Nguyen

Nguyễn (sometimes abbreviated as Ng̃) is the most common surname of the Vietnamese people.

Outside of Vietnam, the surname is commonly rendered without diacritics as Nguyen.

By some estimates 30 to 39 percent of Vietnamese people bear this surname.

Origin and usage
Nguyễn is the transcription of the Sino-Vietnamese pronunciation of the character 阮, which originally was used to write a name of a state in Gansu or an ancient Chinese instrument Ruan. The same Chinese character is often romanized as Ruǎn in Mandarin and as Yuen in Cantonese.

The first recorded mention of a person surnamed Nguyễn is a description dating AD 317, of a journey to Giao Châu undertaken by Eastern Jin dynasty officer Nguyễn Phu and his family. Many events in Vietnamese history have contributed to the name's prominence. In 1232, after usurping the Lý dynasty, Trần Thủ Độ forced the descendants of the Lý to change their surname to Nguyễn. When Hồ Quý Ly overturned the Trần dynasty, he killed many of their descendants so when the Hồ dynasty collapsed in 1407, many of his descendants changed their surname to Nguyễn in fear of retribution. In 1592, on the collapse of the Mạc dynasty, their descendants changed their surname to Nguyễn. In late 16th century, the Tư Mã clan from Thanh Hóa changed to Nguyễn and settled in Cochinchina. When the Nguyễn dynasty (the descendants of the Nguyễn Lords) took power in 1802, some of the descendants of the Trịnh Lords fearing retribution changed their surname to Nguyễn, while others fled north into China.

The Nguyen surname also appears in China but is significantly less common than its Vietnamese counterpart.

Subfamilies
In Vietnamese tradition, people are referred to by their personal names and not by their family names even in formal situations. However, some groups distinguish themselves from other Nguyễn by passing elements of their names that are usually considered middle names to their children. This practice is more common with male than with female children. Some of the prominent subgroups within the Nguyễn family are:

Changes of family name
There have been various points in Vietnam's history at which people have changed their family name to Nguyễn. When the Lý dynasty fell in 1232, Trần Thủ Độ, who orchestrated its overthrow, forced descendants of the Lý dynasty to adopt the name due to the naming taboo surrounding Trần Lý, grandfather to emperor Trần Cảnh.

From 457 to Hồ Quý Ly (1401), in Hải Dương and a part of Haiphong today there is the district of the Phí family (Vietnamese: huyện Phí Gia). At the end of the Lý and the Trần dynasty there were many people who changed their names to Nguyễn and Nguyễn Phí. By the Lê dynasty, the court changed the name of the district to Kim Thành.

When the Mạc dynasty fell in 1592, their descendants changed their family name to Nguyễn.

Trần Quang Diệu (like his wife Bùi Thị Xuân) worked as a major officer for the Tây Sơn dynasty, against Nguyễn Ánh. After the Tây Sơn dynasty was defeated, his children adopted various names or changed names (one of them into Nguyễn) in order to flee retaliation.

Historically in Vietnam and many East Asian countries, the rulers may let their courtiers share their family name as a reward for their loyalty. Many officials thereby changed their name to match that of the last Nguyễn dynasty (1802–1945). Civilians also adopted the name during the Trịnh–Nguyễn Civil War for purposes of social climbing, having migrated from the north to the south. Even the Tây Sơn Brothers changed their name to Nguyễn from Hồ.
