Boudicca: The Flame of Britannia explores one of the most consequential revolts against the Roman Empire and the queen who stood at its centre. In the first century CE, Rome extended its authority across Britain through military occupation, taxation, client kingdoms, and new systems of law. Following the death of Prasutagus, the fragile relationship between Rome and the Iceni collapsed, creating the conditions for a rebellion that swept through Camulodunum, Londinium, and Verulamium. Drawing upon Tacitus and Cassius Dio alongside archaeological evidence, this volume reconstructs the revolt within its political and material context. It examines the failure of client kingship, the abuse of Roman power, the mobilisation of indigenous resistance, and the brutal consequences for both provincial communities and the imperial administration. Rather than relying upon nationalist legend or Roman propaganda, the book presents Boudicca as a leader forged by the tensions of conquest, sovereignty, and irreversible cultural change. Part of the Powerful Female Rulers of Antiquity series, this volume examines a woman whose life shaped the political and cultural world of antiquity.
