Pope Stephen II
Born in Brescia, Desiderius was originally a royal officer, the "dux" of Tuscia and he became king after the death of Aistulf in 756. At that time, Aistulf's predecessor, Ratchis, left his monastic retreat of Montecassino and tried to seize the kingdom, but Desiderius put his revolt down quickly with the support of Pope Stephen II. At his coronation, Desiderius promised to restore many lost papal towns to the Holy See and even enlarge the Papal State.
