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.
Originally they were two men chosen to sword-fight to the death as a funeral rite for an important Roman, with the belief that the slain man would accompany the important Roman in the afterlife. The name gladiator was taken from gladius, the name of the Roman infantry short sword. Later as these games became popular entertainment with several types of gladiators armed in various ways. Gladiators also fought against animals. Although seen rarely, the gladiatrix was a woman who fought in the arena.
