Biography
Leo III became pope in 795 and faced serious opposition from members of the Roman nobility. A violent attack during a procession formed part of those conflicts. He sought assistance from Charlemagne, whose relationship with Rome became a major element of the political circumstances surrounding his pontificate.
Leo crowned Charlemagne emperor and also took positions in disputes about the language used in the creed. He resisted inserting the Filioque into the text then recited at Rome, despite its use elsewhere in the West. He died in 816, after a pontificate in which diplomacy and doctrinal questions were closely entangled with Roman political conflict.
