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.
Although Ionia had produced philosophers such as Pythagoras, up to the time of Anaxagoras this new study of knowledge had not spread to Athens. Anaxagoras is famed as the first to introduce philosophy to the Athenians when he moved there in about 480 BC. During Anaxagoras's stay in Athens, Pericles rose to power. Pericles, who was about five years younger than Anaxagoras, was a military and political leader who was successful in both developing democracy and building an empire which made Athens the political and cultural centre of Greece.
