Jurchens

The Jurchens (Jurchen language: jušen) were a Tungusic people who inhabited the region of Manchuria (present-day Northeast China) until the 17th century, when they adopted the name Manchu. They established the Jin Dynasty (1115–1234) (Ancun gurun in ancient Jurchen and Aisin gurun in Standard Manchu) between 1115 and 1122, which lasted until 1234 with the arrival of the Mongols.
