The reign of Burgred saw the virtual annihilation of Mercia, not at the hands of its old enemies, Wessex and Northumbria, but by the new menace of the Vikings. Burgred became king c.852 after Berhtwulf had been driven out by the Danes. He restored some temporary stability, begging the help of Aethelwulf of Wessex against the Welsh and then marrying his daughter, Aethelswith. In 867 he appealed once more to Wessex for help, this time against the Danes, but was forced to allow them to winter in Nottingham. For some years he held them in negotiation, but in c.874 they occupied Repton and drove him out of the kingdom. Burgred retired to Rome where he died soon after and was buried. His queen, Alfred's sister, died in 888 and was buried in Pavia.
