Pope Callixtus II

Calixtus II, actually Guido of Burgundy or Guido of Vienne (c. 1060 in Quingey, † December 13, 1124 in Rome), was Pope from 1119.

He was a younger son of Count William I of Burgundy. Like his brother, Hugo († November 13, 1101 ), which was in 1086 Archbishop of Besancon, he embarked on a clerical career and became archbishop of Vienne in 1088, the territory was part of the Holy Roman Empire. For the secular dominion over the lands of his archdiocese, he was so far vassal of the Holy Roman Emperor Henry V.

After the death of Pope Gelasius II was elected on February 2, 1119 Pope and took the name of Calixtus II. In April 1121, he managed to arrest the anti-pope Gregory VIII in Sutri, settle and incarcerated.

On September 23, 1122, he also laid the investiture conflict with Emperor Henry V at by the Concordat of Worms. The Emperor accepted the claim of the church on the right, bishops and abbots itself to select and appoint (so-called investiture ). The Pope accepted in return that the choice of the German bishops and abbots had to negotiate in the presence of imperial deputy, and that the person elected should receive his worldly sovereignty only by subsequent investiture by the emperor.

1120 he spoke of David Menevia and 1123 Conrad of Constance sacred. He died in 1124 in Rome and was buried in the Lateran Basilica.
