Between AD 161 and 244 the Roman legions were involved in wars and battles on a scale not seen since the late Republic. Legions were destroyed in battle, disbanded for mutiny and rebellion and formed to wage wars of conquest and defence. This volume explores the experience of the imperial legionary, concentrating on Legio II Parthica. Raised by the emperor Septimus Severus in AD 193/4, it was based at Albanum near Rome and as the emperor's personal legion, became one of the most important units in the empire.
