The descent of the East Frankish Luitpoldings has not been conclusively established. The progenitor of the family, Margrave Luitpold of Bavaria, possibly was a relative of the Early medieval Huosi noble family and maybe related to the Imperial Carolingian dynasty by Emperor Arnulf's mother Liutswind. In 893 Arnulf appointed him margrave in Carinthia and Pannonia, succeeding the Wilhelminer margrave Engelschalk II. Luitpold was able to enlarge his Bavarian possessions around Regensburg and in the adjacent March of the Nordgau, he became a military leader during the Hungarian invasions and was killed in the 907 Battle of Pressburg.
