About Leo III

Pope Leo III

Pope Leo III served as bishop of Rome and ruler of the Papal States from December 26, 795, until his death on June 12, 816. His pontificate is primarily defined by his pivotal role in crowning Charlemagne as emperor on Christmas Day, 800. This significant event, though not approved by most in Constantinople, was a key moment in strengthening the alliance between the papacy and the burgeoning Carolingian empire, altering the political landscape of Western Europe.

Life and Pontificate

Details about Leo III's origins suggest he was of Roman nation, with his father's name, Atzuppius, possibly indicating an Arab background. He seemingly knew Greek and had served as cardinal-priest of Santa Susanna and vestiarius under Pope Adrian I. His election in 795 was swift, occurring the day Adrian I was buried, possibly to preempt Frankish interference. Leo immediately sought Charlemagne's protection, sending him keys and the city's standard, signifying his view of the Frankish king as protector of the Holy See.

Leo's pontificate was not without peril. In 799, he was attacked by supporters of Adrian I, who sought to depose him on charges of adultery and perjury. He was injured but rescued by Charlemagne's emissaries and later sought refuge with Charlemagne. After Charlemagne intervened, Leo took an oath of purgation in December 800, clearing his name, and his opponents were exiled.

Major Contributions and Policies

The coronation of Charlemagne as emperor on Christmas Day, 800, remains Leo III's most historically significant act. This event, occurring while the imperial throne in Constantinople was occupied by Irene of Athens, re-established an imperial title in the West and symbolized a new political order. While the Byzantines were offended, they were too occupied with their own defenses to offer significant opposition.

In ecclesiastical matters, Leo III supported the Western theological doctrine that the Holy Spirit proceeds from both the Father and the Son, placing two silver shields with the unadulterated creed in both Greek and Latin at St. Peter's entrance as a safeguard for the orthodox faith. He also intervened in English church affairs, restoring King Eardwulf of Northumbria and settling disputes between the archbishops of York and Canterbury. He reversed Pope Adrian I's decision regarding the pallium for Bishop Hygeberht of Lichfield, believing the English episcopate had been misrepresented.

Legacy

Pope Leo III died in 816 after a reign of over twenty years. He was canonized and his name was entered into the Roman Martyrology in 1673 by Pope Clement X. His legacy is intrinsically tied to the imperial coronation of Charlemagne, an event that profoundly shaped the relationship between the Church and state in the medieval period and beyond.
