Mid-Imperial Romans
193-324 AD

By Nick Gaukroger

This army list covers Roman armies from the time of Septimus Severus to that of Constantine—and we have used the date of Constantines undisputed rule over the whole Empire. Septimus Severus recruited new legions and reorganised others, dismissing the Old Praetorian Guard and refounding it using loyal troops from the legions—so it is a good point in terms of characterising developments in the Roman military.
