Emperor Quang Trung (; , 1753 â 16 September 1792) or Nguyá» n Huá» (), also known as Nguyá» n Quang Bình (), or Há» Thám (chữ Hán: è¡𦹳) was the second emperor of the Tây Sán dynasty, reigning from 1788 until 1792. He was also one of the most successful military commanders in Vietnam's history. Nguyá» n Huá» and his brothers, Nguyá» n Nhạc and Nguyá» n Lữ, together known as the Tây Sán brothers, were the leaders of the Tây Sán rebellion. As rebels, they conquered Vietnam, overthrowing the imperial Later Lê dynasty and the two rival feudal houses of the Nguyá» n in the south and the Trá»Ânh in the north.
After several years of constant military campaigning and rule, Nguyá» n Huá» died at the age of 40. Prior to his death, he had made plans to continue his march southwards in order to destroy the army of Nguyá» n ÃÂnh, a surviving heir of the Nguyá» n lords.
Nguyá» n Huá»Â's death marked the beginning of the downfall of the Tây Sán dynasty. His successors were unable to implement the plans he had made for ruling Vietnam, leaving the empire weak and vulnerable. The Tây Sán dynasty was overthrown by its enemy, Nguyá» n ÃÂnh, who established the imperial Nguyá» n dynasty in 1802.
According to multiple sources, Nguyá» n Huá»Â's ancestors were peasants who lived in Nghá» An. They left Nghá» An and moved to southern Vietnam after an attack by the Nguyá» n lords against the Trá»Ânh lords in Nghá» An. His ancestors' surname was Há» (), but Huá»Â's great-grandfather Há» Phi Long, who was a servant of the Dinh family of Bằng Chân hamlet, Tuy Viá» n district (or An Nhán), Quy Nhán province, married a woman from the Dinh family and had a son named Há» Phi Tiá» n, Huá»Â's grandfather. Há» Phi Tiá» n did not continue farming as his father, but instead traded in betel. Through his work he met and married Nguyá» n Thá» ÃÂá»Âng (鮿°Âä»Â), the only daughter of a rich betel tradesman residing in Tây Sán village. One of their children was Huá»Â's father Há» Phi Phúc (è¡ä¸Âç¦Â, also known as Nguyá» n Phi Phúc). Some sources say that in taking on the surname Nguyá» n, the family followed the surname of Huá»Â's mother; other sources say that it followed the surname of Nguyá» n lords of southern Vietnam.
Nguyá» n Huá» was born in 1753 in Tây Sán village, Quy Nhán Province (now Bình ÃÂá»Ânh Province). His father had eight children; later, three of them took part in the Tây Sán Rebellion. According to ÃÂại Nam chÃÂnh biên liá»Ât truyá»Ân, the Tây Sán brothers, listed from eldest to youngest, were Nguyá» n Nhạc, Nguyá» n Lữ, Nguyá» n Huá»Â. However, other source reported that Nguyá» n Lữ was the youngest one. His birth name was Há» Thám, he also had a nickname ÃÂức ông Tám (Sir Eighth the virtue).
ÃÂại Nam chÃÂnh biên liá»Ât truyá»Ân described Nguyá» n Huá» as "a cunning man, good at fighting; he has bright penetrating eyes, and always speak in a stentorian voice, everyone fears him." His father, Nguyá» n Phi Phúc, made the three brothers dedicate themselves to their studies early in life. Their martial arts master was Trðáng VÃÂn Hiến, a retainer (môn khách) and friend of Trðáng VÃÂn Hạnh (å¼µæÂÂ幸), who in turn was the teacher of Nguyá» n Phúc Luân, the father of Nguyá» n ÃÂnh. After Trðáng VÃÂn Hạnh killed by the powerful chancellor Trðáng Phúc Loan, Trðáng VÃÂn Hiến fled to Bình ÃÂá»Ânh. He was first man to discover the talents of the Tây Sán brothers and to advise them to do great deeds.
Later, Trðáng VÃÂn Hiến encouraged Nguyá» n Nhạc to revolt against Nguyá» n lords: "The prophecy says: 'Revolt in the West, success in the North'. You are born in Tây Sán District, you must do your best." Nguyá» n Nhạc then gathered people to help him in his rebellion, saying to "overthrow the Trá»Ânh lords, revive the Lê dynasty".
Seeking to overthrow the corrupted Trðáng Phúc Loan and to help the prince Nguyá» n Phúc Dðáng, the eldest of the Tây Sán Brothers, Nguyá» n Nhạc, gathered an army and revolted in 1771. He was aided by his brothers Nguyá» n Huá» and Nguyá» n Lữ. In the early days of the rebellion, Huá» was the most helpful of Nhạc's generals both in finance and in training the army; with the encouragement of Trðáng VÃÂn Hiến and his own talent, Huá» rapidly increased his own popularity and that of the Tây Sán Rebellion.
Due to its popularity, the Tây Sán army grew strong and attracted many talented generals, including Nguyá» n Thung, Bùi Thá» Xuân, Võ VÃÂn Dà ©ng, Võ ÃÂình Tú, Trần Quang Diá»Âu, Trðáng Mỹ Ngá»Âc, and Võ Xuân Hoài. The rebels became famous for their policy: "fair, no corruption, only looting the rich, and help the poor" (công bằng, không tham nhà ©ng, vàchá» cðá»Âp cá»§a cá»§a ngðá»Âi giàu, giúp ngðá»Âi nghèo).
