English Benedictine Reform in the context of New Minster, Winchester

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 Cluniac Reforms (also called the Benedictine Reform) were a series of changes within medieval monasticism in the Western Church focused on restoring the traditional monastic life, encouraging art, and caring for the poor. The movement began within the Benedictine order at Cluny Abbey, founded in 910 by William I, Duke of Aquitaine (875–918). The reforms were largely carried out by Saint Odo (c. 878 – 942) and spread throughout France (Burgundy, Provence, Auvergne, Poitou), into England (the English Benedictine Reform), and through much of Italy, northern Portugal and Spain.

Æthelwold of Winchester (also Aethelwold and Ethelwold, 904/9 – 984) was Bishop of Winchester from 963 to 984 and one of the leaders of the tenth-century monastic reform movement in Anglo-Saxon England.

Monastic life had declined to a low ebb in England in the ninth century, partly because of the ravages caused by Viking attacks, and partly because of a preference for secular clergy, who were cheaper and were thought to serve the spiritual needs of the laity better. Kings from Alfred the Great onwards took an interest in the Benedictine rule, but it was only in the middle of the tenth century that kings became ready to commit substantial funds to its support. Æthelwold became the leading propagandist for the monastic reform movement, although he made enemies by his ruthless methods, and he was more extreme in his opposition to secular clergy than his fellow reformers, Saint Dunstan and Oswald of Worcester. He is nevertheless recognised as a key figure in the reform movement, who also made a major contribution to the revival of learning and the arts. He was an important political figure, backing Æthelred the Unready against Edward the Martyr, and playing a major advisory role during Æthelred's minority.

Ælfhere (died in 983) was Ealdorman of Mercia. His family, along with those of Æthelstan Half-King and Æthelstan Rota, rose to greatness in the middle third of the 10th century. In the reign of Edward the Martyr, Ælfhere was a leader of the anti-monastic reaction and an ally of Edward's stepmother Queen Dowager Ælfthryth. After the killing of Edward by Ælfthryth's servants in 978, Ælfhere supported the new king, Ælfthryth's son Æthelred the Unready, and was the leading nobleman in the Kingdom of England until his death in 983.

The reform of a religious order is the return of the order from a mitigated or relaxed observance to the rigour of its primitive rule. Example include the Cluniac Reforms and the English Benedictine Reform.

Eric John (1922–2000) was a reader in history at the University of Manchester and a specialist in Anglo-Saxon history. He was described by James Campbell as "one of the most distinguished and provocative of Anglo-Saxonists". D. H. Farmer described his studies of the English Benedictine Reform, mainly in pages 154-264 of Orbis Britanniae, as "both stimulating and provocative; even those who cannot assent to all his conclusions recognise that he has brought a new dimension to the study of the reform".
