Diocletian and Constantine were the greatest of the Late Roman emperors,
and their era marks the climax of the legionary system. Under
Constantine's successors the legions were reduced in size and
increasingly sidelined in favour of new units of elite auxilia, but
between AD 284 and 337 the legions reigned supreme. The legionaries
defeated all-comers and spearheaded a stunning Roman revival that
humbled the Persian Empire and reduced the mighty Goths and Sarmatians
to the status of vassals. This title details the equipment, background,
training and combat experience of the men from all parts of the empire
who made up the backbone of Rome's legions in this pivotal period.
