Although Berengar had the support of the major Roman nobility and the pope, he had enemies elsewhere. In 923, a combination of the Italian princes brought about the defeat of Berengar, again frustrating the hopes of a united Italy, followed by his assassination in 924. Then in 925 Theophylact of Tusculum and Alberic I of Spoleto also died; this meant that within the course of a year, three of Pope John’s key supporters had died, leaving John dangerously exposed to the ambitions of Theophylact’s daughter, Marozia, who, it was said, resented John’s alleged affair with her mother, Theodora.
