King of England (939–946), half-brother of Æthelstan, who reconquered the Norse-held north and revived English monasticism before being killed at a feast at twenty-five.
Edmund I, sometimes called the Magnificent, was king of England from 939 to 946. A half-brother of Æthelstan, he came to the throne at eighteen and at once faced the unravelling of his brother's conquests, as the Norse of Dublin reoccupied York and the north.
Edmund fought back with energy, recovering the Five Boroughs of the Danelaw and finally reasserting English control over Northumbria. A patron of the monastic revival then beginning under Dunstan, whom he installed at Glastonbury, he seemed set for a great reign when he was suddenly killed in a scuffle at a feast in 946, still only in his mid-twenties.
Edmund was born in 921, a son of Edward the Elder by a later marriage and thus a half-brother of Æthelstan, at whose court he was raised. He fought at his brother's side at the Battle of Brunanburh in 937, though still only about sixteen, and on Æthelstan's death in 939 he succeeded to the throne.
He inherited a kingdom whose hard-won unity was immediately tested, as the Viking leader Olaf Guthfrithson swept back into York and overran the north-east Midlands.
Edmund is remembered as a vigorous, forceful young king — a fighter who recovered by hard campaigning what had been lost at the start of his reign, and who threw royal support behind the reform of the English Church. The bynames later attached to him, "the Magnificent" and "the Deed-doer", capture the impression of restless energy his short reign left.
He also showed a capacity for the politics of mercy and reform. He spared and reconciled defeated enemies, sponsored the young Dunstan and the beginnings of the great monastic revival, and issued law-codes concerned with reducing blood-feud and protecting the Church. The abrupt violence of his death — cut down in a brawl at his own feast — froze that promise, leaving the sense of a formidable reign broken off unfinished.
Edmund's first years were spent recovering the north. After early setbacks he retook the Five Boroughs — Leicester, Nottingham, Derby, Lincoln, and Stamford — from the Norse in 942, a feat celebrated in a poem in the Anglo-Saxon Chronicle, and by 944 he had driven the Viking kings from York and restored English rule over Northumbria. He also campaigned into Strathclyde, which he ravaged and handed to the king of Scots in return for an alliance.
At home he became a patron of Church reform, appointing Dunstan abbot of Glastonbury and supporting the monastic movement that would flower under his successors. His law-codes worked to curb the violence of the blood-feud and to strengthen public order.
On 26 May 946, at a feast at Pucklechurch in Gloucestershire, Edmund was killed in a sudden affray — by tradition, while intervening to seize an exiled outlaw named Leofa who had returned to the hall. He was about twenty-five, and was buried at Glastonbury near his friend Dunstan. His young sons being infants, he was succeeded by his brother Eadred.
Edmund I is remembered as a king of great early promise cut brutally short: the young warrior who saved his brother's united England by reconquering the north, and who set in motion the monastic revival that would define the tenth-century English Church. His sons Eadwig and Edgar would both later reign, and through Edgar his line would continue to the end of Anglo-Saxon England.
