How Men Were Actually Selected to Become Roman Gladiators

Roman gladiators were initially chosen from a selection of criminals, slaves, prisoners of war, but later expanded to include volunteers.

Few spectacles in recorded history have grabbed people’s attention quite like the Roman gladiator games, a cultural force significant enough to leave its mark on Roman law, art, and politics. Yet for all the research done on what went down inside the arena, not nearly enough attention has been given to the system that produced its fighters. This was the calculated step-by-step process through which Rome selected the men destined to risk their lives on its arena floors.

 

What Was the Selection Process?

Gladiators were typically selected from pools of criminals, slaves, and prisoners of war. Many were chosen for this role as they never had the rights of a citizen and had no choice but to comply as recruits. The lanista (gladiator school owner) ran the ludus (gladiator school), and usually bought men in open slave markets. The buying and selling of gladiators happened all over the Roman Empire, and was kept under close watch by the government. Rome’s back-to-back battlefield wins kept gladiator inflows going as captured enemy soldiers were split up and some sent to fight in arenas. 

 

Many lanistae ran their gladiator crews with an iron fist, and held the legal power of life and death over every single person under their roof. Socially, they were the lowest of the low, thrown in the same bracket as pimps and actors. 

 

How Volunteers Became Gladiators

While most early fighters were enslaved people and convicted criminals, grave inscriptions indicate that by the 1st century AD, the recruiting process had started to change, with scores of free men beginning to voluntarily sign contracts with gladiator schools hoping to win fame and cash.

 

These volunteers included men facing severe economic hardships and ex-soldiers. They signed themselves over to a lanista under the auctoramentum gladiatorium. A voluntary contract typically spanning three years. Before being accepted, a volunteer would need a magistrate’s permission, after which he would undergo a physical exam to determine if he could handle the brutal training and fighting. The exam also decided what kind of training he would receive, since schools taught very specific styles that suited the height, build, and speed of each student. Once assigned a class, like the retiarius which involved fighting using fishing tools like a weighted net, trident, and dagger, a fighter typically could not switch styles.

The first gladiator schools, known as ludi, were established around the 2nd century BC. Upon arrival, gladiators were immediately assigned a specialized doctor, and placed under a lanista‘s watch. Fresh recruits entered as novicii and advanced to tirones gladiatores. When Augustus took power in 27 BC, the Roman government tightened its grip on public games, and growing numbers of gladiators were from then on trained in state-run schools. Experts estimate there were more than 100 gladiator schools across the Empire, with gladiators grouped into troupes called familia gladiatoria.

The Ludus Magnus was the top school in Rome. It was built by Emperor Domitian between 81 and 96 AD directly east of the Colosseum. Three other well-known schools ran alongside it – the Ludus Dacicus, the Ludus Gallicus, and the Ludus Matutinus. As a gladiator progressed, he climbed through training ranks called Palus, with Primus Palus being the highest, at which point he could teach and pass on his skills. Training was intense and open for the public to see. The Ludus Magnus, for example, seated around 3,000 spectators. Lanistae kept their men in good shape and well-fed, as they were to them serious financial investments.

 

Beyond fame and fortune, gladiators became part of a tight-knit group known for bravery and loyalty. While most had short lives, some won enough matches to earn freedom or a role as trainer, with the ultimate prize being the rudis, a wooden sword symbolizing hard-won freedom. 

 

How the Gladiator System Took Advantage of Human Suffering

What Rome had built was a system of carefully engineered human sourcing with one part slave market, one part military draft, one part voluntary contract. Recruitment into the ludus also worked through a coming-together of desperation and cold financial math.

 

This was by pulling together different kinds of outcasts into one unified machine of control. At a time when three out of every five people never even made it to their 20th birthday, the odds of a professional gladiator actually getting killed in any single fight, at least during the 1st century AD, were perhaps one in ten. Regardless of where they came from, gladiators gave the crowd a front-row seat at everything Rome valued such as mental and physical prowess, and bravery.
