Æthelwold of Winchester was a tenth-century bishop and a central figure in the monastic reform movement in Anglo-Saxon England. Born in Winchester to noble parents, he served at the court of King Athelstan before becoming the abbot of Abingdon. He later served as the Bishop of Winchester from 963 until his death in 984. A staunch advocate for the Benedictine Rule, he worked to replace secular clergy with monks, often using forceful methods to achieve these religious transformations. He was also a significant political advisor to the English monarchy.
