Die Legio XIV wurde 41 v. Chr. von Augustus aufgestellt. Sie war seit 9 n. Chr. in Moguntiacum (Mainz) stationiert und kämpfte später unter Claudius in Britannien, wo sie 60 oder 61 n. Chr. half, Boudicca niederzuwerfen. Später war die Legion u. a. in Vindobona (Wien) und Carnuntum stationiert. Sie war an den Usurpationen des Saturninus und Regalianus beteiligt.

Legio XIV Gemina Martia Victrix was a legion of the Roman Empire, levied by Octavian after 41 BC. The cognomen Gemina (twin in Latin) suggests that the legion resulted from fusion of two previous ones, one of them possibly being the Fourteenth legion that fought in the Battle of Alesia. Martia Victrix (martial victory) were cognomens added by Nero following the victory over Boudica. The emblem of the legion was the Capricorn, as with many of the legions levied by Augustus.
Invasion of Britain
Stationed in Moguntiacum, Germania Superior, since AD 9, XIIII Gemina Martia Victrix was one of four legions used by Aulus Plautius and Claudius in the Roman invasion of Britain in 43, and took part in the defeat of Boudicca in 60 or 61. In 68 it was stationed in Gallia Narbonensis.
Rebellion on the Rhine
In 89 the governor of Germania Superior, Lucius Antonius Saturninus, rebelled against Domitian, with the support of the XIVth and of the XXI Rapax, but the revolt was suppressed.
Pannonian defense
When the XXIst legion was lost, in 92, XIIII Gemina was sent in Pannonia to substitute it, camping in Vindobona (Vienna). After a war with the Sarmatians and Trajan's Dacian Wars (101-106), the legion was moved to Carnuntum, where it stayed for three centuries. Some subunits of Fourteenth fought in the wars against the Mauri, under Antoninus Pius, and the legion participated to the Parthian campaign of Emperor Lucius Verus. During his war against the Marcomanni, Emperor Marcus Aurelius based his headquarters in Carnuntum.
In support of Septimius Severus
In 193, after the death of Pertinax, the commander of the Fourteenth, Septimius Severus, was acclaimed emperor by the Pannonian legions, and above all by his own. XIIII Gemina fought for its emperor in his march to Rome to attack usurper Didius Julianus (193), contributed to the defeat of the usurper Pescennius Niger (194), and probably fought in the Parthian campaign that ended with the sack of the capital of the empire, Ctesiphon (198).
In support of imperial candidates
In the turmoil following the defeat of Valerian, tXIIII Gemina supported usurper Regalianus against Emperor Gallienus (260), then Gallienus against Postumus of the Gallic empire (earning the title VI Pia VI Fidelis — "six times faithful, six times loyal"), and, after Gallienus death, Gallic Emperor Victorinus (269-271).
5th century
At the beginning of the 5th century, XIIII Gemina still stayed at Carnuntum. It probably dissolved with the collapse of the Danube frontier in 430s. The Notitia Dignitatum lists a Quartodecimani comitatensis unit under the Magister Militum per Thracias; it is possible that this unit is XIV Gemina.
