List three ways greek city-states created the idea of citizenship.

After a period in Greece called the Dark Ages, cities began sending people outside of Greece to set up (groups of people or other living things). They went to Italy, Spain, North Africa, and western Asia n order to spread Greek culture. The (groups of people or other living things) traded grain, metals, fish, timber and slaves with Greece.The growth in trade led to the exchanging products (that are bought and sold) for money rather than more products (that are bought and sold). As industry grew, people became artists (who make things) based on what products their area supplied. Greek city-states were known as a polis. The acropolis was the main gathering place. The acropolis also served as a religious center where temples and changes were built to honor their many gods and goddesses. The agora served as a market place and a meeting place. Most city-states were small, but Athens had as many as 300,000 people. 
The polis was run by its people. (living in a country you were born in, or having the same rights in a country as someone who was born there) meant: 
you were a member of a political community you were a native born man you owned land
