Æthelwine (Ailwyn, died 992) was Ealdorman of East Anglia and one of the leading noblemen in the kingdom of England in the later 10th century. As with his kinsmen, the principal source for his life is Byrthferth’s life of Oswald of Worcester. Although Byrthferth and Ramsey Abbey remembered Æthelwine favourably, calling him Dei amicus (friend to God) , the monks of nearby Ely saw him as an enemy who had seized their lands.

Æthelwine was a son of Æthelstan Half-King , but probably not the eldest son has his brother Æthelwald seems to have succeeded their father on his retirement in 956. Æthelwine appears to have followed Æthelwald in office from 962. He was a benefactor of the new Minister at Winchester, and of Ramsey Abbey.

Following the death of King Edgar, Æthelwine was, with Oswald of Worcester and Dunstan, a leader among the supporters of Edgar’s oldest son Edward, which placed him in opposition to his former sister-in-law Dowager Queen Ælfthryth and Ælfhere, Earldorman of Mercia. During the anti-monastic reaction in Edward’s short reign, Æthelwine is portrayed as a stalwart supporter of the monks, but the record suggests that he took advantage of the weakness of Royal government to dispossess the monks of Ely of lands.

Following the death of Ælfhere in 983, and the withdrawal of the Queen Mother from the court soon after the death of Bishop Æthelwald of Winchester in 984, Æthelwine became the leading lay figure at the court of the young King Æthelred. His death in 992 probably marks the beginning of Æthelred’s personal reign.

Æthelwine’s death is recorded by the Anglo-Saxon Chronicle. Byrhferth provides more detail, reporting that, perhaps following a lengthy illness, Æthelwine was it attended at his death by Prior Germanus, and Ælfheah, later Archbishop of Canterbury. His remains were moved to Ramsey where the monks kept a vigil overnight before he was buried there. (ref 33)
