The Pippinids or Arnulfings are the members of a family of Frankish nobles in the Pippinid dynasty. Their selections served as Mayor of the Palace, de facto rulers, of the Frankish kingdoms of Neustria and Austrasia that were nominally ruled by the Merovingians.
His son Ansegisel married Saint Begga, the daughter of Pepin of Landen, and their son was Pepin of Heristal. It is from Pepin's grandfathers that the dynasty receives its earlier (pre-Martel) names: Arnulfing or Pippinid.
The mayoralty of the palace of the kingdom of Austrasia began in the family with Ansegisel and continued with Pepin of Heristal. Pepin conquered Neustria at the Battle of Tertry in 687 and spread Arnulfing authority over all the Franks.
The dynasty formally ended with the death of Pepin, who was succeeded by his son, Charles Martel. Charles was the son of Pippin (there were multiple spellings of his name) and his second wife, Alpaida. After his death, the first wife of Pepin (Plectrude) had Charles imprisoned so they would not compete with her choice for heir (their grandson, Theudould).
