[1] Liudolf had extended possessions in the western Harz foothills and on the Leine river, he also served as a military leader (dux) in the wars of the East Frankish king Louis the German against Viking invasions, and the Polabian Slavs.

[2] Later authors called Liudolf a duke of the Eastern Saxons (dux Orientalis Saxonum, probably since 850) and count of Eastphalia.

By marrying a Frankish nobleman's daughter, Liudolf followed suggestions set forth by Charlemagne about ensuring the integrity of the Carolingian Empire in the aftermath of the Saxon Wars through marriage.

The monastery, duly established at their proprietary church in Brunshausen,[9] was consecrated by the Hildesheim bishop Altfrid and Liudolf's minor daughter Hathumoda became its first abbess.

[3] The convent was relocated in 881 to form Gandersheim Abbey, elevated to an Imperial monastery by Liudolf's grandson Henry the Fowler in 919.
