Research Notes:

Einhard names "Karlomannum…et Pippinum atque Grifonem" as the three sons of "Karlus maior domus" when recording the latter's death.

He succeeded his father as maior domus jointly with his brother Carloman. They deprived their half-brother Grifo of his inheritance and defeated him after he rebelled against them. In the division of territories agreed with his brother Carloman, Pépin governed Neustria, Burgundy, Provence, Metz and Trier. The brothers were faced with revolts in Frisia, Bavaria, Alemannia and Aquitaine. As a symbolic assertion of their authority, they nominated Childeric III as Merovingian king in 743. In 745, Pépin appropriated the province of Alemannia for himself. The Royal Frankish Annals record that Pepin deposed King Childeric III at Soissons in Nov 751, with approval from Pope Zacharius, and succeeded as PEPIN “le Bref” King of the Franks. He was anointed king at Saint-Denis 28 Jul 754 by Pope Stephen III [II], who had come to France to seek Pépin's help against the Lombards. During his expedition to Italy the following year, Pépin obliged the Lombards to accept the independence of Rome, marking the beginning of the Papal State. He recaptured Narbonne from the Muslim invaders in [759], and finally conquered Aquitaine after the death of Duke Waifar in 768.

The necrology of Prüm records the death "768 VIII Kal Oct" of "Pippinus vir illuster". The necrology of the abbey of Saint-Denis records the death "VIII Kal Oct" of "Pipinus rex". The necrology of Saint-Germain-des-Prés records the death 768 “VIII Kal Oct” of “Pippini regis”. The Annales Metenses record the death "VIII Kal Oct" of "Pippinus" and his burial "in basilica beati Dionysii". His burial place is confirmed by the Annales Laurissenses which record that the body of "domna Berta regina" was transferred to "ecclesia sancti Dionysii martiris" next to her husband. ¹
