Athelred of Wessex
Athelred had not expected to reign, but when his brother Ethelbert died in 866, Athelred became the king of Wessex. This was just after the arrival of the Great Heathen Army in East Anglia. For a time they were more interested in Northumbria. They gained control of York and moved south into Mercia then made their winter camp in Nottingham.
