Events

King Liutprand of the Lombards occupies all of the Exarchate of Ravenna. He advances towards Rome along the Via Cassia, and is met at the city of Sutri by Pope Gregory II, near the borders of the Duchy of Rome. Liutprand signs the Donation of Sutri, by which parts of Latium are given to the papacy (the first extension of papal territory in Italy). This marks the historical foundation of the Papal States.
