Question: Information:  - Vatican City , officially Vatican City State or the State of Vatican City, is a walled enclave within the city of Rome. With an area of approximately 44 hectares (110 acres), and a population of 842, it is the smallest State in the world by both area and population, but formally it is not sovereign, sovereignty being held by the Holy See, the only entity of public international law that has diplomatic relations with almost every country in the world.  - Pope John X (died c. June 928) was Pope from March 914 to his death in 928. A candidate of the Counts of Tusculum, he attempted to unify Italy under the leadership of Berengar of Friuli, and was instrumental in the defeat of the Saracens at the Battle of Garigliano. He eventually fell out with Marozia, who had him deposed, imprisoned, and finally murdered.

At the wedding of his mother to King Hugh of Italy , Alberic and his new stepfather quarreled violently after Hugh slapped Alberic for clumsiness . Infuriated by this and perhaps motivated by rumors that Hugh intended to have him blinded , Alberic left the festivities and incited a Roman mob to revolt against Hugh . In December 932 Hugh fled the city , Marozia was cast into prison , and Alberic took control of Rome . In 936 Alberic married his stepsister Alda , the daughter of King Hugh , and had a son with her , Octavian .
