What was the largest city-state in history? In square kilometers (for example, Singapore is the largest city-state in the world with 734 km²) (a city-state is a state that does not have subdivisions, neighborhoods, districts, and others that don't count since they have no power or leader)
One thing I never understood about the subdivision of Türkiye is what the difference is between a metropolitan municipality and a province? (The blue parts are the municipalities and the gray parts are the provinces)
