Page "Umbria" Paragraph 8

The Etruscans were the chief enemies of the Umbri, and the Etruscan invasion went from the western seaboard towards the north and east ( lasting from about 700 to 500 BC ), eventually driving the Umbrians towards the Apenninic uplands and capturing 300 Umbrian towns.

Nevertheless, the Umbrian population does not seem to have been eradicated in the conquered districts.
