"Charibert II (607/617–8 April 632), a son of Clotaire II and his junior wife Sichilde, was briefly King of Aquitaine from 629 to his death, with ...
his capital at Toulouse. We have no direct statement about when Charibert was born exactly, only that he was "a few years younger" than his half-brother Dagobert. His father Clotaire evidently had a bigamous marriage (not then uncommon) and he was the offspring of the junior wife.
When his father, Clotaire II, King of the Franks, died in 629, Charibert made a bid for the kingdom of Neustria against his elder half-brother Dagobert I, who had already been king of Austrasia since 623. In the ensuing negotiations, Charibert, a minor, was represented by his uncle Brodulf, the brother of Queen Sichilde. Dagobert had Brodulf killed, but did not intercede when his half-brother took over the near-independent realm of Aquitaine. Apparently this caused no disagreement, as in 631 Charibert stood godfather to Dagobert´s son Sigebert." - (en.wikipedia.org 18.05.2020)
