Edmund II (c. 989 - November 30, 1016) was a King of England (1016). He was a son of King Ethelred II and Aelgifu of Northampton; Edward the Confessor was his half-brother. He was known as Ironside for his military prowess.
He was elected king of England by the population of London on his father's death in 1016, but his rival, Canute the Great, enjoyed greater support throughout the country.
Edmund married Ealdgyth (Edith) of East Anglia (born c. 986), the daughter of Mocar and Edgitha, in 1015.
The known children of Edmund and Ealdgyth (Edith) are:
1. Edward the Exile "Aetheling" (1016 - 1057), who was born in Wessex and died in London and who married Agatha around the year 1035.
2. Edmund (born c. 1017 in Wessex).
Edmund II was eventually defeated by the Danes, and was allowed by Canute to keep the kingdom of Wessex, on the understanding that whichever of them survived the other would become ruler of the whole of England.
Shortly after making this agreement, Edmund II died, on November 30, 1016, and was buried at Glastonbury. Some say he was stabbed in the bowels while going to the privy.
