Their mandatory service was shorter in duration, for instance: 12 years with the Praetorians instead of 16 years in the legions starting year 13 BC, then carried to, respectively, 16 to 20 years in year 5 BC according to Tacitus.

This additional pay was the equivalent of several years of pay and was often repeated at important events of the empire or events that touched the imperial family: birthdays, births and marriages. Major monetary distributions or food subsidies renewed and compensated the fidelity of the Praetorians following each failed particular attempted plot (such as that of Messalina against Claudius in AD 48 or Pisco against Nero in AD 65). The Praetorians received substantially higher pay than other Roman soldiers in any of the legions, on a system known as , or by pay-and-a-half.

History

, '' praetors'' were either civic or military leaders. The praetorians were initially elite guards for military praetors, under the republic. The early Praetorian Guard differed greatly from that in later times, which came to be a vital force in the power politics of Rome. While Augustus understood the need to have a protector in the maelstrom of Rome, he was careful to uphold the democratic veneer of his regime. Thus, he allowed only nine cohorts to be formed, each originally consisting of 500 men. He then increased them to 1,000 men each but allowed three units to be kept on duty at any given time in the capital. A small number of detached cavalry units () of 30 men each were also organized. While they patrolled inconspicuously in the palace and major buildings, the others were stationed in the towns surrounding Rome. This system was not radically changed with the appointment by Augustus in 2 BC of two Praetorian prefects, Quintus Ostorius Scapula and Publius Salvius Aper, although organization and command were enhanced. Tacitus reports that the number of cohorts was increased to twelve from nine in AD 47. In AD 69 it was briefly increased to sixteen cohorts by

Every afternoon, the would receive the password from the emperor personally. The command of this cohort was assumed directly by the emperor and not by the Praetorian prefect. After the construction of the Praetorian camp in 23 BC, there was another similar serving tribune placed in the Praetorian camp accordingly. Their functions included, among many, the escort of the emperor and the members of the imperial family, and if necessary to act as a sort of anti-riot police. Certain Empresses exclusively commanded their own Praetorian Guard. According to Tacitus, in the year 23 BC, there were nine Praetorian cohorts (4500 men, the equivalent of a legion) to maintain peace in

, the number of cohorts increased to 12 during a brief period. This inscription referred to one man who was the tribune of two successive cohorts: the eleventh cohort, apparently at the end of the reign of Augustus, and the fourth at the beginning of the reign of Tiberius. According to Tacitus, there were only nine cohorts in 23 AD. The three urban cohorts, which were numbered consecutively after the Praetorian cohorts, were removed near the end of the reign of Augustus; it seemed probable that the last three Praetorian cohorts were simply renamed as urban cohorts. The first intervention of the Praetorians on a battlefield since the wars of the end of the Republic took place during the ''mutinies of Pannonia'' and the ''mutinies of Germania''. On the death of Augustus in AD 14, his successor Tiberius was confronted by mutinies in the two armies of the ''Rhine'' and ''Pannonia'', who were protesting about their conditions of service, in comparison with the Praetorians. The forces of Pannonia were dealt with by

. It was under Tiberius that Sejanus rose in power and was among the first prefects to exploit his position to pursue his own ambitions. He concentrated under his command all the Praetorian cohorts in the new camp. Sejanus held the title of prefect jointly with his father, under Augustus, but became sole prefect in AD 15. He used that position to render himself essential to the new emperor Tiberius, who was unable to persuade the Senate to share the responsibility of governing the Empire. Sejanus, however, alienated Drusus, son of Tiberius, and when the heir to the throne, Germanicus, died in AD 19, he was worried that Drusus would become the new emperor. Accordingly, he poisoned Drusus with the help of the latter's wife, and then immediately launched a ruthless elimination program against all competitors, persuading Tiberius to make him his heir apparent. He almost succeeded, but his plot was discovered and revealed in AD 31 and he was subsequently killed. Emperor Tiberius used for this purpose the which were not under the control of Sejanus.

Needing an emperor to justify their own existence, they brought him forth to the Praetorian camp and proclaimed him emperor. He is the first emperor proclaimed by the Praetorian Guard and compensated the guard with a prime bonus worth five years their salary. The Praetorians accompanied Emperor Claudius to Britain in 43 AD. When Claudius was poisoned, the Guard transferred their allegiance to

Participation in wars

While campaigning, the Praetorians were the equal of any formation in the Roman army. On the death of Augustus in 14 AD, his successor, Tiberius, was faced with mutinies among both the Rhine and Pannonian legions. According to Tacitus, the Pannonian forces were dealt with by Tiberius' son Drusus, accompanied by two Praetorian cohorts, the Praetorian cavalry and some of the German bodyguard. The German mutiny was put down by Tiberius' nephew and adopted son Germanicus, his intended heir, who then led the legions and detachments of the Guard in an invasion of Germany over the next two years.

