Æthelred, Lord of the Mercians became ruler of English Mercia shortly after the death or disappearance of its last king, Ceolwulf II in 879.

He was probably the leader of an unsuccessful Mercian invasion of Wales in 881, and soon afterwards he acknowledged the lordship of King Alfred the Great of Wessex. This alliance was cemented by the marriage of Æthelred to Alfred's daughter Æthelflæd.

It allied with the Mercian kingdom in the post Roman era, to stabilise and control a central (Marches) area key to dominance over central Proto-England to the east and the south Welsh kingdom of Deheubarth to the west. It was conquered and pacified by the Armorican Normans between 1088 and 1095, though it remained Welsh in character. It was transformed into the Lordship of Brecknock and later formed the southern and larger part of the historic county of Brecknockshire. To its south was the Kingdom of Morgannwg.

It existed from the end of Roman rule in Britain in about the 5th century until the Norman invasion of Wales in the 11th century. Along with its neighbour Glywyssing, it seems to have had a great deal of cultural continuity with the earlier Silures, keeping their own courts and diocese separate from the rest of Wales until their conquest by Gruffydd ap Llywelyn. Although it recovered its independence after his death in 1063, Gwent was the first of the Welsh kingdoms to be overrun following the Norman conquest.
Glywysing was, from the sub-Roman period to the Early Middle Ages, a petty kingdom in south-east Wales. Its people were descended from the Iron Age tribe of the Silures, and frequently in union with Gwent, merging to form Morgannwg.

Cyfeilliog or Cyfeiliog ; probably died 927) was a bishop in south-east Wales, but the location and extent of his diocese is uncertain. He is recorded in charters dating from the mid-880s to the early tenth century, and in 914 he was captured by the Vikings and ransomed by Edward the Elder, King of the Anglo-Saxons, for 40 pounds of silver. Edward's assistance is regarded by historians as evidence that he was overlord of the south-east Welsh kingdoms. Cyfeilliog is probably the author of a cryptogram in the ninth-century collection of poetry known as the Juvencus Manuscript. The cryptogram would have required knowledge of Latin and Greek. The twelfth-century Book of Llandaff records his death in 927, but some historians are sceptical as they think that this date is late for a bishop active in the 880s.
