 What is a modern city that is large enough to be a city-state?
What cities in the post-Brexit era could learn from a 14th-century trading bloc As you fly from the country now known as Germany to Britain, the coastal geography of northern European cities gently unfurls. By their nature cities along coasts and rivers developed so they could be open to trade with each other. Yet look at any city of Mitteleuropa and you'll see the many different names it has had as borders and regimes have shifted with the sands of time. "So it is not unrealistic to think of cities as discrete entities that compete and collaborate with each other, independently from the states to which they belong."
