 Even after Carloman was rechristened "Pepin", Charlemagne maintained the older Pepin at his court, right alongside Charles the Younger, one of Charlemagne's sons by Hildegard.Charlemagne named Charles the Younger "King of the Franks" when he divided his kingdom in 806, and to some historians this suggests that Pepin the Hunchback was also being groomed for future kingship, perhaps for the "lion's share" of Francia, before his rebellion in 792.According to historian Janet Nelson, the rechristening of Carloman probably had more to do with satisfying "political interests outside [Charlemagne's] family," than it did with disinheriting the original Pepin.
