Legio V Macedonica

Legio V Macedonica (the Fifth Macedonian Legion) was a Roman legion. It was established in 43 BC by consulGaius Vibius Pansa Caetronianus and Gaius Julius Caesar Octavianus (later known as the EmperorAugustus), and was based in the Balkan provinces of Macedonia, Moesia and Dacia. In the Notitia Dignitatum records from beginning of the fifth century, the legion was still stationed in Dacia, with detachments stationed in the east and Egypt.

The last known evidence shows the legion, or detachments from it, stationed in Egypt in the seventh century one or two years before the Islamic conquest of Egypt. It is often assumed that the legion fought in this war and was destroyed, although it is uncertain whether detachments or the whole legion were in Egypt, and there is no further evidence of the legion's eventual fate. Regardless, the duration in which the legion is known to have been extant—from 43 BC to at least c. AD 635—makes it one of the longest-serving Roman legions; possibly, the single most long-lived of all.

Its symbol was the bull, but the eagle was used as well.
