He was also Margrave of Camerino, and the son-in-law of Theophylact I, Count of Tusculum, the most powerful man in Rome.
He may have later been the count of Fermo, but whatever the case, he succeeded to Spoleto after murdering Duke Guy IV.
Theophylact, Count of Tusculum, in the Alban Hills southeast of Rome served as palatine iudex (or leader of the militia)[2] for Emperor Louis III.
He remained in Rome, commanding a group of soldiers after the emperor's return to Provence in 902, and was prominent in the overthrow of Antipope Christopher in January 904.
This alliance with the Tusculani was very advantageous, and he received the title of "patrician of the Romans," patricius Romanorum.
