Liber Historiae Francorum
Childebert III (or IV), called the Just () (c.678/679 – 23 April 711), was the son of Theuderic III and Clotilda (or Doda) and sole king of the Franks (694–711). He was seemingly but a puppet of the mayor of the palace, Pepin of Heristal, though his "placita" show him making judicial decisions of his own will, even against the Arnulfing clan. His nickname has no comprehensible justification except possibly as a result of these judgements, but the "Liber Historiae Francorum" calls him a "famous man" and "the glorious lord of good memory, Childebert, the just king."
