Формоз
In 893 the new Pope Formosus, not trusting the newly crowned co-emperors Guy III of Spoleto and his son Lambert II of Spoleto, sent an embassy to Omuntesberch, where Arnulf was meeting with Svatopluk I of Moravia, to request that Arnulf come and liberate Italy, where he would be crowned emperor in Rome. Arnulf met the "Primores" of the Kingdom of Italy, dismissed them with gifts and promised to assist the pope. Arnulf then sent his son Zwentibold with a Bavarian army to join Berengar of Friuli. They defeated Guy, but were bought off and left in autumn.
