"Odilo, also Oatilo or Uatilo (died 18 January 748) of the Agilolfing dynasty was Duke of Bavaria from 737 until his death. He had the Lex Baiuvariorum compilation edited, the first ancient Germanic law collection of the Bavarians.
Odilo by his Agilolfing descent was an Alemannic nobleman, a son of Duke Gotfrid (d. 709) whom he succeeded in Thurgau until 737, when with the death of Hugbert of Bavaria the older line of the dynasty became extinct and he inherited the rulership of the Duchy of Bavaria.
Odilo presided over the establishment of bishoprics in Bavaria in 739, when the four dioceses of Regensburg, Freising, Passau, and Salzburg were established by St. Boniface, who in 741 also founded the Diocese of Würzburg in adjacent Franconia. His measures sparked a revolt by Bavarian nobles and the duke temporarily had to seek refuge at the court of the Frankish Mayor of the Palace Charles Martel." - (en.wikipedia.org 12.08.2021)
