Childebert the Adopted
Frankish king
Childebert III the Adopted (Childebertus Adoptivus) was a Frankish king.
Childebert was a son of the Mayor of the Palace Grimoald the Elder. He was thus a grandson of Pepin of Landen.
He was adopted by King Sigebert III and Queen Chimnechild.
When Sigebert III died in 656, Grimoald had Sigebert’s biological son Dagobert II tonsured and sent him to an Irish monastery and then proclaimed Childebert king of Austrasia.
Grimoald, Childebert and Ansegisel (who had married the daughter of Pepin of Landen) were finally seized and turned over to the king of Neustria, Clovis II, who had them killed. There are two differing accounts of his death, however. Either Clovis and his mayor of the palace, Erchinoald, captured and executed him in 657 or Chlothar III annexed Austrasia in 661, deposing the young usurper and executing them both the next year.
The family reappeared in politics with the rise of Ansegisel’s son, Pepin of Herstal.
This brief starts where responsible research should: with the source description of “Childebert the Adopted” as frankish king. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the people & ideas register because the source frames it as frankish king. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Biographical claims are most persuasive when dates, appointments and relationships can be traced to records created close to the events described. The source revision retrieved here is dated Sep 11, 2026. The linked authority identifier is Q304688.
A concise life account rarely captures disputed attribution, private networks or the changing language used to describe a career. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
