Following the Horse Plague, the central authority of the Catholic Church virtually collapsed. The chaos and death in Rome rivaled that of Istanbul and Milan, and, when the dust settled, the Pope and many clergy were dead. Because of the general chaos, records have not been preserved that exactly pinpoint his death, though it is known that Pope Silvester IV was elected in July of 1516, which implies that Julius II’s death occurred shortly before. Several theories have been proposed to explain the death of Pope Julius II. Usually, death by plague is dismissed as unlikely, because of the seclusion afforded by the Papal Palace. However, it is not impossible that he fell victim to the plague much in the same way as the royal family of Castile-Aragon, who were similarly sequestered.
It is also possible that Julius II was the subject of political assassination. Conspiracy theorists point to the fact that he was the last non-French pope for almost 130 years as possible evidence for foul play. However, this is hardly damning evidence, despite the steady shift of the Catholic center of gravity to Northern France following the Horse Plague, which culminated in the permanent relocation of the Papacy to Bourges in 1569. For the French King Louis XII to risk so much in order to gain a more firm control of the Papacy seems extremely unlikely, however this theory has been a favorite of conspiracy theorists for hundreds of years, and so is important to mention.
It is far more possible that Julius II simply perished in the fires that devastated Rome following the peasant revolt of 1514, and which burned intermittently until 1516. Known as the
Arsoni, a group of individuals believed to be composed of peasants staged fires and riots across central Italy in the years between 1514 and 1516. Though believed to have been at first simply a demonstration of anger, the
Arsoni began to set fires with the express purpose of looting during the distraction. Many priceless works of art and historical artifacts were lost during this period, The Lateran Palace, the historical living quarters of the Popes in Rome, was burned at least twice. It is easily possible that Julius II was killed by one of these fires, or by the riots that undoubtedly followed.
Though the true cause of the death of Pope Julius II will never be known, its affects are unmistakable. His death marked the last Pope who would permanently live in Rome without a rival Antipope elsewhere in Europe, and, some say, the beginning of the Reformation. Though the first true battles of the Reformist Wars were still years away at this time, the abandonment of Rome by the Popes caused great despair in the plague-affected regions amongst peasant and priest alike. The desire for change and recognition that inspired the
Arsoni to start the first fires of 1514 was the same desire that inspired Marinus of Pisa to symbolically invert the Papal Cross in 1531, starting the Reformation outright.
