Juan X
In 922, when Seulf became Archbishop of Rheims, in an effort to appease Herbert II Seulf solemnly promised him he could nominate his successor. In 923, Count Herbert took the bold step of imprisoning King Charles III, who died still a captive in 929. Then, on the death of Seulf in 925, with the help of King Rudolph, he acquired for his second son Hugh (then five years old) the archbishopric of Rheims. Herbert took the additional step of sending emissaries to Rome to Pope John X to gain his approval, which that pope gave in 926. On his election young Hugh was sent to Auxerre to study.
