What is the origin of the Etruscan civilization?
There are three main hypotheses as to the origins of the Etruscan civilization in the Early Iron Age.
Where did the Etruscan civilization settle?
The Etruscan civilization settled in the area corresponding roughly to Tuscany, western Umbria, northern Lazio with offshoots also to the north in the Po Valley, in the current Emilia-Romagna.
Are there any other interesting aspects about the Etruscan civilization besides where they settled and their origin?
The Etruscans called themselves Rasenna, which was syncopated to Rasna or Raśna, while the ancient Romans referred to the Etruscans as the Tuscī or Etruscī.

Question: Did the Etruscans have any problems with other people/civilizations?
