Osburh or Osburga (also Osburga Oslacsdotter) was the first wife of King Æthelwulf of Wessex and mother of King Alfred the Great. Alfred's biographer, Asser, described her as "a most religious woman, noble in character and noble by birth".[1]
Osburh's existence is known only from Asser's Life of King Alfred. She is not named as witness to any charters, nor is her death reported in the Anglo-Saxon Chronicle. So far as is known, she was the mother of all Æthelwulf's children, his five sons Æthelstan, Æthelbald, Æthelberht, Æthelred and Alfred, and his daughter Æthelswith, wife of King Burgred of Mercia.
Osburh is best known from Asser's story about a book of Saxon songs which she showed to her sons, offering to give the book to whoever could first memorise it, a challenge which Alfred took up and won. This exhibits high-status ninth-century women's interest in books and their role in educating their children.[2]
Osburh was the daughter of Oslac (who is also only known from Asser's Life), King Æthelwulf's pincerna (butler), an important figure in the royal court and household.[3] Oslac is described as a descendant of King Cerdic's Jutish nephews, Stuf and Wihtgar, who conquered the Isle of Wight.[4]
