Carloman, d. 754, mayor of the palace in the kingdom of Austrasia after the death (741) of his father, Charles Martel. Ruling with his brother, Pepin the Short, he carried on successful wars against the dukes of Aquitaine, the Saxons, the Swabians, and the Bavarians. The brothers helped St. Boniface reform the Frankish Church, bringing church and state into closer relationship. In 747, Carloman retired to a monastery.
