A Late Antique region and administrative unit of central Italy that was created during the Diocletianic reforms. It was formed by joining two of the Augustan administrative regions together (Regio VI Umbria and Regio VII Etruria). It was part of the diocese of Italia under Diocletian and, under Constantine I, part of the vicariate of Italia Suburbicaria.
