Gallienus's Decree Bannning Senators From Military Posts

Gallienus did not ban senators from serving in the army. Instead he turned to career military men who would go on to return empire to former glory. The rank of legate, that is, the leader of a single legion, was rebranded as the legatus aquitus. Gallienus also introduced a subtle shift in the way that provinces were governed which further calcified the division between civilian and military leadership.
