In this new edition Pat Southern examines the anarchic era of the soldier Emperors that preceded the crisis of AD 260, and the reigns of underrated and maligned Emperors such as Gallienus, Probus and Aurelian, whose determination and hard work reunited the Empire.

The successes and failures of these rulers, and the role of armies and civilians, are re-assessed in this revised and expanded edition of The Roman Empire from Severus to Constantine, which incorporates the latest thinking of modern scholars and has been extended to cover Constantine, whose reign transformed the Empire into a Christian state. This is a crucial volume for students of this fascinating period in Roman history.

Pat Southern studied Ancient History and Archaeology at the Universities of London and Newcastle upon Tyne. She is the author of numerous books on Roman history, including The Roman Cavalry (with Karen Dixon, Routledge 1997), The Late Roman Army (with Karen Dixon, Routledge 2000), Domitian - Tragic Tyrant (Routledge 1997) and Augustus (Routledge 1998, second edition 2014).
