THEODO V Duke of Bavaria. The mid-13th century Series Ducum Bavariæ lists, in order, the dukes from 514 as Theodo "dux primus"…Theodebertus, Theodo IV "qui cum filiis sanctum Corbiniacum locavit Frisinge"… The Annales Ducum Bavariæ record that "Theodo dux" led Bavaria in 712, specifying that he and his son Grimoald placed "sanctum Corbinatium in castro Frisinge".

The Salzburg Annals record that "Theodo dux Bawarie" attacked Rome in 716, and died in 718. The Historia Episcoporum Pataviensium et Ducum Bavariæ records the death in 718 of "Theodo dux". The necrology of Nonnberg records the death "3 Id Dec" of "Theodo dux". 1


Theodo's descendance has not been conclusively established. A member of the Agilolfing dynasty, his father possibly was Duke Theodo IV of Bavaria (d. 680) and his mother was probably Fara of Bavaria (b: 600), daughter of one of the Kings of the Lombards and (her mother) Daughter of Gisulf I of Friuli (b: 577).

Theodo established his capital at Ratisbona (modern Regensburg). He married Folchaid, of the Frankish (possibly Robertian) aristocracy in Austrasia, to build diplomatic ties there. He intervened in Lombard affairs by harbouring the refugees Ansprand and Liutprand, whom he assisted militarily on his return to claim the Iron Crown. Liutprand later married his daughter Guntrude. Theodo also defended his duchy ably from the Avars (with some failure in the east).

Theodo is the patron to the four great missionaries of Bavaria: Saint Rupert, Saint Erhard, Saint Emmeram, and probably Saint Corbinian. He was the first to draw up plans for the Bavarian church, aiming both at a deeper cultivation of the countryside as well as greater independence from the Frankish Kingdom by a closer association with the Pope. He was the first Bavarian duke to travel to Rome, where he conferred with Pope Gregory II. The diocesan seats were placed in the few urban centres, which served as the Duke's seats: Regensburg, Salzburg, Freising and Passau.

Two of his children are involved with the death of Saint Emmeram. Theodo's daughter Uta had become pregnant by her lover. Fearing her father's wrath, she confided to Emmeram and the saint promised to bear the blame, as he was about to travel to Rome. Soon after his departure, Uta's predicament became known and in keeping with the agreement she named Emmeram as the father. Her brother Lantpert went after Emmeram and greeted him as "bishop and brother-in-law," i.e., episcope et gener noster! Then he had Emmeram cut and torn into pieces. Theodo had the remains of the saint moved to Regensburg. Nothing more is known of Lantpert and Uta.

According to the Renaissance historians Ladislaus Sunthaym (c.1440–1512/13) and Johannes Aventinus (1477–1534), Theodo married Regintrud, possibly a daughter of King Dagobert I of Austrasia. However, the Verbrüderungsbuch codex of St Peter's Abbey, Salzburg only mentions one Folchaid, probably a daughter of the Robertian count Theutacar in Wormsgau. 2

  Marriage Information:

Theodo married Folchaid VON WORMSGAU, probably daughter of Gf. Theutacar VON WORMSGAU and Unknown.
