Pope Nicholas III

Born around 1225 into Roman nobility, Giovanni Gaetano Orsini spent decades moving through the papal machinery: Cardinal-Deacon under Innocent IV, protector of the Franciscans under Alexander IV, inquisitor-general under Urban IV. After a six-month vacancy following John XXI's death in 1277, family influence secured his election in November. He ruled the Papal States for less than three years, dying on 22 August 1280. What followed shaped his afterlife more than his reign: Dante placed him in the Inferno's eighth circle, buried upside-down among the simoniacs, and that poetic sentence became his enduring reputation.
