antoninianus issued by
Gallienus in
260 to celebrate III ''Italica''. Note the stork, the symbol of the legion, on the obverse. The legion is called ''VI Pia VI Fidelis'', "six times faithful and six times loyal"
'Legio III ''Italica''' was a
Roman legion levied by
Marcus Aurelius around
165, for his campaign against the
Marcomanni tribe. The cognomen ''Italica'' suggests that recruits were originally from Italy. The legion was still active in Germania in the later
4th century. The legion's symbol was a
stork.
Together with legions
II ''Italica'' and
I ''Adiutrix'', III ''Italica'' legion was in the Danube provinces from its beginning, fighting the invasion of the
Raetia and
Noricum provinces by the Marcomanni. In
171 they built the camp ''Castra Regina'', modern
Regensburg, designed as a strongly defensive position like a
castle.
In the civil war of
193, this legion supported
Septimius Severus and helped him defeat his opponents first
Pertinax and
Didius Julianus, then
Pescennius Niger and
Clodius Albinus. Their loyalty was extended to Severus' successor, emperor
Caracalla, for whom they fought in
213 a campaign against the
Alamanni.
Since the cognomen ''III Italica Gordiana'' is recorded, the legion was somehow involved in Emperor
Gordian III campaign against the
Sassanid Empire in 243-244.
As a part of the powerful
Danubian army, III ''Italica'' took part in the frequent struggles for internal power in the
3rd century. The legion fought for
Gallienus against his rival
Postumus, so it was awarded with the ''VI Pia VI Fidelis'' and '''VII Pia VII Fidelis''' (seven times faithful and loyal) cognomen. III ''Italica'' main camp was still Regensburg, but they were included in the
273 campaign commanded by emperor
Aurelian against queen
Zenobia.

Shield pattern of the ''Tertiani Italica'', the
comitatensis legion derived from III ''Italica''.
The legion, a ''
comitatensis'' unit, is still mentioned by the sources in the late
4th century in the Danubian provinces.
