to the north, and the Shibi qaghan sent him a wolf's-head banner and the titles of Dadu Bilge Qaghan and Heaven-understanding Son of Heaven, whereupon Liang Shidu led the Turkic troops to seize the lands south of the river. In the seventh month of the first year of Wude, 618, he invaded Lingzhou and was beaten by the cavalry general Lin Xingcan; in the third month of the second year, 619, he invaded Lingzhou again and was driven off by the chief administrator Yang Ze; and later, encamped with more than a thousand Turkic horse, he was routed by Duan Decao, who pursued him two hundred li and took many prisoners. In fear Liang Shidu sent his minister of the secretariat Lu Jilan to persuade the Chuluo qaghan that, after the fall of the Sui, the central plain had split into small states all of whom attached themselves to the Turks, that Tang was growing stronger and would next be the Turks' enemy, and that he would serve as guide; the qaghan accepted and divided his forces to come south, but he died soon after, and before the troops set out Liang Shidu was routed again by Duan Decao.

His Fall

His officers Xin Liaor'er and Li Zhengbao plotted to seize him and submit, but the plot was discovered and Li Zhengbao came over to Tang alone. The Tang court, judging Liang Shidu's position more perilous, sent envoys to urge him to submit, which he refused; it then ordered the chief administrator of Xiazhou, Liu Min, and the assistant Liu Lancheng to work for the seizure of his land, using double agents and trampling his crops, so that the city's stores were empty. In the second year of Zhenguan, 628, Liu Min and Liu Lancheng memorialised that he could be taken, and Chai Shao and others were ordered to attack together; the Xieli qaghan sent picked cavalry to his aid, but heavy snow fell and the horses and sheep froze, and Chai Shao beat them and pressed on to the walls. Liang Shidu, in extremity, was killed by his cousin Liang Luoren, who submitted, and the state of Liang came to an end after twelve years, the Tang making its land into Xiazhou.

Personal Relations

• Liang Luoren: Cousin who killed Liang Shidu during the fall of the Liang regime and delivered his head to the Tang forces.
• Shibi Qaghan: Eastern Turkic ruler who supported Liang Shidu and granted him a title.
• Chai Shao: Tang general who took part in the 628 campaign against the Liang regime.

Historical Assessment

Sui–Tang Transition

Liang Shidu used his regional base and support from the Eastern Turks to establish a regime in Shuofang at the end of the Sui. During the Tang unification, he was one of the principal regional opponents in the northwest.

Later Assessments

Later histories discuss Liang Shidu mainly in the context of the warlord conflicts at the end of the Sui and the Tang’s early unification campaigns. They emphasize his reliance on Turkic support and the eventual defeat of his regime by the Tang.

Modern Scholarship

Modern scholarship examines Liang Shidu in relation to regional regimes at the Sui–Tang transition, relations between the Eastern Turks and Chinese states, and the wars of early Tang unification. Studies focus on how Shuofang’s geography shaped the regime’s survival and the Tang court’s northwestern strategy.
