The
Eight Banners (in
Manchu:
jakun gusa, ) were administrative/military divisions under the
Qing dynasty into which all
Manchu households were placed. In war, the Eight Banners functioned as armies, but the banner system was also the basic organizational framework of all of Manchu society. Created in the early 17th century by
Nurhaci, the banner armies played an instrumental role in his unification of the fragmented
Jurchen people (who would later be renamed the
Manchus under Nurhaci's son
Hong Taiji) and in the Qing dynasty's
conquest of the
Ming dynasty. As
Mongol and
Han Chinese forces were incorporated into the growing Qing military establishment, the Mongol Eight Banners and Chinese Eight Banners were created alongside the original Manchu banners. The banner armies were considered the elite forces of the Qing military, while the remainder of imperial troops were incorporated into the vast
Green Standard Army. Membership in the banners became hereditary, and bannermen were granted land and income. After the defeat of the Ming dynasty, Qing emperors continued to rely on the Eight Banners in their subsequent military campaigns. After the
Ten Great Campaigns of the
Qianlong Emperor, the quality of banner troops gradually decreased, and by the 19th century the task of defending the empire had largely fallen upon regional armies such as the
Xiang Army. Over time, the Eight Banners became synonymous with Manchu identity even as their military strength vanished.
