Deheubarth was a regional name for the realms of south Wales, particularly as opposed to Gwynedd. It is now used as a shorthand for the various realms united under the House of Dinefwr, but that Deheubarth itself was not considered a proper kingdom on the model of Gwynedd, Powys, or Dyfed is shown by its rendering in Latin as dextralis pars or as Britonnes dexterales and not as a named land. In the oldest British writers, Deheubarth was used for all of modern Wales to distinguish it from Hen Ogledd, the northern lands whence Cunedda originated.

North Wales is a region of Wales, encompassing its northernmost areas. It borders mid Wales to the south, England to the east, and the Irish Sea to the north and west. The area is highly mountainous and rural, with Snowdonia National Park and the Clwydian Range and Dee Valley, known for its mountains, waterfalls and trails, wholly within the region. Its population is concentrated in the north-east and northern coastal areas, with significant Welsh-speaking populations in its western and rural areas. North Wales is imprecisely defined, lacking any exact definition or administrative structure. It is commonly defined administratively as its six most northern principal areas, but other definitions exist, with Montgomeryshire historically considered to be part of the region.

The Kingdom of Dyfed, one of several Welsh petty kingdoms that emerged in 5th-century sub-Roman Britain in southwest Wales, was based on the former territory of the Demetae. The medieval Irish narrative, The Expulsion of the Déisi, attributing the kingdom's founding to Eochaid, son of Artchorp, being forced across the Irish sea, in the 5th century; his descendants founding the line of the kings of Dyfed, down to "Tualodor mac Rígin".

The Battle of the Conwy took place in 881 between King Anarawd and his brothers of the northern Welsh Kingdom of Gwynedd and a Mercian army almost certainly led by Æthelred, Lord of the Mercians. The Welsh were victorious, and the battle ended the traditional hegemony of Mercia over north Wales and contributed to Æthelred's decision to accept the lordship of King Alfred the Great of Wessex. This united the Anglo-Saxons who were not living under Viking rule under Alfred, and was a step towards the creation of the Kingdom of England. Anarawd allied himself with the Vikings shortly after the battle, but he then abandoned this alliance to follow Æthelred in accepting Alfred's lordship.
