Looking Internally in the Civilization and Feudalism

[Ares I of Congo 88]

Maybe there could be a mechanic similar to feudal France where another nation can rule lands in that nation but they would be a subject to them and they can seize or confiscate their land but only for a justified reason, this could be achieved maybe if there was things more internal like for example when you play as the US you can see the numerous states inside it and there could be disputes within the nation or like the Kingdom of France in which it looks like its United but if there's a new map mode you can see the many duchies and counties within it and one of them being the English Possessions for example or like the Peerage of England where there are many duchies like York and Lancaster. It would also be cool a civ could be able to divide its land into duchies and counties but within the Kingdom similar to how the United States introduces many states within itself. 

 

            Analyzation: You can see France zoomed out it looks pretty unified but when you can zoom in or go to a new map mode or something you can see the many duchies and counties

I really hope this can be approved
