independent or autonomous entity whose territory consists of a city From Wikipedia, the free encyclopedia
A city-state is a city that has its own sovereignty, meaning that it is its own country. There were many important city-states in ancient Greece. Nowadays, cities may have differing degrees of self-governance. In order to be considered a city-state, a city must govern itself independently, by regulating its own taxes, or having independent representation at the United Nations.
