Alfred, the Great c. 848-c. 900. King of Wessex from 871. He defended England against Danish invasion, founded the first English navy, and put into operation a legal code. He encouraged the translation of works from Latin (some of which he translated himself), and promoted the development of the Anglo-Saxon Chronicle. Alfred was born at Wantage, Berkshire, the youngest son of Ethelwulf (died 858), king of the West Saxons. In 870 Alfred and his brother Ethelred fought many battles against the Danes. He gained a victory over the Danes at Ashdown 871, and succeeded Ethelred as king in Apr 871 after a series of defeats. Five years of uneasy peace followed while the Danes were occupied in other parts of England. In 876 the Danes attacked again, and in 878 Alfred was forced to retire to the stronghold of Athelney, from where he finally emerged to win the victory of Edington, Wiltshire. By the Peace of Wedmore 878 the Danish leader Guthrum (died 890) agreed to withdraw from Wessex and from Mercia west of Watling Street. A new landing in Kent encouraged a revolt of the East Anglian Danes, which was suppressed 884-86, and after the final foreign invasion was defeated 892-96, Alfred strengthened the navy to prevent fresh incursions.
