Lê dynasty in the context of "Grand Secretaries"

Temple names are posthumous titles accorded to monarchs of the Sinosphere for the purpose of ancestor worship. The practice of honoring monarchs with temple names began during the Shang dynasty in China and had since been adopted by other dynastic regimes in the Sinosphere, with the notable exception of Japan. Temple names should not be confused with era names (年號), regnal names (尊號) or posthumous names (謚號).

Modern academia usually refers to the following rulers by their temple names: Chinese monarchs from the Tang to the Yuan dynasties, Korean rulers of the Goryeo (until AD 1274) and Joseon dynasties, and Vietnamese rulers of the Lý, Trần, and Later Lê dynasties (with the Hồ and Later Trần dynasties as exceptions).

The Nguyễn lords (Vietnamese: Chúa Nguyễn, 主阮; 1558–1777, 1780–1802), also known as the Nguyễn clan (Vietnamese: Nguyễn thị; chữ Hán: 阮氏), were Nguyễn dynasty's forerunner and a feudal noble clan ruling southern Đại Việt in the Revival Lê dynasty. The Nguyễn lords were members of the House of Nguyễn Phúc. The territory they ruled was known contemporarily as Đàng Trong (Inner Realm) and known by Europeans as the Kingdom of Cochinchina and as Kingdom of Quảng Nam (Vietnamese: Quảng Nam Quốc; chữ Hán: 廣南國) by Imperial China, in opposition to the Trịnh lords ruling northern Đại Việt as Đàng Ngoài (Outer Realm), known as the "Kingdom of Tonkin" by Europeans and "Kingdom of Annam" (Vietnamese: An Nam Quốc; chữ Hán: 安南國) by Imperial China in bilateral diplomacy. They were officially entitled, in Sino-Vietnamese, the Nguyễn Vương (chữ Hán: 阮王) in 1744 when lord Nguyễn Phúc Khoát self-proclaimed himself to elevate his status equally to Trịnh lords's title known as the Trịnh Vương (Vietnamese: Trịnh Vương; chữ Hán: 鄭王). Both Nguyễn and Trịnh clans were de jure subordinates and fief of the Lê dynasty. However, the de jure submission of the Nguyễn lords to the Trịnh lords ended in 1627 sparked the war between them.

While they recognized the authority of and claimed to be loyal subjects of the revival Lê dynasty, they were de facto rulers of southern Đại Việt. Meanwhile, the Trịnh lords ruled northern Đại Việt in the name of the Lê emperor, who was in reality a puppet ruler. They fought a series of long and bitter wars that pitted the two halves of Vietnam against each other. The Nguyễn were finally overthrown in the Tây Sơn wars, but one of their descendants would eventually come to unite all of Vietnam. Their rule consolidated earlier southward expansion into Champa and pushed southwest into Cambodia.

The Tây Sơn dynasty (Vietnamese: [təj ʂəːn]; Vietnamese: "Nhà Tây Sơn" or "Triều Tây Sơn", (chữ Hán: 朝西山; Chữ Nôm: 茹西山), officially Đại Việt (Chữ Hán: 大越), was an imperial dynasty of Vietnam. It originated in a revolt led by three peasant brothers with the surname Nguyễn, rebelling against the Lê dynasty, Trịnh lords and Nguyễn lords (no relation). The Tây Sơn would later be succeeded by the Nguyễn dynasty.

The Tây Sơn dynasty ended the century-long war between the Trịnh and Nguyễn families, overthrew the Lê dynasty, and united the country for the first time in 200 years. They acknowledged Qing suzerainty and gained recognition from the Qianlong Emperor as the legitimate rulers of Vietnam. Under the most prominent of the Tây Sơn brothers Nguyễn Huệ (Emperor Quang Trung) Vietnam experienced several years of relative peace and prosperity. But Quang Trung died relatively young at the age of 40 and his successor Cảnh Thịnh, aged 9, was unable to prevent civil conflict among the Tây Sơn court which allowed the last Nguyễn lord Nguyễn Ánh to retake the south of Vietnam, extinguish the Tây Sơn and establish the Nguyễn dynasty.

