Cause

Mercia had long maintained hegemony over north Wales, and tensions between the Welsh Kingdom of Gwynedd and Mercian authority came to a head in 881. King Anarawd and his brothers led Gwynedd forces to resist continued Mercian dominance over their region.

Event

The Battle of the Conwy was fought in 881 between the forces of King Anarawd of Gwynedd and a Mercian army almost certainly commanded by Æthelred, Lord of the Mercians. The Welsh emerged victorious, defeating the Mercian forces along the River Conwy.

Consequence

The Welsh victory broke the traditional Mercian hegemony over north Wales. Æthelred subsequently accepted the overlordship of King Alfred the Great of Wessex, uniting the Anglo-Saxons not under Viking rule. Anarawd briefly allied with Vikings before also accepting Alfred's lordship, marking a step toward the eventual formation of the Kingdom of England.
