Abstract
Scholarly opinion on the character and timing of the end of Roman Britain remains deeply divided. The evidence presented by those favouring a ‘long chronology’ is seriously flawed. ‘Continuity’ or ‘survival’ of Roman Britain is claimed because early medieval activity is attested on some former Roman sites and some early medieval artefacts are of Roman type. But Roman Britain was part of a ‘world system’ with a distinctive and rich archaeological assemblage, and once terms are properly defined and material analysed quantitatively, the argument for fifth-century continuity collapses. The archaeological evidence shows that after a long process of decline beginning in the third century, Roman Britain had ended by c. A.D. 400.
