Theobald of Bavaria

Machine translation, like DeepL or Google Translate, is a useful starting point for translations, but translators must follow the LLM translation guideline, revise errors as necessary and confirm that the translation is accurate, rather than simply copy-pasting machine-translated text into the English Wikipedia. Do not translate text that appears unreliable or low-quality. If possible, verify the text with references provided in the foreign-language article. You must provide copyright attribution in the edit summary accompanying your translation by providing an interlanguage link to the source of your translation. A model attribution edit summary is Content in this edit is translated from the existing German Wikipedia article at [[:de:Theudebald (Bayern)]]; see its history for attribution. You may also add the template {{Translated|de|Theudebald (Bayern)}} to the talk page. For more guidance, see Wikipedia:Translation. |

Theobald (also Theudebald, Theodolt, or Theodoalt) (died 717/719) was the duke of Bavaria from at least 711, when his father Theodo associated him with his rule at Passau or Salzburg. He was the second son of Theodo and Folchaid.

His father divided the duchy between his four sons some time before 715. On his death in 716, the duchy was divided, but it is not certain whether this division was territorial or not. If so, it seems likely, from references to wars with the Thuringii, that Theobald had his capital at Ratisbon and his dukedom corresponded to that diocese.

Theobald's name occurs commonly in the "Codex of Salzburg" (Salzburger Verbrüderungsbuch) of 784.

Theobald married Biltrude as his first or second wife. He may have had a prior marriage to one Waldrada, who conversely may have been his younger brother Tassilo's wife. Biltrude later married Grimoald, his youngest brother and successor.
