The Shunzhi Emperor (15 March 1638 – 5 February 1661), personal name Fulin, was the second emperor of the Qing dynasty, and the first Qing emperor to rule over China proper. Upon the death of his father Hong Taiji, a committee of Manchu princes chose the 5-year-old Fulin as successor. The princes also appointed two co-regents: Dorgon, the 14th son of Nurhaci, and Jirgalang, one of Nurhaci's nephews, both of whom were members of the Aisin-Gioro clan. In November 1644, the Shunzhi Emperor was enthroned as emperor of China in Beijing.
From 1643 to 1650, political power lay mostly in the hands of the prince regent Dorgon. Under his leadership, the Qing conquered most of the territory of the fallen Ming dynasty, chased Ming loyalist regimes deep into the southwestern provinces, and established the basis of Qing rule over China proper despite highly unpopular policies such as the hair cutting edict of 1645, which forced all Qing male subjects to shave their forehead and braid their remaining hair into a queue resembling that of the Manchus. After Dorgon's death on the last day of 1650, the young Shunzhi Emperor started to rule personally. He tried, with mixed success, to fight corruption and to reduce the political influence of the Manchu nobility. In the 1650s, he faced a resurgence of Ming loyalist resistance, but by 1661 his armies had defeated the Qing's last enemies, Koxinga and the Prince of Gui, both of whom would succumb the following year.
The Shunzhi Emperor died at the age of 22 of smallpox, a disease endemic in China, but against which the Manchus had no immunity. He was succeeded by his third son, the Kangxi Emperor, who went on to reign for sixty years. Because fewer documents have survived from the Shunzhi era than from later eras of the Qing dynasty, this era is a relatively little-known period of Qing history.
In the 1580s, when China was ruled by the Ming dynasty (1368–1644), a number of Jurchen tribes lived in Manchuria. In a series of campaigns from the 1580s to the 1610s, Nurhaci (1559–1626), the leader of the Jianzhou Jurchens, unified most Jurchen tribes under his rule. One of his most important reforms was to integrate Jurchen clans under flags of four different colors—yellow, white, red, and blue—each further subdivided into two to form an encompassing social and military system known as the Eight Banners. Nurhaci gave control of these Banners to his sons and grandsons. Around 1612, Nurhaci renamed his clan Aisin Gioro ("golden Gioro" in the Manchu language), both to distinguish his family from other Gioro lines and to allude to an earlier dynasty that had been founded by Jurchens, the Jin ("golden") dynasty that had ruled northern China from 1115 to 1234. In 1616 Nurhaci formally announced the foundation of the Later Jin dynasty, effectively declaring his independence from the Ming. Over the next few years he wrested most major cities in Liaodong from Ming control. His string of victories ended in February 1626 at the siege of Ningyuan, where Ming commander Yuan Chonghuan defeated him with the help of recently acquired Portuguese cannon. Probably wounded during the battle, Nurhaci died a few months later.
Nurhaci's son and successor Hong Taiji (1592–1643) continued his father's state-building efforts: he concentrated power into his own hands, modeled the Later Jin's government institutions on Chinese ones, and integrated Mongol allies and surrendered Chinese troops into the Eight Banners. In 1629 he led an incursion to the outskirts of Beijing, during which he captured Chinese craftsmen who knew how to cast Portuguese cannon. In 1635 Hong Taiji renamed the Jurchens the "Manchus", and in 1636 changed the name of his polity from "Later Jin" to "Qing". After capturing the last remaining Ming cities in Liaodong, by 1643 the Qing were preparing to attack the struggling Ming dynasty, which was crumbling under the combined weight of financial bankruptcy, devastating epidemics, and large-scale bandit uprisings fed by widespread starvation.
When Hong Taiji died on 21 September 1643 without having named a successor, the fledgling Qing state faced a possibly serious crisis. Several contenders—namely Nurhaci's second and eldest surviving son Daišan, Nurhaci's fourteenth and fifteenth sons Dorgon and Dodo (both born to the same mother), and Hong Taiji's eldest son Hooge—started to vie for the throne. With his brothers Dodo and Ajige, Dorgon (31 years old) controlled the Plain and Bordered White Banners, Daišan (60) was in charge of the two Red Banners, whereas Hooge (34) had the loyalty of his father's two Yellow Banners.
The decision about who would become the new Qing emperor fell to the Deliberative Council of Princes and Ministers, which was the Manchus' main policymaking body until the emergence of the Grand Council in the 1720s. Many Manchu princes argued that Dorgon, a proven military leader, should become the new emperor, but Dorgon refused and insisted that one of Hong Taiji's sons should succeed his father. To recognize Dorgon's authority while keeping the throne in Hong Taiji's descent line, the members of the council named Hong Taiji's ninth son, Fulin, as the new emperor, but decided that Dorgon and Jirgalang (a nephew of Nurhaci who controlled the Bordered Blue Banner) would act as the five-year-old child's regents. Fulin was officially crowned emperor of the Qing dynasty on 8 October 1643; it was decided that he would reign under the era name "Shunzhi." Because the Shunzhi reign is not well documented, it constitutes a relatively little-known period of Qing history.
On 17 February 1644, Jirgalang, who was a capable military leader but looked uninterested in managing state affairs, willingly yielded control of all official matters to Dorgon. After an alleged plot by Hooge to undermine the regency was exposed on 6 May of that year, Hooge was stripped of his title of Imperial Prince and his co-conspirators were executed. Dorgon soon replaced Hooge's supporters (mostly from the Yellow Banners) with his own, thus gaining closer control of two more Banners. By early June 1644, he was in firm control of the Qing government and its military.
In early 1644, just as Dorgon and his advisors were pondering how to attack the Ming, peasant rebellions were dangerously approaching Beijing. On 24 April of that year, rebel leader Li Zicheng breached the walls of the Ming capital, pushing the Chongzhen Emperor to hang himself on a hill behind the Forbidden City. Hearing the news, Dorgon's Chinese advisors Hong Chengchou and Fan Wencheng (范文程; 1597–1666) urged the Manchu prince to seize this opportunity to present themselves as avengers of the fallen Ming and to claim the Mandate of Heaven for the Qing. The last obstacle between Dorgon and Beijing was Ming general Wu Sangui, who was garrisoned at Shanhai Pass at the eastern end of the Great Wall. Himself caught between the Manchus and Li Zicheng's forces, Wu requested Dorgon's help in ousting the bandits and restoring the Ming. When Dorgon asked Wu to work for the Qing instead, Wu had little choice but to accept. Aided by Wu Sangui's elite soldiers, who fought the rebel army for hours before Dorgon finally chose to intervene with his cavalry, the Qing won a decisive victory against Li Zicheng at the Battle of Shanhai Pass on 27 May. Li's defeated troops looted Beijing for several days until Li left the capital on 4 June with all the wealth he could carry.
After six weeks of mistreatment at the hands of rebel troops, the Beijing population sent a party of elders and officials to greet their liberators on 5 June. They were startled when, instead of meeting Wu Sangui and the Ming heir apparent, they saw Dorgon, a horseriding Manchu with his shaved forehead, present himself as the Prince Regent. In the midst of this upheaval, Dorgon installed himself in the Wuying Palace (武英殿), the only building that remained more or less intact after Li Zicheng had set fire to the palace complex on 3 June. Banner troops were ordered not to loot; their discipline made the transition to Qing rule "remarkably smooth." Yet at the same time as he claimed to have come to avenge the Ming, Dorgon ordered that all claimants to the Ming throne (including descendants of the last Ming emperor) should be executed along with their supporters.
