666 CE
Earconwald, Anglo-Saxon abbot, establishes the Benedictine abbeys, Chertsey Abbey (Surrey) for men and Barking Abbey (now in east London) for women. Emperor Constans II grants the request of Bishop Maurus of Ravenna, allowing the city to consecrate its bishop without approval from Rome (approximate date). Wilfrid returns to Great Britain, but is shipwrecked in Sussex. When he finally reaches Northumbria, he finds he has been deposed and is forced to retire to Ripon.
