king of Italy (781–810) and second son of the Frankish emperor Charlemagne by Hildegard.

Given the title of king of Italy in 781, Pippin (originally named Carloman) took part in campaigns against Duke Tassilo III of Bavaria from 787 and led an army against the Avars in 796. His Venetian campaign (809–810) enabled Charlemagne later to come to favourable terms with the Byzantine Empire. As early as 806, Charlemagne, in planning the division of his lands, had decided that on his death Pippin should inherit Italy, Bavaria, and the southern territory of the Alemanni, but Pippin predeceased his father by four years.
