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 wa
s 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.
