Fourth Era of Northern Domination
The Fourth Era of Northern Domination was a period of Vietnamese history, from 1407 to 1427, during which Đại Việt (the northern kingdom) was ruled by the Chinese Ming dynasty as the province of Giao Chỉ (). It was the result of the Ming conquest of Vietnam (1406-1407). The previous periods of Chinese rule, collectively known as the Bắc thuộc periods in Vietnam, were longer-lasting, constituting much of Vietnam's history from 111 BC to 880/907 AD. The fourth Chinese occupation of Vietnam was eventually ended with the reestablishment of Đại Việt under the  new Later Lê dynasty. History. Ming conquest of Vietnam. In mid-late 14th century, the kingdom of Đại Việt (north Vietnam) faced a series of troubles resulting in an ecological breakdown. This led to the rising of a radical intellectual and reformer, Hồ Quý Ly (c. 1336 – 1408). In 1400, Hồ Quý Ly deposed and massacred the Trần house before usurping the throne. After taking the throne, Hồ Quý Ly renamed the country from Đại Việt to Đại Ngu. In 1402, he abdicated the throne in favor of his son, Hồ Hán Thương. In October 1404, Trần Thiêm Bình arrived  at the Ming imperial court in Nanjing, claiming to be a Trần prince. He notified the court of the treacherous events that had taken place and appealed to the court for the restoration of his throne. The Yongle Emperor of the Ming Empire issued an edict reprimanding the usurper and demanding the restoration of the Trần throne, a pretext for the annexation of Đại Việt. As the party crossed the border into Lạng Sơn, Hồ's forces ambushed them and killed the Trần prince that the Ming convoy were escorting back. Upon hearing the news, Yongle reportedly said "If we  do not destroy them, what are armies for?". Yongle, who inherited some interests in the world empire, sent additional forces to punish Hồ Quý Ly. In November 1406, 215,000 Ming troops under skilled generals Zhang Fu and Mu Sheng departed from Guangxi and Yunnan respectively to launch an invasion of Đại Việt. On 19 November 1406, they captured the two capitals and other important cities in the Red River Delta. They quickly defeated Hồ Quý Ly's army and occupied the country. Hồ Quý Ly and his son were captured on 16 June 1407, and were caged and brought as  prisoners to the Yongle Emperor in Nanjing. After his initial campaign in Vietnam, Zhang Fu sent a letter urging the Chinese court to annex Đại Việt and rule it as a province of China: Furthermore, Zhang Fu wrote that 1,100 members of the Vietnamese elite requested that they be absorbed, again into the Chinese state. The Ming's ethnic Vietnamese collaborators included Mac Thuy whose grandfather was Mạc Đĩnh Chi who was a direct ancestor of Mạc Đăng Dung. The Chinese then renamed the Vietnamese land to a Han-era name Jiaozhi and incorporated the former kingdom into their empire . Revolt of Trần royals. The Chinese army turned into an occupation force. Despite support from some sectors of Vietnamese society, ongoing local resistance forced the Ming to retreat. There were several revolts among the Vietnamese people against the Ming authorities, but they all proved unsuccessful. Among the people who led rebellions were, Trần Ngỗi (revolted 1407–09), a young son of the late king Trần Nghệ Tông and Trần Quý Khoáng, a nephew. These revolts were short-lived and poorly planned but they helped lay some of the groundwork for Lê Lợi's war of independence. After the defeat of the  Trần-led revolts, between 1415 and 1424, leaders of the uprising included Buddhist monks inspired by Vietnamese nationalism emerged in Lạng Giang, Nghệ An, Hanoi, Ninh Kiều, Lạng Sơn and other prefecture capitals where Ming troops were stationed. In the meantime, anti-Chinese activists used the heroic deeds of their martyrs to support Vietnamese patriotism and keep up the struggle against their colonial masters. Lam Sơn uprising. Lê Lợi, one of Vietnam's most celebrated heroes, is credited with rescuing the country from Ming domination in 1428. Born of a wealthy landowning family, he served as a senior scholar-official  until the advent of the Ming, whom he refused to serve. The Ming dynasty crushed Lê Lợi's rebellion at first but in 1425, the Ming Emperor Zhu Zhanji expressed his opinion that it would be better to restore the Trần dynasty and return to the old tributary relationship as Ming rule in Vietnam was a net financial loss for the Ming and there were more pressing concerns on the northern border. When in 1426, Zhang Fu requested permission to resume command of Ming Jiaozhi army to deal with the worsening situation there, the emperor refused. In 1426, Zhu Zhanji  proclaimed a general amnesty and abolished all taxes in Giao Chi except for land taxes to be paid in rice, needed to supply Ming garrisons. In