“The dramatic story of the soldiers at the heart of the Roman empire . . . traces the history of the praetorians and the emperors they served.”—Adrian Goldsworthy, author of Philip and Alexander: Kings and Conquerors

Founded by Augustus around 27 B.C., the elite Praetorian Guard was tasked with the protection of the emperor and his family. As the centuries unfolded, however, Praetorian soldiers served not only as protectors and enforcers but also as powerful political players. Fiercely loyal to some emperors, they vied with others and ruthlessly toppled those who displeased them, including Caligula, Nero, Pertinax, and many more. Guy de la Bédoyère provides a compelling first full narrative history of the Praetorians, whose dangerous ambitions ceased only when Constantine permanently disbanded them.

de la Bédoyère introduces Praetorians of all echelons, from prefects and messengers to artillery experts and executioners. He explores the delicate position of emperors for whom prestige and guile were the only defenses against bodyguards hungry for power. Folding fascinating details into a broad assessment of the Praetorian era, the author sheds new light on the wielding of power in the greatest of the ancient world’s empires.

“Any future researcher into the subject will certainly begin here.”—The Times (London)

“A lively and up-to-date history of the Praetorian Guard, the anti-coup divisions of the Roman emperors from Augustus to Constantine. De la Bédoyère tells their story with clarity and panache, and his book can be most warmly recommended both to aspiring tyrants and the ordinary armchair historian.”—The Sunday Times

“Fast paced and engaging.”—The Sunday Telegraph

“A definitive and highly readable account.”—Tom Holland, author of Rubicon: The Last Years of the Roman Republic
