Charles was obliged to continue it alone, which he did with complete success.

At the end of this first campaign, Pepin's widow, the Queen-mother Bertha, reconciled her two sons; but an unexpected incident, the death of Carloman two years afterwards in 771, re-established unity more surely than the reconciliation had re-established harmony.

For, although Carloman left sons, the grandees of his dominions, whether laic or ecclesiastical, assembled at Corbeny, between Laon and Rheims, and proclaimed in his stead his brother Charles, who thus became sole king of the Gallo-Franco-Germanic monarchy.

And as ambition and manners had become less tinged with ferocity than they had been under the Merovingians, the sons of Carloman were not killed or shorn or even shut up in a monastery: they retired with their mother, Gerberge, to the court of Didier, king of the Lombards.

"King Charles," says Eginhard, "took their departure patiently, regarding it as of no importance." Thus commenced the reign of Charlemagne.
The original and dominant characteristic of the hero of this reign, that which won for him, and keeps for him after more than ten centuries, the name of Great, is the striking variety of his ambition, his faculties, and his deeds.
