The period of the Scandinavian invasions
Viking invasions and settlements
Small scattered Viking raids began in the last years of the 8th century; in the 9th century large-scale plundering incursions were made in Britain and in the Frankish empire as well. Though Egbert defeated a large Viking force in 838 that had combined with the Britons of Cornwall and Aethelwulf won a great victory in 851 over a Viking army that had stormed Canterbury and London and put the Mercian king to flight, it was difficult to deal with an enemy that could attack anywhere on a long and undefended coastline. Destructive raids are recorded for Northumbria, East Anglia, Kent, and Wessex.
A large Danish army came to East Anglia in the autumn of 865, apparently intent on conquest. By 871, when it first attacked Wessex, it had already captured York, been bought off by Mercia, and had taken possession of East Anglia. Many battles were fought in Wessex, including one that led to a Danish defeat at Ashdown in 871. Alfred the Great, a son of Aethelwulf, succeeded to the throne in the course of the year and made peace; this gave him a respite until 876. Meanwhile the Danes drove out Burgred of Mercia, putting a puppet king in his place, and one of their divisions made a permanent settlement in Northumbria.
Alfred was able to force the Danes to leave Wessex in 877, and they settled northeastern Mercia; but a Viking attack in the winter of 878 came near to conquering Wessex. That it did not succeed is to be attributed to Alfred’s tenacity. He retired to the Somerset marshes, and in the spring he secretly assembled an army that routed the Danes at Edington. Their king, Guthrum, accepted Christianity and took his forces to East Anglia, where they settled.
The importance of Alfred’s victory cannot be exaggerated. It prevented the Danes from becoming masters of the whole of England. Wessex was never again in danger of falling under Danish control, and in the next century the Danish areas were reconquered from Wessex. Alfred’s capture of London in 886 and the resultant acceptance of him by all the English outside the Danish areas was a preliminary to this reconquest. That Wessex stood when the other kingdoms had fallen must be put down to Alfred’s courage and wisdom, to his defensive measures in reorganizing his army, to his building fortresses and ships, and to his diplomacy, which made the Welsh kings his allies. Renewed attacks by Viking hosts in 892–896, supported by the Danes resident in England, caused widespread damage but had no lasting success.
Alfred’s government and his revival of learning
Good internal government contributed to Alfred’s successful resistance to the Danes. He reorganized his finances and the services due from thegns, issued an important code of laws, and scrutinized carefully the exercise of justice. Alfred saw the Viking invasions as a punishment from God, especially because of a neglect of learning, without which men could not know and follow the will of God. He deplored
the decay of Latin and enjoined its study by those destined for the church, but he also wished all young freemen of adequate means to learn to read English, and he aimed at supplying men with “the books most necessary for all men to know,” in their own language.Alfred had acquired an education despite great difficulties, and he translated some books himself with the help of scholars from Mercia, the Continent, and Wales. Among them they made available works of Bede and Orosius, Gregory and Augustine, and the De consolatione philosophiae of Boethius. Compilation of the Anglo-Saxon Chronicle began in his reign. The effects of Alfred’s educational reforms can be glimpsed in succeeding reigns, and his works continued to be copied. Only in his attempt to revive monasticism did he achieve little, for the monastic idea had lost its appeal—in England as well as on the Continent—during the Viking Age.
