Legio II Traiana Fortis, Trajan's strong legion, was a Roman legion levied by emperor Trajan in 105 AD, along with Legio XXX Ulpia Victrix, for the campaigns in Dacia. There are still records of the II Traiana Fortis in Egypt in the middle of the 5th century AD. The legion's emblem was the demi-god Hercules.
In 115 AD, Traiana Fortis was incorporated in the large army used for Trajan's Parthian Campaign. In 117, the legion was allocated in Judea, to insure peace after the rebellion that was just ending. In 125 they were sent to Egypt for the first time, to share camp in Alexandria with Legio XXII Deotariana. Between 132-136 AD they were again in Judea to deal with another revolt.
The history of II Traiana Fortis gives an example of the political role of the legions. In 194, Pescinnius Niger, governor of the province of Syria, rebelled, with the legion's support, among others. His rival was Septimius Severus who would become emperor. In the days before the final battle, the legion changed sides and vowed fidelity to Severus. This would prove to be decisive for Pescinnius defeat.
In the beginnings of the 3rd century, the legion is involved in Caracalla's campaign against Germanic tribes and receives the cognomen Germanica.
It is possible that IITraianaFortis was the first garrison of the new province, together with III Cyrenaica.
Half a century later, a subunit of IITraianaFortis made the same trip to the far west, when the emperor Gallienus (260-268) demanded its support against Postumus, the ruler of the independent Gallic Empire.
