The Hattonids were an important imperial noble family in the first half of the 9th century, during the reigns of the Carolingian kings Charlemagne and Louis the Pious.
They attended empire-wide councils and were given military commands on the borders to defend the empire from Danish Vikings and Slavs.
Hailing from Saxony and Bavaria, where they had many lands and honores, the Hattonids were appointed to prefectures and counties in East Franconia and the central Rhineland from an early date.
The Hattonids were staunch supporters of Louis the Pious and the unity of the Frankish Empire.
On 14 December 840 at Rösebeck [de], Louis dispossessed Banzleib of his benefices and public offices and granted them to Warin, Abbot of Corvey.
