The Battle of Shanhaiguan (Shanhaikuan, or the Battle of
Shanhai Pass) on May 28, 1644, pitted Manzhu (Manchu) and imperial Chinese
troops against a force of rebel Chinese. It was the decisive event in the
replacement of the Ming dynasty by that of the Qing (Ch’ing).

The Ming period (1368-1644) saw major military and
administrative accomplishments and a great flowering in the arts, but by the
17th century the dynasty was under increasing pressure from the Japanese and
the Dutch and from rebellions within China, especially by the Manzhu. Descended
from the Mongols who had invaded China in the l2th century, the Manzhu in
Manchuria had become tributaries to the Ming dynasty.

In 1616 Manzhu leader Nurhachi, after uniting the Jurchen
(Nuzhen, Nu-chen) Mongolian tribes, proclaimed a new dynasty, the Later Jin
(Chin), at his capital of Liaoyang. For the next decade he waged war against
the Ming dynasty, capturing most of southern Manchuria and much of Mongolia.
Nurhachi, known by his successors as Emperor Taizu (Ch’ing T’ai-tsu), died in
1626. He was succeeded by his son Huang Taiji (Hung Taiji, sometimes
erroneously known in Western literature as Abahai). Huang Taiji ruled during
1626-1643. A highly effective administrator who was also respected for his
military abilities, he was also determined to expand the empire.

Huang Taiji established a base in Korea and repeatedly
raided into China. He also improved his army’s weapons, adding significant
numbers of gunpowder artillery to counter that of the Ming; his cavalry came to
be regarded as the best in Asia. In 1634 the Manzhus conquered inner (southern)
Mongolia and absorbed large numbers of the inhabitants into their forces.

At the same time, using the justification of nonpayment of
tribute and the failure of the Koreans to contribute troops against the Ming,
in 1636 Emperor Huang Taiji sent a large army into Korea and the next year
compelled the Joseon dynasty to formally renounce the Ming dynasty. During
1636-1644 a series of expeditions established Manzhu control over the Amur River
region. In 1636 at Mukden, Huang Taiji proclaimed the establishment of a new
imperial dynasty, the Qing, which was merely a renaming of the Later Jin
proclaimed by Nurhachi earlier. In 1643, however, Huang Taiji died, possibly at
the hands of one of his officials. His five-year-old son Shunzhi (Shun-chih)
became emperor (r. 1643-1661), although real authority was exercised by his
uncle, Prince Dorgon, as regent.

Meanwhile, from 1635 the Ming dynasty had been further
weakened by a number of internal rebellions. The greatest threat came from
rebel chieftain Li Zicheng (Li Tzu-ch’eng). In 1640 Li seized control of Henan
(Honan) and Shaanxi (Shensi) provinces south and southwest of Beijing,
respectively. In 1644 Li moved against the imperial capital of Beijing. Ming
emperor Chongzhen (Chu’ung-chen) then recalled two of his frontier armies,
including the one at Shanhaiguan commanded by Wu Sangui (Wu San-kuei). Sources
differ as to whether Wu refused to come to the aid of the emperor or his forces
simply arrived too late; in any case, Li seized control of Beijing on April 25,
1644. Just before the rebel troops took Beijing, Emperor Chongzhen committed

Wu learned of Emperor Chongzhen’s death while on his way to
Beijing and evidently considered surrendering to Li, in part because the rebel
had taken Wu’s father hostage. Nevertheless, Wu returned to Shanhaiguan. After
pillaging Beijing, on May 18 Li set out after Wu.

Wu meanwhile had decided that he would rather treat with the
Manzhus than with Li, so he called on Prince Dorgon to assist him in
overthrowing the rebel regime.

Li passed his army of some 100,000 men through Yongping
(Yang-p’ing) and almost to Shanhaiguan. Accounts differ as to what happened
next, but apparently on May 25, 1644, Wu appealed to Dorgon for immediate
assistance. Dorgon promptly responded, arriving at the strategic Shanhai Pass
at Shanhaiguan at the eastern end of the Great Wall on the next day with
100,000 men. Li may not have known the true strength of the forces against him
until the actual battle on May 28. Had he known that he was confronted by a
much larger and more experienced force, he probably would have refused battle.
The allies were also aided by a large sandstorm that morning that masked their
deployment. The Sino-Manzhu forces probably numbered 50,000 Manzhus and 40,000
Chinese. Wu may have been able to raise upwards of another 80,000 men in local
Chinese militia, but there is no proof that they participated in the battle. Li
probably commanded something on the order of 60,000 men.

The allies turned the battle when Wu’s veterans attacked the
rebel left. Sheer numbers told. Li’s army then fled the field. The allies broke
off the pursuit after a dozen miles. Li withdrew to Beijing but had neither the
supplies nor the forces to resist a siege. He had himself hastily proclaimed as
emperor on June 3 and then executed Wu’s father. Li stripped Beijing bare of
supply animals and anything of value and then withdrew the next day, leaving
behind a city in flames.

Wu hoped to establish himself as viceroy in a continuation
of the Ming dynasty, but Dorgon’s force was simply too powerful. Wu bowed to
the inevitable, agreeing to serve the Manzhus. Dorgon gave him the assignment
of hunting down Li, which Wu accomplished in 1645, executing Li.

Dorgon moved the Manzhu capital to Beijing and there
established the new dynasty of the Qing (1644-1911). The Manzhus adopted most
of the Ming administrative system and culture, and the new dynasty became one
of the greatest in Chinese history.
