Ancient Greece
Ancient greece
Greece was divided into independent city-states. Four of the most powerful city states were Athens, Sparta, Corinth, and Argos.
The most famous and powerful of all the city states of ancient Greece were Sparta and Athens.
The city-states of Greece emerged in around 750 BCE, and reached their peak in the 5th Century BCE.
Most of Greece's history was located in the city of Athens and Sparta, who were at the time two city-states.
The loyalty to the city-states was greater than the loyalty to any larger conception of Greece. As a result, city-states would only fight or mobilize in cases where the individual city-state was jeopardized, not out of solidarity with other city-states.
Ancient Greece would be considered a large number of independent and semi-independent city-states, but Modern Greece is a nation-state, a republic. Modern city states include places like Vatican City, Monaco, Liechtenstein, or Nauru.
No one - there was no king of Greece. The Greek nomadic tribes settled in various places in Greece and established their own city states which remained independent, spreading around the Mediterranean and Black seas as over 2,000 independent city-states.
