Pope Gelasius II, born Giovanni Caetani or Giovanni da Gaeta, was head of the Catholic Church and ruler of the Papal States from 24 January 1118 to his death in 1119. A monk of Monte Cassino and chancellor of Pope Paschal II, Caetani was unanimously elected to succeed him. In doing so, he also inherited the conflict with Emperor Henry V over investiture. Gelasius spent a good part of his brief papacy in exile.

Pope Paschal II, born Ranierius, was head of the Catholic Church and ruler of the Papal States from 13 August 1099 to his death in 1118. A monk of the Abbey of Cluny, he was created the cardinal-priest of San Clemente by Pope Gregory VII (1073–85) in 1073. He was consecrated as pope in succession to Pope Urban II (1088–99) on 19 August 1099. His reign of almost twenty years was exceptionally long for a medieval pope.
