Lentorama 2025: Perfunctory Popes
Day 26: Leo VIII
This Leo hold a distinction from all the other Leos we've discussed here, in that he served as both an antipope and a pope. And in both instances, his reign was short enough to qualify for inclusion here.
Leo first took the throne in 963, being installed by Holy Roman Emperor Otto I after the emperor deposed the sitting pope, John XII (who had sent Leo as part of delegation to Otto in an attempt to appease him, which clearly didn't go as planned). John still had a strong base of support in Rome, which rebelled and tried to overthrow Leo, only to be put down by Otto's troops. Leo did arrange for those nobles taken prisoner to be released, but when Otto eventually left Rome John's supporters rebelled again, driving Leo out of Rome.
John retook the papacy, and excommunicated Leo, who remained in Otto's court. John would die a few months later, prompting Otto to return to Rome, dethrone John's replacement (Benedict V, who we'll chat about tomorrow), and reinstall Leo as pope.
This time around, Leo was able to hold the throne for nearly a year before he died. His rule was relatively peaceful, though it's believed that a number of bulls attributed to him that gave the Holy Roman Emperor investiture power over popes, bishops, and archbishops were at least tampered with, if not forged outright. This would contribute to what is known as the Investiture Controversy, which took a couple of centuries to straighten out.
The question of how to classify Leo's time in office did linger, with the general consensus being that Leo was an antipope during his first run as pope as John XII did not willingly give up the papacy. Where Benedict did give up the papacy (albeit under some sort of duress), and no one else tried to restore him (or claim the throne for themselves), Leo can be considered pope during his second run.
