Etruscan civilization is the modern English name given to a civilization of ancient Italy in the area corresponding roughly to Tuscany, western Umbria, and northern Latium. The ancient Romans called its creators the Tusci or Etrusci. Their Roman name is the origin of the terms Tuscany, which refers to their heartland, and Etruria, which can refer to their wider region.
In Attic Greek, the Etruscans were known as Τυρρηνοὶ (Tyrrhēnioi), earlier Tyrsenoi, from which the Romans derived the names Tyrrhēni (Etruscans), Tyrrhēnia (Etruria), and Mare Tyrrhēnum (Tyrrhenian Sea). The Etruscans called themselves Rasenna, which was syncopated to Rasna or Raśna.
As distinguished by its unique language, this civilization endured from the time of the earliest Etruscan inscriptions (ca. 700 BC) until its assimilation into the Roman Republic in the late 4th century BC. At its maximum extent, during the foundational period of Rome and the Roman kingdom, it flourished in three confederacies of cities: of Etruria, of the Po valley with the eastern Alps, and of Latium and Campania.
