The Battle

History & Significance

After Rhodri Mawr's death, his sons divided the kingdom but competed for supremacy. Welsh annals record fighting between the sons of Rhodri in this period. Anarawd of Gwynedd eventually emerged dominant, allied with Northumbria before switching to acknowledge Alfred the Great. The internal Welsh dynastic conflicts of this period weakened resistance to both Vikings and Saxons. Location estimated, as specific chronicle detail is lacking.