After 200 years of holding power in southern Vietnam, the government of the Nguyá» n Lords had become progressively weaker, due to its poor leadership and internal conflicts. Following the death of Lord Nguyá» n Phúc Khoát, the powerful official Trðáng Phúc Loan began to arrogate to himself control over the Nguyá» n government. For the purpose of resisting against the excessive power of Trðáng Phúc Loan and coming to the assistance of Prince Nguyá» n Phúc Dðáng, the Tây Sán Brothers gathered an army and revolted against the government of the Nguyá» n Lords. The rebel army of the Tây Sán quickly occupied the central part of Nguyá» n's territory covering from Quy Nhán to Bình ThuáºÂn, thereby weakening the authority of the Nguyá» n government.
In 1774, the government of the Nguyá» n lords sent a large army led by general Tá»Âng Phðá»Âc Hiá»Âp against the Tây Sán rebels. From Gia ÃÂá»Ânh, the troops marched to northern central Vietnam, and after several battles they recaptured Bình ThuáºÂn, Diên Khánh, and Bình Khang (modern Ninh Hòa). The rebel army of the Tây Sán now only held the land from Phú Yên to Quảng Ngãi.
Also in 1774, the ruler of northern Vietnam, Trá»Ânh Sâm, sent a massive army of 30,000 soldiers led by general Hoàng Ngà © Phúc southwards with the same purpose as that of the Tây Sán rebel army, namely to help the Nguyá» n Lords fight Trðáng Phúc Loan. The northern troops were unobstructed in their march to Phú Xuân, the governmental capital of the Nguyá» n Lords. The government of the Nguyá» n Lords feared the beginning of an unmanageable war on two fronts. Officials of the government arrested Trðáng Phúc Loan and gave him up to the troops of the Trá»Ânh Lords. The Trá»Ânh lords, however, continued attacking Phú Xuân under the pretext of helping the Nguyá» n Lords suppress the Tây Sán rebellion. The Nguyá» n Lord Nguyá» n Phúc Thuần and his officials initially attempted to resist the attack, but ended up fleeing to Quảng Nam.
Seizing the opportunity, Nguyá» n Nhạc led an army (with naval support from Chinese pirates) against Nguyá» n lords. Once again, the Nguyá» n Lord Nguyá» n Phúc Thuần fled, this time by sea to Gia Dinh, accompanied by Nguyá» n Phúc ÃÂnh, and leaving behind his nephew Nguyá» n Phúc Dðáng. Early in 1775, the army of the Trá»Ânh Lords marched on Quảng Nam at the same time as the Tây Sán troops reached Quảng Nam. Tây Sán troops searched for and then captured Nguyá» n Phúc Dðáng. The army of the Trá»Ânh Lords crossed the Hải Vân Pass, engaged the Tây Sán troops, and defeated them.
At the same time, the general of the Nguyá» n lords Tá»Âng Phðá»Âc Hiá»Âp (å®Âç¦Âæ´½) led his troops against Phú Yên, forcing the Tây Sán army to withdraw.
Fearing a war on two fronts, Nguyá» n Nhạc sent Hoàng Ngà © Phúc a proposal that if the Trá»Ânh lords recognized the Tây Sán Rebel Army, the Tây Sán would help the Trá»Ânh lords fight against the Nguyá» n Lords. The proposal was accepted, and Nguyá» n Nhạc was made an official of the Trá»Ânh lords. Nhac also made peace with the Nguyá» n lords, causing Tá»Âng Phðá»Âc Hiá»Âp to take off the pressure, and deluded Prince Nguyá» n Phúc Dðáng. His diplomacy provisionally made Tây Sán's enemies inactive and bought him valuable time to shore up his army.
Recognizing that the temporary ceasefire was unlikely to endure, Nguyá» n Nhạc retrained the rebel army, recruited new soldiers, fortified ÃÂá» Bàn fortress, and built new bases, preparing for an attack.
Tá»Âng Phðá»Âc Hiá»Âp, who had been deceived by Nguyá» n Nhạc peaceful overtures, did not pay much attention to Nhạc's activities. He did not prepare for either defending or attacking. Nhạc made use of Hiá»Âp's inactivity, and sent troops led by his brother Nguyá» n Huá» against him. The Tây Sán troops swiftly defeated the unprepared troops of the Nguyá» n Lords and inflicted heavy losses upon them. Tá»Âng Phðá»Âc Hiá»Âp and his troops fled to Van Phong. It was the first great victory achieved by Huá»Â. Nhạc sent news of the victory to Hoàng Ngà © Phúc. On Phúc's request, the Trinh rewarded Nhạc with a new office.
Because the troops of the Trá»Ânh Lords lacked familiarity with the southern country, Hoàng Ngà © Phúc withdrew the troops to the north. En route, he died of natural causes. Phúc's death marked the end of the Trá»Ânh Lords' interventions in the south. While the army of the Trá»Ânh Lords withdrew to ThuáºÂn Hóa, Tây Sán moved quickly in sending its troops to take over the abandoned territory and to suppress elements loyal to the Nguyá» n Lords.
