Drogo (born c. 730) was a Frankish nobleman of the Pippinid family and the eldest son of Carloman, mayor of the palace of Austrasia under the Merovingian king Childeric III.
Around October that year,[1] his father abdicated his mayoralty, went on a pilgrimage to Rome and entered the monastery of Monte Cassino.
They sought to create a simplified Pippinid family tree so as to make the position of Pippin III, founder of the Carolingian dynasty, appear stronger than it was.
[6] The Chronicle of Fredegar claims, misleadingly, that Carloman entrusted both Austrasia and Drogo to Pippin's care.
[3] The letter writer asks a certain Andhemus "whether he [Boniface] has gone to the synod of the duke of the western provinces [Pippin] or to the son of Carloman [Drogo].
Historian Roger Collins notes that "given a choice in 747 between Pippin and his nephew, for Boniface to favour the already proven western ruler over the young and inexperienced eastern one [made] pragmatic sense.
[10][11] The birth of a son, Charles, to his uncle on 2 April 748 seems to have fundamentally altered the relationship between Drogo and Pippin.
