Gerold Prefect of Bavaria

  General Notes:

Gerold (died 799) was an Alamannian nobleman, serving the Frankish King as Margrave of the Avarian March and Prefect of Bavaria. Gerold played a significant role in the integration of Bavaria into the Frankish Kingdom. Being related to the family of the Agilolfings, he was appointed Prefect of Bavaria after the deposition of Duke Tassilo III in 788. In 799 he fell in a battle against the Avars, a short while after Eric of Friuli was killed by the treachery of the same.
