Septimius Severus
In 193, II "Italica" marched into Rome with Septimius Severus, then fighting for power. The new emperor awarded them the title of "Fidelis" (loyal) to acknowledge their support. Later Septimius Severus would use II "Italica" against the rebellions of Pescennius Niger and Clodius Albinus, as well as in his Parthian campaigns.