Having gained a lot of new rich land without facing much opposition, the Tây Sán army grew stronger. Nhạc had a desire to expand Tây Sán's authority. He sent a large army led by his youngest brother Nguyá» n Lữ to launch a sudden attack against Gia ÃÂá»Ânh (now called Ho Chi Minh City) by sea. Lữ's raid was successful: he occupied Saigon and forced the Nguyá» n Lord and his followers to flee to Biên Hòa. His success was short-lived, however, when an army loyal to the Nguyá» n Lords and led by a man named ÃÂá» Thanh Nhán rose against him in ÃÂông Sán. The loyalist army attacked and forced Tây Sán's troops to withdraw from Saigon. Before withdrawing, Lữ seized the local foodstores and took them back to Quy Nhán.
In 1776, Nguyá» n Nhạc proclaimed himself King of Tây Sán (), choosing ÃÂá» Bàn as his capital, renamed it Thành Hoàng ÃÂế (Imperial City). He gave Huá» the title Phụ ChÃÂnh (Vice National Administrator).
In 1777, Nguyá» n Huá» and Nguyá» n Lữ led an army marched further south. They captured Saigon, destroyed Nguyá» n lords' army successfully. Most members of Nguyá» n royal family killed or executed in this campaign, except Nguyá» n ÃÂnh. ÃÂnh fled to Rạch Giá then to HàTiên. Finally, ÃÂnh fled to Pulo Panjang together with a French priest Pigneau de Behaine. After the battle, Huá» and Lữ returned to Quy Nhán, only a small army was left in Gia ÃÂá»Ânh. Nguyá» n ÃÂnh returned and occupied Gia ÃÂá»Ânh in the next year. With the help of de Behaine, ÃÂnh made Western weapons, recruited Western adventurers, proclaiming the restoration of Nguyá» n lords' regime. In 1782, a Tây Sán army under Nguyá» n Nhạc and Nguyá» n Huá» reoccupied Gia ÃÂá»Ânh. Nguyá» n ÃÂnh had to flee to Phú Quá»Âc.
In Phú Quá»Âc, Nguyá» n supporters suffered from Tây Sán's frequent attacks and lacked food and drinking water. Châu VÃÂn Tiếp was sent to Bangkok to request for aid. In 1783, Nguyá» n ÃÂnh and his supporters retreated to Siam with Siamese army. In Bangkok, ÃÂnh was warmly welcomed by king Rama I. Rama I promised that Siamese would help Nguyá» n ÃÂnh to retake his lost kingdom.
The Siamese army moved towards southern Vietnam in 1784. A fleet with twenty thousand men under Chao Fa Krom Luang Thepharirak was dispatched to attack and recapture Saigon for Nguyá» n ÃÂnh. ÃÂnh and his supporters were also allowed to accompany with the Siamese army. Phraya Wichinarong led Siamese infantry marched to Cambodia, and manoeuvred the Cambodian army. The Cambodian regent, Chaophraya Aphaiphubet (Baen), recruited five thousand soldiers to accompany with Siamese troops.
Siamese troops defeated Tây Sán army and captured several places including Rạch Giá, Trấn Giang (Cần Thá), Ba Thắc (Srok Pra-sak, Sóc TrÃÂng), TràÃÂn, Sa ÃÂéc, Mân ThÃÂt (or Mang thÃÂt, Man Thiết), and controlled HàTiên, An Giang and Vénh Long. However, they met a stubborn resistance from Tây Sán army, and could not capture any important places. Unable to repulse the enemy, general Trðáng VÃÂn ÃÂa sent ÃÂặng VÃÂn Trấn to Quy Nhán for help.
The Tây Sán reinforcements led by Nguyá» n Huá» reached Gia ÃÂá»Ânh in 1785. Huá» sent an envoy to Siamese army under a banner of truce. Huá» showed fear deliberately, requested Siamese not to support Nguyá» n ÃÂnh. It proved that it was an excellent stratagem; Thepharirak was taken in. On the morning of 20 January 1785, Siamese fleet was surrounded in Rạch Gầm River and Xoài Mút River (near Mỹ Tho River, in present-day Tiá»Ân Giang Province). The battle ended with a near annihilation of the Siamese fleet, all the ships of the Siamese navy were destroyed. Thepharirak and Nguyá» n ÃÂnh fled back to Bangkok.
Northern Vietnam fell into chaos in 1786. An army under Nguyá» n Huá»Â, Và © VÃÂn NháºÂm and Nguyá» n Hữu Chá»Ânh marched north to attack Phú Xuân. The governor of Phú Xuân, Phạm Ngô Cầu, was a venal and superstitious coward, he was at odds with his assistant, Hoàng ÃÂình Thá»Â. An itinerant Taoist priest came to Phú Xuân, and said to Cầu that he should set up an altar to pray for himself. Cầu was persuaded; he built an altar, ordered his soldiers to serve him day and night, making his soldiers very tired. Take this opportunity, Huá» launched a raid on Trá»Ânh army. Hoàng ÃÂình Thá» was killed in action. Phạm Ngô Cầu surrendered to Tây Sán army.
