There were many reasons for not unifying in one
political system:
One of them was the geography, Greece contained many mountainous
terrains, valleys which were separated from each other, many islands where it
was easy to form new towns and settlement, giving birth to many power centers
instead of one
Another reason was the sense of heroism in Greece and to
fulfil that the great Mediterranean, they could sail to wherever they wanted in
the times of need resulting from any kind of crisis and this helped them
establish new colonies all over the Mediterranean.
Third reason was the presence of aristocracy who denied the
establishment of a monarch and each city or state defended their independence.
