Editing Edmund the Martyr (section)

===Death and burial===
For decades after the [[Lindisfarne#Viking raid on the monastery %28793%29|Viking raid on Lindisfarne in 793]], their attacks on England were mainly raids on isolated [[Monastery|monastic communities]]. According to the ''[[Annales Bertiniani]]'' and the ''Anglo-Saxon Chronicle'', a larger-scale attack occurred in {{circa|844}}. By the end of the decade the Vikings had started to over-winter in England.{{sfn|Oliver|2013|p=168}} In the autumn of 865 a force probably numbering over 5,000 combatants, described by the ''Anglo-Saxon Chronicle'' as "a great heathen army", came to East Anglia. Edmund made peace with them and gave them horses and other supplies, and they stayed there until the summer of 866, when they moved on to York.{{sfnm|1a1=Abels|1y=1998|1pp=113-115|2a1=Whitelock|2y=1979|2p=191}} The army attacked Mercia by the end of 867 and made peaceful terms with the Mercians; a year later the Vikings returned to East Anglia.{{sfn|Oliver|2013|p=172}} 

The ''Anglo-Saxon Chronicle'', which generally described few matters relating to the East Angles and their rulers, relates that "here the army rode across Mercia into East Anglia, and took winter-quarters at Thetford; and that winter King Edmund fought against them, and the Danish took the victory, and killed the king and conquered all that land".{{sfn|Swanton|1997|p=70}} Where Edmund was killed and whether he died in battle or was murdered by the Danes afterwards is not known.{{sfn|Butler|Thomas|Burns|1997|p=173}} The Great Heathen Army went on to invade [[Wessex]] in late 870, where they were confronted by [[Æthelred of Wessex]] and his brother, the future [[Alfred the Great]].{{sfn|Yorke|1995|p=109}}{{sfn|Ridyard|1988|p=211}}

Edmund was buried in a wooden chapel near to where he was killed. At a date generally assumed by historians to have been during the reign of [[Æthelstan]], who became king of the Anglo-Saxons in 924, Edmund's body was [[Translation (relic)|translated]] from {{lang|ang|Haegelisdun}}—the location of which has never been conclusively identified—to ''{{lang|ang|Beodricesworth}}'', now modern [[Bury St Edmunds]].{{sfn|Young|2018|p=75}}{{sfn|Ridyard|1988|p=213}} In 925 Æthelstan founded a religious community to take care of Edmund's [[shrine]].{{sfn|Farmer|2011|pp=136{{ndash}}137}}
