The Duke of Spoleto was the ruler of Spoleto and most of central Italy outside the Papal States during the Early and High Middle Ages (c. 500 – 1300). The first dukes were appointed by the Lombard king, but they were independent in practice. The Carolingian conquerors of the Lombards continued to appoint dukes as did their successor to the Holy Roman Empire. In the 12th century, the dukes of Spoleto were far and away the most important imperial vassals in Italy.
They usually bore the title dux et marchio, "duke and margrave" as rulers of both Spoleto and Camerino.