After the capture of Phú Xuân, Chá»Ânh encouraged Huá» to overthrow Trá»Ânh lord. Huá» took his advice, marched further north without Nguyá» n Nhạc's order. Tây Sán army easily defeated several Trá»Ânh troops. When they reached ThÃÂng Long (modern Hanoi), Trá»Ânh Khải came to the battlefield to fight against Tây Sán army. Tây Sán army attacked war elephants with arquebuses, finally, they captured ThÃÂng Long (modern Hanoi) successfully. Huá» met Lê Hiá»Ân Tông in the next day; he said he marched north to overthrow of Trá»Ânh lords, and did not have any other intentions. Huá» was warmly welcomed by Lê Hiá»Ân Tông, and received the position Nguyên-soái (å Â帥 "supreme commander") noble title Uy-quá»Âc-công (å¨ÂÃ¥ÂÂå ¬). He also married Lê Ngá»Âc Hân, a daughter of the Lê Emperor. The old emperor died several days later. Lê Chiêu Thá»Âng was enthroned by Huá»Â. Although he had not been proclaimed as an Emperor at all, Nguyá» n Huá» was respected by citizens of ThÃÂng Long as the way an Emperor would be treated.
Nguyá» n Nhạc did not want to take northern Vietnam; he sent an envoy to Phú Xuân to prevent Huá» from marching north, but Huá» had left. Then he got the message that Huá» had captured ThÃÂng Long, and realized that Huá» was hard to be controlled. Nhạc led 2500 men and marched north to meet with Huá» and the Lê emperor. In ThÃÂng Long, Nhạc promised that he would not take any territory of Lê emperor. Then Nhạc retreated from ThÃÂng Long together with Huá»Â. Và © VÃÂn NháºÂm disliked Nguyá» n Hữu Chá»Ânh, and persuaded Huá» to leave Chá»Ânh in northern Vietnam. Huá» led his army back to Phú Xuân secretly. Chá»Ânh abandoned all his property, and came to Nghá» An to join Tây Sán army. Nguyá» n Nhạc did not have the heart to abandon him again; Chá»Ânh was left in Nghá» An together with a Tây Sán general, Nguyá» n VÃÂn Duá»Â.
In the same year, Nguyá» n Nhạc proclaimed himself as Trung ðáng Hoàng ÃÂế (ä¸Â央çÂÂ帠"the Central Emperor"). Huá» received the title Bắc Bình Vðáng (Ã¥ÂÂå¹³ç "King of Northern Conquering"), the area north to Hải Vân was given as his fief. But not long after, he came into conflict with Nguyá» n Nhạc. Nhạc attacked on Huá» at first, a civil war broke out.
But the military might of Huá» was stronger than Nhạc. Huá» besieged Quy Nhán for several months. The main forces of Gia ÃÂá»Ânh was called back to support Nhạc, but was defeated in Phú Yên, its commander ÃÂặng VÃÂn Chân surrendered to Huá»Â. Nhạc climbed onto the city wall, and shouted to Huá»Â: "How can you use the pot of skin to cook meat like that?" It is an old custom, if hunters seized a prey in the jungle without a pot, they would flay it and use its skin to cook meat. Using this metaphor, Nhạc indicated that brothers should not fight with each other. Huá» was moved to tears, and decided to retreat. Taking the advice of Trần VÃÂn Ká»·, Huá» decided to reach a peace agreement Nhạc. The two brothers chose Bến Bản as a boundary; the area north to Quảng Ngãi was Huá»Â's area; the area south to ThÃÂng Bình and ÃÂiá»Ân Bàn belonged to Nhạc. From then on, they ceased fire with each other.
During Nguyá» n Huá»Â's absence, northern Vietnam fell into chaos again. The regime of Trá»Ânh lord restored. Lê Chiêu Thá»Âng could not control the situation, he asked for assistance from Nguyá» n Hữu Chá»Ânh. Though Trá»Ânh Bá»Âng was banished from ThÃÂng Long, Chá»Ânh became the new regent just like Trá»Ânh lords before. After learning about actions of Chá»Ânh, an army under Và © VÃÂn NháºÂm was sent by Huá» to attack ThÃÂng Long. Chá»Ânh was swiftly defeated and fled together with Lê Chiêu Thá»Âng.
Chá»Ânh was found and executed, but NháºÂm could not find Lê Chiêu Thá»Âng. In order to gain popularity among Northern Vietnamese, NháºÂm install Lê Duy CáºÂn as giám quá»Âc ("Prince Regent"). Two generals, Ngô VÃÂn Sá» and Phan VÃÂn Lân, reported it to Huá»Â. Huá» led an army marched north, and launched a night raid. Sá» and Lân opened the gate to let them in. Huá» captured NháºÂm and had him executed.
Huá» led his army back to Phú Xuân. Lê Duy CáºÂn remained in his position; Ngô VÃÂn Sá»Â, Phan VÃÂn Lân, Nguyá» n VÃÂn Tuyết, Nguyá» n VÃÂn Dụng, Trần ThuáºÂn Ngôn and Ngô Thì NháºÂm, were left in ThÃÂng Long to watch CáºÂn.
Lê Chiêu Thá»Âng never abandoned his attempt to regain the throne. He hid in Bảo Lá»Âc Mountain; in there, he had a plan to fight against Tây Sán. His mother, Empress Dowager Mẫn, fled to Longzhou, called for help from Qing China in order to restore Lê dynasty. The Qianlong Emperor of Qing China decided to restore Lê Chiêu Thá»Âng to the throne, though under Qing protection.
