Changes

When Alfred does die in 899, rebellion by Aethelwald starts that sees him combining his forces with invading Danes and Danes from East Anglia. Edward, son of Alfred, had succeed Alfred but some see him as not the legitimate king, as Alfred took the crown from Aethelwald early in his reign because Aethelwald was seen as incompetent and unable to lead against the Danes. The Anglo-Saxon Chronicle suggests Aethelward may have been recognised as king in Northumbria at this time. Aethelwald also convinces the Danes that he is the rightful king, although he is unsuccessful in convincing anyone in Wessex of this. The Danes began raiding Wessex which eventually led to an invasion by Wessex against East Anglia, specifically against King Eohric who had sided with Aethelwald. At a great battle, the Battle of Holme, Eohric, Aethelwald, and other prominent Danes die, but Wessex forces retreat from East Anglia.

In Season 3, Uhtred appears to possibly change his loyalties as he leaves Wessex after his wife dies. This is because he killed a priest who had insulted her after her death. Uhtred is now governor of London and, although Merica, led by Æthelred, technically rule London, it is Wessex that has the real authority. In fact, Mercia is not allowed to have a king but only a lord, keeping Wessex in charge of its affairs. After leaving Wessex for some time, Uhtred comes back and serves Æthelflæd as he cares for her and keeps his oath to her to protect her. He thus continues fighting for Wessex and serving under Edward, the son and successor to Alfred.
