In the year 1040, von Morsleben became the Bishop of Bamberg. In 1046 he went with King Henry III to Italy and in December, he took part in the Council of Sutri. This took Popes Benedict IX and Sylvester III out of power, and also convinced Pope Gregory VI to resign. King Henry nominated (suggested) Suidger to be the new pope and the council elected him. Suidger took the name Clement II. Shortly after he was elected, Pope Clement and Henry moved to Rome. There, Clement crowned Henry III as Holy Roman Emperor.
