I think the strong prewar hatred of communism could actually make it more interesting. I mean, we know there's gonna be a significant Chinese population there, and Canada was getting pretty mad at the US after the whole Alaska debacle. I think a communist faction popping up either out of Chinese loyalism or anti-America spite wouldn't be too out there. And plus I think there could be some people who genuinely think communism is the only way for a society to survive somewhere as unforgiving as the wasteland. It takes so much, we have to share what we have. 

It'd certainly be a polarizing faction, that's for sure. But we totally don't have to go with it. I'm just spitballing, and honestly don't know all that much about fallout lore.

Oh! Let's not go European with the kingdom, but Chinese instead. Thus the kingdom was formed around an "Emperor," and he has his warriors to defend him. They have conquered the northwest but have not pushed south.
