According to the Royal Frankish Annals, Hrodgaud two years later revolted declaring himself a King of the Lombards, whereafter Charlemagne came rushing into Italy where he routed the duke's forces and had him deposed and killed.

In February 828 the last Friulian dux, Baldric, was removed from office by Emperor Louis the Pious at the Imperial diet of Aachen, as he had not been able to defend the Pannonian frontier against the troops of Khan Omurtag of Bulgaria.

The duchy was divided into four counties, which in 846 were gathered together again as part of the Middle Frankish realm ruled by Louis' eldest son Emperor Lothair I.

Berengar paid homage to the East Frankish king Arnulf of Carinthia, he nevertheless lost the crown to Duke Guy III of Spoleto in 889 and did not succeed in recapturing it until 905.

The conflict was settled at the 952 diet of Augsburg, where Berengar II was allowed to retain the royal title as a German vassal, but had to cede Friuli as the March of Verona to Duke Henry I of Bavaria, brother of King Otto I.
