Alfred the Great (Old English: "elf counsel" or "wise elf"; 849 - 26 October 899) was King of Wessex from 871 to 899.

Alfred was the youngest son of King Athelwulf of Wessex. Taking the throne after the death of his brother Athelred, Alfred spent several years dealing with Viking invasions. After a decisive victory in the Battle of Edington in 878 Alfred made an agreement with the Vikings, creating what was known as Danelaw in the North of England. Alfred also oversaw the conversion of the Viking leader, Guthrum.

Alfred successfully defended his kingdom against the Viking attempt at conquest, and by the time of his death had become the dominant ruler in England. He is one of only two English monarchs to be given the epithet "the Great", the other being the Scandinavian Cnut the Great. He was also the first King of the West Saxons to style himself "King of the Anglo-Saxons". Details of Alfred's life are described in a work by the 9th-century Welsh scholar and bishop Asser.

Alfred had a reputation as a learned and merciful man of a gracious and level-headed nature who encouraged education, proposing that primary education be conducted in English rather than Latin, and improved his kingdom's legal system, military structure, and his people's quality of life. In 2002 Alfred was ranked number 14 in the BBC's poll of the 100 Greatest Britons.

Alfred was born in the village of Wanating, now Wantage, historically in Berkshire but now in Oxfordshire. He was the youngest son of King Æthelwulf of Wessex by his first wife, Osburh.[c]

In 853, at the age of four, Alfred is reported by the Anglo-Saxon Chronicle to have been sent to Rome where he was confirmed by Pope Leo IV, who "anointed him as king".[3] Victorian writers later interpreted this as an anticipatory coronation in preparation for his eventual succession to the throne of Wessex. This is unlikely; his succession could not have been foreseen at the time as Alfred had three living elder brothers. A letter of Leo IV shows that Alfred was made a "consul"; a misinterpretation of this investiture, deliberate or accidental, could explain later confusion.[4] It may also be based on Alfred's later having accompanied his father on a pilgrimage to Rome where he spent some time at the court of Charles the Bald, King of the Franks, around 854-855.

On their return from Rome in 856 Athelwulf was deposed by his son Athelbald. With civil war looming the magnates of the realm met in council to hammer out a compromise. Athelbald would retain the western shires (i.e. historical Wessex), and Athelwulf would rule in the east. When King Athelwulf died in 858 Wessex was ruled by three of Alfred's brothers in succession: Athelbald, Athelberht and Athelred.

Bishop Asser tells the story of how as a child Alfred won as a prize a book of Saxon poems, offered by his mother to the first of her children able to memorize it.[6] Legend also has it that the young Alfred spent time in Ireland seeking healing. Alfred was troubled by health problems throughout his life. It is thought that he may have suffered from Crohn's disease.[7] Statues of Alfred in Winchester and Wantage portray him as a great warrior. Evidence suggests he was not physically strong and, though not lacking in courage, he was noted more for his intellect than as a warlike character.
