Cnut's choice of thegnly advisors, put an end to the balanced relationship between monarchy and aristocracy so carefully forged by the West Saxon Kings. Edward became king in 1042, and given his upbringing might have been considered a Norman by those who lived across the English Channel. Following Cnut's reforms, excessive power was concentrated in the hands of the rival houses of Leofric of Mercia and Godwine of Wessex. Problems also came for Edward from the resentment caused by the king's introduction of Norman friends. A crisis arose in 1051 when Godwine defied the king's order to punish the men of Dover, who had resisted an attempt by Eustace of Boulogne to quarter his men on them by force. The support of Earl Leofric and Earl Siward enabled Edward to secure the outlawry of Godwine and his sons; and William of Normandy paid Edward a visit during which Edward may have promised William succession to the English throne, although this Norman claim may have been mere propaganda.

Some unpopular Normans were driven out, including Archbishop Robert, whose archbishopric was given to Stigand; this act supplied an excuse for the Papal support of William's cause.

By the time William of Normandy, sensing an opportunity, landed his invading force in 1066, the elite of Anglo-Saxon England had changed, although much of the culture and society had stayed the same. After the Norman Conquest Following the Norman conquest, many of the Anglo-Saxon nobility were either exiled or had joined the ranks of the peasantry. It has been estimated that only about 8% of the land was under Anglo-Saxon control by 1087. In 1086, only four major Anglo-Saxon landholders still held their lands. However, the survival of Anglo-Saxon heiresses was significantly greater. Many of the next generation of the nobility had English mothers and learnt to speak English at home. Some Anglo-Saxon nobles fled to Scotland, Ireland, and Scandinavia. The Byzantine Empire became a popular destination for many Anglo-Saxon soldiers, as it was in need of mercenaries. The Anglo-Saxons became the predominant element in the elite Varangian Guard, hitherto a largely
