The Donation of Pepin, or Donation of Pippin, was the transfer of Frankish territory in Central Italy to Pope Stephen II made by Pepin the Short, King of the Franks, in 756. Credited with "effectively establishing the temporal authority of the papacy," the Donation took place amid the Byzantine Empire's decline in Italy and marked both "an important moment in the papal–Carolingian alliance" and an "important step" in the formation of the Papal States. With the fall of Ravenna, the imperial capital in Italy, to Aistulf, King of the Lombards in 751, "any semblance of imperial protection for Rome" had vanished and the pope, who had technically been a Byzantine subject to this point, turned to Pepin for assistance. Pepin invaded Italy and, following an initial victory in 755, he decisively "defeated Aistulf and imposed a peace on him" in 756.
