The Umbri were an ancient people, considered an Italic people, attested during the Iron Age in inner central Italy, approximately between the middle Tiber river and the central Apennines. A region called Umbria still exists and is now occupied by Italian speakers. It is somewhat smaller than the ancient Umbria. Most ancient Umbrian cities were settled in the 9th-4th centuries BC on easily defensible hilltops. Umbria was bordered by the Tiber and Nar rivers and included the Apennine slopes on the Adriatic. The ancient Umbrian language belongs to the Osco-Umbrian branch of the Italic languages, an Indo-European subfamily that also includes the Latino-Faliscan languages.
