Hedwiga of Babenberg
|Duchess of Saxony|
|Died||24 December 903|
|Noble family||Elder House of Babenberg|
|Spouse(s)||Otto I, Duke of Saxony|
|Father||Henry of Franconia|
Hedwiga (also known as Hathui; c. 850/55 - 24 December 903), was Duchess of Saxony from about 880 until her death, by her marriage with the Liudolfing duke Otto the Illustrious. She is the mother of King Henry the Fowler.
Her parentage is not clearly stated in any contemporary source. One probable conjecture is that she was the daughter of Henry of Franconia (d. 886), documented as a princeps militiae of the East Frankish king Louis the Younger and dux of Austrasia under emperor Charles the Fat. Dux Henry died fighting against the Vikings during the Siege of Paris in West Francia.
Hedwiga married Otto (d. 912), a younger son of late Saxon count Liudolf. Her husband's family had already achieved a dominating position in the stem duchy of Saxony; Otto's sister Liutgard was married to King Louis the Younger about the same time. With the support of his brother-in-law King Louis the Younger, Otto succeeded as head of the Liudolfing dynasty and heir of the Saxon estates, when his elder brother Bruno was killed fighting against the Vikings in the 880 Battle of Lüneburg Heath. Hedwiga's husband remained a loyal supporter of the Carolingian dynasty, while he rose to the position of a Saxon duke (Herzog).
Hedwiga and Otto had three sons: Henry the Fowler (who succeeded his father in 912) and his elder brothers Thankmar and Liudolf, who both died young; as well as a daughter, Oda who married King Zwentibold of Lotharingia, an illegitimate son of Emperor Arnulf, in 897.
