Edmund I

Edmund I (920/921 – 26 May 946), elder son of Edward the Elder, succeeded his half-brother Æthelstan as king in 939. At first he lost the north to the Viking king Anlaf Guthfrithson, but after Anlaf's death in 941 he recovered the Five Boroughs and expelled the Viking kings of York in 944, reuniting England.

In 945 he ravaged Strathclyde and ceded it to Malcolm I of Scotland. Edmund was killed in a brawl at Pucklechurch in 946, and was succeeded by his brother Eadred.