Two Chinese armies invaded Vietnam in October of the lunar year MáºÂu Thân (November, 1788): Liangguang army under Sun Shiyi and Xu Shiheng, as the main force, marched across the South Suppressing Pass (present day Friendship Pass); Yungui army under Wu Dajing, marched across the Horse Pass (Maguan); the two armies aimed to attack ThÃÂng Long directly.
When Liangguang army reached Lạng Sán, Sun announced that there was a very large number of Qing army, in order to threaten Tây Sán soldiers. Chinese marched south swiftly. Realizing Tây Sán army could not stop Chinese army from marching to ThÃÂng Long, Ngô VÃÂn Sá» accepted Ngô Thì NháºÂm's idea, abandoned ThÃÂng Long and retreated to Tam ÃÂiá»Âp orderly. In Tam ÃÂiá»Âp, Ngô VÃÂn Sá» sent Nguyá» n VÃÂn Tuyết to Phú Xuân to ask for aid.
Nguyá» n Huá» knew the situation on Lunar 24 November (21 December 1788), cursing the invaders. Huá» declared that Lê Chiêu Thá»Âng was a national traitor and not qualified for the throne. In the next day, Nguyá» n Huá» erected an altar on a hill south of Phú Xuân and proclaimed himself Emperor Quang Trung, in effect abolishing the Lê dynasty. After the coronation, he marched north with 60,000 soldiers. He recruited volunteers in Nghá» An Province, now the number of his soldiers reached 100,000. In Thá» Hạc (Thanh Hóa), he made an invigorating speech before his soldiers. Soldiers replied a great shout of approval. They were encouraged, and marched quickly.
Huá» arrived in Tam ÃÂiá»Âp on Lunar 20 December (15 January 1789). In there, Huá» gathered together the whole forces, and divided them into five branches: main force led by Huá»Â, marched north to attack ThÃÂng Long directly; a navy led by Nguyá» n VÃÂn Tuyết (Commander Tuyết), sailed from to attack Lê supporters in Hải Dðáng; another navy led by Nguyá» n VÃÂn Lá»Âc (Commander Lá»Âc), sailed from Lục ÃÂầu River to attack Phðợng Nhãn and Lạng Giang; a cavalry (including war elephants) led by ÃÂặng Tiến ÃÂông, marched to attack Cen Yidong in ÃÂá»Âng ÃÂa; another cavalry (including war elephants) led by Nguyá» n TÃÂng Long (Commander Long) marched past to attack Xu Shiheng in (a place near Thanh Trì).
Meanwhile, Chinese soldiers were preparing to celebrate the Chinese New Year festival, and planned to march further south to capture Phú Xuân on 6 January of the next lunar year (31 January 1789). As Vietnamese New Year (Tết) was generally celebrated on the same day, Chinese generals assumed that Tây Sán army would not attack in these days. However, subsequent events proved that they were wrong.
Nguyá» n Huá» made a surprise and fast attack against Chinese forces during the New Year holiday. They reached ThÃÂng Long in the night of 3 January of the next lunar year (28 January 1789). In the fierce 4-day battle, most of Chinese soldiers were unprepared, they were disastrously defeated by the Tây Sán army in Ngá»Âc Há»Âi and ÃÂá»Âng ÃÂa (part of modern Hanoi). Qing generals Xu Shiheng, Shang Weisheng, Zhang Chaolong and Cen Yidong were killed in action. Many Chinese soldiers and porters were killed in action, or drowned while crossing the Red River. According to Draft History of Qing, over half number of Chinese soldiers died in the battle. Sun Shiyi, the commander-in-chief of Chinese army, abandoned his army, fled for his life back to China with several soldiers. Lê Chiêu Tông also fled to China. Huá» marched into ThÃÂng Long, his clothes was blackened by gunpowder. Tây Sán army marched further north after the battle; they reached Lạng Sán, and threatened to march across the border to arrest Lê Chiêu Thá»Âng.
After Nguyá» n Huá» defeated the Later Lê dynasty, the last Lê emperor Lê Chiêu Thá»Âng and high ranking Lê loyalists fled Vietnam for asylum in Qing China and went to Beijing. Lê Chiêu Thá»Âng was appointed a Chinese mandarin of the fourth rank in the Han Yellow Bordered Banner, while lower ranking loyalists were sent to cultivate government land and join the Green Standard Army in Sichuan and Zhejiang. They adopted Qing clothing and adopt the queue hairstyle, effectively becoming naturalized subjects of the Qing dynasty affording them protection against Vietnamese demands for extradition. Some Lê loyalists were also sent to Central Asia in Urumqi. Modern descendants of the Lê monarch can be traced to southern Vietnam and Urumqi, Xinjiang.
The irate Qianlong Emperor of the Qing replaced Sun Shiyi with Fuk'anggan. Fuk'anggan did not want a conflict with NguyỠn HuỠand he sent a letter to HuỠin which he expressed that a necessary prerequisite for a cease-fire was an apology of HuỠto the emperor. NguyỠn HuỠsought to restore the tributary relationship in order to deter a joint Qing-Siam pincer attack and prevent further Chinese attempts to restore the Lê dynasty. NguyỠn HuỠsent a ritually submissive request to the Qianlong Emperor under the name of NguyỠn Quang Bình (also referred to as Ruan Guangping).
