711 Childebert III 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." He had a son named Dagobert, who succeeded him, as Dagobert III but his wife was not Edonne, the invention of later fantasists. It is possible, though not likely, that Chlothar IV was also his son. He spent almost his entire life in a royal villa on the Oise
725 Wihtred of Kent king of Kent from about 690 or 691 until his death. He was a son of Ecgberht I and a brother of Eadric. Wihtred acceded to the throne after a confused period in the 680s, which included a brief conquest of Kent by Cædwalla of Wessex and subsequent dynastic conflicts. His immediate predecessor was Oswine of Kent, who was probably descended from Eadbald of Kent, though not through the same line as Wihtred. Shortly after the start of his reign, Wihtred issued a code of laws—the Law of Wihtred—that has been preserved in a manuscript known as the Textus Roffensis. The laws pay a great deal of attention to the rights of the Church, including punishment for irregular marriages and for pagan worship.
