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.
For the ancient king, see Alexander the Great. Alexander (Greek: á¼Î»Î­Î¾Î±Î½Î´ÏÎ¿Ï, AlÃ©xandros; 1 August 1893 â 25 October 1920) was King of Greece from 11 June 1917 until his death from the effects of a monkey bite at the age of 27. The second son of King Constantine I, Alexander was born in the summer palace of Tatoi, on the outskirts of Athens.
