Genealogy of House of Billung
the House of Billung
The House of Billung, to which belonged the mother of Otto the Great, was a dynasty of Saxon noblemen in the ninth through twelfth centuries. Otto the Great’s father was Henry I the Fowler, the son of Otto I the Illustrious (c. 830/40 – 912), whose mother was Oda Billung, the granddaughter of Charlemagne’s son Pepin, and Bertha of Toulouse, the daughter of Guillaume of Gellone. Oda Billung’s mother, Aeda of Italy, would have been the step-sister of Bernard of Italy (797 – 818), the illegitimate son of of Pepin of Italy, brother of Louis the Pious. The family itself is also sometimes known as the Liudolfings (Liudolfinger), after its earliest known member, Oda’s husband, Liudolf, Duke of Saxony (d. 866). In the middle of the tenth century, when the Saxon dukes of the House of Liudolfing had also become German kings, Otto the Great entrusted more and more of his ducal authority to Hermann Billung. For five generations, the House of Billung ruled the Duchy of Saxony. The House of Billung merged into the House of Welf and House of Ascania (also known as House of Anhalt) when Henry the Black’s father-in-law, Magnus, Duke of Saxony (c. 1045 – 1106), died without a male heir. The family’s property was divided between his two daughters by his wife Sophia of Hungary, the daughter of Béla I of Hungary and Richeza of Poland, granddaughter of Boleslav the Brave. Henry the Black married Magnus’ daughter Wulfhilde. Their son, Henry the Proud, married Gertrude of Süpplingenburg, the daughter Lothair III. Their son was Henry the Lion (1129/1131 – 1195), who married Matilda of England, the daughter of Henry II and Eleanor of Aquitaine.
