Edmund the Martyr (also known as St Edmund and Edmund of East Anglia, died 20 November 869) was king of East Anglia from about 855 until his death. Few historical facts about Edmund are known, as East Anglia was devastated by the Vikings, who destroyed any contemporary evidence of his reign. Coins minted by Edmund indicate that he succeeded Æthelweard of East Anglia, as they shared the same moneyers. He is thought to have been of East Anglian origin, but 12th-century writers produced fictitious accounts of his family, succession and his rule as king. Edmund's death was mentioned in the Anglo-Saxon Chronicle, which relates that he was killed in 869 after the Great Heathen Army advanced into East Anglia. Medieval versions of Edmund's life and martyrdom differ as to whether he died in battle fighting the Great Heathen Army or if he met his death after being captured and then refusing the Viking leaders' demand that he renounce Christ. A popular cult emerged after Edmund's death, and he was canonised by the Church. A series of coins commemorating him was minted from around the time East Anglia was absorbed by the kingdom of Wessex in 918, and in about 986, the French monk Abbo of Fleury wrote of his life and martyrdom. During the 10th century, Edmund's remains were translated from an unidentified location in East Anglia to Beodericsworth (modern Bury St Edmunds); they were temporarily moved to London for safekeeping in 1010.
