Legio I Adiutrix


Legio I Adiutrix was a legion of the Roman army formed from veteran sailors after the death of Roman emperor Nero (r. 54-68 CE). During its long career, the legion accompanied Trajan (r. 98-117 CE) on his Dacian and Parthian campaigns, fought with Marcus Aurelius (r. 161-180 CE) in his German Wars, supported Septimius Severus in 193 CE, and was still active in the 5th century CE.
