The Battle

History & Significance

Within weeks of Aethelstan's death in 939, Olaf Guthfrithson — the Dublin Norse king who had fought at Brunanburh — invaded England. The young King Edmund I could not stop him. Under Archbishop Oda's mediation, the Treaty of Leicester restored the Five Boroughs (Lincoln, Nottingham, Derby, Leicester, Stamford) to Norse rule. This dramatic reversal showed how dependent English unity had been on Aethelstan's personal authority.
