A gladiator (Latin: gladiator, swordsman, from gladius, sword) was an armed combatant who entertained audiences in the Roman Republic and Roman Empire in violent confrontations with other gladiators, wild animals, and condemned criminals.
Early gladiators were prisoners of war or slaves or condemned criminals but soon free citizens became gladiators hoping to win fame and fortune. With the popularity of these games, the State assumed greater control, and gladiators were trained in imperial schools.
