Drawing of the later effigy of Carloman I — Charles Fichot, 1848
A King, Not a Preliminary Chapter
In 768, there were two new kings of the Franks. Charlemagne and Carloman each received a share of their father’s kingdom and each had an independent position from which to act. The familiar story of Charlemagne’s rise can make Carloman seem like an interruption before the proper reign begins. That perspective belongs to the eventual outcome, not to the situation the brothers inherited.
Carloman was born in 751 and died in December 771. Those twenty years encompass a transition from a family possessing effective power to a family possessing kingship. His own royal career lasted only a little over three years. The brevity helps explain the thin record, but the record is also thin because the people who preserved it had reasons to center his brother.
The Inheritance of a New Dynasty
His father, Pepin the Short, had displaced the Merovingian dynasty and reinforced the new kingship through papal sanction. Carloman grew up within that newly authorized royal household. His mother, Bertrada, remained an important participant in family diplomacy after Pepin’s death. The dynasty’s position was powerful, but its arrangements still depended on aristocratic acceptance and cooperation.
Dividing rule between sons was not an inexplicable mistake in an otherwise modern system of government. Frankish kingship had a history of shared and divided inheritances. Each son could possess a recognized claim, his own supporters, and responsibilities within a portion of the realm. The potential for conflict followed from those arrangements, but conflict was not the only possible result.
The Royal Frankish Annals record separate royal elevations in 768, associating Charlemagne with Noyon and Carloman with Soissons. These concrete acts establish Carloman as a ruler in his own right. His kingdom was not a governorship that Charlemagne graciously delegated. Treating the arrangement seriously changes how later accusations of unhelpfulness or jealousy should be assessed.
Cooperation Seen from One Side
The Aquitanian campaign of 769 provides a revealing episode. The annals describe a meeting between the brothers and Carloman’s return home while Charlemagne continued the operation. Einhard later presents the younger brother as withholding promised assistance. The outline suggests difficulty in cooperation; the interpretation of motives comes from a writer devoted to Charlemagne’s memory.
Einhard also explains tension through the machinations of Carloman’s supporters, while praising Charlemagne’s patience. This distribution of blame is convenient for a biography of the surviving king. It separates the admirable ruler from family conflict by making his brother’s circle responsible. It may preserve genuine friction, but it cannot be accepted as an impartial reconstruction of how both courts understood their interests.
An independent Carloman could have viewed military commitments, territorial ambitions, and relations with neighboring powers differently. That possibility does not establish a hidden program, nor does it prove that his decisions were wiser. It simply restores the alternatives that a victorious narrative tends to close. We do not possess Carloman’s explanation of the meeting or a comparable biography composed for his household.
The Mother’s Diplomacy and the Brother’s Death
Bertrada’s journey through Bavaria into Italy in 770 belongs to a wider effort to manage relations around the royal family. Charlemagne’s marriage to a daughter of the Lombard king Desiderius was one result of this diplomacy. Carloman’s position within the family made such arrangements relevant to him even when the evidence does not establish his own contribution to every negotiation.
His death at Samoussy in 771 transformed the balance. Important ecclesiastical and aristocratic figures from his kingdom approached Charlemagne, who took over the inheritance. Carloman’s widow, Gerberga, instead went to Italy with their sons and a smaller group of supporters. They sought the protection of Desiderius. The contrast between those movements reveals a contested dynastic situation more clearly than claims of effortless unanimity do.
Einhard calls the widow’s flight unreasonable. Yet a mother whose children’s royal future had become precarious had intelligible grounds for seeking another protector. That does not prove what she feared would happen. It does show why the biographer’s dismissal should not be mistaken for an adequate account of her situation. Her action preserved the possibility of claims the surviving king had reason to extinguish.
What the Silence Cannot Tell Us
Carloman’s children later became part of the conflict between the Lombard king and Charlemagne. Papal accounts allege an effort to have them anointed as Frankish rulers. Their presence at another court therefore mattered after their father’s death. The subsequent fate of the family remains obscure, and obscurity should not be filled with a confident story of murder or rescue.
Carloman likewise remains untyped. Royal office, a strained relationship with an elder brother, and a reported refusal to assist one campaign do not distinguish a stable personality pattern. The available testimony has too much at stake in assigning fault. Leaving him without a type recognizes the difference between an identifiable political participant and a psychologically recoverable individual.
