This work investigates the political, social, and economic evolution of Britain under Roman occupation from the initial invasions to the eventual withdrawal of imperial forces. Sheppard Frere, a distinguished archaeologist and historian, utilizes a synthesis of literary evidence from classical authors and extensive archaeological data to reconstruct the administrative and cultural landscape of the province. The text argues that Romanization was a complex, multi-layered process that fundamentally altered the indigenous British social structure.

Historians and archaeologists frequently cite this work as a foundational text for understanding the Roman period in Britain due to its rigorous integration of material culture and textual sources.
