s'' 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

, and starting from Septimius Severus, men were transferred from the Vigiles Urbanus, Urban Vigiles, Cohortes urbanae, Urban cohorts, and the various Roman legion, 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

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 good moral character, and come from a respectable family. In addition, he had to make use of all sorts of patronages available to him in order to obtain letters of recommendations from important leading figures in society. Once past the recruitment procedure he was designated as , and assigned as a (soldier) to one of the centuries of a cohort. 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 Military tribunes () at the head of the cohorts were Roman cavalrymen. In contrast to many superior cadres of the Army, who originated from the Equestrian Order, these tribunes started their career in the ranks of the Guard and were promoted from the ranks in the hierarchy. Next after becoming Centurions, they had to serve for a period of one year as superior centurions in one or several legions before achieving the status of (the highest ranked Centurion in a legion). Upon return to Rome, they occupied successively the positions of Tribunes of the Vigiles, Tribune of the Urban Cohort and finally Tribune of the Guard. 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 Roman military personal equipment, 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 (Roman infantry tactics, Triplex Acies System), they mounted helmets, armor (Lorica segmentata, Mail (armour), Lorica hamata, Lorica squamata specially in the 2nd and 3rd centuries), heavy colorful shields (Scutum (shield), scuta), heavy javelins (Pilum, pila), and later even long spears and lighter javelins (hasta (spear), hasta, lancea (weapon), lancea). Praetorian Guard helmets included tall Galea (helmet), 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 Victoria (mythology), 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. Praetorian Guard shields included Aquila (Roman), wings and thunderbolts, referring to
