CARLOMAN (d. 754)  , mayor of the palace under the Merovingian kings, was a son of Charles Martel, and, together with his brother, Pippin the Short, became mayor on his father's death in 741, administering the eastern part of the Frankish kingdom . He was successful in extending the power of the Franks in various wars with his troublesome neighbours, and was not less zealous in seeking to strengthen and reform the church in the lands under his rule . In 747 Carloman laid down his office and retired to a monastery which he founded on Monte Soracte, but troubled by the number of his visitors, he subsequently entered a monastery on Monte Casino .
