Ming–Qing Transition

The transition from Ming to Qing, alternatively known as Ming–Qing transition or the Manchu conquest of China, from 1618 to 1683, saw the transition between two major dynasties in Chinese history. It was a decades-long conflict between the emerging Qing dynasty, the incumbent Ming dynasty, and several smaller factions (like the Shun dynasty and Xi dynasty). It ended with the consolidation of Qing rule, and the fall of the Ming and several other factions.

Overview

The transition from the Ming to Qing was a decades-long period of conflict between:

# the Qing dynasty, established by the Manchu clan Aisin Gioro in contemporary Northeast China;
# the Ming dynasty, the incumbent dynasty led by the Zhu clan;
# and various other rebel powers in China, such as the short-lived Xi dynasty led by Zhang Xianzhong and the short-lived Shun dynasty led by Li Zicheng.

Leading up to the Qing, in 1618, the Later Jin khan Nurhaci commissioned a document entitled the Seven Grievances, which enumerated grievances against the Ming. Many of the grievances dealt with conflicts against the Ming-backed Yehe clan of the Jurchens. Nurhaci's demand that the Ming pay tribute to him to redress the seven grievances was effectively a declaration of war, as the Ming were not willing to pay money to a former tributary. Shortly afterwards, Nurhaci rebelled against Ming rule in Liaoning.

At the same time, the Ming dynasty was fighting for its survival against fiscal turmoil and peasant rebellions. Han Chinese officials urged Nurhaci's successor Hong Taiji to crown himself emperor, which he did in 1636, declaring the new Qing dynasty. On 24 April 1644, Beijing fell to a rebel army led by Li Zicheng, a former minor Ming official who became the leader of the peasant revolt and then proclaimed the Shun dynasty. The last Ming emperor, the Chongzhen Emperor, hanged himself from the Zuihuai tree in the imperial garden outside the Forbidden City. When Li Zicheng moved against him, the Ming general Wu Sangui shifted his allegiance to the Qing. Li Zicheng was defeated at the Battle of Shanhai Pass by the joint forces of Wu Sangui and Manchu prince Dorgon. On 6 June, the mainly Han Chinese forces of Dorgon and Wu entered the capital.

The fall of the Ming dynasty was largely caused by a combination of factors. Scholars have argued that the fall of the Ming dynasty may have been partially caused by the droughts and famines caused by the Little Ice Age. Historian Kenneth Swope argues that one key factor was deteriorating relations between Ming Royalty and the Ming Empire's military leadership. Other factors include repeated military expeditions to the North, inflationary pressures caused by spending too much from the imperial treasury, natural disasters and epidemics of disease. Contributing further to the chaos was a peasant rebellion throughout the country in 1644 and a series of weak emperors. Ming power would hold out in what is now southern China for years, though eventually would be overtaken by the Qing forces.
Other authors have linked the fall of the Ming with the General Crisis affecting the Spanish Empire under Philip IV, the English Civil War and other polities.

However, the victory was far from complete as it required almost 40 more years before all of China was securely united under Qing rule. In 1661, the Kangxi Emperor ascended the throne, and in 1662 his regents launched the Great Clearance to defeat the resistance of Ming loyalists in South China. He then fought off several rebellions, such as the Revolt of the Three Feudatories led by Wu Sangui in southern China, starting in 1673, and then countered by launching a series of campaigns that expanded his empire. In 1662, Zheng Chenggong (Koxinga) drove out and defeated the Dutch and founded the Kingdom of Tungning in Taiwan, a Ming loyalist state with the goal of reunifying China. However, Tungning was defeated in 1683 at the Battle of Penghu by Han Chinese admiral Shi Lang, a former admiral under Koxinga.

The Qing victory was overwhelmingly the result of the defection of the Ming dynasty's Liaodong military establishment and other defectors, with the Manchu military playing a very minor role (see below for specific examples)...

Jurchens and the late Ming dynasty

The Manchus are sometimes described as a nomadic people, when in fact they were not nomads, but a sedentary agricultural people who lived in fixed villages, farmed crops, practiced hunting and mounted archery. Their main military formation was infantry wielding bows and arrows, swords, and pikes, while cavalry was kept in the rear.

