Later Roman Britain is viewed in a wide context to identify which developments are expressions of wider trends and which are more insular. Four major factors are considered. First, the withdrawal of the imperial presence from northern Gaul and Germany, in particular as it affected the society and economy of these regions, which had become increasingly militarized. Second, the disintegration of the economic formations of the wider West following the removal of the imperial system, especially the economic nexus promoted by the fiscal requirements of the state. Third, the continuing vitality of ‘traditional’ urbanism derived from imperial and senatorial models, expressive of a common aristocratic culture and very visible in southern Britain. Fourth, the changes to settlement and funerary archaeology in the fifth century as expressions of social and economic restructuring. Britain is considered in relation to all these developments, to try to combat over-insular perspectives.