In 1789, the Qianlong Emperor agreed to re-establish the tributary relationship and enfeoff Nguyá» n as the king of Annam on the condition that Nguyá» n personally lead a special delegation to Beijing to celebrate the Qianlong Emperor's 80th birthday. For the Qianlong Emperor, the motivation for accepting the arrangement was to retain the Qing's supremacy and stabilize their southern border. Chinese and Vietnamese sources agreed that Nguyá» n sent an imposter with a delegation to Beijing, where they were received with lavish imperial favors. The Qianlong Emperor approved the proposal and bestowed Nguyá» n with the title An Nam quá»Âc vðáng ("King of Annam"). The title indicated that Huá» was recognized as the legal ruler of Vietnam and Lê Chiêu Thá»Âng was no longer supported.
Once in power, Emperor Quang Trung first began instituting massive and unprecedented national reforms in Vietnam.
Though Quang Trung entitled as "king of Annam" by Qing China, he always regarded himself as emperor of ÃÂại Viá»Ât. He crowned Lê Ngá»Âc Hân empress, and granted her the noble title Bắc Cung hoàng háºÂu (Ã¥ÂÂå®®çÂÂå "empress of Northern Palace"); Nguyá» n Quang Toản was designated as Crown Prince.
Taking the advice of Nguyá» n Thiếp, Quang Trung decided to relocate the imperial capital in Nghá» An Province. He ordered Trần Quang Diá»Âu to build a new citadel at the foot of Kỳ Lân Hill (modern Quyết Hill in Vinh). The new citadel was named Phðợng Hoàng Trung ÃÂô (é³³å°ä¸Âé½).
ThÃÂng Long was renamed Bắc Thành (Ã¥ÂÂÃ¥ÂÂ). Sán Nam (å±±åÂÂ) split into two trấn ("town"): Sán Nam Thðợng (å±±åÂÂ丠"Upper Sán Nam") and Sán Nam Hạ (å±±åÂÂ丠"Lower Sán Nam"). Each trấn had two high officials: Trấn-thá»§ (é®宠"viceroy") and Hiá»Âp-trấn (Ã¥ÂÂé® "deputy viceroy"). Each huyá»Ân ("district") had two officials: phân-tri (Ã¥ÂÂçÂÂ¥), the civil official, took charge of judicial litigation; phân-suất (Ã¥ÂÂçÂÂ), the military official, took charge of army provisions.
The official system of Tây Sán dynasty was not mentioned in official records, but we could find several names of official positions in history records, such as tam công (ä¸Âå ¬), tam thiếu (ä¸Âå°Â), ÃÂại-chá»§ng-tá» (大å¢宰), ÃÂại-tð-ÃÂá» (大å¸å¾Â), ÃÂại-tð-khấu (大å¸å¯Â), ÃÂại-tð-mã (大å¸馬), ÃÂại-tð-không (大å¸空), ÃÂại-tð-cá»Âi (大叿ÂÂ), ÃÂại-tð-lá» (大å¸é¸), Thái-úy (太å°Â), ÃÂại-tá»Âng-quản (大總管), ÃÂại-ÃÂá»Âng-lý (大è£çÂÂ), ÃÂại-ÃÂô-ÃÂá»Âc (大é½ç£), ÃÂại-ÃÂô-há» (大é½è·), Trung-thð-sảnh (ä¸ÂæÂ¸å»³), Trung-thð-lá»Ânh (ä¸ÂæÂ¸ä»¤), ÃÂại-há»Âc-sé (大å¸士), Hiá»Âp-biá»Ân ÃÂại-há»Âc-sé (Ã¥ÂÂ辦大å¸士), Thá»Â-trung ngá»±-sá» (ä¾Âä¸Â御å²), Lục-bá» thðợng-thð (å Âé¨å°ÂæÂ¸), Tả-hữu ÃÂá»Âng-nghá» (å·¦å³åÂÂè°), Tả-hữu phụng-nghá» (å·¦å³å¥Âè°), Thá»Â-lang (ä¾ÂéÂÂ), Tð-vụ (å¸åÂÂ), Hàn-lâm (ç¿°æÂÂ), etc.
The system of military units: a ÃÂạo (éÂÂ) was composed of several cá (å¥Â), a cá was composed of several ÃÂá»Âi (éÂÂ). Quang Trung organized the army into five major wings: tiá»Ân-quân ("army of the front"), háºÂu-quân ("army of the rear"), trung-quân ("army of the center"), tả-quân ("army of the left"), hữu-quân ("army of the right"). Tây Sán army was recruited by enforced conscription. Chose one in three adult males (ÃÂinh ä¸Â), the chosen one should join the army.
Adult males of the whole country divided into three scales to pay taxes in corvée (sðu dá»Âch) and capitation (thuế thân): vá» cáºÂp cách (æÂªåÂÂæ ¼), 2 to 17 years old; tráng hạng (壯頠), 18 to 55 years old; lão hạng (èÂÂé  ); 56 to 60 years old; lão nhiêu (èÂÂé¥Â), over 61 years old. Different scales had different tax collection standards.
