 (early Empire, 30BC - 284AD) legions, for which there exists substantial literary, epigraphic and archaeological evidence.

Until the first century BC, Republican legions were temporary citizen levies, raised for specific campaigns and disbanded after them. By the early first century BC, legions were mixed volunteer/conscript units. Legions became standing units, which could remain intact long after a particular campaign was finished. Large numbers of new legions were raised by rival warlords for the civil wars of the period 49-30 BC.

However, when Augustus became sole ruler in 30 BC, he disbanded about half the over 50 legions then in existence. The remaining 28 legions became the core of the early Imperial army, most lasting over three centuries. Augustus and his immediate successors transformed legions into permanent units, staffed by entirely career soldiers on standard 25-year terms.

 (late Empire, 284 - 476) legions were also professional, but are little understood due to scarcer evidence than for the Principate.

This was the result of the military reforms of Emperors Diocletian

Gaius Marius
Gaius Marius

Gaius Marius was a Roman Republic general and politician elected consul an unprecedented seven times during his career. He was also noted for his dramatic Marian Reforms of Roman legion, authorizing recruitment of landless citizens and reorganizing the structure of the legions into separate Cohort ....
' reforms transformed legions into standing units, which could remain in being for several years, or even decades. This became necessary to garrison the Republic's now far-flung territories. Legionaries started large-scale recruiting of volunteer soldiers enlisted for a minimum term of six years and a fixed salary, although conscription was still practised. The property requirements, already much reduced, seem to have been abolished by Marius, so that the bulk of recruits were henceforth from the landless proletariat, who would be most attracted to the paid employment offered by the legions.

In the last century of the Republic, proconsuls governing frontier provinces became increasingly powerful. Their command of standing legions in distant and arduous military campaigns resulted in the allegiance of those units transferring from the Roman state to themselves. These imperatores (lit: victorious generals, from the title imperator

 and Octavian (later Augustus, the first Emperor himself. In this context, the imperatores raised many legions that were not authorised by the Senate, sometimes having to use their own resources (generally extorted from the provinces they controlled). As civil wars were resolved, many of these "private" units would be disbanded, only for more to be raised to fight the next civil war. By the time Augustus emerged as sole ruler in 30BC, over 50 legions were in existence, many of which were disbanded.

The legions included in the following list had a long enough history to be somehow remarkable. Most of them were levied by Julius Caesar and later included into Octavian's army, some of them were levied by Mark Antony.

TABLE LEGEND

  • Legion number & title
The numbering of the legions is confusing. Several legions shared the same number with others. Augustus numbered the legions he founded himself from I, but also inherited numbers from his predecessors. Each emperor normally numbered the legions he raised himself starting from I . However, even this practice was not consistently followed. For example, Vespasian
Vespasian

Titus Flavius Vespasianus, commonly known as Vespasian , was a Roman Emperor who reigned from 69 A.D. until his death in 79 A.D. Vespasian was the founder of the short lived Flavian dynasty, which ruled the Roman Empire between 69 A.D....

Born Marcus Ulpius Traianus into a nonpatrician family in the Hispania Baetica province , Trajan rose to prominence during the reign of emperor Domitian, serving as a general in the Roman army along the Limes G...
's first legion was numbered XXX because there were 29 other legions in existence at the time it was raised; but the second Trajanic legion was given the sequential number II. XVII, XVIII and XIX, the numbers of the legions annihilated in the Teutoberg Forest, were never used again. (These three legions are without titles, suggesting that in disgrace their titles may have been deliberately fogotten or left unmentioned.) As a result of this somewhat chaotic evolution, the legion's title became necessary to distinguish between legions with the same number.

Legions often carried several titles, awarded after successive campaigns, normally by the ruling Emperor e.g. XII Fulminata was also awarded: paterna (fatherly), victrix (victorious), antiqua (venerable), certa constans (reliable, steadfast) and Galliena (Gallienus
Gallienus

Publius Licinius Egnatius Gallienus ruled the Roman Empire as co-emperor with his father Valerian from 253 to 260, and then as the sole Roman Emperor from 260 to 268....
 '). Pia fidelis (dutiful, loyal), fidelis constans and others were titles awarded to several legions, sometimes several times to the same legion. Only the most established, commonly used titles are displayed on this table.

The geographical titles indicate
(a) the country a legion was originally recruited e.g. Italica = from Italy or
(b) peoples the legion has vanquished e.g.Parthica = victorious over the Parthians
Legions bearing the personal name of an emperor, or of his gens (clan) (e.g. Augusta, Flavia) were either founded by that Emperor or awarded the name as a mark of special favour.

The title GEMINA probably means the legion is twinned with another, or has been split from another to form a new legion. Alternatively, it may mean the legion is dedicated to the Gemini (Twins) Romulus and Remus

  • Main legionary base
This shows the castra (base) where the legion spent the longest period during the Principate. Legions often shared the same base with other legions. Detachments of legions were often seconded for lengthy periods to other bases and provinces, as operational needs demanded.

  • Emblem
Legions often sported more than one emblem at the same time, and occasionally changed them. Legions raised by Caesar mostly carried a bull emblem originally; those of Augustus mostly a Capricorn

  • Date disbanded
For legions that are documented into the fourth century and beyond, we do not know when or how they were terminated. For legions disappearing from the record before 284, the reason (certain or likely) is given as:
XX = annihilated in battle
DD = disbanded in disgrace
UF = unknown fate

, the structured border fortifications, and were formed by professional soldiers with an inferior training.

The field units were to stay well behind the border, and to move quickly where they were needed, with both offensive and defensive roles. Field units were formed by elite soldiers with high-level training and weapons. They were further divided into:
