April 23rd 1016 – Edmund Ironside succeeds his father Æthelred the Unready as king of England.

November 30th 1016 – Edmund Ironside, English king dies, possibly murdered (b. 993)

"On 30 November 1016, Edmund died. The location of his death is uncertain though it is generally accepted that it occurred in London, rather than in Oxford where Henry of Huntingdon claimed it to be in his sordid version of events, which included Edmund’s murder by suffering multiple stab wounds whilst on a privy, while tending to a call of nature. Geoffrey Gaimar states a similar occurrence with the weapon being a crossbow, but with a number of other medieval chroniclers including the Encomium Emmae Reginae not mentioning murder, it is thought Edmund’s cause of death may possibly have been caused by wounds received in battle or by some disease, but it is certainly a possibility that he was murdered. Edmund was buried near his grandfather Edgar at Glastonbury Abbey in Somerset, however the abbey was destroyed during the Dissolution of the Monasteries in the 16th century, any remains of a monument or crypt would have been plundered and the location of his remains is unclear."
