List of Famous people named Gelasius

Pope Gelasius I was the bishop of Rome from 1 March AD 492 to his death on 19 November 496. He was probably the third and final bishop of Rome of Berber descent. Gelasius was a prolific author whose style placed him on the cusp between Late Antiquity and the Early Middle Ages. His predecessor Felix III employed him especially in drafting papal documents. During his pontificate he called for strict Catholic orthodoxy, more assertively demanded obedience to papal authority, and, consequently, increased the tension between the Western and Eastern Churches.

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.