Manchus were living in cities with walls surrounded by villages and adopting Han Chinese-style agriculture well before the Qing conquest of the Ming, and there was an established tradition of Han Chinese-Manchu mixing before 1644. The Han Chinese soldiers on the Liaodong frontier often mixed with non-Han tribesmen and were largely acculturated to their ways. The Jurchen Manchus accepted and assimilated Han soldiers who went over to them, and Han Chinese soldiers from Liaodong often adopted and used Manchu names. Indeed Nurhaci's secretary Dahai may have been one such individual.

In the late Ming dynasty, Ming army units had become dominated by officers who would spend long periods of 10 or 12 years in command instead of the usual practice of constant rotation, and the Central Military Command had lost much of its control over regional armies. ''Zongdu Junwu'', or Supreme Commanders, were appointed throughout the empire to oversee the fiscal and military affairs in the area of their jurisdiction. In the frontier areas these became increasingly autonomous, and especially in Liaodong, where military service and command became hereditary and vassalage-like personal bonds of loyalty grew between officers, their subordinates and troops. This military caste gravitated toward the Jurchen tribal chieftains rather than the bureaucrats of the capital.

The She-An Rebellion among the Yi people broke out in Sichuan in 1621 against the Ming, requiring suppression, which was completed in 1629. In the early 1640s, mass rebellions led by many rebel leaders broke out in northwestern China's province of Shaanxi and spread throughout China in the 1640s. Major battles included the sacking of Fengyang by Li Zicheng and Zhang Xianzhong and a battle in Kaifeng which led to the deliberately engineered 1642 Yellow River flood by the Ming governor in an attempt to stop Li Zicheng.

Initial Jurchen conquests

Conquest of Liaodong and other Jurchen tribes (1601–1626)

The Jianzhou Jurchen chief, Nurhaci, is retrospectively identified as the founder of the Qing dynasty. In 1589 the Ming dynasty appointed Nurhaci as paramount chieftain of the Yalu Region, believing that his tribe was too weak to gain hegemony over the larger Yehe and Hada. When the other tribes attacked him to check his power in 1591, he succeeded in defeating them and seized many of their warhorses.

In 1607 he declared himself ''Khan''. Upon the advice of an Erdeni, most likely a Chinese transfrontiersman, he proclaimed the Jin State, named after the Jurchen-led Jin dynasty that had ruled over northern China several centuries earlier. His unifying efforts gave the Jurchen the strength to assert themselves backed by an army consisting of majority Han Chinese defectors as well as Ming produced firearms. In May 1618, Nurhaci proclaimed his Seven Grievances against the Ming and departed his capital of Hetu Ala with 20,000 men. The army attacked and captured Fushun, located on the Hun River about 10 kilometers east of Shenyang.

The Hulun tribes, a powerful confederacy of Jurchen tribes, started recognizing the authority of Nurhaci by the beginning of the 17th century. In some cases, such as with Bujantai of the Ula, chieftains would attempt to reassert their independence and war would break out, but the Jianzhou Jurchens would defeat and assimilate all the tribes eventually (Hada 1601, Hoifa 1607, Ula 1613, Yehe 1619). The powerful Yehe Jurchens under Gintaisi united with the forces of the Ming dynasty to combat the rise of Nurhaci but Gintaisi was defeated and died in 1619. The fur-trapping Warka peoples near the Pacific coast were subjugated as tributary tribes from 1599 to 1641.

By summer 1621, the Ming's Liaodong fortress cities, Fushun, Shenyang, and Liaoyang, were all handed over to the Later Jin by traitors and defectors. Fushun's commander surrendered after a single attack when promised that his troops and their families would not be enslaved or forced to change any of their customs (including hairstyle), but rather given high office. Shenyang fell with the aid of Mongol Ming soldiers in the city; Liaoyang fell after traitors let down ropes for the Jurchens to climb the wall in the night. The Ming general Li Yongfang who surrendered the city of Fushun in what is now Liaoning province in China's northeast did so after Nurhaci gave him an Aisin Gioro princess in marriage and a noble title. The princess was one of Nurhaci's granddaughters. In April 1625, Nurhaci designated Shenyang the new capital city, which would hold that status until the Qing conquest of Beijing in 1644. In 1625, the Jurchens captured the port city of Lüshun, thus controlling the whole Liaodong peninsula.

