A Roman Gladiator was an ancient professional fighter who usually specialised with particular weapons and types of armour. They fought before the public in hugely popular organised games held in large purpose-built arenas throughout the Roman Empire from 105 BCE to 404 CE (official contests).

As fights were usually to the death, gladiators had a short life expectancy and so, although it was in some respects a glamorous profession, the majority of fighters were slaves, former slaves or condemned prisoners. Without doubt, gladiator spectacles were one of the most-watched forms of popular entertainment in the Roman world.
