Pope Gelasius II

Pope Gelasius II (c. 1060/1064 – 29 January 1119), 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.
