Donggo
Donggo was one of the Jianzhou Jurchen groups of the wooded country east of Liaoyang. Its name was associated with the river now known as the Dayarhu. In the late sixteenth century Nurhaci expanded his authority among the Jianzhou peoples from his base at Hetu Ala. In 1616 he proclaimed the Later Jin there, establishing a new state in the Jurchen homelands.