When the Jurchens were reorganized by Nurhaci into the Eight Banners, many Manchu clans were artificially created from groups of unrelated people who would found a new Manchu clan (''mukun'') using a term of geographic origin such as a toponym for their ''hala'' (clan name). The irregularities over Jurchen and Manchu clan origin led to the Qing trying to document and systemize the creation of histories for Manchu clans, including manufacturing an entire legend around the origin of the Aisin Gioro clan by taking mythology from the northeast.

Nurhaci read the Chinese novels ''Romance of the Three Kingdoms'' and ''Water Margin'', learning all he knew about Chinese military and political strategies from them.

In February 1626, the Jurchens besieged Ningyuan but suffered a defeat in which Nurhaci was mortally wounded.

First Joseon campaign

The Later Jin had lost at the Battle of Ningyuan the previous year and their khan Nurhaci died from his wounds afterwards. Peace negotiations with the Ming after the battle delayed an aggressive Ming response to the Jurchen loss, and the Ming general Yuan Chonghuan was busy fortifying the border garrisons and training new musketeers. The new khan Hong Taiji was eager for a quick victory to consolidate his position as khan. By invading Joseon he also hoped to extract much-needed resources for his army and subjects, who had suffered in the war against the Ming.

In 1627, Hong Taiji dispatched princes Amin, Jirgalang, Ajige and Yoto to Joseon with 30,000 troops, under the guidance of Gang Hong-rip and Li Yongfang. The Jurchens met sharp resistance at the border towns but Joseon border garrisons were quickly defeated. The Jurchen army advanced into Uiju where Ming general Mao Wenlong was stationed, and Mao quickly fled with his men into the Bohai Sea. Next, the Jurchens attacked Anju. When it became clear that defeat was inevitable, the Anju garrisons committed suicide by blowing up their gunpowder storehouse. Pyongyang fell without a fight and the Jin army crossed the Taedong River. Joseon Korean King Injo asked the Ming to send cannons and hwagi rocket carts in addition to the Ming "southern army" to help against the 1627 Manchu invasion of Korea as Joseon forts fell and Joseon troops were wiped out.. He also said Korean commoners had to provide excessive rations to Ming general Mao Wenlong.

By this time news of the invasion had reached the Ming court, which immediately dispatched a relief contingent to Joseon, slowing the Jurchen advance into Hwangju. King Injo then dispatched an envoy to negotiate a peace treaty, but by the time the messenger returned, Injo had already fled from Hanseong to Ganghwa Island in panic.

Mongolia campaign (1625–1635)

The Khorchin Mongols allied with Nurhaci and the Jurchens in 1626, submitting to his rule for protection against the Khalkha Mongols and Chahar Mongols. Seven Khorchin nobles died at the hands of Khalkhas and Chahars in 1625. This started the Khorchin alliance with the Qing.

The Chahar Mongols were fought against by Dorgon in 1628 and 1635. An expedition against the Chahar Mongols in 1632 was ordered to establish a trading post at Zhangjiakou. The Qing defeated the armies of the Mongol khan Ligdan, who was allied to the Ming, bringing an end to his rule over the Northern Yuan. The defeat of Ligdan Khan in 1634, in addition to winning the allegiance of the Southern Mongol hordes, brought a vast supply of horses to the Qing, while denying the same supply to the Ming. The Qing also captured the Great Seal of the Mongol Khans, giving them the opportunity to portray themselves as heirs of the Yuan dynasty as well.

