Wanyan

The Wanyan (traditional Chinese: 完顏; simplified Chinese: 完颜; pinyin: Wányán; Manchu: ᠸᠠᠩᡤᡳᠶᠠᠨ Wanggiyan; Jurchen script: ), alternatively rendered as Wanggiya, was a clan of the Heishui Mohe tribe living in the drainage region of the Heilong River during the time of the Khitan-led Liao dynasty.

According to tradition passed down via oral transmission, Wugunai was the 6th generation descendant of Hanpu, the founder of the Wanyan clan, who therefore must have lived around the year 900.

He succeeded in settling a dispute between two families without resorting to violence, and as a reward, was betrothed to a worthy unmarried maiden also 60 years old.

Herbert Franke described the narrative provided in the History of Jin as an "ancestral legend" with a historical basis in that the Wanyan clan had absorbed immigrants from Goryeo and Balhae during the 10th century.

[5] Yingge died during the conquest of Helandian (曷懶甸; present-day Hamgyong Province, North Korea) after pacifying the Tumen River basin.

Under his order, Shishihuan (石適歡) led a Wanyan army from the Tumen River basin to subdue rival Jurchen tribes in Helandian and advance southward to chase about 1,800 remnants who defected to the Korean kingdom Goryeo.

However, when Wuyashu's delegates, Aguo (阿聒) and Wulinda Shengkun (烏林答勝昆), arrived in Goryeo, the Koreans killed them and dispatched five large armies led by Yun Kwan to attack Helandian.

After their victory, Mongol declared that people with the surname "Wanyan" were considered to be related to the royal line of the Jin dynasty, and therefore such individuals were to be executed immediately.

[citation needed] For the sake of survival, those people with the surname "Wanyan" either changed the name to Wang or moved to a remote area to avoid capture and execution and used the Manchu format Wanggiyan.
