This work investigates the administrative structure and personnel of Roman Britain from the initial conquest in AD 43 to the end of Roman rule in AD 409. Anthony R. Birley, a distinguished scholar of Roman history, utilizes a comprehensive prosopographical approach to map the careers of governors, legionary legates, and other high-ranking officials. By synthesizing literary, epigraphic, and numismatic evidence, the author reconstructs the bureaucratic framework that sustained imperial authority in the province. The text serves as a systematic analysis of how career structures evolved from the principate through the late empire.

Scholars and historians recognize this volume as a definitive reference for the study of Roman provincial administration. Readers frequently note the academic density of the prose and the meticulous nature of the biographical data provided.
