What contribution did Ancient Greece make to the development of civilization?

This contribution is difficult to fully appreciate. Ancient Greece became the basis of ancient civilization, and that, in turn, is the basis of modern European civilization. Greece gave us the concept of civil society, which took shape within the city-states of policies. It was imperative for the Greeks to be actively involved in the political life of the place where he lives. The influence of the culture of the Greeks is no less important. To this day, we see these motives in paintings, plays, music, which we later recognize as classics.
