Carloman married a Frankish woman, Gerberga, who according to Pope Stephen III was chosen for him, together with Charlemagne's concubine, Himiltrude, by Pepin the Short. With Gerberga he had two sons, the older of whom was named Pepin after his grandfather, marking him according to Carolingian tradition as the heir of Carloman, and of Pepin the Short. After Carloman's death, Gerberga expected her elder son to become King, and for herself to rule as his regent; however, Carloman's former supporters – his cousin Adalhard, Abbot Fulrad of Saint Denis and Count Warin – turned against her, and invited Charlemagne to annex Carloman's territory, which he duly did. Gerberga then fled (according to Einhard, "for no reason at all") with her sons and Count Autchar, one of Carloman's faithful nobles, to the court of Desiderius, who demanded of the new Pope Hadrian I that he anoint Carloman's sons as Kings of the Franks. Gerberga's flight ultimately precipitated Charlemagne's destruction of the Kingdom of the Lombards; he responded to Desiderius' support of Carloman's children, which threatened Charlemagne's own position, by sweeping into Italy and subjugating it. Desiderius and his family were captured, tonsured, and sent to Frankish religious houses; the fate of Gerberga and her children by Carloman is unknown, although it is possible that they, too, were sent by Charlemagne to monasteries and nunneries.
