900-924: Edward the Elder & the Creation of England

Alfred the Great is succeeded by Edward (only called the Elder to distinguish him from a later King Edward) in 900, reigning until 924.  The first quarter of the tenth century is defined by the roll back of the Danes, the creation of a viable idea of England as island-wide and by what amounts to the progressive sanctification and 'orientalisation' by the Church of the Monarchy, seated in a national capital at Winchester.

The first test of the treaties made under Alfred was an attempt by the men of Kent in 902 to oust the Danes from East Anglia which failed, although the Danish ruler of the East Anglians, Eric, was killed at the Battle of the Holme. However, the Anglo-Saxons are now stronger and better organised than the Danes. The reconquest of the Danelaw starts in earnest from 910. The warrior princess Aethelflaed, Edward's sister and wife of the Ealdorman of Mercia, Aethelred, was no shrinking violet but took on the role of 'Lady of the Mercians' when her husband was killed in 911. She not only ruled her husband's domains but expanded them, seizing Derby in 917 and ruling until 920. Thanks to her and the Mercians' efforts, the Northern frontier of England was extended to the Dee-Wash line.

Meanwhile, Edward reconquered East Anglia and the rest of Southen England under Danish independent control in 918 and accepted the submission of the Welsh Kings of Dyfed and Gwynedd. By 919 the Viking Kingdom of Jorvik (York) under its new ruler Ragnald had also acknowledged the overlordship of Edward. By 920 Edward ruled as overlord all Southern Britain as far as the Forth-Clyde line, uniting the area (at least notionally) for the first time since the Romans. In 923 Edward even received the submission of the King of the Scots.  Alfred the Great is rightly regarded as 'Great' for having saved England existentially but the making of England as a sovereign entity that was more than just a large Wessex may be put down to his now less well known successor.

As for the sanctification process which helped to link the fortunes of the Anglo-Saxons as a people to their Kings as divinely sanctioned, this is exemplified  by the transfer of the claimed body of King Edmund of East Anglia (murdered in 870 by the Danes) to be buried with full rites at Beodricsworth (later Bury St. Edmunds).
