A city-state is a small, independent country that consists of a single city and its surrounding territory. These unique political entities have their own governments and often operate like miniature nations. Famous examples of city-states include Athens and Sparta in ancient Greece, which were known for their distinct cultures and political systems.
City-states thrive on trade and cultural exchange due to their strategic locations. They often have their own laws, military, and economic systems. In modern times, Singapore is a well-known example of a city-state, showcasing how these entities can successfully manage urban living and economic growth while maintaining independence.
