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.
The King of Rome (Latin: Rex Romae) was the chief magistrate of the Roman Kingdom. According to legend, the first king of Rome was Romulus, who founded the city in 753 BC upon the Palatine Hill. Seven legendary kings are said to have ruled Rome until 509 BC, when the last king was overthrown. These kings ruled for an average of 35 years.
