Clovis II

Clovis II (633 – 657) was King of the Franks in Neustria and Burgundy, having succeeded his father Dagobert I in 639. His brother Sigebert III had been King of Austrasia since 634. He was initially under the regency of his mother Nanthild until her death in her early thirties in 642. Nanthild's death allowed Clovis to fall under the influence of the secular magnates, who reduced the royal power in their own favour; first Aega and then Erchinoald. The Burgundian mayor of the palace Flaochad used him to lure his rival, Willebad, to a battle in Autun, in which Willebad was killed.
