Neyen
Neyen was a Jurchen tribe named for a river in the upper Songhua region, among the Changbai Mountain tribes. Its people later entered Ming frontier administration alongside the Jianzhou Jurchens.
In 1593 Neyen joined the Yehe-led coalition against Nurhaci. After defeat at Gure, its leaders Sowen and Sekeshi gathered seven villages at the fortified camp of Fotuohe. Nurhaci sent Eidu, Gagai and Anfiyanggū with a thousand men; after a three-month siege the camp fell and both leaders were killed. Neyen was absorbed into his realm and later the Eight Banners.
