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.
