Gerold, Prefect of Bavaria

Gerold was an Alamannian nobleman who served the Frankish King, Charlemagne, as Margrave of the Avarian March and Prefect of Bavaria in what is now South-Eastern Germany. Gerold played a significant role in the integration of Bavaria into the Frankish Kingdom during Carolingian expansion in the late 8th, and early 9th centuries. Gerold both aided the continuity of Agilofing rule of Bavaria, as well as took steps to integrate Bavarians into the wider scope of the Frankish Kingdom. Gerold was related both to the Agilofing family, the ruling class of Bavaria, as well as the Carolingian family. The Agilofings had ruled Bavaria since Duke Garibald I in 548. Gerold was born into the Agilofings, and his sister Hildegard was married to Charlemagne in 771. From these familial connections, he was appointed Prefect of Bavaria following the deposition of Duke Tassilo III in 788. Gerold was heralded as a superb military commander, giving rise to his promotion to Prefect as a defender of the eastern border of the Frankish Kingdom. In 799, Gerold is said to have fallen in battle against the Avars, shortly after the same Avars killed his ally, Erich, Duke of Friuli, through treachery.
