Eadberht was king of Northumbria from 737 or 738 to 758. He was the brother of Ecgbert, Archbishop of York. His reign is seen as a return to the imperial ambitions of seventh-century Northumbria and may represent a period of economic prosperity. He faced internal opposition from rival dynasties and at least two actual or potential rivals were killed during his reign. In 758 he abdicated in favour of his son Oswulf and became a monk at York.
