Although Arthur is often thought of as the King of England, the designation "England" (signifying "Angle-Land") for the country below Scotland and east of Wales was not used until after the Anglo-Saxon conquest in the sixth and seventh centuries. The first Celts to land in England are traditionally thought to have arrived c. 600 BC. England remained a Celtic stronghold until the Roman invasion, although even then the English Celts retained a fair degree of autonomy. Prior to this, the area now thought of as "England" was called Logres. (In the Prose Brut, the name is derived from "Engist", the Saxon leader.)

After the departure of the Romans, the country laid open for invasion by the Anglo-Saxons, who pushed the Celts further and further west until they were confined to Cornwall in the south-west or in Wales. Very little of the Celtic way of life in England has survived, except in these small areas. The "country of Logris ... that is for to say the country of England", excluding Scotland, Wales, and Cornwall.

Sub-kingdom include Arroy, Avilion, Cameliard, the Delectable Isle, King Aman's Land, Leicester, Listeneise, Malahaut, Nohaut, Northumberland, and Roestoc.

Since "England" was in general usage when a good part of the Arthurian romances were written, however, the name appears quite often, indicating all or some portion of Britain. Malory, for instance, uses "England" without reservation. Usually, it is named as Arthur’s kingdom, although there are some notable exceptions. In Wirnt von Grafenberg’s Wigalois, for instance, the King of England wages war on Arthur, whose kingdom is in Brittany. In the Middle-English Sir Tristrem and the Norse and Icelandic Tristan sagas, it is Mark’s kingdom.