Hong Taiji and formation of the Qing dynasty

Hong Taiji was the eighth son of Nurhaci, whom he succeeded as the second ruler of the Later Jin dynasty in 1626. He organised imperial examinations to recruit scholar-officials from the Han Chinese, and adopted Chinese legal forms. He formed autonomous Han Chinese military colonies governed by Han Chinese officials, where Manchus were forbidden to trespass. Hong Taiji curtailed the power of the Manchu princes by relying on Han Chinese officials. He personally welcomed surrendered Ming commanders, eating side-by-side with them so as to build a rapport that was impossible with the Ming emperors. The Manchus, led by Prince Amin, expressed their displeasure at the situation by massacring the population of Qian'an and Yongping. Hong Taiji responded by arresting and imprisoning Amin, who later died in prison. He then implemented, on the urging of his Han Chinese advisors, Chinese-style Confucian education, and Ming-style government ministries. When Zhang Chun, a Ming commander, was captured but refused to defect, Hong Taiji personally served him with food to show his sincerity (Zhang still refused but was kept in a temple until his death). With the surrender of Dalinghe in 1631, the most capable army officers of the Ming became faithful followers of the new dynasty who would take over the preparation and planning of much of the war. From this episode onward, the Ming-Qing transition ceased to be an inter-nation conflict between Chinese and Manchus but rather a civil war between Liaodong and Beijing.

Meanwhile, in the Ming, the Wuqiao mutiny broke out in 1631, led by Kong Youde and Geng Zhongming. Undersupplied and underpaid soldiers mutinied against the Ming dynasty. They subsequently sailed across Bohai Gulf and defected to the Jurchens en masse. During the mutiny, they purged thousands of Southern Chinese, suspecting them to be loyal to the Ming.

Hong Taiji was reluctant to become Emperor of China. However, Han Chinese officials Ning Wanwo, Fan Wencheng, Ma Guozhu, Zu Kefa, Shen Peirui, and Zhang Wenheng urged him to declare himself as Emperor of China. On 14 May 1636, he accepted this advice, changing the name of his regime from the Later Jin to the Qing dynasty, and enthroning himself as Emperor of China in an elaborate Confucian ceremony.

Hong Taiji's renaming of the Jurchens to Manchus was meant to hide the fact that the ancestors of the Manchus, the Jianzhou Jurchens, were ruled by the Han Chinese. The Qing dynasty carefully hid the two original editions of the books of "''Qing Taizu Wu Huangdi Shilu''" and the "''Manzhou Shilu Tu''" (Taizu Shilu Tu) in the Qing palace, forbidding them from public view, because they showed that the Manchu Aisin-Gioro family had been ruled by the Ming dynasty. In the Ming period, the Koreans of Joseon referred to the Jurchen-inhabited lands north of the Korean peninsula, above the rivers Yalu and Tumen, to be part of Ming China, as the "superior country" (sangguk), the name they used to refer to Ming China. The Qing deliberately excluded references and information from the '' History of Ming'' that showed the Jurchens (Manchus) as subservient to the Ming dynasty, to hide their former subservient relationship to the Ming. The '' Veritable Records of Ming'' were not used to source the ''History of Ming'' because of this. Refusing to mention in the Mingshi that the Qing founders were Ming China's subjects was meant to avoid the accusation of rebellion.

Han–Manchu marriages

Han Chinese generals who defected to the Manchus were often given women from the imperial Aisin-Gioro family in marriage. Manchu Aisin-Gioro princesses were also married to Han Chinese officials' sons. The Manchu leader Nurhaci married one of his granddaughters ( Abatai's daughter) to the Ming general Li Yongfang after he surrendered Fushun in Liaoning to the Manchus in 1618. The offspring of Li Yongfang received the "Third Class Baron" () title. Li Yongfang was the great-great-great-grandfather of Li Shiyao. The 4th daughter of Kangxi was wedded to Sun Cheng'en, son of the Han Chinese Sun Sike. Other Aisin-Gioro women married the sons of the Han Chinese generals Geng Jimao, Shang Kexi, and Wu Sangui. Meanwhile, the ordinary soldiers who defected were often given non-royal Manchu women as wives, and a mass marriage of Han Chinese officers and officials to Manchu women numbering 1,000 couples was arranged by Prince Yoto and Khan Hong Taiji in 1632 to promote harmony between the two ethnic groups.

This policy, which began before the invasion of 1644, was continued after it. A 1648 decree from Shunzhi allowed Han Chinese civilian men to marry Manchu women from the Banners with the permission of the Board of Revenue if they were registered daughters of officials or commoners or the permission of their banner company captain if they were unregistered commoners, and it was only later in the dynasty that these policies allowing intermarriage were done away with. The decree was formulated by Prince Dorgon. In the beginning of the Qing dynasty the Qing government supported Han Chinese defectors weddings to Manchu girls. Han Chinese Bannermen wedded Manchus and there was no law against this.

