General Notes

Aethelwulf, also spelled ETHELWULF (d. 858), Anglo-Saxon king in England, the father of King Alfred the Great.  As ruler of the West Saxons from 839 to 856, he allied his kingdom of Wessex with Mercia and thereby withstood invasions by Danish Vikings.

The son of the great West Saxon king Egbert (ruled 802-839), Aethelwulf ascended the throne four years after the Danes had begun large-scale raids on the English coast.  In 851 he scored a major victory over a large Danish army at a place called Aclea in Surrey.  Aethelwulf then married his daughter to the Mercian king Burgred (853), and in 856 he himself married the daughter of Charles II the Bald, king of the West Franks.  Aethelwulf was deposed by a rival faction upon his return from a pilgrimage to Rome in 856, but he continued to rule Kent and several other eastern provinces until his death.  In addition to Alfred the Great (ruled 871-899), three of Aethelwulf's other sons became kings of Wessex.  [Encyclopaedia Britannica]
