The Battle

History & Significance

Following the expulsion of the Mercian king Burgred from Repton in 874, the Great Heathen Army established the Five Boroughs — Derby, Leicester, Lincoln, Nottingham, and Stamford — as the administrative centres of the Danelaw in the East Midlands. Derby (Northworthy, later Deoraby — the settlement by the deer) became a Danish military base with its own jarl. The Five Boroughs system created a Scandinavian political structure in the heart of England that persisted until Aethelflaed's campaigns forty years later.
