Chieftain of one branch of the Juchen (later called Manchu ), whose attack on China in 1618 presaged his son Dorgon 's conquest.
Nurhachi first defeated a rival in his own tribe and then subdued the other four Juchen tribes in his immediate area. During this time, he also established a Manchu state and enlisted the scholar Erdeni to create a Manchu writing system. He organized his troops under the Banner system . In 1616 Nurhachi proclaimed himself khan and called his dynasty Jin, harking back to the Juchen Jin dynasty of the 12th century. In 1626 he was defeated by the Chinese and died of battle wounds.
