Pope Callistus II
Also written Calixtus II.
Son of Count William of Burgundy.
Reigned from 1119 to 1124.
Born in Quingey, France as Gumo; died Rome, Italy.
He was a Benedictine, Archbishop of Vienne, and cardinal.
As pope he disciplined the French clergy, decreed against investiture, simony, and concubinage of the clergy.
The question of investiture between him and Emporer Henry V was settled by the Concordat of Worms, 1122, and confirmed by the First Lateran Council, 1123.
He regained a portion of the diminished Patrimony of Saint Peter, and beautified Rome.