early November 1426, Lê Lợi's 3,000 Vietnamese rebels achieved a surprise victory over the Ming army led by Wang Tong with about 30,000 Chinese soldiers were killed or captured in Tốt Động (32 km south of Hanoi). People in the Red River Delta welcomed and supported the Lam Son army where they came. By 1427, captured northern prisoners also furnished the rebels with siege techniques, primitive tanks, flying horse carts, Muslim trebuchets (hui  hui pao 回回砲), and possibly another artillery piece that the Chinese called a "thousand-ball thunder cannon". The Xuande Emperor of the Ming dynasty decided to end the war in Northern Vietnam. After this final victory, the Vietnamese repatriated 86,640 Ming prisoners to China and confiscated all their weapons. China would not again invade its southern neighbor for 360 years. Lê Lợi formally re-established Đại Việt as the Xuande Emperor of the Ming Empire officially recognized Lê Lợi as the king of Annam. In return, Lê Lợi sent diplomatic messages to the Ming imperial court, promising Vietnam's loyalty  as a nominate tributary state of China and cooperation. The Ming imperial court accepted this arrangement, much as they accepted the vassal status of Korea under the Joseon dynasty. The case of Vietnamese monarch Lê Lợi showed that it was possible to satisfy Chinese pride while maintaining political independence. Military and administration. The Ming Chinese built up their colonial administration in Jiaozhi Province. In July 1407, Yongle changed the name of Annam to Jiaozhi – an old Han dynasty designation – and made it a province of China. The provincial government, included an administrative office, a surveillance office and a regional military  commissioner was established, with Lu Yi (d. 1409) as its military commissioner and Huang Zhong as vice-commissioner. Huang Fu was appointed as both provincial administrator and surveillance commissioner. The Ming seized the kingdom's grain reserves of 13,6 million piculs of rice. The province was further divided into fifteen prefectures, 41 subprefectures and 210 counties. By 1408, 472 military and civil offices had been established to govern over three million people and in excess of two million "man" (barbarians), and the number of offices peaked at about 1,000 in 1419. In major towns and cities throughout the occupied regions  had moats and walls added, and troops alternated between defence and farming duties to provide their own food needs. The Ming occupying army of Jiaozhi consisted 87,000 regulars, scattered in 39 citadels and towns in Northern Vietnam, but clustered in the Red River Delta area. Chinese armies had employed firearms before the fifteenth century, but they came to possess superior weapons from Annam during the Vietnamese campaigns of the early fifteenth century. They also captured one of the leading Vietnamese firearms experts, Hồ Nguyên Trừng (1374—1446), the eldest son of Hồ Quý Ly, who was charged with manufacturing their superior  muskets and explosive weapons. The Artillery Camp was thus built around these Vietnamese firearm specialists, who instructed Ming soldiers under the supervision of palace eunuchs. The first record of firearm usage in Đại Việt was in 1390 when Vietnamese soldiers used cannons and killed the Cham king Chế Bồng Nga. The Ming government enjoyed some support from the Vietnamese, at least in the capital of Thăng Long, but their efforts to assert control in the surrounding countryside were met with stiff resistance. A general popular dissatisfaction with the colonial arrangement seems clear. When the Ming entered the country, there were  5.2 million people according to Ming Shilu, however, it was seemed as exaggeration by historians. By the end of Ming rule over Đại Việt in 1427, the population had declined to 1.9 million. Sinicization. An entry in the "Ming Shilu" (traditional Chinese: 明實錄; simplified Chinese: 明实录) dated 15 August 1406 recorded an imperial order from Emperor Yongle that instructed for Vietnamese records such as maps and registers to be saved and preserved by the Chinese army:己未敕征討安南總兵官成國公朱能等曰師入安南下郡邑凡得文籍圖志皆勿毀。In addition, according to "Yueqiaoshu" (Chinese: 越嶠書, Vietnamese: Việt kiệu thư), on August 21, 1406, the Yongle Emperor issued an order to Ming soldiers  in Annam:兵入。除釋道經板經文不燬。外一切書板文字以至俚俗童蒙所習。如上大人丘乙已之類。片紙隻字悉皆燬之。其境內中國 所立碑刻則存之。但是安南所立者悉壞之。一字不存。 "Once our army enters Annam, except Buddhist and Taoist text; all books and notes, including folklore and children book, should be burnt. The stelae erected by China should be protected carefully, while those erected by Annam, should be completely annihilated. Do not spare even one character."On the 21st day of the 5th lunar month of the following year, Emperor Yongle issued another order to Ming soldiers in Annam:屢嘗諭爾凡安南所有一切書板文字。