The so-called Eight Flags Banner Lord, in fact, is a customary title, in the Qing Dynasty there was no such formal position as "Flag Lord", in fact, the Flag Lord is just a statement for the manager who has the largest number of leaders in the flag.
Throughout the Qing Dynasty, the vast majority of flag owners were actually surnamed Ai Xin Jueluo, while the banner lords of the Upper Three Banners were the emperor himself, and the flag owners of the Lower Five Banners and the other leaders among them were mostly from the clan, and their ancestors were often princes.

The early eight flags system originated from the hunting organization of the Jurchens, and the Nurhaci era reorganized and established the eight flags system, and each flag of the eight flags was set up with a person in charge of the flag, called the flag owner.
In the post-Jin Dynasty, the eminent people among the Khans and the Jurchen nobles each held different flags and served as flag owners.
During the Nurhaci period, Nurhaci himself was in charge of the positive yellow flag and the yellow flag, while Dai Shan mastered the positive red flag and the red flag, the emperor Taiji managed the white flag, Du Du was in charge of the white flag, Mang Gultai was in charge of the blue flag, and Amin was in charge of the blue flag.
Under the influence of Emperor Taiji and the later regency of Dorgon, the eight banners were gradually divided into the upper three banners and the lower five banners, of which the yellow flag, the positive yellow flag and the positive white flag were the upper three banners, and the other five flags belonged to the lower five banners.
The Shangsan Banner belongs to the emperor's personal soldiers, and the yellow flag is respected, and the emperor himself is the flag owner of the Shangsan Banner.
Under the Eight Flags system, three hundred dings is a "cow record", five cattle records are a "Jia La", and five Jia La is a "Gu Shan", and the Gu Shan here is also a "flag", that is to say, the Eight Flags system is also hierarchical like a pyramid.
As for the question of the flag owner, the Three Banners do not need to be guessed and paid attention to, because the Three Banners are the emperor's private soldiers, and whoever becomes the Emperor is the banner master of the Three Banners, which is without any suspense.
However, not all of the three banners in the Shangsan Banner are the descendants of the Ai Xinjue Luo family.
The Qing Dynasty really belonged to the royal family under the jurisdiction of the Three Banners, mainly the concubines who received favors and their mothers-in-law's families, the unmarried princesses and the unvaled princes, as well as the relatives of the empress dowager, and there were no other royal families.
The princess and the prince in the three banners are not married, if the princess is married and the prince is knighted, his flag will also be changed, and the prince is mainly going to go to the five flags.
Although the Lower Five Banners are not as close as the Three Banners and the Emperor, they are still a force that cannot be ignored.
In order to consolidate their own strength, during the Qing Dynasty, they would often let the princes take up positions in the lower five banners, in charge of several collars, and there were several collars in each banner, and the person who mastered the most collars was the flag owner.
The Eight Flags system of the Qing Dynasty is very special, and the Eight Flags is a system of flag management, which organizes everyone into the flag register for convenient management, which is somewhat similar to the ancient armor protection system.
And the personnel in the Eight Banners, although they will stand out in the future, they will still be inferior in front of the flag owners.
It is not that the actual status is lower than that of the flag owner, but more similar to an unwritten rule, just like the most powerful descendants within the clan return to the clan, or they still have to salute the clan elders, which is why the eight flag lords are powerful.
After all, the Eight Flags system is the basis for maintaining the Qing Dynasty, so even if it is the Next Five Banners, the Ai Xin Jue Luo family will not easily relax and give up, and those who control most of the collar are still the descendants of the Ai Xin Jue Luo family.
During the Qing Dynasty, most of the people who served as the actual flag masters were members of the clan and there was basically no one else.
The flag owner is not a hereditary system, but is appointed and assigned by the emperor, and the prince or prince, the county king, the baylor and other people who are enthroned and can hold the majority of the collars automatically become the flag owner of the flag.
