Jianzhou Jurchens
The leadership of the Jianzhou confederacies found its lineage from the Odori Jurchens whose leader Mongke Temur was renown by both the Ming and by the Yi. Giocangga, Nurgaci grandfather, claimed to be a fourth-generation descendant of Mongke Temur. The elite members of the Jurchen lineage possessed the Chinese characters for Jiagu in their names. In 1588 Nurhaci brought the Wanggiya tribe and Donggo tribe together. The unification of the Jianzhou Jurchens became a stepping stone for Nurhaci to expand his power throughout southern and central Manchuria, and to create a truly unified Manchu state. The very name Manchu (Jurchen: manju) was perhaps an old term for the Jianzhou Jurchens.
