Lamberto Scannabecchi was elected pope, taking the name Honorius II.

The 1124 papal election took place after the death of Pope Callixtus II on 13 December 1124. The election was characterised by a power struggle between Italian cardinals supported by the Pierleoni family and northern cardinals supported by the Frangipani family. On 16 December the cardinals elected Theobaldo Boccapecci, the cardinal-priest of Sant'Anastasia. He chose the name Celestine II. Before his consecration, however, an armed party of the Frangipani attacked and wounded the newly elected pope. In the following confusion the Bishop of Ostia Lamberto Scannabecchi, the Frangipani's candidate was proclaimed pope under the name Honorius II. After several days of factional fighting Celestine was abandoned by his supporters. However, Honorius would not accept the throne in this manner and resigned as well. He was immediately re-elected and consecrated on 21 December 1124.

Pope Honorius II, born Lamberto Scannabecchi, was head of the Catholic Church and ruler of the Papal States from 21 December 1124 to his death in 1130.
