Bordered Blue Banner

The Bordered Blue Banner (Chinese: 镶蓝旗) was one of the Eight Banners of Manchu military and society during the Later Jin and Qing dynasty of China. It was one of the lower five banners. According to the general annals of the Eight Banners, the Bordered Blue Banner was one of the banners located on the south right wing (blue banners were located southward, the Plain Blue Banner being on the south left wing).

This banner was first commanded by Amin (second of the Four Senior Beile), the eldest son of Šurhaci, and then transferred to his younger brother Jirgalang. After Amin lost favor with Hong Taiji, the Bordered Blue Banner was assigned to Jirgalang. By the bloodline of its commanders, the Bordered Blue Banner was the most remote of the Eight Banners as all the other banners were led by descendants of Nurhaci, and was usually seen as the last of the Eight Banners although there were no concrete laws to officially acknowledge this status.

Some Haixi Jurchens were incorporated into this banner after the defeat of the Haixi Jurchens by the Jianzhou Jurchens.
