Esteban II
It has been suggested that an early draft of the "Donation of Constantine" was made shortly after the middle of the 8th century, in order to assist Pope Stephen II in his negotiations with Pepin the Short, who then held the position of Mayor of the Palace (i.e., the manager of the household of the Frankish king). In 754, Pope Stephen II crossed the Alps to anoint Pepin king, thereby enabling the Carolingian family to supplant the old Merovingian royal line. In return for Stephen's support, Pepin gave the pope the lands in Italy which the Lombards had taken from the Byzantine (Eastern Roman) Empire. It is also possible it originated in the chancery of Stephen's immediate successor Paul I. These lands would become the Papal States and would be the basis of the papacy's temporal power for the next eleven centuries.
