Brunanburh, battle of, 937. Brunanburh was the crowning military achievement of Athelstan's reign, which saw Wessex advances into Devon, south Wales, and the north. In 937 a formidable coalition attempted to hold him at bay. Constantine II of Scotland was joined by Owain of Strathclyde and Olaf Guthfrithsson from Dublin. In savage fighting, probably near the Humber, Athelstan and his brother Edmund prevailed.
