Answer:
<h3>Hellenistic Era witnessed a shift from the polis to the cosomopolis.</h3>
Explanation:
It is believed that Athens reached its greatest political and cultural heights during the Classical Period or the period of Alexander the Great.
Development of the democratic system of government under Pericles, the building of the Parthenon on the Acropolis,and the founding of the philosophical schools of Socrates and Plato all emerged during this period.
After the end of this period Hellenistic Era begun. The former period left Hellenistic era with a great deal of advanced arts, philosophy, and literature, and also immense knowledge about the outside world.
So during the Hellenistic Era, the Greek society transformed from the confined and introverted city-states or 'polis' to an open and cosmopolitan culture which had its influence over the entire eastern Mediterranean and Southwest Asia.
Travelers from all over the world came to Greece to learn and acquire Greek knowledge. It became a multi-learning hub. Greek culture and learning became pre-eminent in the Mediterranean and Asia Minor during this period.The blending of western and eastern cultures eventually forced Greeks to give up their traditional polis-centered worldview.
Thus, it can be rightly said that during the Hellenistic Era, the Greeks witnessed a shift from polis to a cosmopolitan outlook.
