Around 670, Pippin II married Plectrude for her inheritance of substantial estates in the Moselle region. They produced at least two children and through them at least two significant grandchildren. These legitimate children and grandchildren claimed themselves to be Pepin's true successors and with the help of his widow Plectrude tried to maintain the position of Mayor of the Palace after Pepin II's death on December 16, 714. However, Charles Martel, Pippin's son by his mistress, Alpaida (or Chalpaida), had gained favour among the Austrasians, primarily for his military prowess and ability to keep them well supplied with booty from his conquests. Despite the efforts of Plectrude to silence her rival's child by imprisoning him, he became the sole Mayor of the Palace and de facto ruler of Francia.
