→Impact of Viking Invasions
Although Alfred faced a devastating defeat and was forced to seek refuge in the swamps of Somerset, he was able to reorganize himself and won the crucial battle of Edington. This helped to re-establish Wessex and new boundaries where areas north of Wessex and to the east became Danelaw, or regions where the Danes ruled. Alfred created a series of fortified towns or forts, known as burhs, that made the conquest difficult for Danes or Norse attackers, as they had not developed effective siege warfare tactics. While the invasions by Danes and Norse likely seemed to be a threat to Anglo-Saxon England, it effectively gave Alfred a chance to foster the idea of a unified English speaking kingdom, which was also Christian. This helped it stand as a contrast to the Dane and Norse regions that were polytheistic. Furthermore, Danelaw lacked very strong central governments, where the rulers often had little real power and local warlords were able to do as they please.
