In this captivating book, Gardner systematically reconnects the military frontier regions of Roman Britain with the ‘civil' areas of the province, challenging the traditional separation of these two fields of study. Gardner provides a detailed analysis of the peoples and cultures of the three frontier regions that delineated Britannia from its neighbours to the west, north and south-east. Theoretically adroit and data-rich, this book shapes the research agenda for the incorporation of Britain into the Roman Empire, from the time of Caesar's incursions to the end of Roman rule.
