Pope Leo III (died 12 June 816) was bishop of Rome and ruler of the Papal States from 26 December 795 to his death. Protected by Charlemagne from the supporters of his predecessor, Adrian I, Leo subsequently strengthened Charlemagne's position by crowning him emperor. The coronation was not approved by most people in Constantinople, although the Byzantines, occupied with their own defenses, were in no position to offer much opposition to it. Rise According to the Liber Pontificalis, Leo was "of the Roman nation, the son of Atzuppius" (natione romanus ex patre Atzuppio). The Chronicon Anianense says, more specifically, that he was "born in Rome to Asupius and Elizabeth" (natus rome ex patre asupio matre helisabeth). Usually considered to be of Greek origin, his father's name may suggest an Arab background. An earlier person of the same name or nickname, Atzypios, was an iconoclast adversary of John of Damascus.

This he did to show that he regarded the Frankish king as the protector of the Holy See. In return, Charlemagne sent letters of congratulation and a great part of the treasure which the king had captured from the Avars. Pontificate Charlemagne's gift enabled Leo to be a great benefactor to the churches and charitable institutions of Rome. While Charlemagne's letter is respectful and even affectionate, it also exhibits his concept of the coordination of the spiritual and temporal powers, and he does not hesitate to remind the pope of his grave spiritual obligations. Attack on Leo in 799 Prompted by jealousy, ambition, or the thought that only someone of the nobility should hold the office of pope, a number of relatives of Adrian I formed a plot to render Leo unfit to hold his office.
