The Viking Great Army landed in East Anglia in late 865 and over the following fifteen years it fought numerous battles in all four Anglo-Saxon kingdoms, made and broke peace treaties, and deposed or killed at least three Anglo-Saxon kings, replacing them with its own appointees. It had a major impact on English society, initiating extensive transformations in Anglo-Saxon society, culture, economy, and political organization. Previous Viking armies had raided only in the summer months, but the Great Army was a constant presence over this period, overwintering at various locations in northern and eastern England. This presence changed the political, economic, and social landscape of England forever, but historical sources say very little about it. Now, new archaeological evidence has revealed the location of two of its camps, and at least fifty other places it visited. This book describes life in the tents and towns that the Viking Great Army inhabited: the treasure, tools, and weapons found in the camps and what they reveal about how the groups that made up the Army lived and the activities that took place, including the processing and trading of loot, the minting of coins, and the manufacture of jewelry. What emerges is evidence of a rich and diverse community whose impact on England can be traced to the present day.
