King Æthelred I of Northumbria was murdered in Corbridge by a group of his ealdormen, Ealdred and Wada, who sought to greater influence in the region. Following the king's death, the patrician Osbald was crowned to take his place, though he abdicated after 27 days. The swift transition of power marked a tumultuous period in Northumbrian politics.
