Dorgon (17 November 1612 – 31 December 1650) was a Manchu prince and regent of the early Qing dynasty. Born in the House of Aisin-Gioro as the 14th son of Nurhaci (the founder of the Later Jin dynasty, which was the predecessor of the Qing), Dorgon started his career in military campaigns against the Mongols, the Koreans, and the Ming dynasty during the reign of Hong Taiji (his eighth brother) who succeeded their father.
After Hong Taiji's death in 1643, he was involved in a power struggle against Hong Taiji's eldest son, Hooge, over the succession to the throne. Both of them eventually came to a compromise by backing out and letting Hong Taiji's ninth son, Fulin, become the emperor; Fulin was installed on the throne as the Shunzhi Emperor. Dorgon served as Prince-Regent from 1643 to 1650, throughout the Shunzhi Emperor's early reign. In 1645, he was given the honorary title "Emperor's Uncle and Prince-Regent" (皇叔父攝政王); the title was changed to "Emperor's Father and Prince-Regent" (皇父攝政王) in 1649.
Under Dorgon's regency, Qing forces occupied Beijing, the capital of the fallen Ming dynasty, and gradually conquered the rest of the Ming in a series of battles against Ming loyalists and other opposing forces around China. Dorgon also introduced the policy of forcing all Han Chinese men to shave the front of the heads and wear their hair in queues just like the Manchus. He died in 1650 during a hunting trip and was posthumously honoured as an emperor even though he was never an emperor during his lifetime. A year after Dorgon's death, however, the Shunzhi Emperor accused Dorgon of several crimes, stripped him of his titles, and ordered his remains to be exhumed and flogged in public. Dorgon was posthumously rehabilitated and restored of his honorary titles by the Qianlong Emperor in 1778.
Dorgon was born in the Manchu Aisin-Gioro clan as the 14th son of Nurhaci, the Khan of the Later Jin dynasty (the precursor to the Qing dynasty). His mother was Nurhaci's primary consort, Lady Abahai. Ajige and Dodo were his full brothers, and Hong Taiji was one of his half-brothers. Dorgon was one of the most influential among Nurhaci's sons, and his role was instrumental to the Qing occupation of Beijing, the capital of the fallen Ming dynasty, He fought against the Chahar Mongols in 1628 and 1635.
After Hong Taiji died in 1643, Dorgon became involved in a power struggle with Hong Taiji's eldest son, Hooge, over the succession to the throne. The conflict was resolved with a compromise – both backed out, and Hong Taiji's ninth son, Fulin, ascended the throne as the Shunzhi Emperor. Since the Shunzhi Emperor was only six years old at that time, Dorgon and his cousin Jirgalang were appointed co-regents.
In 1644. During Hong Taiji's reign, Dorgon participated in many military campaigns, including the conquests of Mongolia and Korea. On 17 February 1644, Jirgalang, who was a capable military leader but appeared 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 princely title 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.
Later, just as Dorgon and his advisors were pondering how to attack the Ming Empire, peasant rebellions were dangerously approaching Beijing. On 24 April of that year, rebel forces led by Li Zicheng breached the walls of the Ming capital. The last Ming emperor, the Chongzhen Emperor, hanged himself at a hill behind the Forbidden City. Hearing the news, Dorgon's Han Chinese advisors Hong Chengchou and Fan Wencheng (范文程; 1597–1666) urged the prince to seize this opportunity to present themselves as avengers of the fallen Ming Empire and claim the Mandate of Heaven for the Qing Empire. The last obstacle between Dorgon and Beijing was Wu Sangui, a former Ming general guarding the Shanhai Pass at the eastern end of the Great Wall.
Later, 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. 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.
Wu Sangui was caught between the Manchus and Li Zicheng's forces. He requested Dorgon's help in ousting the rebels and restoring the Ming Empire. When Dorgon asked Wu Sangui to work for the Qing Empire 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 army won a decisive victory against Li Zicheng at the Battle of Shanhai Pass on 27 May. Li Zicheng and his defeated troops looted Beijing for several days until they left the capital on 4 June with all the wealth they could carry. Historian Frederic Wakeman claims that by the late afternoon, Wu Sangui, who already defected to the Qing, found his army on the verge of defeat when a "violent sandstorm" started blowing on the battlefield. Dorgon have chosen this moment to intervene: galloping around Wu's right flank, the Qing cavalry charged Li's left wing at Yipianshi ("Lone Rock", north of Shanhai Pass). When they saw mounted warriors with shaved foreheads rushing at them out of the storm, Shun troops broke their lines, and With their left wing shattered, the Shun army was routed; thousands of Shun soldiers were massacred as they retreated chaotically toward Yongping.
Dorgon greeted the Shunzhi Emperor at the gates of Beijing on 19 October 1644. On 30 October the six-year-old monarch performed sacrifices to Heaven and Earth at the Altar of Heaven. The southern cadet branch of Confucius's descendants who held the title wujing boshi and the northern branch 65th generation descendant of Confucius to hold the title Duke Yansheng had their titles confirmed by the Shunzhi Emperor on 31 October. A formal ritual of enthronement for the Shunzhi Emperor was held on 8 November, during which the young emperor compared Dorgon's achievements to those of the Duke of Zhou, a revered regent of the Zhou dynasty. During the ceremony, Dorgon's official title was raised from "Prince Regent" to "Uncle and Prince Regent" (叔父攝政王), in which the Manchu term for "Uncle" (ecike) represented a rank higher than that of imperial prince. Three days later Dorgon's co-regent, Jirgalang, was demoted from "Prince Regent" to "Assistant Uncle Prince Regent" (輔政叔王). In June 1645, Dorgon eventually decreed that all official documents should refer to him as "Imperial Uncle Prince Regent" (皇叔父攝政王), leaving him one step short of claiming the throne for himself.
Dorgon gave a Manchu woman as a wife to the Han Chinese official Feng Quan, who had defected from the Ming to the Qing. The Manchu queue hairstyle was willingly adopted by Feng Quan before it was enforced on the Han population and Feng learned the Manchu language.
After six weeks of mistreatment at the hands of rebel troops, the residents of Beijing 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 horse-riding Manchu with the front half of his head shaved, present himself as the Prince-Regent. In the midst of this upheaval, Dorgon installed himself as Prince-Regent in Wuying Palace (武英殿), the only building that remained more or less intact after Li Zicheng had set fire to the Forbidden City 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 Empire, Dorgon ordered that all claimants to the Ming throne (including descendants of the last Ming emperor) should be executed along with their supporters.
