We call them “Etruscans”, they called themselves “Rasenna”.
The Etruscans were the inhabitants of what is now Tuscany in the Iron Age. At the height of their civilization, Etruscan settlements stretched from the Po Valley to down to Campania.
The Romans - the inhabitants of a small collection of villages on seven hills while the Etruscans were at their height - both loathed and respected their Etruscan overlords. Many Roman artistic and legal traditions were adopted from Etruscan culture, and Rome’s expansionism was born in part of attempts to secure the city against Etruscan dominance.
In time, the Romans would go on to conquer much of the world they knew. The Etruscans would be largely forgotten, despite the fact that much of their culture would live on in different forms throughout the Roman-influenced world.
