宮宰
Pepin's father Charles Martel died in 741. He divided the rule of the Frankish kingdom between Pepin and his elder brother, Carloman, his surviving sons by his first wife: Carloman became Mayor of the Palace of Austrasia, Pepin became Mayor of the Palace of Neustria. Grifo, Charles's son by his second wife, Swanahild (also known as Swanhilde), demanded a share in the inheritance, but he was besieged in Laon, forced to surrender and imprisoned in a monastery by his two half-brothers.
