Honorius III and the Crusade: Responsive Papal Government Versus the Memory of his Predecessors

The medieval papacy was an institution steeped in its own history and traditions, but how far did the popes’ recollection of their predecessors’ ‘blessed memory’ influence their own political decision-making? Through access to earlier letter registers, combined with their memories of experiences at the curia before election to the papal throne, popes could potentially delve into their own institutional history when making contemporary political decisions. In 1977 James Powell suggested that, in negotiations with Emperor Frederick II (1220–50) over his Holy Land crusade vow, Pope Honorius III (1216–27) had reached decisions based on his memory of the negotiations between Pope Clement III (1187–91) and Frederick II’s grandfather, Emperor Frederick I (1155–90).