Farmers had to pay a fixed amount of grain as tax. Publicly owned farmland divided into three scales: the first scale paid 150 bát (é¢, a unit of weight) per ' (a unit of area); the second scale, 80 bát per mẫu; the third scale, 50 bát per mẫu. Privately owned farmland also divided into three scales: the first scale, 40 bát per mẫu; the second scale, 30 bát per mẫu; the third scale, 20 bát per mẫu.
There were also two additional taxes of farmland: tiá»Ân tháºÂp-váºÂt (é¢ä»Âç©) and tiá»Ân khoán-khá» (é¢å¸庫). Publicly owned farmland: paid 1 tiá»Ân (currency unit) per mẫu for tháºÂp-váºÂt, 50 ÃÂá»Âng per mẫu for khoán-khá»Â; privately owned farmland: paid 1 tiá»Ân per mẫu for tháºÂp-váºÂt, 30 ÃÂá»Âng per mẫu for khoán-khá»Â.
Quang Trung introduced the identity card system to govern the large population. A census was conducted during his reign. Every adult male was granted tÃÂn bài (ä¿¡çÂÂ), a wooden card on which was his name, birthplace and fingerprints. If anyone did not have the wooden card, he would be arrested and imprisoned with hard labour.
Quang Trung also replaced the traditional Chinese script with the Vietnamese chữ Nôm as the official written language of the country. Examinees were ordered to write chữ Nôm in imperial examination. Though this policy was criticized at that time, modern scholars stated that it had progressive significance.
A religious reform was carried out during his reign. Many small Buddhist monasteries were closed and merged into larger ones. Monks had to pass an examination, otherwise, they would be ordered to return to secular life. Quang Trung also adopted a policy of religious tolerance. His religious toleration won him the support of the growing Christian community and his campaign of the common people against the traditional elites won him the admiration of the peasant majority.
After the defeat of China, a Lê prince, Lê Duy Chá» (é»Âç¶Âç¥Â), fled to Tuyên Quang and Cao Bằng. There, Chá» was supported by native chieftain Nùng Phúc Tấn (Ã¥ÂÂç¦Âç¸Â) and Hoàng VÃÂn ÃÂá»Âng (é»ÂæÂÂæ¡Â). Chá» devised a plan to unite Vientiane and Muang Phuan in a revolt of Tây Sán dynasty. An army under Trần Quang Diá»Âu conquered Muang Phuan and executed their chiefs. Then, the army invaded Kingdom of Vientiane; king Nanthasen fled, Tây Sán marched west till the border of Siam. The victorious army attacked Bảo Lá»Âc, captured Lê Duy Chá»Â, Nùng Phúc Tấn, Hoàng VÃÂn ÃÂá»Âng, and had them executed. Horses, elephants and war drums were brought to Vietnam as booty of war, then handed over to Qing China as tribute, Quang Trung did it to show power to China. Quang Trung also requested for exemption from customs duties, and established a yá háng (çÂÂè¡Â, broker house in ancient China) in Nanning, they were both agreed by the Qianlong Emperor.
There was a territorial dispute near Sino-Vietnamese border. Vietnamese claimed this territory belonged to Tuyên Quang Province and , but was illegally occupied by native chiefdom of Guangxi in final years of Lê dynasty. Quang Trung wrote a letter to Fuk'anggan, required him to return this territory. Fuk'anggan rejected, and replied the border had been delimited. Quang Trung was resentful, from then on, he began to train his soldiers and build many large warships, planning to invade Liangguang. It was said that Quang Trung looked down upon the Qianlong Emperor. He said to his ministers that if given more time to train soldiers, he was not afraid to conflict with China.
Nguyá» n Huá» was resentful, trained his army, built large warships and waited for an opportunity to take revenge on China. He also provided refuge to anti-Manchu organizations such as the Tiandihui and the White Lotus. Infamous Chinese pirates, such as Chen Tien-pao (é³添ä¿Â), Mo Kuan-fu (è«è§ÂæÂ¶), Liang Wen-keng (æ¢ÂæÂÂåºÂ), Fan Wen-tsai (æ¨ÂæÂÂæÂÂ), Cheng Chi (éÂÂä¸Â) and Cheng I (éÂÂä¸Â) were granted official positions and/or noble ranks under the Tây Sán empire. With the support of Tây Sán dynasty, the number of Chinese pirates grew rapidly, they were able to block sea routes, and harassed the coastlines of China. The attack on China never materialized by the time that Quang Trung died in 1792.
In 1792, Quang Trung decided to invade China. There was evidence that he had the intention to conquer South China. Quang Trung attempted to seek a Chinese princess in marriage, and demanded that Liangguang should be ceded to Vietnam as dowry. He knew the Qianlong Emperor would not accept his unreasonable demand; he just wanted an excuse of war. But finally, the messager Võ Chiêu Viá» n (æÂ¦æÂÂé ) did not set out because Quang Trung fell ill.
Quang Trung suddenly fell ill. The official records did not mention about what disease he got. Contemporary historians stated that his death was possibly due to a stroke. Legend had it that he died actually because he was punished by spirits of dead Nguyá» n lords whose tombs he seriously insulted.
