Another term for a city and the surrounding land it controls is O city-state
O empire
O kingdom
O nation-state

I think that would be city-state.

An Empire and Kingdom we all know they these control big amount of lands which is not really what it surrounds it, and a nation-state is very close, but I think inside of a nation-state could be more cities, which I don’t think is the right answer.

So what we got only is the city-state.

I hope this helps you.
