Pope Sergius IV was the bishop of Rome and nominal ruler of the Papal States from 31 July 1009 to his death. His temporal power was eclipsed by the patrician John Crescentius. Sergius IV may have called for the expulsion of Muslims from the Holy Land, but this is disputed. Since his time, the practice that the person who has been elected to the office of pope takes on a new name became a tradition.

The Diocese of Albano is a Latin suburbicarian see of the Diocese of Rome in Italy, comprising seven towns in the Province of Rome. Albano Laziale is situated on the Appian Way some 15 kilometers from Rome.
