The purpose of this thesis is to determine whether the Roman administrative towns of Britain continued in their original Romanized form as seen in the second century AD, or were altered in their appearance and function in the fourth and fifth century, with a visible reduction in their urbanization and Romanization. It will be argued that British town life did change significantly. Major components of urbanization were disrupted with the public buildings disused or altered for other purposes, and the reduction or cessation of public services. A reduction in the population of the towns can be perceived in the eventual disuse of the extramural cemeteries and abandonment of substantial areas of settlement or possibly entire towns. The cause of this will be shown to be related to the towns' relationship with the imperial taxation and revenue system, and the accelerating pattern of British involvement in revolts and usurpations. / Graduate
