Herodotus was a Greek historian and geographer from the Greek city of Halicarnassus, part of the Persian Empire and a later citizen of Thurii in modern Calabria, Italy. He is known for having written the Histories – a detailed account of the Greco-Persian Wars. Herodotus was the first writer to perform systematic investigation of historical events. He has been described as "The Father of History", a title conferred on him by the ancient Roman orator Cicero.
