Mayor of the Palace
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.
