'Aethelric' was the fourth known king of the
Kingdom of Bernicia which he ruled from
568 to
572. Aethelric was the father of
Æthelfrith, who was the first monarch to rule both Bernicia and
Deira, the two constituent parts of what came to be considered
Northumbria.
Aethelric was one of the sons born to
Ida of Bernicia, founder of the kingdom. Nothing is known for certain of Aethelric's life and reign. The earliest authorities differ widely on the order and the regnal years of the kings between the death of Ida and the beginning of Æthelfrith's rule in
592/
593.
