He began his career as the regent during
Theuderic II's minority (596 – c. 604). In 612, when Theuderic became king of Austrasia, he became mayor of the palace. Following Theuderic II's death in 613, he helped
Queen Brunhilda secure the accession of the young King
Sigebert II, but soon defected to King
Clotaire II of
Neustria after discovering a plot to kill him, thus betraying Brunhilda into Clotaire's hands. Therefore, when Clotaire then became sole
king of the Franks, he left Warnachar as the mayor of the palace of Burgundy and swore that he should never be deposed from this office during his lifetime. He held this position for over a decade, until he died in 626 (or 627 or 628, when he is said to have called a synod of Burgundian bishops). His son,
Godinus, succeeded him. ==References==
