Copsi's rule lasted a mere five weeks, at which time he was murdered by Osulf, son of Eadulf III of the ancient Bernician family —which had historically governed the area from Bamburgh, at Newburn-upon-Tyne.
He was the last of the ancient Bernician line of earls to rule before his son Osulf usurped the Northumbrian earldom in 1067.
