The Battle of Edington or Battle of Ethandun was fought in May 878 between the West Saxon army of King Alfred the Great and the Great Heathen Army led by the Danish warlord Guthrum. The battle took place near Edington in Wiltshire, where Alfred secured a decisive victory that halted the Viking advance into Wessex.

The engagement followed a period of sustained Danish incursions into Anglo-Saxon territory. In early 878, Guthrum launched a surprise attack on Chippenham, forcing Alfred into hiding in the marshes of Athelney. After rallying local forces, Alfred confronted and defeated Guthrum at Edington, then laid siege to the Viking position, compelling their surrender.

Following the battle, Guthrum agreed to terms that included his baptism, withdrawal to East Anglia, and the establishment of peace through the Treaty of Wedmore. The outcome preserved Wessex as an independent kingdom and marked a turning point in the Viking wars, laying foundations for the eventual unification of England.
