As the title says, I think anyone agrees thats, ok, it's viable and make sense the King nd lords keep fighting for a time after they lost all their lands, after all they don't become poor and lose all respect from night to day.
So, I agree the Kingdom may still be around for a time after being conquered.
But, give us a option while talking to the Kingdom/Empire Leader some kind of banter or persuasion to ask them to give up their crown, which would means, the Faction would be "destroyed/ dissolved" whatever term you prefer. On this negotiations you could even promise to embrace all clans in promises of land and they would give an option to accept your offer to join or not, if not they would scatter arund the world. But if the King acepts dissolve their crown then the Kingdom is "over" until a rebellion appear to make it alive again
