Peredeo was a Lombard duke of Vicenza, who was killed by the Venetians in Ravenna, which the Lombards had shortly taken, sometimes between 726 and 741.
In the 730s or early 740s, Hildeprand, nephew of king Liutprand, and Peredeo, duke of Vicenza, managed to take Ravenna, the capital of the Exarchate of Ravenna.
The events around the demise of the Exarchate of Ravenna only involved the Venetians marginally. It is nevertheless important to the history of Venice.
