The Etruscans thrived from about 900 to 100 BCE. Although archaeology has revealed much about their life, even more remains unknown. After the Etruscans were assimilated by the Romans, their written history was lost. Although the Emperor Claudius wrote a 20-volume history of the Etruscans, not a page of this has survived.
Popular ideas that the Etruscans originated in Greece, Turkey or Phoenicia have given way to the idea that they were indigenous to the area where they lived – Etruria. This is the land north of the Tiber River, south of the Po River and west of the Apennine Mountains, comprising the present day Italian regions of Lazio, Tuscany and Umbria.
