Liudolf (c. 805 - 12 March 864 or 866) was a Saxon count, son of Count (German: Graf) Brun (Brunhart)[1] and his wife, Gisla von Verla;[2][clarification needed] later authors called him Duke of the Eastern Saxons (dux orientalis Saxonum, probably since 850) and Count of Eastphalia. Liudolf had extended possessions in eastern Saxony, and was a leader (dux) in the wars of King Louis the German against Normans and Slavs. The ruling Liudolfing House, also known as the Ottonian dynasty, is named after him; he is its oldest verified member.
Before 830 Liudolf married Oda, daughter of a Frankish princeps named Billung and his wife Aeda. Oda died on 17 May 913, supposedly at the age of 107.[3]
They had six children:[4]
By marrying a Frankish nobleman's daughter, Liudolf followed suggestions set forth by Charlemagne about ensuring the integrity of the Frankish Empire in the aftermath of theSaxon Wars through marriage.
In 845/846, Liudolf and his wife founded a house of holy canonesses, duly established at their proprietary church in Brunshausen around 852, and moved in 881 to formGandersheim Abbey. Liudolf's minor daughter Hathumoda became the first abbess.
Liudolf is buried in Brunshausen.
