Schism within the Curia: The Twin Papal Elections of 1378

The Great Western Schism divided Latin Christendom along national lines, but it began in 1378 not as a conflict between two national factions of cardinals in the conclave, but in two successive elections by the same college of cardinals, none dissenting. Each of the two new popes had the same usual claim to canonical legitimacy, but since each election was flawed in its circumstances and procedure, each pope could and did condemn and excommunicate his rival. Investigating the activities of the two leading bureaucrats of the Roman Curia, the archbishops who headed its two most powerful ministries, the Chancery and Camera, this paper explores an alternative interpretation of the two elections. According to this narrative, there were two extraordinary interventions in the succession to Pope Gregory xi: the disorderly papal election of 9 April 1378 was captured by one papal minister, the deputy director of the papal Chancery, Bartolomeo Prignano, archbishop of Bari; the second election, of 20 September, which began the Great Western Schism, was a counter-coup managed by the minister in charge of the Camera Apostolica, the chamberlain Pierre de Cros, archbishop of Arles.
