Pope Boniface VI had the second shortest Papacy in history and he’s also kind of technically sorta not a valid Pope according to Pope John IX. Boniface had a checkered history with the Church. When he was a young priest he was defrocked twice(twice!?!)due to immoral behavior. Whatever this behavior was,it’s not known to us. When Pope Formosus died,it was rumored that Holy emperor Arnulf would impose a Pope of his choosing on Rome and this caused the Romans to completely freak out and start rioting…..even though Romans never needed a good excuse to riot since they were inherently a “rioty” people anyway. In all of the confusion Deacon Boniface was somehow elected to the Papacy. This violated Canon Law that stated that it was illegal to elect a non-priest to the Papacy. By the time anyone noticed this mistake,Pope Boniface VI was all but dead only 15 days later. Whether this was by the “extreme gout” that he was said to suffer from,or if it was murder,it is not known. In 898 Pope John IX declared the election of Boniface invalid however he’s still counted among the Popes to this day.
