The vast empire created by the Romans remains one of the outstanding achievements of history. This text assesses the impact of the invasion of AD 43 on Iron-Age Britain and surveys the effect of Roman culture on this remote province up to and beyond the end of the military occupation. The process of Romanisation in town and country, in the arts, architecture and religion, is not, however, viewed in isolation, but in terms of Britain's place in the empire as a whole. This study, written by authors with an experience of the Romano-British collections of The British Museum, provides a synthesis of this important period.