以至俚俗童蒙所習。如上大人丘乙已之類。片紙隻字及彼處自立碑刻。見者即便毀壞勿存 。今聞軍中所得文字不即令軍人焚毀。必檢視然後焚之。且軍人多不識字。若一一令其如此。必致傳遞遺失者多。爾今宜一如前敕。號令軍中但遇彼處所有一應文字即便焚毀。毋得存留。 "I have repeatedly told you all to burnt all Annamese books, including folklore and children books and the local stelae should be destroyed immediately upon  sight. Recently I heard our soldiers hesitated and read those books before burning them. Most soldiers do not know how to read, so it will be a waste of our time. Now you have to strictly obey my previous command, and burn all local books upon sight without hesitation. The Chinese colonists encouraging the Ming Confucian ideology, bureaucratic and Classical Chinese study to the local Vietnamese people, forced the Vietnamese to wear Chinese-style clothes. The Ming forbid the local customs such as tattooing, unmarried boys and girls to cut short hair, and banned women to wear short skirts, in  order to change customs in conformity with the north. Cultural incorporation was pursued with the new Jiaozhi administration advising to the Ming court: The "yi" people of Annam venerate the law of the Buddha, but do not know to worship or sacrifice the spirits. We should establish altars for sacrifice to the spirits of the wind, clouds, thunder and rain... so that the people become familiar with the way to express gratitude to the spirits through sacrifice. In 1416, a large number of Confucian school, Yin-yang schools and medical schools were established within the province. Examinations for local bureaucracy  were formalised in 1411. Chinese mourning rites and mourning leave were instituted among the official of Jiaozhi in 1419. For the first time, Đại Việt experienced the sustained influence of Neo-Confucian ideology, which not only included the traditional doctrines of filial piety but also demanded an "activist, state-oriented service" based on officials’ absolute loyalty to the dynasty and on the moral superiority of the "civilized" over the "barbarian" as the Ming viewed the Vietnamese as barbarians. Yongle brought Vietnamese students to the National Institution at the Ming capital and appointed more natives to the minor local offices in  Jiaozhi. The Ming also destroyed or brought to the north many Vietnamese vernacular writing, historical and classic texts. After regained independence, Vietnamese monarch Lê Thánh Tông issued royal edict in 1474 to forbid Vietnamese from adopting foreign languages, hairstyles and clothes like the Laotians, Chams and the Ming Chinese, abolished the Ming forced customs. The Mongol, Cham, and Ming invasions of 13th-15th centuries destroyed many Vietnamese important sites, buildings, artifacts, and archives of the Postclassical period. Economy. Ming goals in Jiaozhi also included labor control and economic exploitation. Imperial orders dispatched in early 1407 required that: When the troops overcome  Annam, enquire far and wide within the borders for knowledgeable and moral men, as well as those who have abilities which can used or skills which can be employed. Such person could, with due ceremony, all be sent to the Court. The Ming government began a harsh rule of both colonization and sinicization. In October 1407, 7700 tradesmen and artisans from Đại Việt were sent to Beijing. The importance of goods and revenues to be derived from Đại Việt's formerly flourishing maritime trade was not ignored from the Ming administration. In order to draw revenues from their new province , the Chinese established or revived commercial taxes offices, fishing tax offices, transport offices and salt tax offices. New gold-mining offices were established in 1408 to supervise the extraction and/or taxation of gold. The impositions on the indigenous populations must have been severe, through a 1411 announcement. Private exports of metal and aromatic products were banned in 1416. Valuable artifacts such as gems, jade, gold, pieces of art as well as craftsmen were transported to China. The Chinese had greatly encouraged the development and the use of gold and silver mines. But right after the silver and gold were extracted  they impounded them and sent a fraction of these minerals to Beijing. They also imposed salt taxes, but a slightly heavier tax against those who produced salt in Annam. Yongle also repeatedly exacted from his newly conquered subjects such as local specialties as tropical green feathers, gold, paints, fans, silk fabrics, and a special sandalwood called the "sumu" that was used for building doors in the new palace and from whose bark a red dye was extracted. Through Yongle's reign, Jiaozhi was never able to provide enough rice to support the large occupation force of Chinese troops, with the  consequence that the new province continued to be a drain on Chinese resources, rather than a source of revenue.