Quang Trung called Trần Quang Diá»Âu back to Phú Xuân. He set a schedule to move the capital to Phðợng Hoàng trung ÃÂô (present-day Vinh) together with high ministers. At this time, he got the information that Nguyá» n ÃÂnh had captured Bình ThuáºÂn, Bình Khang (modern Ninh Hòa) and Diên Khánh. He was depressed, and soon became critically ill. On his deathbed, Quang Trung was worried about the future of Tây Sán dynasty. He described the Crown Prince Nguyá» n Quang Toản as "a clever boy but too young", described Nguyá» n Nhạc as "an old man who is resigned to the present state of affairs". His will instructed that he be buried within a month; all ministers and generals should be united as one to assist the Crown Prince; and move the capital to Phðợng Hoàng trung ÃÂô as soon as possible. If not, one day all of them will be killed by Nguyá» n ÃÂnh.
Quang Trung was buried on the southern bank of Perfume River. He was buried secretly; Ngô Thì NháºÂm stated that Quang Trung was buried in ÃÂan Dðáng Palace (cung ÃÂiá»Ân ÃÂan Dðáng). The exact location was not clear; Nguyá» n ÃÂắc Xuân, a culture researcher, believed that it was located at Bình An Village, Huế.
Quang Trung received temple name Thái Tá» (太ç¥Â) and posthumous name Và © Hoàng ÃÂế (æÂ¦çÂÂå¸Â) from his successor, Nguyá» n Quang Toản. Getting the information, Nguyá» n Nhạc prepared to attend his funeral, however, the road was blocked by Toản. Nhạc had to return, and sent a sister to attend the funeral.
The plan to invade China was given up. Nguyá» n Quang Toản built a fake tomb in Linh ÃÂðá»Âng (èÂÂå¡Â, a place in modern Thanh Trì District) for him. Then Toản reported his death to the Qianlong Emperor: "I followed my father's will, buried him in Linh ÃÂðá»Âng instead of his birthland because he was reluctant to leave your palace, and Linh ÃÂðá»Âng was nearer to your palace." The Qianlong Emperor praised Quang Trung, gave him the posthumous name Trung Thuần (å¿ ç´ lit. "loyalty and sincerity"). He also composed a funeral oration for Quang Trung. In the oration, the Qianlong Emperor wrote: "(You have) blessed (me) and pledged loyalty (to me) in the southernmost, (so I) approved you to attend (my) imperial court; (now you) lie at rest beside the West Lake, (you are) nostalgic for (the good old days in) my palace till death." (ç¥ÂéÂÂÃ¥ÂÂ極å¹忠ç¹çÂÂ堶趨æÂ å¦¥éÂÂ西æ¹Âæ²Âä¸Âç¡å¿ÂæÂ¼æÂÂéÂÂ). The oration was engraved on a stone, and erected beside his fake tomb. A Chinese official was sent to Linh ÃÂðá»Âng to pay condolences, and granted Nguyá» n Quang Toản the title An Nam quá»Âc vðáng ("King of Annam").
However, Nguyá» n Quang Toản (now crowned the Emperor Cảnh Thá»Ânh) did not continue his father's policies. The identity card system was abolished, and the capital remained in Phú Xuân. High ministers and generals struggled for power, which led to the decline of his empire.
Tây Sán dynasty was overthrown by Nguyá» n ÃÂnh in 1802 after a ten years long war. Quang Trung's sons: Nguyá» n Quang Toản, Nguyá» n Quang Thùy, Nguyá» n Quang Duy (é®å Âç¶Â), Nguyá» n Quang Thiá»Âu (é®å Âç´¹) and Nguyá» n Quang Bàn (é®å Âç¤), were captured alive. Nguyá» n Quang Thùy committed suicide; the others were executed by having their bodies dismembered by having five elephants pull the limbs and head (äºÂ象åÂÂå±Â). The tombs of Nguyá» n Nhạc and Nguyá» n Huá» were razed to the ground, their remains were dug out and crushed into ashes. The skulls of Nguyá» n Nhạc, Nguyá» n Huá» and Huá»Â's wife, were locked up in prison in perpetuity. It was said that Nguyá» n Huá» had desecrated the tombs of Nguyá» n lords before, Nguyá» n ÃÂnh did that to "revenge for the ancestors".
Tây Sán dynasty was regarded as an illegal regime during Nguyá» n dynasty; it was mentioned as Nguỵ Tây (Ã¥ÂÂ西 "False Tây"), or Tây tặc (西賠"Bandit Tây") in Nguyá» n official records to highlight the supposed illegitimacy of the dynasty.
Nguyá» n Huá» was regarded as the national savior of Vietnam and one of the most popular figures in the country.
Nguyá» n Huá» was deified in Vietnamese culture, Bá»Âc Temple (Chùa Bá»Âc) in Hanoi was a temple to him.
Nguyá» n Huá» was depicted on the South Vietnamese 200 ÃÂá»Âng banknote.
Most cities in Vietnam, regardless of the political orientation of the government, have named major streets after him.
In his hometown, Quang Trung Museum has been built to showcase valuable historical documents and artifacts from the Tay Son dynasty.
Tây Sán hào kiá»Ât, a Vietnamese film, was based on his story.
On 6 February 2018 the Vietnam People's Navy commissioned the Quang Trung a currently in service with the 4th Regional Command.
