Almost the entire period between the accessions of Vespasian and Septimius Severus was dominated by military affairs in Britain. At the beginning of the period of the survey the cities of Britain were recovering from the aftermath of the Boudican rebellion. The three certainly known to have been destroyed, Colchester, London and Verulamium, have each produced evidence of slow recovery with delays in their redevelopment of a decade or more. With one or two exceptions the area where one can identify early villa development is in the south-east. Elsewhere the aristocracy, whether native or immigrant and presumed to be associated with the urban developments of the Flavian period and the second century, is much less visible architecturally in the countryside. By the end of the second century the military and civilian structures of Roman Britain were firmly established. After the decision to abandon the Antonine Wall, the frontier arrangements in the north remained essentially unchanged.
