Nurhaci's Banners

Origin
Nurhaci ascended from chief of the Aisin Gioro clan to become leader of all the Jurchen tribes, reorganized as the Manchu. In a stroke of pure political cunning, Nurhaci's government emphasized shared cultural traits like dress and diet to get competitors like the Mongols and Yehe to cooperate.

Not content with a handful of tribes under one rule, Nurhaci's forces wrestled the Ming Dynasty for territory. To effectively wage war across China without tribal infighting, Nurhaci implemented the Eight Banners system. Regiments were divided by ethnicity such as Han and Mongols, allowing soldiers to pledge allegiance to the khan but faithfully retain their cultural hallmarks. These divisions also existed in civilian society, persisting for centuries after Nurhaci's passing.

Effects
Creates trust and solidarity between opposing peoples, defined by the original flag-bearers. Brings people together by highlighting their similarities, allowing them to communicate without quarrel. Each banner also reinforces long-held traditions within their own society, reviving a fervent adherence to old rituals in the latest generations.

However, it also magnifies an extreme aversion towards others not within their direct lifestyle or line of communication. While cooperative with their fellow flag-bearers, they will attempt to oppress or utterly destroy outsiders for their own security.
