Traditional studies of Roman frontiers have focussed on the internal workings of the Roman military or have stressed the continuity of Iron Age society. Such approaches have downplayed or avoided discussions of social interaction. This is in contrast to developments in wider frontier studies in archaeology. This thesis examines pluralistic social settings in the northern frontier area of Roman Britain, addressing the subject in a multiscalar, diachronic, and holistic manner, which incorporates advances made in both Iron Age archaeology and Roman studies.
