Etruscan era
The ancient city (urbs vetus in Latin, whence "Orvieto"), populated since Etruscan times, has usually been associated with Etruscan Velzna, but some modern scholars differ. Orvieto was certainly a major centre of Etruscan civilization; the archaeological museum (Museo Claudio Faina e Museo Civico) houses some of the Etruscan artefacts that have been recovered in the immediate neighbourhood.

Middle Ages
Orvieto, sitting on its impregnable rock controlling the road between Florence and Rome where it crossed the Chiana, was a large town: its population numbered about 30,000 at the end of the 13th century. Its municipal institutions already recognized in a papal bull of 1157, from 1201 Orvieto governed itself through a podestà , who was as often as not the bishop, however, acting in concert with a military governor, the "captain of the people". In the 13th century bitter feuds divided the city, which was at the apogée of its
