In the calendar, the year 1016 CE was in the late Anglo-Saxon period of England during the broader Viking Age. King Ethelred the Unready died in 1016, and Edmund Ironside succeeded him as king of England. Later that year, the Battle of Assandun occurred between Edmund Ironside and Canute the Great. Following the battle, the two rulers reportedly agreed to divide the kingdom, but Edmund died within months, and Canute became king of a unified England, establishing Danish rule over the whole realm. The events of 1016 contributed to the transition from Anglo-Saxon kingship to Danish influence and helped shape the subsequent history of England.