Political role

The Praetorian Guard influenced and intervened in the imperial succession to name the new , which was a political decision that the unarmed Senate accepted, ratified, and proclaimed to the people of Rome. After the death of Sejanus, who was sacrificed for the (imperial gift) promised by Tiberius, the Praetorians became exceptionally ambitious in their influence upon the politics of the Roman Empire. Either by volition or for a price, the Praetorian Guard would assassinate an emperor, bully the Praetorian prefects, or attack the Roman populace. In AD 41, conspirators from the senatorial class and from the Guard killed Emperor Caligula, his wife, and their daughter. Afterwards, the Praetorians installed Caligula's uncle Claudius upon the imperial throne of Rome, and challenged the Senate to oppose the Praetorian decision. In AD 69, the

Organization


Leadership

Starting in the year 2 BC, the Praetorian prefect was the commanding officer of the Praetorian Guard (previously each cohort was independent and under the orders of a tribune of equestrian rank). This role (chief of all troops stationed in Rome), was in practice a key position of the Roman polity. From

onwards the Praetorian prefecture was always held by an equestrian of the order. (''Equestrians'' were traditionally that class of citizens who could equip themselves to serve in the Roman Army on horseback). From the year 2 BC, the cohorts were under the control of two prefectures; however cohorts continued to be organized independently, each commanded by a tribune. Tribunes had as immediate subordinates ordinary Centurions, all of equal rank except for the , the first and prime of all centurions of the Praetorian Cohorts, who commanded also the 300 , and with the exception of his second, the '' princeps castrorum''. From the second century the Praetorian prefect oversaw not only the Praetorian Cohorts but also the rest of the garrison of Rome, including the ("urban cohorts") and the , but not the ''Vigiles'' cohorts. Following the dissolution of the Praetorian Cohorts by the emperor Constantine after he defeated them at the Battle of the Milvian Bridge in 312, the role of the Praetorian prefect in the Empire became purely administrative, ruling large territories () comprising Roman

, initially of 500 men each. In order not to alienate the population of Rome, while conserving Republican civilian traditions, the Praetorians did not wear their armor while in the heart of the city. Instead they often wore a formal toga, which distinguished them from civilians but remained in a respectable civilian attire, the mark of a Roman citizen. Augustus, conscious of risking the only military force present in the city, often avoided concentrating them and imposed this dress code. From the reign of Tiberius, their camp was situated on the Quirinal Hill, outside Rome. In 26 AD, Sejanus, Praetorian prefect, and the favorite of emperor Tiberius, united the Urban Cohorts with nine Praetorian Cohorts, dispersed at that time throughout

Under Septimius Severus, recruitment evolved to authorize the inclusion of legionaries of the Roman army, as well as of the battle hardened ''Army of the Danube''. Severus stationed his supporters with him in Rome, and the Praetorian Guards remained loyal to his choices.

, and starting from Septimius Severus, men were transferred from the Urban Vigiles, Urban cohorts, and the various legions. This recent method and manner of recruitment at the corps of the legions became the normal procedure to recruit in the 3rd century after Septimius Severus dealt with the undisciplined Praetorians who assassinated Pertinax in 193, and replaced them with men from his own Danube legions. At that time, the Praetorians represented the best soldiers from the legions (principally from Illyria). They were a group of elite of soldiers starting from the 3rd century, and not a category of socially privileged soldiers (such as the Italians at the time of Augustus). The Italians formed the base of the recruitment of the , a new legion created and stationed in Italy. To be admitted to the Guard, a man had to be in good physical condition, have a

After two years, if he attracted the attention of his superiors by influence or merit, he could attain the post of (similar to corporal), perhaps as a commis (junior chief) at general headquarters or as a technician. This promotion exempted him from daily chores. After another two years he could be promoted to , with a double salary, in charge of delivering messages () or as an assistant centurion () or standard bearer () at the corps of the century; or, if literate and numerate, he could join the administrative staff of the prefect. Only a few soldiers could attain the rank of ; however those that did, during the course of their service, were designated by the emperor. This designation allowed them to be promoted to technical administrative posts, or instructors in Rome, or to a century in a legion, and accordingly extend their career. Certain could at the end of their career be promoted to Centurion in the Guard; this would be the peak of his career. Anyone ambitious for further promotion would need to transfer to a legion. The

Other leading paths towards the tribunate were possible, including service entirely made in the legions, attaining the rank of before departing to Rome. Nevertheless, all tribunes were combat veterans with extensive military experience. Each tribune served in Rome for one year, following which, a certain number of the men would retire. A few of them, ranking placement at the top of the hierarchy, could obtain a second term as and advance towards the superior echelons of the equestrian career, possibly becoming the Praetorian prefect. The majority of the prefects, however, were ordinary men of the equestrian rank by birth. The men who attained the command of the Guard following year 2 BC were equites with an elevated seniority, classifying right behind the prefect of Egypt. Starting from Vespasian, whose son, Titus was himself a Praetorian prefect, they were ranked first.


Equipment and traditions

The Praetorian Guard, like all legionnaires, disposed of various equipment to execute different missions. More particularly as bodyguard, escort or reserve military force, they housed adaptable equipment for each function. For heavy packed combat infantry lines ( Triplex Acies System), they mounted helmets, armor (

specially in the 2nd and 3rd centuries), heavy colorful shields ( scuta), heavy javelins ( pila), and later even long spears and lighter javelins ( hasta, lancea). Praetorian Guard helmets included tall Galea with elaborate detail worked into the metal. Shields were ovoid and more robust compared with the regular rectangular shape sometimes used by the legions. Each legion had its own emblem displayed on its Scutum (shield) and the Praetorian Guard were probably the only unit to include additional insignia on their shields. Each cohort had their own version of Praetorian insignia. Praetorian Guard units could wear lion skin capes and their colours were so decorated with awards, that the men had difficulty in carrying them on long marches. The Praetorian Guard colours included the winged goddess of victory. For escorts, the oval shields and lances replaced the scuta and pila. Missions in Rome at the heart of the city in principle were forbidden to soldiers, so they wore a toga. The Praetorian Guard, like all legionaries, shared similar insignia, mainly on their shields.
