Plain Blue Banner

The Plain Blue Banner was one of the Eight Banners of Manchu military and society during the Later Jin and Qing dynasty of China. As part of the original Four Banners before its expansion, the first commander was Surhaci when he was assigned the Plain Blue Banner by his older brother and Jianzhou Jurchen Leader Nurhaci. After Surhaci lost favor, Nurhaci assigned the Plain Blue Banner to his 5th son, Manggūltai. After Nurhaci's death, Daišan used his influence to make the princes and generals to agree on Hong Taiji's accession as Khan. Although Hong Taiji had become Khan, Manggūltai, along with Daišan and Amin continued to take turns as assistant administrators until 1629, when Hong Taiji had begun to consolidate power.
Manggūltai lost favor and rumored to be drunk and drew his knife on Hong Taiji to which he had to hand over the Plain Blue Banner to Hong Taiji, which was the third strongest banner at that time. In this way, Hong Taiji slowly eliminated his competitor's powers. With Daisan also withdrawing his Senior Beile seat next to Hong Taiji, he truly sits alone facing the south direction with superior power above all other beiles.
