Dunstan in the context of "Osbern of Canterbury"

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.

Eadwig (also Edwy or Eadwig All-Fair, c. 940 – 1 October 959) was King of England from 23 November 955 until his death in 959. He was the elder son of Edmund I and his first wife Ælfgifu, who died in 944. Eadwig and his brother Edgar were young children when their father was killed trying to rescue his seneschal from attack by an outlawed thief on 26 May 946. As Edmund's sons were too young to rule he was succeeded by his brother Eadred, who suffered from ill health and died unmarried in his early 30s.

Eadwig became king in 955 aged about fifteen and was no more than twenty when he died in 959. He clashed at the beginning of his reign with Dunstan, the powerful Abbot of Glastonbury and future Archbishop of Canterbury, and exiled him to Flanders. He later came to be seen as an enemy of monasteries, but most historians think that this reputation is unfair. In 956, he issued more than sixty charters transferring land, a yearly total unmatched by any other European king before the twelfth century, and this is seen by some historians as either an attempt to buy support or rewarding his favourites at the expense of the powerful old guard of the previous reign.

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.

Oswald of Worcester (died 29 February 992) was Archbishop of York from 972 to his death in 992. He was of Danish ancestry, but brought up by his uncle, Oda of Canterbury, who sent him to France to the abbey of Fleury to become a monk. After a number of years at Fleury, Oswald returned to England at the request of his uncle, who died before Oswald returned. With his uncle's death, Oswald needed a patron and turned to another kinsman, Oskytel, who had recently become Archbishop of York. His activity for Oskytel attracted the notice of Archbishop Dunstan, who had Oswald consecrated as Bishop of Worcester in 961. In 972, Oswald was promoted to the see of York, although he continued to hold Worcester also.

As bishop and archbishop, Oswald was a supporter and one of the leading promoters (together with Æthelwold) of Dunstan's reforms of the church, including monastic reforms. Oswald founded a number of monasteries, including Ramsey Abbey, and reformed another seven, including Winchcombe in Gloucestershire and Pershore and Evesham in Worcestershire. Oswald also switched the cathedral chapter of Worcester from secular clergy to monks. While archbishop, he brought the scholar Abbo of Fleury to teach, and he spent two years in England, mostly at Ramsey. Oswald died in 992, while washing the feet of the poor. A hagiographical life was written shortly after his death, and he was quickly hailed as a saint.
