Athens, one of the worldâs oldest cities, has a history of over 3000 years. Details of its founding, though, are not known; the rich mythology of ancient Greeks, though, fills in the blanks. According to the legend, Cecrops was the founder and first King of Athens.
With this system, Pericles succeeded in keeping the courts full of jurors (Ath. Pol. 27.3), and in giving the people experience in public life. As Athens' ruler, he made the city the first and most important polis of the Greek world, acquiring a resplendent culture and democratic institutions.