Lê Lợi (Vietnamese: [le lə̂ːjˀ], chữ Hán: 黎利; 10 September 1385 – 5 October 1433), also known by his temple name as Lê Thái Tổ (黎太祖) and by his pre-imperial title Bình Định vương (平定王; "Prince of Pacification"), was a Vietnamese rebel leader who founded the Later Lê dynasty and became the first emperor of the restored kingdom of Đại Việt after the country was conquered by the Ming dynasty. In 1418, Lê Lợi and his followers rose up against Ming rule. He was known for his effective guerrilla tactics, including constantly moving his camps and using small bands of irregulars to ambush the larger Ming forces. Nine years later, his resistance movement successfully drove the Ming armies out of Vietnam and restored Vietnamese independence. Lê Lợi is among the most famous figures of Vietnamese history and one of its greatest heroes.

The Mạc dynasty (Vietnamese: Nhà Mạc/triều Mạc; Hán-Nôm: 茹莫/朝莫) (1527–1677), officially Đại Việt (Chữ Hán: 大越), was a Vietnamese dynasty which ruled over a unified Vietnam between 1527 and 1540, and northern Vietnam from 1540 until 1593. The Mạc dynasty lost control over the capital Đông Kinh (modern Hanoi) for the last time in its wars against the Later Lê dynasty and the Trịnh Lords in 1592. Subsequent members of the Mạc dynasty ruled over the province of Cao Bằng with the direct support of the Chinese Ming and Qing dynasties until 1677 (with members of the Mạc dynasty accepted as officials of the Later Lê dynasty from 1627).

Spoken and written Vietnamese today uses the Latin script-based Vietnamese alphabet to represent native Vietnamese words (thuần Việt), Vietnamese words which are of Chinese origin (Hán-Việt, or Sino-Vietnamese), and other foreign loanwords. Historically, Vietnamese literature was written by scholars using a combination of Chinese characters (Hán) and original Vietnamese characters (Nôm). From 111 BC up to the 20th century, Vietnamese literature was written in Văn ngôn (Classical Chinese) using chữ Hán (Chinese characters), and then also Nôm (Chinese and original Vietnamese characters adapted for vernacular Vietnamese) from the 13th century to 20th century.

Chữ Hán were introduced to Vietnam during the thousand year period of Chinese rule from 111 BC to 939 AD. Texts in Vietnam were written using chữ Hán by the 10th century at the latest. Chữ Hán continued to be used as the official administrative script until the 19th century with the exception of two brief periods under the Hồ (1400–1407) and Tây Sơn (1778–1802) dynasties when chữ Nôm was promoted. Chữ Nôm is a blend of chữ Hán and unique Vietnamese characters to write the Vietnamese language. It may have been used as early as the 8th century but concrete textual evidence dates to the 13th century. Chữ Nôm never supplanted chữ Hán as the primary writing system and less than five percent of the educated Vietnamese population used it, primarily as a learning aid for chữ Hán and writing folk literature. Due to its unofficial nature, chữ Nôm was used as a medium for social protest, leading to several bans during the Lê dynasty (1428–1789). In spite of this, a sizable body of literature in chữ Nôm had accumulated by the 19th century, and these texts could be orally disseminated by individuals in villages.

Tusi, often translated as "headmen" or "chieftains", were hereditary tribal leaders recognized as imperial officials by the Yuan, Ming, and Qing dynasties of China, and the Later Lê and Nguyễn dynasties of Vietnam. They ruled certain ethnic minorities in central China, western China, southwestern China, and the Indochinese peninsula nominally on behalf of the central government. As succession to the Tusi position was hereditary, these regimes effectively formed numerous autonomous petty dynasties under the suzerainty of the central court. This arrangement is known as the Tusi System or the Native Chieftain System (Chinese: 土司制度; pinyin: Tǔsī Zhìdù). It should not be confused with the Chinese tributary system or the Jimi system.

Tusi regimes were located primarily in Yunnan, Guizhou, Tibet, Sichuan, Chongqing, the Xiangxi Prefecture of Hunan, and the Enshi Prefecture of Hubei. Tusi entities were also established in the historical dependencies and frontier regions of China in what is today northern Myanmar, Laos, and northern Thailand. The Vietnamese Later Lê and Nguyễn dynasties also implemented the Tusi system.
