The second important institution was the boule, or Council of Five Hundred. The boule was a group of 500 men, 50 from each of ten Athenian tribes, who served on the Council for one year
The third important institution was the popular courts, or dikasteria. Every day, more than 500 jurors were chosen by lot from a pool of male citizens older than 30.
Despite the small size of their city-states, these ancient Greeks created a civilization that was the source of Western culture. Socrates, Plato, and Aristotle established the foundations of Western philosophy. Western literary forms are largely derived from Greek poetry and drama.
The Greeks were unable to rise above the rivalries that caused them to fight each other and undermine their civilization. Although the Greeks lost their freedom to Philip II, Greek culture did not die. A new age, known as the Hellenistic era, eventually came into being. That era began with the conquest of the Persian Empire by Alexander the Great
Athens has a unique place in human history. As the people who pioneer the arts of history, philosophy and theatre, who attempt the first radical version of democracy, and who achieve a degree of perfection in architecture, sculpture and pottery, the Athenians have rightly acquired an almost legendary status.
After democracy,greek people still belived in the gods and goddess, but it was really separated. God was now something in what they just believed, it didn't influence their lives as before.
