Itu

Yitong takes its name from the river that flows north through the country south of the Songhua. The name, rendered in several forms, comes from a Manchu word associated with a powerful river. Forest and river valleys formed the setting of Jurchen communities in this region. In 1618 Nurhaci defeated Yehe Jurchen and Mongol forces along the Yitong, bringing the river country into the expanding Later Jin realm.
