Peter Damian, extending the area of his activities, has entered into communication with the Emperor Henry III.

He had been present in Rome when Clement II crowned Henry III and his consort Agnes, and he also attends a synod held at the Lateran in the first days of 1047, in which decrees are passed against simony.

Clement II's short pontificate, starting with the Roman synod of 1047, initiates an improvement in the state of affairs within the Roman Church, particularly by enacting decrees against simony.

A dispute for precedence among the Sees of Ravenna, Milan, and Aquileia is settled in favor of Ravenna.

Clement's election is criticized by the reform party within the papal curia due to the royal involvement and the fact that the new Pope is already bishop of another diocese.

Contrary to later practice, Clement keeps his old see, governing both Rome and Bamberg simultaneously.
