Pope Formosus
Duke Lambert distinguished himself in the wars against the Saracens, but disgraced himself by at Rome in 867; he was afterwards deposed (871), then restored (876), but was a second time excommunicated by Pope John VIII. In 883 Guido II of Spoleto united under his sway the entire dukedom, which from this time was called the Duchy of Spoleto and Camerino. After the death of Charles the Fat (888), Guido had himself crowned Roman Emperor and King of Italy under Pope Stephen V (891); Pope Formosus in 892 also crowned his son Lambert II, who succeeded his father in the dukedom, kingdom, and empire.