The "Dolo efu" rank was given to husbands of Qing princesses. Geng Zhongming, a Han Chinese bannerman, was awarded the title of Prince Jingnan, and his son Geng Jingmao managed to have both his sons Geng Jingzhong and Geng Zhaozhong become court attendants under the Shunzhi Emperor and married Aisin-Gioro women, with Prince Abatai's granddaughter marrying Geng Zhaozhong and Haoge's (a son of Hong Taiji) daughter marrying Geng Jingzhong. A daughter of the Manchu Aisin-Gioro Prince Yolo was wedded to Geng Juzhong, who was another son of Geng Jingmao. Aisin-Gioro women were also offered to Mongols who defected to the Manchus. The Manchu Prince Regent Dorgon gave a Manchu woman as a wife to the Han Chinese official Feng Quan, who had defected from the Ming to the Qing. Feng Quan willingly adopted the Manchu queue hairstyle before it was enforced on the Han Chinese population and he also learned the Manchu language.

Building a mixed military

When Li Yongfang surrendered, he was given much higher status than under the Ming, and even allowed to keep his troops as retainers. Kong Youde, Shang Kexi and Geng Zhongming were also allowed to keep their personal armies. The warlord Shen Zhixiang, who had unlawfully taken over command of his deceased uncle Shen Shikui's troops as his private army, was unable to attain recognition from the Ming court. He then proceeded to lead his forces to switch allegiance to the Qing, and they became critical assets to the Qing.

There were too few ethnic Manchus to rule China, but they absorbed defeated Mongols, and, more importantly, added Han Chinese to the Eight Banners. The Manchus had to create an entire "Jiu Han jun" (Old Han Army) due to the very large number of Han Chinese soldiers absorbed into the Eight Banners by both capture and defection. The Qing showed that the Manchus valued military skills in propaganda targeted towards the Ming military to get them to defect to the Qing, since the Ming civilian political system discriminated against the military. From 1618 to 1631 Manchus received Han Chinese defectors and their descendants became Han Bannermen and those killed in battle were commemorated as martyrs in biographies.

Hong Taiji recognized that Ming defectors were needed in order to defeat the Ming, explaining to other Manchus why he needed to treat the Ming defector general Hong Chengchou leniently. Hong Taiji understood that the Ming would not be easily defeated unless Han Chinese troops wielding musket and cannon were included in the army. Indeed, among the Banners, gunpowder weapons like muskets and artillery were specifically used by the Han Chinese Banners. The Manchus established an artillery corps made out of Han Chinese soldiers in 1641. The use of artillery by Han Bannermen may have led to them being known as "heavy" soldiers (ujen cooha). The " red coat cannon" were part of the Han army (Liaodong Han Chinese) serving the Qing.

Ming officers who defected to the Qing were allowed to retain their previous military rank. The Qing received the defection of Shen Zhixiang in 1638. Among the other Han Chinese officers who defected to the Qing were Ma Guangyuan, Wu Rujie, Zu Dashou, Quan Jie, Geng Zhongming, Zu Zehong, Zu Zepu, Zu Zerun, Deng Changchun, Wang Shixian, Hong Chengchou, Shang Kexi, Liu Wuyuan, Zu Kefa, Zhang Cunren, Meng Qiaofang, Kong Youde, Sun Dingliao. Aristocratic and military ranks, silver, horses and official positions were given to Han Chinese defectors like Zhang Cunren, Sun Dingliao, Liu Wu, Liu Liangchen, Zu Zehong, Zu Zepu, Zu Kufa and Zu Zerun. Han Chinese defectors were primarily responsible for military strategy after 1631.

