Died: 1016

Edmund was King of England for only a few months. After the death of his father, Æthelred II, in April 1016, Edmund led the defense of the city of London against the invading Knut Sveinsson (Canute I), and was proclaimed king by the Londoners.

Meanwhile, the Witan (Council), meeting at Southampton, chose Canute as King. After a series of inconclusive military engagements, in which Edmund performed brilliantly and earned the nickname ""Ironside," he defeated the Danish forces at Oxford, Kent, but was routed by Canute's forces at Ashingdon, Essex. A subsequent peace agreement was made, with Edmund controlling Wessex and Canute controlling Mercia and Northumbria. It was also agreed that whoever survived the other would take control of the whole realm. Unfortunately for Edmund, he died in November, 1016, transferring the Kingship of All England completely to Canute.
