Edmund, the name of two Anglo-Saxon kings.

Edmund I (922?-946), called “the Deeddoer” and “the Magnificent,” reigned from 940 to 946. He succeeded his half-brother Athelstan, grandson of Alfred the Great. Edmund had already won prominence in the victory over Danish invaders in the Battle of Brunanburh in 937. The Danes returned in 940 and won control of much of northern England, but in 944 Edmund regained the territory. In 945 Edmund conquered Strathclyde (southwestern Scotland and northwestern England) and gave it to his ally, Malcom I of Scotland.

Edmund II (980?-1016), called “Ironside,” reigned for seven months in 1016. He succeeded his father Ethelred the Unready during a war with Danish invaders under Knut (Canute). Edmund won several battles but was finally defeated. The two rivals then agreed to divide England, Edmund taking the south, Knut the north. Edmund died soon after, and Knut reigned over all England.
