How can there be more free city states around the world with a POD during or after WWI
How can there be more free city states around the world with a POD during or after WWI
A few cities that I think have some sort of shot of becoming city-states:
The Emirates of the UAE not uniting in to begin with
Danzig
Trieste
Hamburg
Konigsburg
Jerusalem
Goa--if they can hold out long enough
Pusan (a 'Taiwanesque' situation)
EDIT: According to Wiki, Singapore, Monaco and the Vatican are the only city states today. What about Andorra and San Marino? I thought they were city-states too.
The problem are resources. City (states) require a lot of resurces they can't produce on their own. It wasn't a problem in ancient Greece where cities were small and people didn't require much beyond food and basic metalurgy. Imagine feeding a city of 1 million people. To grow it on it's own it would require a lot of land and non-urban population to work the land. Then it's all sorts of modern gadgets, from phones to cars. All require resources, which will likely have to be imported either in finished form or as raw resources to be processed. Then there is energy. You can deal with that to a degree with renewable sources (if available) or nuclear power (requiring specialized equipemnt and fuel). Import all that. How is city going to pay for that? It can do it by exporting finished goods or service industry. Exporting goods require strong industry, further eating into population. Service industry is very bubbly and can implode at any moment.
IMO they are simply not feasible. Singapore is only true city-state but they managed to find a ballance on how to pay for everything.
