Mercia
A new Mercian king, Raedwulf, was killed by Viking raiders in 844. In 855 Viking bands were recorded as being in Mercia near Wrekin. But the year 865 saw a major change in activity by the Scandinavian invaders. This was a much larger military force than had been seen before. The arrival of the Great Heathen Army in East Anglia. For a time the Danes (Vikings) were more interested in Northumbria. They gained control of York and moved south into Mercia then camped for the winter in Nottingham. In the spring of 868 a combined Mercian and West Saxon army came against the Vikings, but there was no battle. The Mercian king Burghred made a peace treaty with the invaders, who then moved north to York. In 873 Burghred was forced out of Mercia by the Vikings who then set their own choice of King, Ceowulf. In 874 the heathen army split with Halfdan, one of the leaders taking his band north. In 878 the Vikings in Mercia were attacked and defeated by King Alfred of Wessex. They converted to Christianity and settled on the land in East Anglia.
