Oda of Gandersheim

Oda of Gandersheim (died 912/919) was a Saxon noblewoman who founded Gandersheim Abbey. She was an ancestor of the Ottonian dynasty.

Oda's mother's name was Aeda and her father's probably Billung. She was married to Liudolf of Saxony, with whom she had 12–14 children, including three sons and a daughter who died young. Her children who survived to adulthood include:

Oda and Liudolf "committed themselves to establishing a convent soon after their marriage." For this purpose, they travelled to Rome to acquire relics of the saints in 845–846. From Pope Sergius II they received not just relics of his predecessors, Innocent I and Anastasius I, but also papal protection for their foundation. A community of nuns was established at Brunshausen in 852 with their daughter Hathumoda as its designated abbess. Construction of a permenant home was begun at Gandersheim, but it was not consecrated until All Saints' Day 881, after Hathumoda's death in 874.

Liudolf died in 866. Oda spent much of her widowhood at Gandersheim. Another daughter, Gerberga, succeeded Hathumoda and was succeeded by a third, Christina. Oda died at Gandersheim in 912 or 919.
