A centurion was promoted for being an exemplary soldier and was then expected to become a strict commander of his subordinates, to lead his troops by example, and coordinate his century's actions. They were also responsible for handling logistics and supplies, as well as any discipline that was required. In a

, the centurions commanded a ''
centuria'' or "century". During the Mid-Republic these centuries were grouped in pairs to make up a
maniple, each century consisting of 30–60 men. After the so-called "
Marian reforms", a century was typically composed of around 80 men, with six such centuries forming a
cohort. Later, generals and emperors further manipulated these numbers with double and half-strength units.

Gaius Julius Caesar (12 or 13 July 100 BC – 15 March 44 BC) was a Roman general and statesman. A member of the First Triumvirate, Caesar led the Roman armies in the Gallic Wars before defeating his political rival Pompey in Caesar's civil wa ...
, for instance, made the first cohort of five double strength centuries.
During the Imperial era, centurions gradually rose in seniority in their cohort, commanding centuries with higher precedence, until commanding the senior century and therefore the whole cohort. The best centurions were then promoted to the first cohort and known as the ''primi ordines'', commanding one of the cohort's five centuries and taking on a staff role. The most senior centurion of the legion was the ''primus pilus'' who commanded the first century of the first cohort. All centurions, however senior, had their own allocated century. There was little difference between the ranks of centurions except for the ''primus pilus'', who also participated in war councils. The ''primus pilus'' was so called because his own century was the ''first file'' of the first (rightmost) cohort. Only eight officers in a fully officered legion outranked the ''primus pilus'': the
legate (''legatus legionis''), commanding the legion; the senior tribune (''

''), second-in-command of the legion; the camp prefect (''

legionary. Veteran legionaries often worked as tenants of their former centurions. Centurions could be elected, appointed by the

Centurions were held personally responsible for the training and discipline of the legionaries under their command, and they had a reputation for dealing out harsh punishment.
Tacitus
Publius Cornelius Tacitus, known simply as Tacitus ( , ; – ), was a Roman historian and politician. Tacitus is widely regarded as one of the greatest Roman historians by modern scholars.
Tacitus’ two major historical works, ''Annals'' ( ...
tells a story in ''
The Annals'' of a centurion known as "Cedo Alteram", which roughly translates to "Fetch Me Another". "The mutinous soldiers thrust out the tribunes and the camp-prefect; they plundered the baggage of the fugitives, and then killed a centurion, Lucilius, to whom, with soldier's humour, they had given the nickname 'Cedo Alteram', because when he had broken one
vine-stick across a soldier's back, he would call in a loud voice for another… and another...and another!" The vine-stick (''vitis'') was a symbol of the centurion's authority and the implement with which he meted out punishment.
Unlike legionaries, centurions carried their swords on their left side as a sign of distinction and carried the
pugio (dagger) on the right, as the sidearm. Centurions wore transverse crests on their helmets that would distinguish them from other legionaries. Centurions often had important social status and held powerful positions in society. They seem to have received their status according to their rank. On retirement, they could be eligible for employment as
lictors.
Seniority

Each century had a precedence within the cohort. Centurions' seniority within the cohort and legion depended on the position within the legion of the century they were in charge of, which often took their name from their centurion. Centurions began by leading junior centuries before being promoted to leading a more senior one. Promotion usually came with experience, or at least length of service, but many still never made it as far as leading a first cohort. Yet for centurions who showed, say, particularly conspicuous bravery during battle, there was the opportunity to be promoted several grades at once. For example, Julius Caesar's reward for a centurion who had greatly pleased him was to advance him eight grades.
[''The Legions of Rome'', Stephen Dando-Collins, pp40, Quercus (December 2010)]
The precedence during the times of the Republican
manipular legion had each centurio command a centuria of sixty men within a manipulus (maniple) of two centuriae which was commanded by the senior centurio. Their order in decreasing seniority but opposite battle order;
Of the centuriae of a manipulus of Triarii;
#Pilus Prior
#Pilus Posterior
Of the centuriae of a manipulus of Principes;
#Princeps Prior
#Princeps Posterior
Of the centuriae of a manipulus of Hastati;
#Hastatus Prior
#Hastatus Posterior
For the Imperial and late Republican legion (post 107 BC) the first centuria of every cohors was its senior, with the first cohors following suit for the entire legion. There were five centuriae in the first cohors as opposed to the normal number of six, with each centuria having twice the number of legionaries of a normal centuria.
The six centuriae of a normal cohors, were, in order of decreasing seniority;
# The rear triarii (rear third line)
# The forward triarii (forward third line)
# The rear principes (rear principal line)
# The forward principes (forward principal line)
# The rear hastati (rear spears)
# The forward hastati (forward spears)
The titles of the centuriae and thus their respective centuriones are remnants from the manipular system of the Republic. In order of decreasing seniority;
1st Cohors, Centuriones known as the Primi Ordines
#1st Centuria Primus Pilus
#2nd Centuria Princeps Prior
#3rd Centuria Princeps Posterior
#4th Centuria Hastatus Prior
#5th Centuria Hastatus Posterior
2nd Cohors
#1st Centuria Pilus Prior
#2nd Centuria Pilus Posterior
#3rd Centuria Princeps Prior
#4th Centuria Princeps Posterior
#5th Centuria Hastatus Prior
#6th Centuria Hastatus Posterior
and so on.
Note that the Primi Ordines of the first cohors were senior to every centurio except for their Primus Pilus and the Pili Priori of the other first centuries.
Qualities
According to a 5th century text on the Roman military, a centurion was required to have numerous elite traits:
Centurions had to be at least 30 years of age, literate (to read written orders), have letters of recommendation, and have at least several years of military service. As a commander, a centurion had to be able to maintain his troops’ morale in peace and inspire his men in battle.
