Luitpold or Liutpold (modern Leopold) (died 4 July907), perhaps of the Huosi family or related to the Carolingians, was the father of the great Luitpolding dynasty which dominated Bavaria and Carinthia until the mid-tenth century.
In 893, Luitpold was created margrave of Carinthia and Upper Pannonia by the Emperor Arnulf. He soon acquired counties on the Danube and in the Nordgau, even getting Regensburg around 895, and thereby setting himself up as the most prominent of Bavaria's aristocracy. He was a loyal friend of the Carolingian monarchs and enjoyed their support. He was entrusted with defence of the Hungarian and Moravian borders. In 898, he fought successfully against Mojmír II, king of Great Moravia, on behalf of the rebel Svatopluk II and forced Mojmír to become a vassal of Arnulf. In 903, he had the title dux Boemanorum, "duke of Bohemia." On 4 July907, Luitpold died in the Battle of Bratislava.
