Nguyễn dynasty
The Nguyễn dynasty, the final imperial family of Vietnam, was founded by the House of Nguyễn Phúc. It governed a unified Vietnam as an independent state from 1802 until the French protectorate began in 1883. The empire grew to encompass parts of what are now Southern Vietnam, Cambodia, and Laos, driven by the ongoing Nam tiến expansion and conflicts like the Siamese–Vietnamese wars. French military pressure forced the dynasty to cede sovereignty over sections of Southern Vietnam in 1862 and 1874. After 1883, the Nguyễn emperors held only nominal authority over the French protectorates of Annam (Central Vietnam) and Tonkin (Northern Vietnam). In 1945, with backing from Imperial Japan, the last emperor, Bảo Đại, annulled the protectorate treaty with France and briefly proclaimed the Empire of Vietnam, which lasted until August 25 of that year.
The Nguyễn Phúc clan had controlled extensive territory in Southern Vietnam as the Nguyễn lords from the 16th century, before defeating the Tây Sơn dynasty and establishing imperial rule in the 19th century. Gia Long began the dynastic rule in 1802 after ending the Tây Sơn. France gradually absorbed the dynasty through a series of unequal treaties following the 1858 Cochinchina Campaign, which occupied southern Vietnam. The 1862 Treaty of Saigon made that territory the French colony of Cochinchina, and the 1863 Treaty of Huế granted France access to ports and control over foreign affairs. The 1883 and 1884 Treaties of Huế divided remaining territory into the protectorates of Annam and Tonkin under nominal Nguyễn rule. In 1887, these areas, along with Cambodia, formed French Indochina. During World War II, Japan occupied Indochina with French collaboration in 1940, then overthrew the French administration on 9 March 1945. Two days later, the Nguyễn dynasty proclaimed independence for its protectorates, and regained Cochinchina on 14 August 1945. The resulting Empire of Vietnam under Bảo Đại was a Japanese puppet state. It ended with Bảo Đại’s abdication after Japan’s surrender and the August Revolution led by the Việt Minh in August 1945, concluding 143 years of Nguyễn rule. Bảo Đại later returned as head of state of the State of Vietnam from 1949 until it became a republic in 1955.

Lore & Background
The House of Nguyễn Phúc established control over large amounts of territory in Southern Vietnam as the Nguyễn lords (1558–1777, 1780–1802) by the 16th century before defeating the Tây Sơn dynasty and establishing their own imperial rule in the 19th century. The dynastic rule began with Gia Long ascending the throne in 1802, after ending the previous Tây Sơn dynasty. In 1802, Nguyễn Phúc Ánh established the Nguyễn dynasty. In the second year of his rule, he asked the Jiaqing Emperor of the Qing dynasty to confer on him the title 'King of Nam Việt / Nanyue' after seizing power in Annam. The Qing Emperor refused because the name was related to Zhao Tuo's Nanyue, which included the regions of Guangxi and Guangdong in southern China. The Qing Emperor, therefore, decided to call the area 'Việt Nam' instead. Between 1804 and 1813, the name Vietnam was used officially by Emperor Gia Long. In 1839, under the rule of Emperor Minh Mạng, the official name of the state was Đại Việt Nam, and it was shortened to Đại Nam.
Reader's Guide
The Nguyễn dynasty was gradually absorbed by France over the course of several decades in the latter half of the 19th century, beginning with the Cochinchina Campaign in 1858 which led to the occupation of the southern area of Vietnam. A series of unequal treaties followed; the occupied territory became the French colony of Cochinchina in the 1862 Treaty of Saigon, and the 1863 Treaty of Huế gave France access to Vietnamese ports and increased control of its foreign affairs. Finally, the 1883 and 1884 Treaties of Huế divided the remaining Vietnamese territory into the protectorates of Annam and Tonkin under nominal Nguyễn Phúc rule. In 1887, Cochinchina, Annam, Tonkin, and the French Protectorate of Cambodia were grouped together to form French Indochina. The Nguyễn dynasty remained the formal emperors of Annam and Tonkin within Indochina until World War II. Japan had occupied Indochina with French collaboration in 1940, but as the war seemed increasingly lost, Japan overthrew the French administration on 9 March 1945 and the Nguyễn dynasty proclaimed independence for its constituent protectorates two days later. It also regained Cochinchina on 14 August 1945. The Empire of Vietnam under Nguyễn Emperor Bảo Đại was a nominally independent state but actually a Japanese puppet state during the last months of the war. It ended with the abdication of Bảo Đại following the surrender of Japan then August Revolution led by the communist Việt Minh in August 1945. This ended the 143-year rule of the Nguyễn dynasty.