So many Han defected to the Qing and swelled up the ranks of the Eight Banners that ethnic Manchus became a minority within the Banners, making up only 16% in 1648, with Han Chinese Bannermen dominating at 75% and Mongol Bannermen making up the rest. It was this multi-ethnic force in which Manchus were only a minority, which unified China for the Qing. The Qing takeover was done by the multi-ethnic Han Chinese Banners, Mongol Banners, and Manchu Banners which made up the Qing military. In 1644, Ming China was invaded by an army that had only a fraction of Manchus, being multi-ethnic, with Han Chinese Banners, Mongol Banners, and Manchu Banners. The political barrier was between the commoners made out of non-bannermen Han Chinese and the "conquest elite", made out of Han Chinese bannermen, nobles, and Mongols and Manchu. It was not ethnicity which was the factor. Han Chinese (Nikan) bannermen used banners of black color and Nurhaci was guarded by Han Chinese soldiers. Other banners became a minority compared to the Han Chinese (Nikan) Black Banner detachments during Nurhaci's reign.

Lead-up to the Great Wall

Second Joseon campaign (1636–1637)

The Later Jin had forced Joseon to open markets near the borders because its conflicts with Ming had brought economic hardship and starvation to Jin subjects. Joseon was also forced to transfer suzerainty of the Warka tribe to Jin. Furthermore, a tribute of 100 horses, 100 tiger and leopard skins, 400 bolts of cotton, and 15,000 pieces of cloth was to be extracted and gifted to the Jin Khan. King Injo's brother was sent to deliver this tribute. However, in later letters to the Joseon king, Hong Taiji would complain that the Koreans did not behave as if they had lost, and were not abiding by the terms of the agreement. Joseon merchants and markets continued to trade with Ming and actively aided Ming subjects by providing them with grain and rations. Hong Taiji rebuked them, saying that the food of Joseon should only be fed to Joseon subjects.

Prior to the invasion, Hong Taiji sent princes Abatai, Jirgalang, and Ajige to secure the coastal approaches to Korea, so that Ming could not send reinforcements. On 9 December 1636, Hong Taiji led Manchu, Mongol, and Han Chinese Banners against Joseon. Chinese support was particularly evident in the army's artillery and naval contingents. The defected Ming mutineer Kong Youde, ennobled as the Qing's Prince Gongshun, joined the attacks on Ganghwa and Ka ("Pidao"). The defectors Geng Zhongming and Shang Kexi also played prominent roles in the Korean invasion. Koreans continue to maintain anti-Manchu hatred and sentiments after the 1636 Qing invasion of Korea.

After the Second Manchu invasion of Korea, Joseon Korea was forced to give several of their royal princesses as concubines to the Qing Manchu regent Prince Dorgon. In 1650 Dorgon married the Korean Princess Uisun. The princess' name in Korean was Uisun and she was Prince Yi Kaeyoon's (Kumrimgoon) daughter. Dorgon married two Korean princesses at Lianshan.

Campaigns against the Amur tribes

The Qing defeated the Evenk- Daur federation led by Evenki chief Bombogor and beheaded Bombogor in 1640, with Qing armies massacring and deporting Evenkis and absorbing the survivors into the Banners. The Nanais at first fought against Nurhaci and the Manchus, led by their own Nanai Hurka chief Sosoku before surrendering to Hong Taiji in 1631. Mandatory shaving of the front of all male heads was imposed on Amur peoples conquered by the Qing like the Nanais. The Amur peoples already wore the queue on the back of their heads but did not shave the front until the Qing subjected them and ordered them to shave. The Qing married off Manchu princesses to Amur chiefs who submitted to their rule. The Daurs and Tungusic peoples of the Amur region (Evenks, Nanais) and other ethnicities of this region were absorbed into the Qing Eight Banners system.

Liaoxi campaign (1638–1642)

In 1638, Qing armies raided deep into the interior of China as far as Jinan in Shandong province and immediately retreated back across the Great Wall. The Ming emperor insisted on concentrating all efforts at fighting the rebel armies instead, likening the Qing to be a mere "skin rash" while the rebels were a "visceral disease". In 1641, Jinzhou was besieged by a force of over 30 cannons of Han Chinese banner artillery under Manchu prince Jirgalang, with supporting Korean artillery under the command of Yu Im. The Koreans, however, were incapacitated by outbreaks of disease. The fortress city of Songshan fell next after a major battle, due to the defection and betrayal of Ming commander Xia Chengde. The emperor responded by ordering the Ningyuan garrison commander Wu Sangui to go on the offense, but he was quickly repelled. Manchu prince Abatai then led another raid into the interior of China, reaching the northern Jiangsu province and looting 12,000 gold tael
