266 CE
The senators are practically excluded from the army under Gallienus.
The equites, members of the Roman equestrian order, receive the majority of commands and of provincial governorships; the composition of the army is modified by the creation of new army corps and especially of a strong cavalry, which is placed under the command of a single leader and charged with closing the breaches that the barbarians are opening along the frontiers.
