Æthelwold of Winchester in the context of "Oswald of Worcester"

Edgar (or Eadgar), c. 944 – 8 July 975, also known as Edgar the Peacemaker and the Peaceable, was King of the English from 959 until his death in 975. He became king of all England on his brother Eadwig's death. He was the younger son of King Edmund I and his first wife, Ælfgifu. A detailed account of Edgar's reign is not possible, because only a few events were recorded by chroniclers and monastic writers, who were more interested in recording the activities of the leaders of the church.

Edgar mainly followed the political policies of his predecessors, but there were major changes in the religious sphere. The English Benedictine Reform, which he strongly supported, became a dominant religious and social force. It is seen by historians as a major achievement, and it was accompanied by a literary and artistic flowering, mainly associated with Æthelwold, Bishop of Winchester. Monasteries aggressively acquired estates from lay landowners with Edgar's assistance, leading to disorder when he died and former owners sought to recover their lost property, sometimes by force. Edgar's major administrative reform was the introduction of a standardised coinage in the early 970s to replace the previous decentralised system. He also issued legislative codes which mainly concentrated on improving procedures for enforcement of the law.

Edward the Martyr (c. 962 – 18 March 978) was King of the English from 8 July 975 until he was killed in 978. He was the eldest son of King Edgar (r. 959–975). On Edgar's death, the succession to the throne was contested between Edward's supporters and those of his younger half-brother, the future King Æthelred the Unready. As they were both children, it is unlikely that they played an active role in the dispute, which was probably between rival family alliances. Edward's principal supporters were Dunstan, Archbishop of Canterbury, and Æthelwine, Ealdorman of East Anglia, while Æthelred was backed by his mother, Queen Ælfthryth and her friend Æthelwold, Bishop of Winchester. The dispute was quickly settled. Edward was chosen as king and Æthelred received the lands traditionally allocated to the king's eldest son in compensation.

Edgar had been a strong and overbearing king and a supporter of the monastic reform movement. He had forced the lay nobility and secular clergy to surrender land and sell it at low prices to the monasteries. Æthelwold had been the most active and ruthless in seizing land for his monasteries with Edgar's assistance. The nobles took advantage of Edgar's death to get their lands back, mainly by legal actions but sometimes by force. The leading magnates were split into two factions, the supporters of Ælfhere, Ealdorman of Mercia, and Æthelwine, who both seized some monastic lands which they believed belonged to them, but also estates claimed by their rivals. The disputes never led to warfare.

The English Benedictine Reform or Monastic Reform of the English church in the late tenth century was a religious and intellectual movement in the later Anglo-Saxon period. In the mid-tenth century almost all monasteries were staffed by secular clergy, who were often married. The reformers sought to replace them with celibate contemplative monks following the Rule of Saint Benedict. The movement was inspired by Continental monastic reforms, and the leading figures were Dunstan, Archbishop of Canterbury, Æthelwold, Bishop of Winchester, and Oswald, Archbishop of York.

In seventh- and eighth-century England, most monasteries were Benedictine, but in the ninth century learning and monasticism declined severely. Alfred the Great (871–899) deplored the decline and started to reverse it. The court of Æthelstan (924–939), the first king of the whole of England, was cosmopolitan, and future reformers such as Dunstan and Æthelwold learned from Continental exponents of Benedictine monasticism. The English movement became dominant under King Edgar (959–975), who supported the expulsion of secular clergy from monasteries and cathedral chapters, and their replacement by monks. The reformers had close relations with the Crown, furthering its interests and depending on its support. The movement was confined to southern England and the Midlands, as the Crown was not strong enough in northern England to confiscate property from local elites there to establish Benedictine foundations. The movement declined after the deaths of its leading exponents at the end of the tenth century.

Ælfric of Eynsham (Old English: Ælfrīc; Latin: Alfricus, Elphricus; c. 955 – c. 1010) was an English abbot and a student of Æthelwold of Winchester, and a consummate, prolific writer in Old English of hagiography, homilies, biblical commentaries, and other genres of Christian literature. He is also known variously as Ælfric the Grammarian (Alfricus Grammaticus), Ælfric of Cerne, and Ælfric the Homilist. In the view of Peter Hunter Blair, he was "a man comparable both in the quantity of his writings and in the quality of his mind even with Bede himself." According to Claudio Leonardi, he "represented the highest pinnacle of Benedictine reform and Anglo-Saxon literature".

The New Minster Charter is an Anglo-Saxon illuminated manuscript that was likely composed by Bishop Æthelwold and presented to the New Minster in Winchester by King Edgar in the year 966 AD to commemorate the Benedictine Reform. It is now part of the British Library's collection.

The Bishop of Ely is the ordinary of the Church of England Diocese of Ely in the Province of Canterbury. The diocese roughly covers the county of Cambridgeshire (with the exception of the Soke of Peterborough), together with a section of north-west Norfolk and has its episcopal see in the City of Ely, Isle of Ely in Cambridgeshire, where the seat is located at the Cathedral Church of the Holy Trinity. The diocesan bishops resided at the Bishop's Palace, Ely until 1941; they now reside in Bishop's House, the former cathedral deanery.

The roots of the Diocese of Ely are ancient and the area of Ely was part of the patrimony of Saint Etheldreda. Prior to the elevation of Ely Cathedral as the seat of the diocese, it existed as first as a convent of religious sisters and later as a monastery. It was led by first by an abbess and later by an abbot. The convent was founded in the city in 673. After St Etheldreda's death in 679 she was buried outside the church. Her remains were later translated inside, the foundress being commemorated as a great Anglican saint. The monastery, and much of the city of Ely, were destroyed in the Danish invasions that began in 869 or 870. A new Benedictine monastery was built and endowed on the site by Saint Athelwold, Bishop of Winchester, in 970, in a wave of monastic refoundations which also included Peterborough and Ramsey. In the Domesday Book in 1086, the Abbot of Ely is referenced as a landholder of Foxehola. The abbey became a cathedral in 1109, after a new Diocese of Ely was created out of land taken from the Diocese of Lincoln. From that time the line of bishops begins.
