The Shun Dynasty’s Precarious Position After Shanhaiguan

The defeat of Li Zicheng’s Shun forces at the Battle of Shanhaiguan in late April 1644 sent shockwaves through northern China. This pivotal engagement, where Wu Sangui’s Ming loyalists joined forces with the invading Manchus to crush the peasant rebellion, marked the beginning of the Shun Dynasty’s rapid disintegration. As news of the military disaster spread through Shun-controlled territories, Ming loyalists among the gentry class saw their opportunity to strike.

These scholar-officials, who had grudgingly accepted Shun rule after the fall of Beijing, now mobilized to overthrow what they viewed as a temporary peasant regime. Most operated with limited information – some knew only that Wu Sangui had defeated Li Zicheng’s army; others understood the Manchus had entered China proper but believed Wu had merely borrowed Qing troops as auxiliaries. Their rallying cry became “Capture the Bandits and Restore the Ming” (擒贼复明), reflecting their ideological commitment to Ming restoration rather than Qing conquest.

The Shandong Uprising and the “Prince of Ji” Rebellion

On April 27, 1644, just days after the Shanhaiguan defeat, Ming loyalists in Shandong province launched their rebellion. Led by prominent local gentry including former Ming censor Lu Shiquan and scholar Cheng Xianzhen, the insurgents proclaimed Zhu Shuai, a minor Ming imperial clansman serving as magistrate of Xianghe county, as their nominal leader under the title “Prince of Ji” (济王). This carefully calculated move provided the rebellion with crucial legitimacy while avoiding direct challenge to potential Ming successors.

The Shandong uprising spread with remarkable speed. Within a month, rebel forces controlled forty-three counties across Shandong and southern Zhili (modern Hebei), including major cities like Jinan, Qingzhou, and the strategic Grand Canal hub of Linqing. Zhu Shuai’s proclamation made clear his movement’s limited aims: “I am but a distant relative of the imperial house…my duty lies in serving the sovereign and my parents…I have been mistakenly elevated to lead this campaign.” He explicitly referenced ongoing Ming resistance efforts under Shi Kefa in Nanjing and Wu Sangui’s alliance with Qing forces, positioning his rebellion as part of a broader Ming restoration rather than an independent power grab.

Administrative Challenges of the Loyalist Movement

The Shandong loyalists faced immediate governance challenges. Zhu Shuai’s administration, while styling itself as a Ming restoration government, operated in a legal gray area. They appointed officials with grandiose titles – the First Historical Archives preserves a memorial from one “Zhang Lütao, Director of the Ministry of War under the Prince of Ji’s government in Shandong” dated July 13, 1644. These appointments reflected both the practical needs of governing liberated territories and the political theater required to maintain gentry support.

Qing officials later accused Zhu of attempting to establish his own imperial claim, but contemporary documents suggest his administration carefully avoided claiming sovereign authority. The movement’s documents consistently referenced the possibility of a Ming imperial survivor (“we have heard our ruler may yet have a six-foot orphan”) and emphasized their role as placeholders until proper Ming authority could be restored. This delicate balancing act between asserting local control and maintaining ideological purity would ultimately contribute to the movement’s vulnerability when Qing forces turned their attention southward.

Strategic Blunders: Li Zicheng’s Fatal Withdrawal

While Ming loyalists reclaimed northern China county by county, Li Zicheng committed a series of catastrophic strategic errors. After retreating to Shanxi province, the Shun leader had a critical opportunity to regroup. The Qing forces had paused their advance, returning to Beijing to consolidate their hold on the capital region. Rather than fortifying Shanxi’s defenses by summoning reinforcements from Shaanxi and establishing a coordinated defense, Li inexplicably continued his withdrawal.

In early June 1644, Li and his top commanders, including Liu Zongmin, crossed the Yellow River back to their power base in Xi’an. Though he left garrisons at key Shanxi locations – Ma Chongxi at Guguan, Zhang Tianlin at Datong and Yanghe, Liu Zhong at Changzhi, and former Ming general Chen Yongfu at Taiyuan – these forces lacked unified command. The decentralized defense allowed Qing forces and their collaborators to pick off Shun positions one by one.

The Domino Effect: Defections and Collapse

The first major defection came on May 10, 1644, when former Ming general Jiang Xiang turned against the Shun garrison at Datong, killing commander Zhang Tianlin. Initially, Jiang framed his rebellion in Ming restoration terms, proclaiming his support for “Prince Zaoqiang” Zhu Dingshan as continuator of the Ming imperial line. However, by mid-June, under Qing pressure, Jiang abandoned the Ming pretense and pledged allegiance to the new dynasty.

This pattern repeated across northern China. Wu Weihua, brother of Ming Marquis Wu Weiying, volunteered to recruit former Ming officials for the Qing cause. Between June and August 1644, his efforts secured the surrender of numerous Shanxi counties north of Taiyuan. The most damaging defection came in August when Tang Tong, guarding the critical Shanxi-Shaanxi border region, switched sides. After initially using the Chongzhen reign period to signal Ming loyalty, Tang eventually accepted Qing authority, receiving the title “Marquis Dingxi” for his betrayal.

These defections had devastating consequences. Tang’s forces crossed the Yellow River, attacking Shun positions in northern Shaanxi and engaging Li Zicheng’s nephew Li Guo in a brutal fifteen-day battle. The Shun lost significant territory along both sides of the strategic waterway. Li Zicheng’s furious response – executing Tang’s family members – only underscored his regime’s crumbling authority.

The Fatal Flaw: Mishandling of Ming Defectors

The Shun Dynasty’s collapse revealed fundamental flaws in Li Zicheng’s approach to former Ming military leaders. From 1644 to 1645, virtually every Ming general who had joined the Shun cause ultimately betrayed it. This wholesale defection stemmed from Li’s failure to properly integrate these powerful military figures into his regime.

Unlike the Qing, who carefully managed their Chinese collaborators through a system of rewards, surveillance, and intermarriage with the Manchu elite, Li Zicheng allowed former Ming commanders to retain independent control of their forces. This policy of minimal interference, while perhaps intended to demonstrate confidence and win loyalty, instead created opportunities for mass betrayal when the military tide turned. The lesson was clear: in dynastic transitions, the management of defecting elites could determine a regime’s survival.

Legacy and Historical Significance

The loyalist revolts of 1644 represent a crucial but often overlooked chapter in the Ming-Qing transition. These uprisings demonstrate the enduring power of Ming legitimacy among northern Chinese elites, even after Beijing’s fall. The rapid spread of the “Prince of Ji” movement across dozens of counties reveals how shallow Shun authority had been outside its military strongholds.

Historically, these events underscore three critical factors in the Qing conquest: first, the importance of Wu Sangui’s defection in creating conditions for Shun collapse; second, the Qing’s skillful co-option of Ming restoration sentiment during their southward expansion; and third, the fatal weaknesses of Li Zicheng’s military-administrative system. The Shun’s inability to retain former Ming commanders prefigured similar challenges the Qing would later face with Wu Sangui and other Ming holdouts during the Revolt of the Three Feudatories.

Modern scholarship continues to reassess this turbulent period, with newly discovered documents in archives like the First Historical Archives providing fresh insights into the complex loyalties and calculations of participants. What emerges is not a simple narrative of Manchu conquest, but rather a multifaceted struggle where Ming restoration, peasant rebellion, and foreign invasion created competing visions for China’s future – visions whose resolution would shape Chinese history for centuries to come.
