  • A city-state is a sovereign state consisting of a city and its dependent territories.[1][2] Historically this included famous cities like Rome, Athens, Carthage[2] and the Italian city-states during the Renaissance, but today only a handful of sovereign city-states exist, with some disagreement as to which states should and should not be considered as city-states.
