The Pippinids and the Arnulfings were two Frankish aristocratic families from Austrasia during the Merovingian period. They dominated the office of mayor of the palace after 687 and eventually supplanted the Merovingians as kings in 751, founding the Carolingian dynasty.
The names "Pippinid" and "Arnulfing" are modern conventions, reflecting the families' descent from two contemporaries, Arnulf of Metz (died c. 640) and Pippin of Landen (died 640). The recurrence of the leading name Pippin in the family led the anonymous author of the Annals of Metz (c. 805) to call the family Pippinios, the earliest known designation for the family. In a strict sense, the Pippinids are the descendants of Pippin of Landen and the Arnulfings those of Arnulf of Metz. These groups only overlap via the marriage of Arnulf's son Ansegisel and Pippin's daughter Begga and their son, Pippin of Herstal and his descendants.
