dmund Ironside (?981-1016), king of England, the son of Ethelred the Unready, succeeded his father in 1016. Only London acknowledged him as king, the rest of England accepting the rule of Canute. For some months Edmund engaged in the hopeless task of attempting to recover England from the Danes. By the treaty of Olney, Edmund received Wessex, East Anglia, Essex, and London, while Canute held Northumbria and Mercia. [World Wide Illustrated Encyclopedia, 1935]

Edmund II, called Ironside (981?-1016), Saxon king of the English (1016), son of King Ethelred the Unready. When Ethelred died, Edmund was chosen king by the people of London, but Canute II, king of Denmark, who was leading an invasion of England, secured the support of the council (witenagemot) at Southampton and of Edric (flourished 1001-17), Ethelred's son-in-law. Edmund met the Danes in battle, winning several engagements and relieving Canute's siege of London. He was defeated at Assandun (now Ashington), however, through the treachery of Edric, who had pretended to desert Canute. A truce was arranged between Canute and Edmund; Edmund was permitted to rule the south of England until his death later in the year, when it reverted to Canute. [Microsoft Encarta 98 Encyclopedia]
