Childebert II
Columbanus was also involved in a dispute with members of the Frankish royal family. Upon the death of King Gontram of Burgundy, the succession passed to his nephew, Childebert II, the son of his brother Sigebert and Sigebert's wife Brunhilda of Austrasia. When Childebert II died, he left two sons, Theuderic II who inherited the Kingdom of Burgundy, and Theudebert II who inherited the Kingdom of Austrasia. As both were minors, Brunhilda, their grandmother, declared herself their guardian and controlled the governments of the two kingdoms.
