Historical Background
Cuthred Aethelwulfing is born circa 845, from the House of Wessex. He is the youngest son of King Æthelwulf of Wessex (r. 839–858), was born in the village of Wanating. During his childhood, in 853 at the age of four, Cuthred 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". 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 Cuthred had three living elder brothers.

On his return to Rome, Cuthred saw his father Æthelwulf was deposed by his son Æthelbald. With civil war looming the magnates of the realm met in council to hammer out a compromise. Æthelbald would retain the western shires (i.e. historical Wessex), and Æthelwulf would rule in the east. When King Æthelwulf died in 858 Wessex was ruled by three of Cuthred's brothers in succession: Æthelbald, Æthelberht and Æthelred.

After the death of his brother Æthelberht in 863, Cuthred at 18, was chosen and accepted to be the next successor of the throne of the Kingdom of Wessex. His first solo-rule soon begin with the kingdom and peace with neighboring kingdoms such as the Mercia, Cornubia (modern day Cornwall), and the Kingdom of East Engle. Two years later Aethelred was made Cuthred's co-ruler, with Cuthred controlling the kingdom. In 868, with the threating war with the Cornubia, when the Vikings invasion of Engaland (now England).
