Was a first cousin of his predecessor Ceolwulf and a son of Eata, said to be a descendant of Ida. He was presumably chosen as a more effective battle-leader than Ceolwulf. His brother, Ecgberht, was archbishop of York from 734 to 766, and the closeness of their collaboration is indicated by the existence of a coin inscribed with both their names. Under Eadberht something of the glory and influence of Northumbria was restored. In 740, while he was campaigning against the Picts, his own territories were devastated by Aethelbald of Mercia. In 750 he was reported to have added the plain of Kyle in Ayrshire to his kingdom. He joined forces in 756 with the Picts in a successful campaign against the Britons of Strathclyde, capturing their capital at Dumbarton, but Symeon of Durham, without sufficient explanation, recorded that, within ten days, his army had been utterly destroyed. Two years later he became a monk at the monastery of St Peter at York, making over his throne to his son Oswulf. He died on 20 August 768 and was buried, with his brother, in York Minster.
