The Nguyễn dynasty was the final ruling family of Vietnam. They led the country from 1802 until 1883. 
The story of this family began long before they became emperors. In the 1500s, the Nguyễn clan held much power in Vietnam. One man named Nguyễn Hoàng moved to the far south in 1558. 
In 1802, the dynasty officially began with Emperor Gia Long. He took the throne after defeating the Tây Sơn dynasty. This started a new era of imperial rule. Later, Emperor Minh Mạng ruled in the 1830s. Under his rule, the empire had the official name Đại Nam.
Things changed when France arrived in the mid-1800s. The French began a campaign to take control of the land. In 1862, the Treaty of Saigon forced the dynasty to give up parts of Southern Vietnam. This area became a French colony called Cochinchina. 

The dynasty faced many more changes during World War II. In 1945, the last emperor was named Bảo Đại. With help from Imperial Japan, he ended the French treaty for a short time. He proclaimed the Empire of Vietnam in August 1945. 

The Nguyễn dynasty was the final imperial ruling family of Vietnam. This dynasty governed a unified Vietnam independently from 1802 until 1883. 
The roots of the dynasty lie in the powerful Nguyễn clan. This clan originated in the Thanh Hóa Province. They had held political influence since the tenth century. In 965, Nguyễn Bặc served as the first grand chancellor under the Đinh dynasty. Later, Nguyễn Thị Anh served as a regent for the child emperor Lê Nhân Tông. By the 16th century, the clan became major players in Vietnamese politics.
In 1558, a man named Nguyễn Hoàng moved to the southern frontier. He was appointed the lord of Thuận Hóa by Emperor Lê Anh Tông. This move created a division in the country. The Trịnh clan held power in the North. The Nguyễn clan established a separate dominion in the South. 
The transition to imperial rule followed a period of intense conflict. The Tây Sơn rebellion began in 1774 and challenged the Nguyễn lords. This led to the Tây Sơn–Nguyễn war, which lasted until 1802. After defeating the Tây Sơn dynasty, Nguyễn Phúc Ánh ascended the throne. He became Emperor Gia Long in 1802. 
As the empire grew, its official names also changed. Under Emperor Minh Mạng in 1839, the name became Đại Việt Nam. This was later shortened to Đại Nam, meaning 'Great South'. 
In the mid-19th century, French intervention changed the dynasty's power. The Cochinchina Campaign began in 1858. This led to the French occupation of Southern Vietnam. In 1862, the Treaty of Saigon made the southern territory a French colony called Cochinchina. 

The end of the dynasty was marked by the chaos of World War II. In 1940, Japan occupied Indochina. On March 9, 1945, Japan overthrew the French administration. The last emperor, Bảo Đại, proclaimed the Empire of Vietnam with Japanese support. This state was nominally independent but acted as a Japanese puppet state.
