Legio I Armeniaca-Armenian First Legion

"Legio Armeniaca" translates from Latin as "Armenian Legion" and "prima" as "first". The Armenian First Legion was one of the later-period Roman imperial legions. This Legion was mentioned in the late-antique text known as Notitia Dignitatum. It is most likely that the Armenian First Legion was formed in the 2nd or 3rd century AD, in the western part of the Kingdom, with the mission to protect the lands of Armenia from intrusion. It might first have been the garrison of Armenian lands which had been under the control of the Roman Empire. The Armenian First Legion took part in the ill-fated Persian campaign of the emperor Julianus Apostata in 363.
