八旗制度
As Mongol and Han forces were incorporated into the growing Qing military establishment, the Mongol Eight Banners and Han 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 mid-18th century the quality of the banner armies declined. Their failure to suppress the Taiping Rebellion of the mid-19th century ruined their reputation. By the late 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.
