Wanyan

Wanyan, written in Chinese as 完顏, is a historic Jurchen and Manchu clan name. It was one of the leading lineages of the Jurchen people and played a central role in the rise of the Jin dynasty in northern China.

Origins and historical role: The Wanyan clan rose to prominence in the 11th century, with Wanyan Aguda founding the Jin dynasty in 1115 after uniting the Jurchen tribes. Under Wanyan rule, the Jin expanded their territory, ultimately defeating the Liao and Northern Song states and establishing a powerful polity that controlled large parts of northern China until the Mongol conquest. The dynasty lasted until 1234, when it was conquered by the Mongol Empire. The Wanyan rulers adopted the imperial title of Jin Emperor and left a lasting imprint on regional administration and military organization.

Modern usage and legacy: Today, Wanyan remains a recognized Manchu clan name. As a surname, it is relatively rare in present-day China and among Manchu communities, with various transliterations in use.

Notable figures: The best-known member of the Wanyan clan is Wanyan Aguda, also known as Emperor Taizu of Jin, founder of the Jin dynasty.
